1167 subprogram body that acts as its own spec may not have a non-private
1168 WITH clause on a private sibling.
1169 (Build_Unit_Name): If the parent unit in the name in a with_clause on a
1170 child unit is a renaming, create an implicit with_clause on that
1171 parent, and not on the unit it renames, to prevent visibility errors

1270 * sem_ch9.adb (Analyze_Requeue): Add a local flag to capture whether a
1271 requeue statement is dispatching. Do not emit an error when the name is

1273 perform subtype conformance between the formals of the current entry
1274 and those of the target interface primitive.
1275 (Analyze_Asynchronous_Select, Analyze_Conditional_Entry_Call, Analyze_
1276 Timed_Entry_Call): Analyze the triggering statement as the first step of
1277 the processing. If this is a dispatching select, postpone the analysis
1278 of all select statements until the Expander transforms the select. This
1279 approach avoids generating duplicate identifiers after the Expander has
1280 replicated some of the select statements. In case the Expander is
1281 disabled, perform regular analysis.
1282 (Check_Triggering_Statement): New routine.
1283 (Analyze_Requeue): Exclude any interpretations that are not entries when
1284 checking overloaded names in a requeue. Also test type conformance for

1290 * sem_disp.adb (Check_Dispatching_Call): If an actual in a call to an
1291 inherited operation is a defaulted tag-indeterminate call, and there is

1293 for the defaulted actual.
1295 2007-12-13 Geert Bosch <bosch@adacore.com>
1297 * sem_eval.adb (Eval_Real_Literal): N_Constant_Declaration is a static

1898 additional management on these nodes in Expand_Interface_Actuals.
1900 * exp_disp.adb (Expand_Interface_Actuals): Code cleanup. Remove code
1901 that handles use of 'Access and 'Unchecked_Access applied to

1947 vx_stack_info.{c,o} that contains the routine __gnat_get_stack_info

1949 able to extract the stack boundaries for stack checking.

1994 association for an access component, add an association with null as
1995 the expression. Remove testing for array subtypes and the setting in
1996 that case of Ctyp to the array component type, which prevented proper
1997 inclusion of an association for null-initialized arrays. Collapse
1998 condition that tests for array subtypes into just a test of
1999 Is_Partially_Initialized_Type (which already covers arrays anyway).

2119 * g-comlin.adb: (Start): Fix handling of empty command line.
2121 * gnatcmd.adb (GNATCmd): Do not put the -rules in the -cargs section,
2122 even when -rules follows the -cargs section.

2147 files instead of units to gigi.
2148 * gigi.h (struct File_Info_Type): New.
2149 (gigi): Rename and change type of number_units parameter, change
2150 type of file_info_ptr parameter.
2151 * trans.c (number_files): New global variable.
2152 (gigi): Rename and change type of number_units parameter, change
2153 type of file_info_ptr parameter.
2154 If mapped location support is enabled, create the isomorphic mapping
2155 between source files and line maps.
2156 (Sloc_to_locus): If mapped location support is enabled, translate
2157 source location into mapped location.
2158 (annotate_with_node): Rename into set_expr_location_from_node.

2184 * a-calend-vms.adb, a-calend.adb:
2185 Add a section on leap seconds control along with two entities used to
2186 enable and disable leap seconds support. The array Leap_Second_Times is
2187 now constant and contains hard time values pre-generated. Remove
2188 all elaboration code used to populate the table of leap seconds.
2191 Add entity Leap_Seconds_Support to the list of global run-time variables
2192 along with a comment on its usage and values.
2193 (Gen_Adainit_Ada): Add code to generate the declaration and import of

2207 s-taprop-solaris.adb, s-taprop-vms.adb, s-taprop-mingw.adb,
2208 s-taprop-posix.adb (Stop_Task): New function, dummy implementation.
2210 * s-taprop.ads, s-taprop-vxworks.adb (Stop_Task): New function.
2212 * s-tasdeb.adb (Stop_All_Tasks): New function, implementing a run-time
2213 function which can be called by the debugger to interrupt the tasks of
2214 an Ada application asynchronously, as needed on VxWorks.
2215 (Stop_All_Tasks_Handler): Renamed from Stop_All_Tasks.
2217 * s-tasdeb.ads (Stop_All_Tasks_Handler): New function declaration,

2234 * gnatvsn.ads (PCS_Version_Number, ASIS_Version_Number): Removed.
2236 * exp_dist.ads (PCS_Version_Number): Move from Gnatvsn to Exp_Dist,
2239 * opt.ads: Move ASIS_Version_Number from Gnatvsn into Tree_IO.
2241 * rtsfind.adb (PCS_Version_Number): Move from Gnatvsn to Exp_Dist,

2248 2007-09-26 Javier Miranda <miranda@adacore.com>
2249 Eric Botcazou <ebotcazou@adacore.com>
2252 (Get_HT_Link/Set_HT_Link): Updated to handle the additional level of
2253 indirection added to the HT_Link component of the TSD. This is required
2254 to statically allocate the TSD.
2257 Minor reordering of the declarations in the private part. Required to
2258 add a level of indirection to the contents of the TSD component HT_Link.
2259 This is required to statically allocate the TSD.
2261 * decl.c (gnat_to_gnu_entity) <object>: Do not exclude objects with
2262 Is_Statically_Allocated set from constant objects.
2263 Do not make exported constants created by the compiler volatile.
2264 (gnat_to_gnu_param): Do not treat an IN parameter whose address is taken
2267 * trans.c (Identifier_to_gnu): For constants, unshare initializers
2268 before returning them.
2270 * exp_disp.ads, exp_disp.adb (Building_Static_DT): Spec moved to the
2271 public part of the package.
2272 (Make_DT): Move HT_Link component out of the TSD record. For this
2273 purpose Make_DT now declares a separate object that stores the
2274 HT_Link value, and initializes the TSD component with the address
2275 of this new object. The addition of this level of indirection is
2276 required to statically allocate the TSD because the TSD cannot
2277 have variable components.
2278 (Expand_Interface_Conversion): Improve the expanded code.
2279 (Expand_Interface_Thunk): Set Is_Thunk in the thunk entity.
2281 * sem_disp.adb (Check_Dispatching_Operation): In case of a body
2282 declaring a primitive operation ---allowed by RM 3.9.2 (13.e/2)---,
2283 if we are building static dispatch tables then we must not generate
2284 extra code to register the primitive because the dispatch table will
2285 be built at the end of the library package; otherwise we notify that
2286 we cannot build the static dispatch table.
2288 2007-09-26 Robert Dewar <dewar@adacore.com>
2290 * checks.adb, gnat1drv.adb, sem_util.ads: Improve warnings for address

2305 for thunks associated with interface types.
2307 * einfo.ads: Improve documentatation of Is_Internal
2308 (Is_Thunk): New attribute applicable to subprograms. True for thunks
2309 associated with interface types.
2310 Extensive comment fixes regarding flags that appear in all entities. The
2311 documentation is now consistent for all such flags (there were a number
2312 of errors in the documentation in this regard).
2314 * exp_attr.adb (Expand_N_Attribute_Reference): Minor code cleanup.
2316 * exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any
2317 of these procedures are passed a function call that already has
2318 build-in-place actuals (testing new flag
2319 Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
2320 the case where processing continues.
2321 (Expand_Call): If the call is generated from a thunk body then we
2322 propagate the extra actuals associated with the accessibility
2323 level of the access type actuals.
2325 * sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field
2326 of each extra formal of a protected operation to reference the
2327 corresponding extra formal of the subprogram denoted by the
2328 operation's Protected_Body_Subprogram.
2330 * sinfo.ads, sinfo.adb (Is_Expanded_Build_In_Place_Call): New flag on
2331 N_Function_Call nodes.
2333 2007-09-26 Robert Dewar <dewar@adacore.com>
2335 * exp_ch5.adb: Activate memmove type processing if debug flag d.s is set
2337 * debug.adb: Add d.s flag.
2339 2007-09-26 Gary Dismukes <dismukes@adacore.com>
2341 * exp_dbug.adb (Debug_Renaming_Declaration): Set Is_Internal on the
2342 debug variable so that it won't be initialized when pragma
2343 Initialize_Scalars is in effect.
2345 2007-09-26 Gary Dismukes <dismukes@adacore.com>
2347 * freeze.adb (Freeze_Entity): Remove check for preelaborable
2348 initialization of a full view. This is moved to
2349 Analyze_Package_Specification.
2351 * sem_ch7.adb (Analyze_Package_Specification): Add check for
2352 preelaborable initialization of a full view in entity loop.
2353 (Uninstall_Declarations): If entity is a use-visible compilation unit,
2354 its child units are use-visible only if they are visible child units.
2356 * sem_util.adb (Is_Preelaborable_Expression): New function to determine
2357 whether an expression can be used within a type declaration that
2358 requires preelaborable init.
2359 (Check_Components): Replace inline code that does partial checking for
2360 preelaborable default expressions with call to
2361 Is_Preelaborable_Expression.
2362 (Has_Preelaborable_Initialization): In the case of a generic actual
2363 subtype, (that is, Is_Generic_Actual is True), return the result of
2364 applying Has_Preelaborable_Initialization to the generic actual's base
2367 2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
2369 * g-calend.adb (Has_53_Weeks): Rename to Last_Year_Has_53_Weeks. Add a
2370 call to Jan_1_Day _Of_Week to optimize its performance.
2371 (Is_Leap): Move the routine to the scope of Week_In_Year.
2372 (Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the
2373 weekday on which January 1 falls of Year - 1 and Year + 1. This function
2374 avoids calling Time_Of and Split, thus making it more efficent.
2375 (Week_In_Year): Reimplemented in oder to follow ISO 8601.
2377 * g-calend.ads (Week_In_Year): Change comment to reflect new
2380 2007-09-26 Emmanuel Briot <briot@adacore.com>
2382 * g-comlin.ads, g-comlin.adb (Command_Line_Configuration,
2383 Command_Line): New types
2384 (Define_Alias, Define_Prefix, Free): New subprograms. These provide
2385 support for defining how switches can be grouped on a command line (as
2386 is the case for -gnatw... for GNAT), and how simple switches can be
2387 used as aliases for more complex switches (-gnatwa is same as
2389 (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
2390 (Start, Current_*): New subprograms
2391 Added support for parsing an array of strings in addition to the real
2393 (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
2394 be moved from the body to the private part of the spec.
2395 (*): All subprograms now have an extra parameter with default value to
2396 specify which parser should be used. For backward compatibility, it
2397 defaults to parsing the command line of the application. They were also
2398 modified to properly handle cases where each of the argument does not
2399 start at index 1 (which is always true for Ada.Command_Line, but not
2400 when processing any Argument_List).
2401 (Free): New subprogram
2402 (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
2403 Argument): New subprograms
2404 (Switch_Parameter_Type): New enum, which clarifies the code. The extra
2405 special characters like ':', '=',... are now handled in a single place,
2406 which makes the code more extensible eventually.
2407 (Getopt, Full_Switch): When the switch was returned as part of the
2408 special character '*', make sure it is prepended by the switch character
2409 ('-' in general), so that the application knows whether "foo" or "-foo"
2410 was specified on the command line.
2412 2007-09-26 Florian Villoing <villoing@adacore.com>
2414 * g-dirope.adb (Remove_Dir): In case we are removing directories
2415 recursively, make sure that if an exception is raised during the
2416 processing, the current working directory is reset to its initial
2417 value before propagating the exception.
2419 2007-09-26 Vincent Celier <celier@adacore.com>
2421 * gnatbind.adb: If there are several ALI files specified and there is
2422 a main program to bind, the first ALI is expected to contain the main
2423 subprogram and the names of the binder generated files will be derived
2424 from the first ALI file name.
2425 (Gnatbind): Fix insertion character in invocation of Error_Msg
2427 2007-09-26 Vincent Celier <celier@adacore.com>
2429 * gnatcmd.adb (Check_Files): Do not include sources that have been
2430 removed by attributes Exclude_Source_Files or Locally_Removed_Files.
2432 2007-09-26 Ed Schonberg <schonberg@adacore.com>
2434 * lib-xref.ads, lib-xref.adb: The entry for array types now carries
2435 information about each of its index types, following the type
2436 reference for its component type.
2438 2007-09-26 Vincent Celier <celier@adacore.com>
2440 * make.adb: (Kill): New procedure (__gnat_kill imported)
2441 (Running_Compile, Outstanding_Compiles): Global variables that
2442 were previously local to procedure Compile_Sources.
2443 (Sigint_Intercepted): Send signal SIGINT to all outstanding
2444 compilation processes.
2446 (Gnatmake): If project files are used, create the mapping of all the
2447 sources, so that the correct paths will be found.
2449 * prj-env.ads, prj-env.adb (Create_Mapping): New procedure
2451 2007-09-26 Vincent Celier <celier@adacore.com>
2453 * makeutl.ads (Main_Config_Project): Moved to gpr_util.ads
2455 * prj.ads, prj.adb (Default_Language): Remove function, no longer used
2456 Replace components Compiler_Min_Options and Binder_Min_Options with
2457 Compiler_Required_Switches and Binder_Required_Switches in record
2459 Remove components Default_Language and Config in Project_Tree_Data,
2462 * prj-attr.adb: New attributes Required_Switches (<language>) in
2463 packages Compiler and Binder.
2465 * prj-nmsc.adb: Major rewrite of the processing of configuration
2466 attributes for gprbuild. No impact on GNAT tools.
2468 * prj-proc.ads, prj-proc.adb (Process_Project_Tree_Phase_2): No longer
2469 process configuration attributes: this is done in Prj.Nmsc.Check.

2471 being extended, instead of a shallow copy.
2472 (Process_Project_Tree_Phase_1): New procedure
2473 (Process_Project_Tree_Phase_1): New procedure
2474 (Process): Implementation now uses the two new procedures
2476 * prj-util.adb (Executable_Of): Get the suffix and the default suffix
2477 from the project config, not the tree config that no longer exists.
2479 2007-09-26 Vincent Celier <celier@adacore.com>

2500 2007-09-26 Ed Schonberg <schonberg@adacore.com>
2502 * sem_ch3.adb (Derive_Subprograms): If the interface parent is a direct
2503 ancestor of the derived type, the operations are inherited from the
2504 primary dispatch table of the parent.
2505 (OK_For_Limited_Init_In_05): Remove old comment. Reject in-place calls
2506 when the context is an explicit type conversion.
2508 2007-09-26 Ed Schonberg <schonberg@adacore.com>

2553 no sources, but is an extending project.
2555 2007-09-25 Eric Botcazou <ebotcazou@adacore.com>
2557 * trans.c: Fix misplaced #define.

2817 variable, insert init proc call only after the shared variable
2818 procedures have been processed, because the IP call needs to undergo

3015 to include loop parameters.
3016 (Valid_Conversion): Avoid generation of spurious error message.
3018 2007-08-31 Bob Duff <duff@adacore.com>
3020 * par-ch4.adb (P_Simple_Expression): Fold long sequences of
3021 concatenations of string literals into a single literal, in order to
3022 avoid very deep recursion in the front end, which was causing stack
3025 * sem_eval.adb (Eval_Concatenation): If the left operand is the empty
3026 string, and the right operand is a string literal (the case of "" &
3027 "..."), optimize by avoiding copying the right operand -- just use the
3028 value of the right operand directly.
3030 * stringt.adb (Store_String_Chars): Optimize by growing the
3031 String_Chars table all at once, rather than appending characters one by
3033 (Write_String_Table_Entry): If the string to be printed is very long,
3034 just print the first few characters, followed by the length. Otherwise,
3035 doing "pn(n)" in the debugger can take an extremely long time.
3037 * sem_prag.adb (Process_Interface_Name): Replace loop doing
3038 Store_String_Char with Store_String_Chars.
3040 2007-08-31 Vincent Celier <celier@adacore.com>

3052 clauses of subunits, ignore limited_with_clauses that are illegal and
3053 have not been fully analyzed.
3055 2007-08-31 Ed Schonberg <schonberg@adacore.com>
3057 * sem_ch3.adb: The predicate Is_Descendent_Of_Address is now an entity
3058 flag, for effiency. It is called when analyzing arithmetic operators
3059 and also for actuals in calls that are universal_integers. The flag is
3060 set for the predefined type address, and for any type or subtype
3063 * sem_ch4.adb (Analyze_One_Call): Reject an actual that is a
3064 Universal_Integer, when the formal is a descendent of address and the
3065 call appears in user code.
3066 (Analyze_Selected_Component): if the prefix is a private extension, the
3067 tag component is visible.
3069 * sem_util.ads, sem_util.adb: Remove Is_Descendent_Of_Address, now an
3072 2007-08-31 Robert Dewar <dewar@adacore.com>

3112 * gnat_ugn.texi: Add description for the new gnatpp
3113 '--separate-stmt-name' and '--use-on-new-line' options.

3128 * misc.c (gnat_type_max_size): Constify.
3130 2007-08-16 Gary Dismukes <dismukes@adacore.com>
3132 * cstand.adb (Create_Standard): Create an entity for a zero-sized type
3133 associated with Standard_Debug_Renaming_Type, to be used as the type of
3134 the special variables whose names provide debugger encodings for
3135 renaming declarations.
3137 * einfo.ads, einfo.adb (Debug_Renaming_Link): Change to return Node25.
3138 (Set_Debug_Renaming_Link): Change to set Node25.

3140 (Write_Field25_Name): Add case for E_Variable to output
3141 "Debug_Renaming_Link".
3142 (Write_Field23_Name): Correct the output string for "Limited_View".
3144 * exp_dbug.adb: Add with and use of Tbuild.
3145 (Debug_Renaming_Declaration): Replace creation of an enumeration type
3146 and literal with creation of a variable of type
3147 Standard_Debug_Renaming_Type whose name encodes both the renamed object
3148 and the entity of the renaming declaration.
3149 (Qualify_Entity_Name): Add the delayed qualification of the entity name
3150 part of the name of a variable that has a Debug_Renaming_Link.

3157 Ed Schonberg <schonberg@adacore.com>
3158 Javier Miranda <miranda@adacore.com>
3160 * exp_aggr.adb (Build_Record_Aggr_Code): Extend the test for an
3161 ancestor part given by an aggregate to test for an unchecked conversion,
3162 since this can occur in some cases when the ancestor part is a function
3163 call, and we don't want to fall into the recursive call to this
3164 procedure in that case.
3166 * exp_ch3.adb (Stream_Operation_OK): Revise tests for availability of
3167 stream attributes on limited types to account for user-specified
3168 attributes as well as whether Input (resp. Output) becomes available
3169 due to Read (resp. Write) being available for the type. Change Boolean
3170 variable to the more accurate name
3171 Has_Predefined_Or_Specified_Stream_Attribute. Change convoluted
3172 double-"not" predicate at beginning of return statement to more
3173 understandable form.
3175 * exp_ch5.adb (Expand_N_Extended_Return_Statement): If the extended
3176 return has an associated N_Handled_Sequence_Of_Statements, then wrap it
3177 in a block statement and use that as the first statement of the
3178 expanded return rather than incorrectly using the handled sequence as
3179 the first statement.
3181 * exp_ch6.adb (Expand_N_Subprogram_Declaration): If this is a protected
3182 operation, generate an explicit freeze node for it rather than
3183 generating extra formals, to ensure that gigi has the proper order of
3184 elaboration for anonymous subtypes in the signature of the subprograms.
3185 (Build_In_Place_Formal): Move assertion to beginning of loop.
3186 (Is_Build_In_Place_Function_Call): Allow for an unchecked conversion
3187 applied to a function call (occurs for some cases of 'Input).
3188 (Make_Build_In_Place_Call_In_*): Allow for an unchecked conversion
3189 applied to a function call (occurs for some cases of 'Input).
3191 * exp_strm.adb (Build_Record_Or_Elementary_Input_Function): For Ada
3192 2005, generate an extended return statement enclosing the result object
3195 * freeze.adb (Freeze_Record_Type): Extend the current management of
3196 components that are access type with an allocator as default value: add
3197 missing support to the use of qualified expressions of the
3198 allocator (which also cause freezing of the designated type!)
3199 (Freeze_Entity): Call Freeze_Subprogram in the case of a predefined
3200 dispatching operation, since extra formals may be needed by calls to
3201 build-in-place functions (such as stream 'Input).
3203 * sem_ch6.adb (Create_Extra_Formals): Skip creation of the extra
3204 formals for 'Constrained and accessibility level in the case of a
3205 predefined dispatching operation.
3207 * exp_util.adb (Insert_Actions): A protected body is a valid insertion
3208 point, no need to find the parent node.
3210 2007-08-16 Javier Miranda <miranda@adacore.com>
3212 * exp_attr.adb (Attribute_Priority): Add missing support for entries
3215 2007-08-16 Javier Miranda <miranda@adacore.com>
3217 * exp_ch9.adb (Build_Protected_Entry): Undo previous change because it
3218 is not really required and can introduce regression with the debugger.
3219 The original problem is fixed with the patch written for checks.adb.
3221 2007-08-16 Thomas Quinot <quinot@adacore.com>
3223 * g-dyntab.adb, g-table.adb, table.adb: (Set_Item): Suppress

3229 Including_Non_Switch set to False.
3230 (Gnatmake): For the compiler, call Test_If_Relative_Path with
3231 Including_Non_Switch set to False.
3233 * makeutl.adb, makeutl.ads (Test_If_Relative_Path): New Boolean
3234 parameter Including_Non_Switch, defaulted to True. When
3235 Including_Non_Switch is False, options that are not switches and
3236 appear as relative path are not converted to absolute paths.

3251 from the immediate ancestor of Main_Unit_Entity.
3252 (Install_Limited_Withed_Unit): Do not install the limited view of
3253 package P if P is reachable through an ancestor chain from package C
3254 and C also has a with clause for P in its body.
3255 (Has_Limited_With_Clause): New routine.
3256 (Has_With_Clause): New routine.
3258 2007-08-16 Ed Schonberg <schonberg@adacore.com>
3260 * sem_ch12.adb (Copy_Generic_Node): A reference to a child unit of the
3261 generic for an enclosing instance is a global reference, even though
3262 its scope is the enclosing instance.
3264 2007-08-16 Gary Dismukes <dismukes@adacore.com>
3265 Javier Miranda <miranda@adacore.com>
3267 * sem_ch3.adb (OK_For_Limited_Init_In_05): Allow calls to 'Input to
3268 initialize a limited object.
3269 (Build_Derived_Record_Type): Add missing check of rules ARM 3.9.4
3271 Make sure Has_Complex_Representation is inherited by derived type.

3278 2007-08-16 Ed Schonberg <schonberg@adacore.com>
3280 * sem_disp.adb (Check_Dispatching_Operation): If the operation
3281 implements an operation inherited from a progenitor interface, verify
3282 that they are subtype-conformant.

3285 Bob Duff <duff@adacore.com>
3286 Nicolas Setton <setton@adacore.com>
3288 * sem_res.adb (Comes_From_Predefined_Lib_Unit): New.
3289 (Resolve): Alphabetize local variables. Add new variable From_Lib. When
3290 the statement which is being resolved comes from a predefined library
3291 unit, all non-predefined library interpretations are skipped.
3292 (Resolve_Op_Concat): If string concatenation was folded in the parser,
3293 but the "&" is user defined, give an error, because the folding would
3296 * sinfo.ads, sinfo.adb (Is_Folded_In_Parser): New flag to indicate that
3297 the parser has folded a long sequence of concatenations of string
3300 * trans.c (Handled_Sequence_Of_Statements_to_gnu): Mark "JMPBUF_SAVE"
3301 and "JMP_BUF" variables as artificial.
3302 (N_String_Literal): Do not use alloca for very long string literals. Use
3303 xmalloc/free instead. Otherwise the stack might overflow.

3348 Ed Schonberg <schonberg@adacore.com>
3350 * inline.adb, types.ads, inline.ads, frontend.adb, alloc.ads:
3351 Suppress unmodified in-out parameter warning in some cases
3352 This patch is a also fairly significant change to the way suppressible
3355 * checks.ads, checks.adb (Install_Null_Excluding_Check): No check
3356 needed for access to concurrent record types generated by the expander.
3357 (Generate_Range_Check): When generating a temporary to capture the
3358 value of a conversion that requires a range check, set the type of the
3359 temporary before rewriting the node, so that the type is always
3360 properly placed for back-end use.
3361 (Apply_Float_Conversion_Check): Handle case where the conversion is
3363 (Get_Discriminal): Code reformatting. Climb the scope stack looking
3364 for a protected type in order to examine its discriminants.

3376 (Get_Allocator_Final_List): For the case of an anonymous access type
3377 that has a specified Associated_Final_Chain, do not go up to the
3379 (Expand_N_Type_Conversion): Test for the case of renamings of access
3380 parameters when deciding whether to apply a run-time accessibility
3382 (Convert_Aggr_In_Allocator): Use Insert_Actions to place expanded
3383 aggregate code before allocator, and ahead of declaration for
3384 temporary, to prevent access before elaboration when the allocator is
3385 an actual for an access parameter.
3386 (Expand_N_Type_Conversion): On an access type conversion involving an
3387 access parameter, do not apply an accessibility check when the
3388 operand's original node was an attribute other than 'Access. We now
3389 create access conversions for the expansion of 'Unchecked_Access and
3390 'Unrestricted_Access in certain cases and clearly accessibility should
3391 not be checked for those.
3393 * exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
3394 includes a type conversion of a packed component that has been expanded,
3395 recover the original expression for the object, and use this expression
3396 in the post-call assignment statement, so that the assignment is made
3397 to the object and not to a back-end temporary.
3398 (Freeze_Subprogram): In case of primitives of tagged types not defined
3399 at the library level force generation of code to register the primitive
3400 in the dispatch table. In addition some code reorganization has been
3401 done to leave the implementation clear.
3402 (Expand_Call): When expanding an inherited implicit conversion,
3403 preserve the type of the inherited function after the intrinsic
3404 operation has been expanded.
3406 * exp_ch2.ads, exp_ch2.adb
3407 (Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
3408 of an entry formal appearing in an assignment statement does not assign
3410 (Expand_Current_Value): Instead of calling a routine to determine
3411 whether the prefix of an attribute reference should be optimized or
3412 not, prevent the optimization of such prefixes all together.
3414 * lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
3415 component whose prefix is known to be of an access type is an implicit
3416 dereference and does not assign to the prefix.
3418 2007-08-14 Ed Schonberg <schonberg@adacore.com>
3419 Robert Dewar <dewar@adacore.com>
3421 * atree.ads, atree.adb (New_Copy_Tree): If hash table is being used and

3426 the corresponding range construct, and not to the aggregate itself. to
3427 maintain a one-to-one correspondence between itype and its associated
3428 node, to prevent errors when complex expression is copied.
3429 Fix mishandling of multiple levels of parens
3431 * sem_aggr.adb: Create a limited view of an incomplete type, to make
3432 treatment of limited views uniform for all visible declarations in a
3433 limited_withed package.
3434 (New_Copy_Tree): If hash table is being used and itype is visited,
3435 make an entry into table to link associated node and new itype.
3436 (Resolve_Record_Aggregate): Do not add an others box association for a
3437 discriminated record component that has only discriminants, when there
3438 is a box association for the component itself.
3440 * par-ch4.adb: Fix mishandling of multiple levels of parens
3442 2007-08-14 Robert Dewar <dewar@adacore.com>

3485 Warn on duplicate pragma Preelaborable_Initialialization
3487 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Body): Force the
3488 generation of a freezing node to ensure proper management of null
3489 excluding access types in the backend.
3490 (Create_Extra_Formals): Test base type of the formal when checking for
3491 the need to add an extra accessibility-level formal. Pass the entity E
3492 on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
3493 originally being done in a couple of cases), to ensure that the
3494 Extra_Formals list gets set on the entity E when the first entity is
3496 (Conforming_Types): Add missing calls to Base_Type to the code that
3497 handles anonymous access types. This is required to handle the
3498 general case because Process_Formals builds internal subtype entities
3499 to handle null-excluding access types.
3500 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
3501 functions that need it, even when not marked Requires_Overriding.
3502 Improve warnings for in out parameters

3507 (Analyze_Function_Return): Move call to Apply_Constraint_Check before
3508 the implicit conversion of the expression done for anonymous access
3509 types. This is required to generate the code of the null excluding
3510 check (if required).
3512 * sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
3513 A formal parameter is never publicly referenceable outside of its body.
3514 (Check_References): For an unreferenced formal parameter in an accept
3515 statement, use the same warning circuitry as for subprogram formal
3517 (Warn_On_Unreferenced_Entity): New subprogram, taken from
3518 Output_Unreferenced_Messages, containing the part of that routine that
3519 is now reused for entry formals as described above.
3520 (Goto_Spec_Entity): New function
3521 (Check_References): Do not give IN OUT warning for dispatching operation
3522 Improve warnings for in out parameters
3523 (Test_Ref): Check that the entity is not undefinite before calling
3524 Scope_Within, in order to avoid infinite loops.

3530 Gary Dismukes <dismukes@adacore.com>
3532 * exp_attr.adb (Expand_N_Attribute_Reference): Handle case of child unit
3533 (Expand_N_Attribute_Reference): Further unify the handling of the
3534 three forms of access attributes, using common code now for all three
3535 cases. Add a test for the case of applying an access attribute to
3536 an explicit dereference when the context is an access-to-interface
3537 type. In that case we need to apply the conversion to the prefix
3538 of the explicit dereference rather than the prefix of the attribute.
3539 (Attribute_Version, UET_Address): Set entity as internal to ensure
3540 proper dg output of implicit importation.
3541 (Expand_Access_To_Type): Removed.
3542 (Expand_N_Attribute_Reference): Merge the code from the three cases
3543 of access attributes, since the processing is largely identical for
3544 these cases. The substantive fix here is to process the case of a
3545 type name prefix (current instance case) before handling the case
3546 of interface prefixes.

3550 Javier Miranda <miranda@adacore.com>
3551 Robert Dewar <dewar@adacore.com>
3553 * exp_ch3.ads, exp_ch3.adb (Add_Final_Chain): New subprogram.
3554 (Freeze_Array_Type, Freeze_Record_Type): For the case of a component
3555 type that is an anonymous access to controlled object, establish
3556 an associated finalization chain to avoid corrupting the global
3557 finalization list when a dynamically allocated object designated
3558 by such a component is deallocated.
3559 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
3560 functions that need it, even when not marked Requires_Overriding.
3561 (Initialize_Tag): Replace call to has_discriminants by call to
3562 Is_Variable_Size_Record in the circuitry that handles the
3563 initialization of secondary tags.

3565 (Expand_N_Object_Declaration): Suppress call to init proc if there is a
3566 Suppress_Initialization pragma for a derived type.
3567 (Is_Variable_Size_Record): New subprogram.
3568 (Build_Offset_To_Top_Functions): New implementation that simplifies the
3569 initial version of this routine and also fixes problems causing
3570 incomplete initialization of the table of interfaces.
3571 (Build_Init_Procedure): Improve the generation of code to initialize the
3572 the tag components of secondary dispatch tables.
3573 (Init_Secondary_Tags): New implementation that simplifies the previous

3579 profile is a private type whose full view has not been analyzed yet.
3580 (Freeze_Array_Type): Generate init proc for packed array if either
3581 Initialize or Normalize_Scalars is set.
3582 (Make_Controlling_Function_Wrappers, Make_Null_Procedure_Specs): when
3583 constructing the new profile, copy the null_exclusion indicator for each
3584 parameter, to ensure full conformance of the new body with the spec.
3586 * sem_type.ads, sem_type.adb (Make_Controlling_Function_Wrappers):
3587 Create wrappers for constructor functions that need it, even when not
3588 marked Requires_Overriding.

3590 whose non-limited views are themselves incomplete types.
3591 (Add_Entry): Use an entity to store the abstract operation which hides
3593 (Binary_Op_May_Be_Hidden): Rename to Binary_Op_Interp_Has_Abstract_Op.

3611 abstract operators when trying to determine whether two types are
3613 (Has_Hidden_Interp): New routine.
3614 (Set_May_Be_Hidden_Interp): New routine.
3615 (Write_Overloads): Write the status of flag May_Be_Hidden.

3618 Javier Miranda <miranda@adacore.com>
3620 * exp_disp.ads, exp_disp.adb (Build_Dispatch_Tables): Handle tagged
3621 types declared in the declarative part of a nested package body or in
3622 the proper body of a stub.
3623 (Set_All_DT_Position): Add missing check to avoid wrong assignation
3624 of the same dispatch table slot to renamed primitives.
3625 (Make_Select_Specific_Data_Table): Handle private types.
3626 (Tagged_Kind): Handle private types.
3627 (Make_Tags, Make_DT): Set tag entity as internal to ensure proper dg
3628 output of implicit importation and exportation.
3629 (Expand_Interface_Thunk): Fix bug in the expansion assuming that the
3630 first formal of the thunk is always associated with the controlling
3631 type. In addition perform the following code cleanup: remove formal
3632 Thunk_Alias which is no longer required, cleanup evaluation of the
3633 the controlling type, and update the documentation.
3634 Replace occurrence of Default_Prim_Op_Count by
3635 Max_Predef_Prims. Addition of compile-time check to verify
3636 that the value of Max_Predef_Prims is correct.
3637 (Check_Premature_Freezing): Apply check in Ada95 mode as well.
3638 (Make_DT): Add parameter to indicate when type has been frozen by an
3639 object declaration, for diagnostic purposes.

3641 construction of statically allocated dispatch tables.
3642 (Make_DT): In case of library-level tagged types export the declaration
3643 of the primary tag. Remove generation of tags (now done by Make_Tags).
3644 Additional modifications to handle non-static generation of dispatch
3645 tables. Take care of building tables for asynchronous interface types
3646 (Make_Tags): New subprogram that generates the entities associated with
3647 the primary and secondary tags of Typ and fills the contents of Access_
3648 Disp_Table. In case of library-level tagged types imports the forward
3649 declaration of the primary tag that will be declared later by Make_DT.
3650 (Expand_Interface_Conversion): In case of access types to interfaces
3651 replace an itype declaration by an explicit type declaration to avoid
3652 problems associated with the scope of such itype in transient blocks.
3654 2007-08-14 Robert Dewar <dewar@adacore.com>
3655 Ed Schonberg <schonberg@adacore.com>
3656 Javier Miranda <miranda@adacore.com>
3658 * exp_util.ads, exp_util.adb:
3659 This patch replaces a number of occurrences of explicit tests for N_Null
3660 with calls to Known_Null. This improves tracking of null values, since
3661 Known_Null also catches null constants, and variables currently known to
3662 be null, so we get better tracking.
3663 (Ensure_Defined): create an itype reference only in the scope of the
3665 (Side_Effect_Free): A selected component of an access type that
3666 denotes a component with a rep clause must be treated as not
3667 side-effect free, because if it is part of a linked structure its
3668 value may be affected by a renaming.
3669 (Expand_Subtype_From_Expr): For limited objects initialized with build
3670 in place function calls, do nothing; otherwise we prematurely introduce
3671 an N_Reference node in the expression initializing the object, which
3672 breaks the circuitry that detects and adds the additional arguments to
3673 the called function. Bug found working in the new patch for statically
3674 allocated dispatch tables.
3675 (Is_Library_Level_Tagged_Type): New subprogram.
3676 (Remove_Side_Effects): If the expression of an elementary type is an
3677 operator treat as a function call.
3678 (Make_Literal_Range): If the index type of the array is not integer, use
3679 attributes properly to compute the constraint on the resulting aggregate
3682 * freeze.ads, freeze.adb (Freeze_Entity): If the entity is a
3683 class-wide type whose base type is an incomplete private type, leave
3684 class-wide type unfrozen so that freeze nodes can be generated
3685 properly at a later point.
3686 (Freeze_Entity, array case): Handle case of pragma Pack and component
3687 size attributre clause for same array.

4342 takes progenitor types into account.
4343 (Validate_Derived_Type_Instance): Enforce the rule of 3.9.3(9) by
4344 traversing over the primitives of the formal and actual types to locate
4345 any abstract subprograms of the actual type that correspond to a
4346 nonabstract subprogram of the formal type's ancestor type(s), and issue
4347 an error if such is found.
4348 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation,

4363 an access_to_constant type.
4364 (Try_Primitive_Operation): If the type of the prefix is a formal tagged
4365 type, the candidate operations are found in the scope of declaration of
4366 the type, because the type has no primitive subprograms.
4367 (Analyze_Selected_Component): If prefix is class-wide, and root type is
4368 a private extension, only examine visible components before trying to
4369 analyze as a prefixed call.
4370 Change Entity_List to Type_To_Use, for better readability.
4371 (Has_Fixed_Op): Use base type when checking whether the type of an
4372 operator has a user-defined multiplication/division

4383 (Missing_Read_Write_Attributes): A stream attribute is missing for the
4384 purpose of enforcing E.2.2(8) only if it is not available at any place.
4385 Take into account the Ada2005 pragma Has_Preelaborable_Initialization
4386 when checking the legality of an extension aggregate in a preelaborable
4387 package. Treat the literal null as a valid default expression in a
4388 component declaration for a type with preelaborable initialization.
4389 A limited interface is a legal progenitor for the designated type of a
4390 remote access to class-wide type.

4404 views that are themselves incomplete types.
4405 Handle interfaces visible through limited-with clauses.

4418 the allocator is not a coextension.
4419 (Resolve): Skip an interpretation hidden by an abstract operator only
4420 when the type of the interpretation matches that of the context.
4421 (Resolve): When looping through all possible interpretations of a node,
4422 do not consider those that are hidden by abstract operators.
4423 (Resolve_Actuals): When verifying that an access to class-wide object
4424 is an actual for a controlling formal, ignore anonymous access to
4425 subprograms whose return type is an access to class_wide type.
4426 (Resolve_Slice): If the prefix of the slice is a selected component
4427 whose type depends on discriminants, build its actual subtype before
4428 applying range checks on the bounds of the slice.

4430 to prevent anomalies between private and public views.

4451 elabration statements, register the package with the name server
4452 at the beginning, not at the end, of the elaboration statements so
4453 that they can create remote access to subprogram values that designate
4454 remote subprograms from the package.

5546 System_Restrictions and initialization of the data unless there is
5547 some use of System.Restrictions in the partition.

5583 bounds of the slice to construct the required constraint checks.
5584 Improve NOT NULL error messages
5585 (Apply_Constraint_Check): If the context is a null-excluding access
5586 type, diagnose properly the literal null.

5601 Eric Botcazou <ebotcazou@adacore.com>
5602 Arnaud Charlet <charlet@adacore.com>
5604 * einfo.ads, einfo.adb (Available_View): New synthesized attribute
5605 applicable to types that have the With_Type flag set. Returns the
5606 non-limited view of the type, if available, otherwise the type itself.
5607 For class-wide types, there is no direct link in the tree, so we have
5608 to retrieve the class-wide type of the non-limited view of the Etype.
5609 New attributes Static_Initialization and Static_Elaboration_Desired.
5610 Remove the pragma Thread_Body, and the associated flag
5611 Is_Thread_Body in entities, and all related code.

5621 components of records. Set to point to the entity of the corresponding
5623 (Is_By_Reference_Type): Recurse on the full view of an incomplete type.
5624 (Original_Access_Type): Remove, not needed.
5625 (Root_Type): Handle properly subtypes of class-wide-types.
5628 * sem_ch4.adb (Analyze_Explicit_Dereference): Add support for
5629 class-wide types visible through limited-with clauses.
5630 (Try_Primitive_Operation): When examining all primitive operations of a
5631 tagged type, do not consider subprograms labeled as hidden unless they
5632 belong to a private generic type with a tagged parent.
5633 (Try_Object_Operation): Extensive rewriting, to handle properly various
5634 overloading cases, when several ancestors may have class-wide operations
5635 that are possible candidates, and when the overloaded functions return
5636 array types and have defaulted parameters so that the call may be
5637 interpreted as an indexing.
5638 (Analyze_Allocator): Remove Mark_Allocator and its invocation.
5639 (Process_Function_Call): use Next, rather than Next_Actual, to analyze
5640 successive actuals before analyzing the call itself.
5641 (Try_Primitive_Operation): A primitive operation is compatible with the
5642 prefix if the prefix has a synchronized type and the type of the formal
5643 is its corresponding record, as can be the case when the primitive
5644 operation is declared outside of the body of the type.
5645 (Traverse_Homonyms): New subprocedure of Try_Class_Wide_Operation, to
5646 perform homonym traversal, looking for class-wide operation matches
5647 (formerly done in statements of Try_Class_Wide_Operation). Matches on
5648 access parameters are now restricted to anonymous access types.
5649 (Mark_Allocator): An allocator with a discriminant association parent is
5651 (Try_One_Prefix_Interpretation): If the type of the object is
5652 incomplete, as can be happen when it is a limited view obtained through
5653 a limited_with_clause, the selected component is not part of a prefixed
5655 (Complete_Object_Operation): Diagnose properly an object that is not
5656 aliased when the corresponding controlling formal is an access
5658 (Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly
5659 ambiguous calls in prefixed notation, where two primitives differ only
5660 in that the controlling argument of one is an access parameter.
5662 * sem_ch6.adb (Has_Single_Return): Add guard in code that determines
5663 whether a function that returns an unconstrained type can be inlined.
5664 (Process_Formals): Diagnose properly the illegal use of an incomplete
5665 type in the profile of an access_to_subprogram declaration.
5666 (Check_Synchronized_Overriding): Nothing check for concurrent types, the
5667 operations are attached to the corresponding record.
5668 (Analyze_Subprogram_Specification): Add variables Formal and Formal_Typ.
5669 When processing a primitive of a concurrent type which implements an
5670 interface change the type of all controlling formals to that of the
5671 corresponding record type.
5672 (Check_Synchronized_Overriding): Relax the conditional logic when trying
5673 to determine the tagged type to which a primitive belongs.
5674 (Check_Conventions): Capture condition to ignore a primitive operation
5675 (which is shared between the loop in Check_Conventions and the one in
5676 Check_Convention) in a new local function Skip_Check.
5677 (Check_Convention): Rename Prim_Op to Second_Prim_Op to avoid possible
5678 confusion with Check_Conventions' own Prim_Op local variable.
5679 (Create_Extra_Formals): Test for a tagged result type rather than a
5680 controlling result when determining whether to add a BIP_Alloc_Form
5681 formal and a BIP_Final_List formal to the function.
5682 (Check_Conformance); For parameters that are anonymous access types,
5683 subtype conformance requires that the not null and the constant
5684 indicators must match
5685 (Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
5686 to retrieve the appropriate type when processing a concurrent type
5687 declared within a generic. Minor comment reformatting. Change invocation
5688 of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
5690 (Analyze_Subprogram_Body): If the return type of a function is an
5691 anonymous access to the limited view of a class-wide type, and the
5692 non-limited view of the type is available, update the type of the
5693 function so that code can be generated.
5694 (Process_Formals): In case of access-subtype itype whose designated
5695 type is also an itype (situation that happens now with access to
5696 subprograms) we mark the access-type itype with the Has_Delayed_Freeze
5697 attribute to avoid backend problems.
5698 (Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
5699 init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
5700 anonymous types' designated types are same before testing
5701 Subtypes_Statically_Match.
5702 (Create_Extra_Formals): Test for a named access parameter that is a
5703 controlling formal as an additional condition for adding an
5704 accessibility level formal. This can occur in the subp type created for
5705 dispatching calls in Expand_Dispatching_Call, and allows calling
5706 Create_Extra_Formals from that procedure rather than special-casing the
5707 extra formals there.
5708 (Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
5709 when the function has a controlling result.
5710 (Check_Returns): Add much more knowledge of the optimization of local
5711 raise statements to gotos, to retain proper warnings in this case.
5712 (Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
5713 nodes when looking for last statement.
5715 * sem_type.ads, sem_type.adb (Specific_Type): Add support for
5716 class-wide types visible through limited with clauses.
5717 (Add_One_Interp): If the operands are anonymous access types, the
5718 predefined operator on universal_access is immediately visibles
5719 (Find_Unique_Type): Handle anonymous access to subprogram types just as
5720 other anonymous access types.
5721 (Disambiguate): Take into account CIL convention.
5722 (Interface_Present_In_Ancestor): Add support for class-wide interfaces.
5724 2007-06-06 Robert Dewar <dewar@adacore.com>

5729 Fix lower bound of tables.
5732 * nlists.adb: Ditto.
5733 (Prev_Node, Next_Node): Change index type to Int so that it properly
5734 covers the range First_Node_Id - 1 up.

5738 Bob Duff <duff@adacore.com>
5739 Hristian Kirtchev <kirtchev@adacore.com>
5741 * exp_aggr.ads, exp_aggr.adb:
5742 (Build_Record_Aggr_Code): Add missing initialization of secondary tags
5743 in extension aggregates.
5744 (Flatten): Other conditions being met, an aggregate is static if the
5745 low bound given by component associations is different from the low
5746 bound of the base index type.
5747 (Packed_Array_Aggregate_Handled): If the component type is itself a
5748 packed array or record, the front-end must expand into assignments.
5749 (Gen_Ctrl_Actions_For_Aggr): In call to Init_Controller, pass False to
5750 Init_Pr, instead of Ancestor_Is_Expression.
5751 (Gen_Ctrl_Actions_For_Aggr): When processing an aggregate of a
5752 coextension chain root, either generate a list controller or use the
5753 already existing one.
5754 (Static_Array_Aggregate): New procedure to construct a positional
5755 aggregate that can be handled by the backend, when all bounds and
5756 components are compile-time known constants.
5757 (Expand_Record_Aggregate): Force conversion of aggregates of tagged
5758 types covering interface types into assignments.
5759 (Replace_Type): move to Build_Record_Aggr_Code.
5760 (Expand_Record_Aggr_Code): if the target of the aggregate is an
5761 interface type, convert to the definite type of the aggregate itself,
5762 so that needed components are visible.
5763 (Convert_Aggr_In_Object_Decl): If the aggregate has controlled
5764 components and the context is an extended return statement do not
5765 create a transient block for it, to prevent premature finalization
5766 before the return is executed.
5767 (Gen_Assign): Do not generate a call to deep adjust routine if the
5768 component type is itself an array of controlled (sub)-components
5769 initialized with an inner aggregate.
5770 (Component_Check): New name for Static_Check. This name is now more
5771 appropriate, and documentation is added which was missing.
5772 (Component_Check): Add test for bit aligned component value
5773 (Component_Not_OK_For_Backend): Renames Has_Delayed_Nested_Aggregate_Or_
5774 Tagged_Comps, name is more appropriate given added function below.
5775 (Component_Not_OK_For_Backend): Check for bit aligned component ref.
5777 2007-06-06 Hristian Kirtchev <kirtchev@adacore.com>
5778 Javier Miranda <miranda@adacore.com>
5779 Robert Dewar <dewar@adacore.com>
5781 * exp_attr.adb (Expand_N_Attribute_Reference): Case Callable and
5782 Terminated: Add unchecked type conversion from System.Address to
5783 System.Tasking.Task_Id when calling the predefined primitive
5785 Disable new Ada 05 accessibility check for JVM.NET targets, which
5786 cannot be implemented in a practical way.
5787 (Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in
5788 the sources always references the tag of the actual object. Therefore,
5789 if 'Tag is applied in the sources to class-wide interface objects we
5790 generate code that displaces "this" to reference the base of the object.
5791 (Expand_N_Attribute_Reference, case Size): Return specified size if
5793 (Expand_N_Attribute_Reference): The expansion of the 'Address attribute
5794 has code that displaces the pointer of the object to manage interface
5795 types. However this code must not be executed when the prefix is a
5796 subprogram. This bug caused the wrong expansion of the internally
5797 generated assignment that fills the dispatch table when the primitive
5798 is a function returning a class-wide interface type.
5799 (Expand_N_Attribute_Reference:Attribute_Valid): Remove incorrect call to
5800 Set_Attribute_Name for Name_Unaligned_Valid.
5802 2007-06-06 Ed Schonberg <schonberg@adacore.com>
5803 Gary Dismukes <dismukes@adacore.com>
5805 * exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case 'Address):
5806 If the initialization is the equivalent aggregate of the initialization
5807 procedure of the type, do not remove it.
5808 (Expand_N_Attribute_Definition_Clause): Exclude access variables
5809 initialized to null from having their expression reset to empty and
5810 note this exception in the comment.

5820 references where the prefix must be a simple name.
5822 * sem_attr.ads, sem_attr.adb: Remove "with" and "use" clauses for
5823 Namet. Add new arrays Attribute_Name_Modifies_Prefix and
5824 Attribute_Requires_Simple_Name_Prefix.
5825 (Name_Modifies_Prefix): Body of new function.
5826 (Requires_Simple_Name_Prefix): Body of new function.
5827 (Resolve_Attribute, case Access): Improve error message for case of
5828 mismatched conventions.
5829 (Analyze_Attribute, case 'Tag): The prefix the attribute cannot be of an
5831 (Analyze_Attribute, case 'Access): If the type of the prefix is a
5832 constrained subtype for a nominal unconstrained type, use its base type
5833 to check for conformance with the context.
5834 (Resolve_Attribute): Remove test of the access type being associated
5835 with a return statement from condition for performing accessibility
5836 checks on access attributes, since this case is now captured by
5837 Is_Local_Anonymous_Access.
5838 (Analyze_Access_Attribute): Set Address_Taken on entity
5839 (Analyze_Attribute, case Address): Set Address_Taken on entity
5840 (OK_Self_Reference): Traverse tree to locate enclosing aggregate when
5841 validating an access attribute whose prefix is a current instance.
5842 (Resolve_Attribute): In case of attributes 'Code_Address and 'Address
5843 applied to dispatching operations, if freezing is required then we set
5844 the attribute Has_Delayed_Freeze in the prefix's entity.
5845 (Check_Local_Access): Set flag Suppress_Value_Tracking_On_Call in
5846 current scope if access of local subprogram taken
5847 (Analyze_Access_Attribute): Check legality of self-reference even if the
5848 expression comes from source, as when a single component association in
5849 an aggregate has a box association.
5850 (Resolve_Attribute, case 'Access): Do not apply accessibility checks to
5851 the prefix if it is a protected operation and the attribute is
5852 Unrestricted_Access.
5853 (Resolve_Attribute, case 'Access): Set the Etype of the attribute
5854 reference to the base type of the context, to force a constraint check
5855 when the context is an access subtype with an explicit constraint.
5856 (Analyze_Attribute, case 'Class): If the prefix is an interface and the
5857 node is rewritten as an interface conversion. leave unanalyzed after
5858 resolution, to ensure that type checking against the context will take

5862 Javier Miranda <miranda@adacore.com>
5863 Robert Dewar <dewar@adacore.com>
5865 * exp_ch3.adb (Make_Controlling_Function_Wrappers): generate wrapper a
5866 wrapper when the full view of the controlling type of an inherited
5867 function that dispatches on result implements interfaces.
5868 (Expand_N_Object_Declaration): In cases where the type of the
5869 declaration is anonymous access, create finalization list for it.
5870 (Expand_N_Object_Declaration): Generate a persistent_bss directive only
5871 if the object has no explicit initialization, to match description of
5872 functionality of pragam Persistent_BSS.
5873 (Build_Equivalent_Array_Aggregate, Build_Equivalent_Record_Aggregate):
5874 new function to build static aggregates, to replace initialization call
5875 when static initialization is desired.
5876 (Freeze_Type): Generate a list controller for an access type whenever
5877 its designated type has controlled anonymous access discriminants.
5878 (Build_Equivalent_Aggregate): New procedure to compute a static
5879 aggregate to be used as default initialization for composite types,
5880 instead of a generating a call to the initialization procedure for the
5882 (Build_Initialization_Call): When available, replace a call to the
5883 initialization procedure with a copy of the equivalent static aggregate
5885 (Expand_N_Object_Declaration): Use New_Occurrence_Of in generated
5886 declarations for objects of a class-wide interface type, rather than
5887 just identifiers, to prevent visibility problems.
5888 (Expand_N_Object_Declaration): When expanding the declaration for an
5889 object of a class-wide interface type, preserve the homonym chain of
5890 the original entity before exchanging it with that of the generated
5891 renaming declaration.
5892 (Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
5893 active, because there is no way to handle the exception.
5894 (Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
5895 to do a minimum decoration of the Access_Disp_Table list.
5896 (Expand_Record_Controller): Avoid the addition of the controller between
5897 the component containing the tag of a secondary dispatch table and its
5898 adjacent component that stores the offset to the base of the object.
5899 This latter component is only generated when the parent type has
5900 discriminants ---documented in Add_Interface_Tag_Components).
5901 (Apply_Array_Size_Check): Removed, no longer needed.
5902 (Expand_N_Full_Type_Declaration): If the type has anonymous access
5903 components, create a Master_Entity for it only if it contains tasks.
5904 (Build_Init_Procedure): Suppress the tag assignment compiling under
5906 (Freeze_Record_Type): Remove code associated with creation of dispatch
5908 (Init_Secondary_Tags): Update type of actuals when generating calls to
5909 Ada.Tags.Set_Offset_To_Top
5910 (Stream_Operation_OK): Disable use of streams compiling under no
5912 (Expand_N_Object_Declaration): Don't do Initialize_Scalars initalization
5913 if Has_Init_Expression set.
5914 (Build_Init_Procedure): Replace call to Fill_DT_Entry by call to
5915 Register_Primitive, which provides the same functionality.
5916 (Requires_Init_Proc): Return false in case of interface types.
5917 (Add_Secondary_Tables): Use the new attribute Related_Interface to
5919 (Predefined_Primitive_Freeze): Do not assume that an internal entity
5920 is always associated with a predefined primitive because the internal
5921 entities associated with interface types are not predefined primitives.
5922 Therefore, the call to Is_Internal is replaced by a call to the
5923 function Is_Predefined_Dispatching_Operation.
5924 (Make_Eq_If): When generating the list of comparisons for the
5925 components of a given variant, omit the controller component that is
5926 present if the variant has controlled components.
5928 2007-06-06 Javier Miranda <miranda@adacore.com>
5929 Hristian Kirtchev <kirtchev@adacore.com>
5930 Bob Duff <duff@adacore.com>
5932 * exp_ch4.adb (Complete_Coextension_Finalization): Add machinery to
5933 handle the creation of finalization lists and calls for nested
5934 coextensions when the root of the chains is part of a return statement.
5935 (Inside_A_Return_Statement): New function inside Complete_Coextension_
5937 (Expand_Record_Equality): Skip components that are interface types.
5938 (Displace_Allocator_Pointer): Add missing support for interface subtypes
5939 (Expand_N_Allocator): Replace invocation of Is_Local_Access_Discriminant
5940 with Rewrite_Coextension. Change the condition for detecting coextension
5942 (Is_Local_Access_Discriminant): Removed.
5943 (Rewrite_Coextension): New routine which rewrites a static coextension
5944 as a temporary and uses its unrestricted access in the construction of
5946 (Complete_Coextension_Finalization): New routine. Generate finalization
5947 attachment calls to all delayed coextensions.
5948 (Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
5949 the allocator is not a coextension itself and has delayed coextensions.
5950 If the current allocator is controlled, but also a coextension, delay
5951 the generation of the finalization attachment call.
5952 Rename local variable "Node" to "Nod" in order to avoid confusion with
5954 (Expand_Allocator_Expression): Call Adjust for initialized allocators of
5955 limited types that are not inherently limited. Such an allocator is
5956 illegal, but is generated by the expander for a return statement, to
5957 copy the result onto the secondary stack. This is the only case where a
5958 limited object can be copied. Generate code to displace the pointer
5959 to the object if the qualified expression is a class-wide interface
5960 object. Such displacement was missing and hence the copy of the object
5962 (Apply_Accessibility_Check): Handle allocated objects initialized in
5964 (Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
5965 and Expand_Allocator_Expression. Allocating class-wide interface objects
5966 this routine displaces the pointer to the allocated object to reference
5967 the component referencing the corresponding secondary dispatch table.
5968 Expand_Allocator_Expression): Add missing support to allocate class-wide
5969 interface objects initialized with a qualified expression.
5970 (Get_Allocator_Final_List): Test for an anonymous access type that is a
5971 function result type, and use the finalization list associated with the
5972 function scope in that case (such an anonymous type should not be
5973 treated like an access parameter's type).
5975 2007-06-06 Ed Schonberg <schonberg@adacore.com>
5976 Gary Dismukes <dismukes@adacore.com>
5977 Javier Miranda <miranda@adacore.com>
5979 * exp_ch5.adb (Expand_N_Assignment_Statement): For the assignment of a
5980 controlled type, use Make_Handler_For_Ctrl_Operation to construct the
5981 required exception handler.
5982 (Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
5983 properly the case of a function whose return type is a limited
5984 class-wide interface type. Modify the code of the accessibility
5985 check to handle class-wide interface objects. In this case we need to
5986 displace "this" to reference the primary dispatch table to get access
5987 to the TSD of the object (to evaluate its accessibility level).
5988 (Expand_N_Extended_Return_Statement): Test for a tagged result type
5989 rather than a controlling result as one of the conditions for
5990 generating tests of the implicit BIP_Alloc_Form formal. The
5991 initialization assignment is also handled according to whether the
5992 result is tagged instead of controlling.
5993 In the case where the init assignment is inserted in the "then" part of
5994 the allocation conditional, rewrite the target to be a dereference of
5995 the implicit BIP_Object_Access formal.
5996 If the returned value is unconstrained and created on the secondary
5997 stack, mark the enclosing block and function so that the secondary
5998 stack is not reclaimed on return.
5999 Treat returns from functions with controlling results similarly to
6000 returns from functions with unconstrained result subtypes.
6001 If the object returned is unconstrained, and an allocator must be
6002 created for it, analyze the allocator once the block for the extended
6003 return is installed, to ensure that finalizable components
6004 of the expression use the proper finalization list. Guard the call to
6005 Move_Final_List with a check that there is something to finalize.
6006 (Make_Tag_Ctrl_Assignment): Use "old" handling
6007 of controlled type assignment for virtual machines, since new code uses
6008 unsupported features (such as direct access to bytes in memory).
6010 2007-06-06 Gary Dismukes <dismukes@adacore.com>
6011 Ed Schonberg <schonberg@adacore.com>
6013 * exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
6014 accessibility actual, check for the case of an aliased object that has
6015 been rewritten as an Access attribute, and assign Prev to Prev_Orig so
6016 we fall into processing for the attribute rather than the name of the
6018 (Expand_Inline_Call): If an actual is a literal, and the corresponding
6019 formal has its address taken in the body, create a temporary to capture
6020 value. If the return type is a limited interface, do not treat the
6021 return value as Controlled.
6022 (Is_In_Place_Function): If the return type is a limited interface,
6023 treat as returning in place. The actual returned object may not always
6024 be limited, but the caller has to assume that it is returned in place.
6025 (Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
6026 context of an allocator, use the correct finalization chain (that is,
6027 the chain belonging to the access type, rather than the chain belonging
6028 to the current scope).
6029 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
6030 result type rather than a controlling result as a precondition for
6031 adding an allocation form actual to a build-in-place call.
6032 (Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
6033 (Freeze_Subprogram): Code cleanup. Remove all the code that register the
6034 primitive in the dispatch tables. This work is now done by Make_DT when
6036 (Register_Predefined_DT_Entry): Removed.
6037 (Add_Return): If end label is not present, use sloc of last statement
6038 for generated return statement in procedure, for better gdb behavior
6040 (Add_Access_Actual_To_Build_In_Place_Call): Set parent fields of the
6041 object address nodes to ensure proper processing by routines like
6043 (Expand_Call): Fix generation of validity check for parameter
6044 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Return without passing
6045 the allocation form parameter if the result subtype is constrained,
6046 except when the function has a controlling result.
6047 (Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
6048 rather than Is_Controlled and Has_Controlled_Component, since we want to
6049 include class-wide result types in this treatment. Also test for a
6050 controlling result, since that also requires passing a finalization
6052 (Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
6053 even when the result subtype is constrained, to handle calls involving
6054 controlling results.
6055 (Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
6056 is now called even when the result subtype is constrained, to handle
6057 calls involving controlling results.
6058 (Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
6059 on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure
6060 now performs the test).
6061 (Make_Build_In_Place_Call_In_Object_Declaration):
6062 Add_Alloc_Form_Actual_* is now called even when the result subtype is
6063 constrained, to handle calls involving controlling results.
6064 (Add_Return): Accomodate rewritten pattern from local raise to goto
6065 transformation, so that we still recognize an transfer statement
6066 and do the right thing here in that case.
6067 (Expand_N_Subprogram_Body): Add dummy Push/Pop_xxx_Label nodes at start
6068 and end of subprogram code.
6069 (Register_Interface_DT_Entry, Register_Predefined_DT_Entry): Add missing
6070 support for primitives that are functions (without formals) with a
6072 (Inherited_From_Formal): If the actual subtype has not generic parent
6073 type, it is not an actual for a formal derived type, and there is no
6074 operation to inherit from the formal.
6076 2007-06-06 Ed Schonberg <schonberg@adacore.com>
6077 Thomas Quinot <quinot@adacore.com>
6079 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): Set Sloc of
6080 inserted cleanup code appropriately for GDB use.
6081 (Make_Deep_Proc): Use Make_Handler_For_Ctrl_Operation to create
6082 exception handler for Deep_Adjust or Deep_Finalize.
6083 (Make_Handler_For_Ctrl_Operation): New subprogram. When runtime entity
6084 Raise_From_Controlled_Operation is available, use a call to that
6085 subprogram instead of a plain "raise Program_Error" node to raise
6086 Program_Error if an exception is propagated from an Adjust or Finalize
6088 (Insert_Actions_In_Scope_Around): If the statement to be wrapped
6089 appears in the optional statement list of a triggering alternative, the
6090 scope actions can be inserted directly there, and not in the list that
6091 includes the asynchronous select itself.
6093 2007-06-06 Ed Schonberg <schonberg@adacore.com>
6094 Robert Dewar <dewar@adacore.com>
6095 Hristian Kirtchev <kirtchev@adacore.com>
6097 * exp_ch9.ads, exp_ch9.adb (Build_Protected_Entry): Set sloc of
6098 generated exception handler appropriately when debugging generated code.
6099 Deal properly with No_Exception_Propagation restriction mode.
6100 (Expand_N_Abort_Statement): Add an unchecked type conversion from
6101 System.Address to System.Tasking.Task_Id when processing the result of
6102 the predefined primitive _disp_get_task_id.
6103 (Expand_N_Asynchronous_Select): Clarify comment.
6104 (Expand_N_Protected_Type_Declaration): Minor code cleanup.
6105 (Find_Parameter_Type): New routine inside Type_Conformant_Parameters.
6106 (Type_Conformant_Parameters): New parameter Prim_Op_Typ. Code cleanup.
6107 (Add_Private_Declarations, Build_Protected_Body): Use proper slocs for
6108 privals and for generated call to Complete_Entry_Body, for better gdb
6110 (Copy_Result_Type): Utility to construct a parameter and result profile
6111 for protected functions whose return type is an anonymous access to
6113 (Build_Protected_Sub_Spec and Expand_Access_Protected_Subprogram_Type):
6115 (Build_Task_Activation_Call): Insert Activate_Tasks call at proper
6116 point when the local-raise-to-goto transformation has taken place.
6118 2007-06-06 Javier Miranda <miranda@adacore.com>
6119 Nicolas Setton <setton@adacore.com>
6121 * exp_dbug.adb (Get_Encoded_Name): Modified to continue providing its
6122 functionality when the backend is generating code.
6123 Otherwise any serious error
6124 reported by the backend calling the frontend routine Error_Msg
6125 changes the Compilation_Mode to Check_Semantics, disables the
6126 functionality of this routine and causes the generation of
6127 spureous additional errors.
6129 * exp_dbug.ads (Pointers to Unconstrained Arrays): Document the
6130 debugging information now generated by the compiler for fat-pointer
6132 Document the contents of DW_AT_producer in the GNAT Vendor extensions to
6134 Document GNAT Vendor extensions to DWARF 2/3 and the "-gdwarf+" switch.
6136 2007-06-06 Thomas Quinot <quinot@adacore.com>

6139 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
6140 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
6141 For a remote call to a function with a classwide return type, apply an
6142 E.4(18) check to the returned value.
6143 (Add_RACW_Primitive_Declarations_And_Bodies): Do not generate stubs for
6144 stream attributes of the designated type of an RACW, as they are not
6145 dispatching primitive operations.
6147 2007-06-06 Geert Bosch <bosch@adacore.com>
6149 * exp_fixd.adb (Integer_Literal): Add optional argument to construct a
6151 (Do_Divide_Fixed_Fixed): Add comments to indicate Frac is always
6153 (Do_Divide_Fixed_Universal): Handle case of negative Frac.
6154 (Do_Multiply_Fixed_Fixed): Add coments to indicate Frac is always
6156 (Do_Multiply_Fixed_Universal): Handle case of negative Frac.
6158 2007-06-06 Javier Miranda <miranda@adacore.com>
6160 * exp_imgv.adb (Expand_Value_Attribute): Disable compilation of this
6161 attribute compiling package Ada.Tags under No_Run_Time_Mode.
6163 2007-06-06 Javier Miranda <miranda@adacore.com>
6165 * exp_intr.adb (Expand_Unc_Deallocation): Add missing support for
6166 deallocation of class-wide interface objects.
6167 (Expand_Dispatching_Constructor_Call): Take into account that if the
6168 result of the dispatching constructor is an interface type, the
6169 function returns a class-wide interface type; otherwise the returned
6170 object would be actual. The frontend previously accepted returning
6171 interface types because Expand_Interface_Actuals silently performed
6172 the management of the returned type "as if" it were a class-wide
6174 (Expand_Dispatching_Constructor_Call): Replace call to
6175 Make_DT_Access_Action by direct call to Make_Function_Call.
6177 2007-06-06 Robert Dewar <dewar@adacore.com>
6178 Ed Schonberg <schonberg@adacore.com>
6180 * exp_pakd.adb (Expand_Packed_Not): Use RM_Size rather than ESize to
6181 compute masking constant, since we now set Esize properly to the
6183 (Create_Packed_Array_Type): Set proper Esize value adjusted as required
6184 to match the alignment.
6185 (Create_Packed_Array_Type): Use Short_Short_Unsigned as base type for
6186 packed arrays of 8 bits or less.
6188 * freeze.adb (Freeze_Entity): When freezing the formals of a
6189 subprogram, freeze the designated type of a parameter of an access type
6190 only if it is an access parameter.
6191 Increase size of C convention enumeration object
6192 (Freeze_Entity, array type case): Make sure Esize value is properly
6193 adjusted for the alignment if it is known.
6194 (Freeze_Entity, array type case): When checking bit packed arrays for
6195 the size being incorrect, check RM_Size, not Esize.
6196 (Freeze_Record_Type): Check for bad discriminated record convention
6197 (In_Exp_Body): Return true if the body is generated for a subprogram
6198 renaming, either an attribute renaming or a renaming as body.
6199 (Check_Itype): If the designated type of an anonymous access component
6200 is a non-protected subprogram type, indicate that it is frozen, to
6201 prevent out-of-scope freeze node at some subsequent call.
6202 (Freeze_Subprogram): On OpenVMS, reject descriptor passing mechanism
6203 only if the subprogram is neither imported nor exported, as well as the
6204 NCA descriptor class if the subprogram is exported.

6211 * exp_prag.adb (Expand_Pragma_Import_Or_Interface): Remove properly a
6212 default initialization on an imported object, when there is no
6213 initialization call generated for it.
6214 (Expand_Pragma_Assert): Add handling of No_Exception_Propagation
6217 * snames.h, snames.ads, snames.adb, par-prag.adb: New pragma
6218 Static_Elaboration_Desired.
6219 Remove pragma Thread_Body.
6220 Implement a new pragma No_Body
6221 Removes the Explicit_Overriding pragma
6222 Remove Optional_Overriding pragma
6223 (Prag): Deal with Universal_Aliasing.
6224 (Name_CIL, Name_CIL_Constructor, Convention_CIL,
6225 Pragma_CIL_Constructor): New names.
6227 * sem_cat.adb (Validate_Object_Declaration): An initialization that
6228 uses the equivalent aggregate of a type must be treated as an implicit
6230 (Get_Categorization): Check a unit for pragma Preelaborate only if it
6231 has none of the other categories.
6232 (Process_Import_Or_Interface_Pragma): Report an error for an attempt
6233 to apply Import to an object renaming declaration.
6235 * sem_prag.adb (Process_Import_Or_Interface): Warn that a type imported
6236 from a C++ class should be declared as limited and that it will be
6237 considererd limited.
6238 (Analyze_Pragma): Warn that a type specified with pragma CPP_Class
6239 should be declared as limited and that it will be considererd limited.
6240 (Ada_2005_Pragma): New procedure, used to deal with Ada 2005 pragmas
6241 (Analyze_Pragma, case Export): Diagnose export of enumeration literal
6242 (Analyze_Pragma): Deal with Universal_Aliasing.
6243 (Sig_Flags): Likewise.
6244 (Set_Encoded_Interface_Name): Suppress encoding when compiling for AAMP.
6245 (Overflow_Checks_Unsuppressed): New flag.
6246 (Process_Suppress_Unsuppress): Set Overflow_Checks_Unsuppressed.
6247 (Analyze_Pragma [case Pack]): Ignore pragma Pack and post warning in
6248 case of JVM or .NET targets, and compiling user code.
6249 Add debugging convenience routine rv
6251 2007-06-06 Robert Dewar <dewar@adacore.com>
6253 * exp_strm.adb (Make_Field_Attributes): Avoid _Parent components that
6255 (Build_Elementary_Input_Call): For floating-point use right type in the
6256 absence of strange size or stream size clauses.
6257 (Build_Elementary_Write_Call): Same fix
6258 (Has_Stream_Standard_Rep): Returns False if Stream_Size attribute
6259 set to value that does not match base type size.
6261 2007-06-06 Ed Schonberg <schonberg@adacore.com>
6263 * exp_util.ads, exp_util.adb (Expand_Subtype_From_Expr): In Ada2005, an
6264 object of a limited type can be initialized with a call to a function
6265 that returns in place. If the limited type has unknown discriminants,
6266 and the underlying type is a constrained composite type, build an actual
6267 subtype from the function call, as is done for private types.
6268 (Side_Effect_Free): An expression that is the renaming of an object or
6269 whose prefix is the renaming of a object, is not side-effect free
6270 because it may be assigned through the renaming and its value must be
6271 captured in a temporary.
6272 (Has_Controlled_Coextensions): New routine.
6273 (Expand_Subtype_From_Expr): Do nothing if type is a limited interface,
6274 as is done for other limited types.
6275 (Non_Limited_Designated_Type): new predicate.
6276 (Make_CW_Equivalent_Type): Modified to handle class-wide interface
6278 Remove all handling of with_type clauses.
6280 * par-ch10.adb: Remove all handling of with_type clauses.

7930 required for a conversion between two access-to-unconstrained-array
7932 (Expr_Known_Valid): Validity checks do not apply to discriminants, but

8135 for all access attributes, because overload resolution should work the
8136 same for 'Access, 'Unchecked_Access, and 'Unrestricted_Access. This

8151 that use (a subtype of) the class-wide type of the enclosing type.

8153 Derived_Type for Prev formal on call to
8154 Check_Anonymous_Access_Components rather than Empty.
8155 (Make_Incomplete_Type_Declaration): Add test for case where the type has
8156 a record extension in deciding whether to create a class-wide type,
8157 rather than just checking Tagged_Present.

8159 to stand-alone object declarations as well as component declarations.

8204 (Compile): When compiling a predefined source, add -gnatpg
8205 as the second switch, after -c.
8206 (Compile_Sources): Allow compilation of Annex J renames without -a

8237 Unchecked_Conversion and Unchecked_Deallocation to be recompiled even
8238 when -gnatg is not specified.

8268 (Convert_Aggr_In_Allocator): If the allocator is for an access
8269 discriminant and the type is controlled. do not place on a finalization
8270 list at this point. The proper list will be determined from the

8290 parameter of the containing subprogram.
8291 (Expand_N_Op_Eq): Do nothing in case of dispatching call if compiling
8292 under No_Dispatching_Calls restriction. During the semantic analysis
8293 we already notified such violation.

8311 initialize most the TSD components by means of an aggregate.
8312 Modify the declaration of the object containing the TSD
8313 because we now expand code that has a higher level of abstraction.
8314 The TSD has a discriminant containing the Inheritance Depth Level,
8315 value that is used in the membership test but also to fix the size
8316 of the table of ancestors.
8317 (Expand_Interface_Conversion): Insert function body at the closest place
8318 to the conversion expression, to prevent access-before-elaboration
8319 errors in the backend.

8369 First/Next_Component_Or_Discriminant
8370 (Insert_Actions): Add entries for new N_Push and N_Pop nodes

8375 support concurrent types implementing interfaces.
8376 (Find_Implemented_Interface): Removed. All the calls to this subprogram

8380 CW_Or_Controlled_Type whenever the issue is related to
8381 using or not the secondary stack.

8397 anonymous, use finalization list of enclosing dynamic scope.
8398 (Expand_N_Package_Declaration): For a library package declaration
8399 without a corresponding body, generate RACW subprogram bodies in the
8400 spec (just as we do for the task activation call).
8401 (Convert_View): Split Is_Abstract flag into Is_Abstract_Subprogram and
8402 Is_Abstract_Type. Make sure these are called only when appropriate.
8403 Remove all code for DSP option

8420 Family_Size with 'Cap' set to true.
8421 (Expand_N_Protected_Type_Declaration, Expand_N_Protected_Body): Generate
8422 a protected version of an operation declared in the private part of
8423 a protected object, because they may be invoked through a callback.
8424 (Set_Privals): If the type of a private component is an anonymous access
8425 type, do not create a new itype for each protected body.
8426 If the body of a protected operation creates
8427 controlled types (including allocators for class-widetypes), the
8428 body of the corresponding protected subprogram must include a
8430 (Build_Activation_Chain_Entity): Build the chain entity for extended

8451 parameter that requires an extra constrained parameter, declare
8452 temporary for actual as a variable, not a constant.
8453 (Add_RACW_Primitive_Declarations_And_Bodies): Generate bodies only when
8454 the unit being compiled is the one that contains the stub type.

8467 registering the receiving stubs at the end of the 'Stmts' list.
8468 (RCI_Package_Locator): Pass the new Version generic formal when
8469 instantiating a RCI_Locator package.
8470 (Build_From_Any_Function): To compute the High bound for an
8471 unconstrained array actual, we add the Low bound with the length.
8472 Thus we must convert the low bound and the length to an appropriate
8473 type before doing the sum.
8474 (Build_Subprogram_Receiving_Stubs, PolyORB):
8475 * Retrieve the extra formals parameters at the
8476 end of the parameter stream.
8477 * Use Move_Any_Value to write back out parameters
8478 after executing the request as it is more efficient
8479 than Copy_Any_Value.
8480 * Build the any containing Extra Formals with the
8481 appropriate typecode.
8482 (PolyORB_Support.Helpers.Append_Record_Traversal): Nothing to do for an
8483 empty Component_List.

8497 (TC_Rec_Add_Process_Element, FA_Rec_Add_Process_Element,
8498 (FA_Ary_Add_Process_Element): When Datum is an Any, we cannot infer the
8499 typecode from the Etype. Therefore we retrieve the correct typecode
8500 with a call to Get_Any_Type.
8501 (Copy_Specification): Do controlling formal type substitution based on
8502 Is_Controlling_Formal flag, instead of caller-provided object type.
8503 (Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
8504 a RACW primitive operation, we might get a subprogram declaration for an
8505 ancestor of the RACW designated type (not for the designated type
8506 itself), in the case where this operation is inherited. In this case we
8507 have no easy means of determining the original tagged type for which
8508 the primitive was declared, so instead we now rely on
8509 Copy_Specification to use the Is_Controlling_Formal flag to determine
8510 which formals require type substitution.

8520 run-time subprogram CW_Membership by call to Build_CW_Membership.
8521 (Expand_Dispatching_Constructor_Call): If the dispatching tag is given

8523 Constructor_Call itself, to prevent out-of-order elaboration in the
8524 back-end when stack checking is enabled..

8648 This set of patch add support for the encoding form parameter.
8650 * mingw32.h (S2WSU): New macro to convert from a string to a
8651 wide-string using the UTF-8 encoding. The S2WS macro supports now only
8652 standard 8bits encoding.
8653 (WS2SU): As above but converting from wide-sring to string.
8654 This is needed as it is necessary to have access to both versions in the
8655 runtime for the form parameter encoding support.
8656 This set of patch add support for the encoding form parameter.
8657 (S2WS): Improve implementation to handle cases where the filename is not
8658 UTF-8 encoded. In this case we default to using the current code page
8661 * s-crtl-vms64.ads, s-crtl.ads (Filename_Encoding): New enumeration
8662 type (UTF8, ASCII_8bits). This enumeration has a rep clause to match
8663 the constants defined in adaint.h.

8671 corresponding encoding value into AFCB structure.
8672 (Reset): Pass the encoding value to freopen.

8706 * init.c: Reuse PA/HP-UX code for IA-64/HP-UX, except
8707 __gnat_adjust_context_for_raise.
8708 (__gnat_init_float): on x86 vxworks 5.x and 6.x, we use the same
8709 implementation of floating point operations as native x86 targets.
8710 So the FPU should be initialized in the same way using finit. Fix
8711 floating point operations accuracy issues.
8712 (__gnat_install_handler, case FreeBSD): Use proper type for sa_sigaction
8713 member in struct sigaction, so as to avoid warning for incompatible

8732 Modify the loop that collects type references, to include interface
8733 types that the type implements. List each of these interfaces when
8734 building the entry for the type.
8735 (Generate_Definition): Initialize component Def and Typ of new entry
8736 in table Xrefs, to avoid to have these components unitialized.
8737 (Output_References): Split Is_Abstract flag into
8738 Is_Abstract_Subprogram and Is_Abstract_Type.

8780 2007-04-06 Robert Dewar <dewar@adacore.com>
8782 * namet.ads, namet.adb (wn): Improve this debugging routine. Calling
8783 it no longer destroys the contents of Name_Buffer or Name_Len and
8784 non-standard and invalid names are handled better.
8785 (Get_Decoded_Name_String): Improve performance by using
8786 Name_Has_No_Encodings flag in the name table.
8787 (Is_Valid_Name): New function to determine whether a Name_Id is valid.
8788 Used for debugging printouts.
8790 2007-04-06 Robert Dewar <dewar@adacore.com>
8791 Javier Miranda <miranda@adacore.com>

8799 (P_Null_Exclusion): For AI-447: Remove warnings about "not null" being
8800 illegal in Ada 95, in cases where it is legal. Change the warnings to
8801 errors in other cases. Don't give the error unless the "not null"
8802 parses properly. Correct the source position at which the error occurs.
8803 (P_Known_Discriminant_Part_Opt): Pass Allow_Anonymous_In_95 => True to
8804 P_Null_Exclusion, to suppress "not null" warnings.

8935 full word is no longer compared twice.
8937 2007-04-06 Ed Schonberg <schonberg@adacore.com>
8939 * sem_ch10.adb (Install_Limited_Context_Clauses.
8940 Expand_Limited_With_Clause): Use a new copy of selector name in the
8941 call to Make_With_Clause. This fixes the tree structure for ASIS
8942 purposes. Nothing is changed in the compiler behaviour.
8943 (Process_Body_Clauses): Handle properly use clauses whose prefix is
8945 (Install_Limited_With_Clauses): Do not install non-limited view when it
8946 is still incomplete.
8948 2007-04-06 Ed Schonberg <schonberg@adacore.com>
8949 Gary Dismukes <dismukes@adacore.com>
8951 * sem_ch12.adb (Check_Generic_Actuals): Use first subtype of actual
8952 when capturing size information, instead of base type, which for a
8953 formal array type will be the unconstrained type.
8954 (Analyze_Formal_Object_Declaration): Add check for illegal default
8955 expressions for a formal in object of a limited type.
8956 (Instantiate_Object): Ditto.
8957 (Check_Formal_Package_Instance): Skip entities that are formal objects,
8958 because they were defaulted in the formal package and no check applies
8960 (Check_Formal_Package_Instance): Extend conformance check to other
8961 discrete types beyond Integer.
8962 (Process_Default): Copy directly the unmatched formal. A generic copy
8963 has already been performed in Analyze_Formal_Package.
8964 (Analyze_Associations): If a formal subprogram has no match, check for
8965 partial parametrization before looking for a default, to prevent
8967 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation): Do
8968 not set the instantiation environment before analyzing the actuals.
8969 Fixes regression on 8515-003 with implementation of AI-133.
8970 Set_Instance_Env checks whether the generic unit is a predefined
8971 unit, in which case the instance must be analyzed with the latest Ada
8972 mode. This setting must take place after analysis of the actuals,
8973 because the actuals must be analyzed and frozen in the Ada mode extant
8974 outside of the current instantiation.
8975 (Save_Env, Restore_Env): Preserve and restore the configuration
8976 parameters so that predefined units can be compiled in the proper Ada
8978 (Analyze_Formal_Object_Declaration,Analyze_Formal_Subprogram,
8979 Instantiate_Type): Split Is_Abstract flag into Is_Abstract_Subprogram
8980 and Is_Abstract_Type.
8981 (Analyze_Formal_Package): For better error recovery, Add exception
8982 handler to catch Instantion_Error, which can be raised in
8983 Analyze_Associations

8986 Bob Duff <duff@adacore.com>
8987 Gary Dismukes <dismukes@adacore.com>
8989 * sem_ch4.adb (Try_Primitive_Operation): The call is legal if the
8990 prefix type is a discriminated subtype of the type of the formal.
8991 (Analyze_Allocator): Collect all coextensions regardless of the context.
8992 Whether they can be allocated statically is determined in exp_ch4.
8993 (Analyze_Selected_Component): If the prefix is a limited view and the
8994 non-limited view is available, use the non-limited one.
8995 (Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
8996 therefore illegal), suggest a qualified expression rather than a type
8997 conversion, because a type conversion would be illegal in this context.
8998 (Anayze_Allocator): Trace recursively all nested allocators so that all
8999 coextensions are on the corresponding list for the root. Do no mark
9000 coextensions if the root allocator is within a declaration for a stack-
9001 allocated object, because the access discriminants will be allocated on
9003 (Analyze_Call): Remove restriction on calls to limited functions for the
9004 cases of generic actuals for formal objects, defaults for formal objects
9005 and defaults for record components.
9006 (Analyze_Allocator): Before analysis, chain coextensions on the proper
9007 element list. Their expansion is delayed until the enclosing allocator
9008 is processed and its finalization list constructed.
9009 (Try_Primitive_Operation): If the prefix is a concurrent type, looks
9010 for an operation with the given name among the primitive operations of
9011 the corresponding record type.
9012 (Analyze_Selected_Component): If the prefix is a task type that
9013 implements an interface, and there is no entry with the given name,
9014 check whether there is another primitive operation (e.g. a function)
9016 (Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
9017 properly the indexing of a function call written in prefix form, where
9018 the function returns an array type, and all parameters of the function
9019 except the first have defaults.
9020 (Analyze_Equality_Op): If this is a call to an implicit inequality, keep
9021 the original operands, rather than relocating them, for efficiency and
9022 to work properly when an operand is overloaded.
9023 (Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
9024 Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
9025 (Analyze_Selected_Component): If the prefix is a private extension, only
9026 scan the visible components, not those of the full view.
9027 (Try_Primitive_Operation): If the operation is a procedure, collect all
9028 possible interpretations, as for a function, because in the presence of
9029 classwide parameters several primitive operations of the type can match
9030 the given arguments.
9032 2007-04-06 Ed Schonberg <schonberg@adacore.com>
9033 Robert Dewar <dewar@adacore.com>
9035 * sem_ch5.adb (Analyze_Assignment): Reject a right-hand side that is a

9040 2007-04-06 Ed Schonberg <schonberg@adacore.com>
9041 Thomas Quinot <quinot@adacore.com>
9043 * sem_ch7.ads, sem_ch7.adb (Inspect_Deferred_Constant_Completion): Move
9044 out of Analyze_Package_Declaration, because processing must be applied
9045 to package bodies as well, for deferred constants completed by pragmas.
9046 (Analyze_Package_Declaration): When the package declaration being
9047 analyzed does not require an explicit body, call Check_Completion.
9048 (May_Need_Implicit_Body): An implicit body is required when a package
9049 spec contains the declaration of a remote access-to-classwide type.
9050 (Analyze_Package_Body): If the package contains RACWs, append the
9051 pending subprogram bodies generated by exp_dist at the end of the body.
9052 (New_Private_Type,Unit_Requires_Body): Split Is_Abstract flag into
9053 Is_Abstract_Subprogram and Is_Abstract_Type.
9054 (Preserve_Full_Attributes): The full entity list is not an attribute
9055 that must be preserved from full to partial view.
9057 * sem_dist.adb (Add_RAS_Dereference_TSS):
9058 Change primitive name to _Call so it cannot clash with any legal
9059 identifier, and be special-cased in Check_Completion.
9060 Mark the full view of the designated type for the RACW associated with
9061 a RAS as Comes_From_Source to get proper view switching when installing
9062 private declarations.
9063 Provite a placeholder nested package body along with the nested spec
9064 to have a place for Append_RACW_Bodies to generate the calling stubs
9065 and stream attributes.

9068 Robert Dewar <dewar@adacore.com>
9070 * sem_ch8.adb (Has_Components): If the argument is an incomplete type
9071 that is a limited view, check the non-limited view if available.
9072 (Undefined): Refine error message for missing with of Text_IO
9073 (Find_Expanded_Name): Use Is_Known_Unit for more accurate error message
9074 to distinguish real missing with cases.
9075 Fix format of all missing with messages
9076 (Analyze_Subprogram_Renaming): Emit proper error message on illegal
9077 renaming as body when renamed entity is abstract.
9079 2007-04-06 Ed Schonberg <schonberg@adacore.com>
9080 Javier Miranda <miranda@adacore.com>
9082 * sem_type.ads, sem_type.adb (Has_Abstract_Interpretation): Make
9083 predicate recursive, to handle complex expressions on literals whose
9084 spurious ambiguity comes from the abstract interpretation of some
9086 (Interface_Present_In_Ancestor): Add support to concurrent record
9088 (Add_One_Interp,Disambiguate): Split Is_Abstract flag into
9089 Is_Abstract_Subprogram and Is_Abstract_Type.
9091 2007-04-06 Ed Schonberg <schonberg@adacore.com>
9092 Javier Miranda <miranda@adacore.com>
9094 * sem_util.ads, sem_util.adb (Object_Access_Level): If the object is a
9095 dereference of a local object R created as a reference to another
9096 object O, use the access level of O.
9097 (Matches_Prefixed_View_Profile): Use common predicate Conforming_Types,
9098 rather than local Same_Formal_Type, to check whether protected operation
9099 overrides an inherited one.
9100 (Same_Formal_Type): New predicate, used when matching signatures of
9101 overriding synchronized operations, to handle the case when a formal
9102 has a type that is a generic actual.
9103 (Is_Aliased_View): Replace check on E_Task_Type and E_Protected_Type by
9104 predicate Is_Concurrent_Type. This ensures supportin case of subtypes.
9105 (Needs_One_Actual): New predicate, for Ada 2005 use, to resolve
9106 syntactic ambiguities involving indexing of function calls that return
9108 (Abstract_Interface_List): New subprogram that returns the list of
9109 abstract interfaces associated with a concurrent type or a
9110 concurrent record type.
9111 (Interface_Present_In_Parent): New subprogram used to check if a
9112 given type or some of its parents implement a given interface.
9113 (Collect_Abstract_Interfaces): Add support for concurrent types
9114 with interface types.
9115 (Has_Abstract_Interfaces): Add support for concurrent types with
9117 (Is_Parent): New subprogram that determines whether E1 is a parent
9118 of E2. For a concurrent type its parent is the first element of its

9460 anonymous access types.
9461 (Valid_Conversion): For a conversion to a numeric type occurring in an

10050 we request a discriminal value only in case of discriminants.
10051 (Apply_Discriminant_Check): For Ada_05, only call Get_Actual_Subtype for
10052 assignments where the target subtype is unconstrained and the target
10053 object is a parameter or dereference (other aliased cases are known
10054 to be unconstrained).

10168 the parent part is a build-in-place function call, generate assignments.
10169 (Expand_Record_Aggregate): Call Convert_To_Assignments if any components
10170 are build-in-place function calls.
10171 (Replace_Self_Reference): New subsidiary of
10172 Make_OK_Assignment_Statement, to replace an access attribute that is a
10173 self-reference into an access to the appropriate component of the
10174 target object. Generalizes previous mechanism to handle self-references
10175 nested at any level.
10176 (Is_Self_Referential_Init): Remove, not needed.
10177 (Is_Self_Referential_Init): New predicate to simplify handling of self
10178 referential components in record aggregates.
10179 (Has_Default_Init_Comps, Make_OK_Assignment_Statement): Add guard to
10180 check for presence of entity before checking for self-reference.
10181 (Has_Default_Init_Comps): Return True if a component association is a
10182 self-reference to the enclosing type, which can only come from a
10183 default initialization.
10184 (Make_OK_Assignment_Statement): If the expression is of the form
10185 Typ'Acc, where Acc is an access attribute, the expression comes from a
10186 default initialized self-referential component.
10187 (Build_Record_Aggr_Code): If the type of the aggregate is a tagged type
10188 that has been derived from several abstract interfaces we must also
10189 initialize the tags of the secondary dispatch tables.

10193 Javier Miranda <miranda@adacore.com>
10194 Robert Dewar <dewar@adacore.com>
10197 (Expand_Access_To_Protected_Op): If the context indicates that an access
10198 to a local operation may be transfered outside of the object, create an
10199 access to the wrapper operation that must be used in an external call.
10200 (Expand_N_Attribute_Reference, case Attribute_Valid): For the AAMP
10201 target, pass the Valid attribute applied to a floating-point prefix on
10202 to the back end without expansion.
10203 (Storage_Size): Use the new run-time function Storage_Size to retrieve
10204 the allocated storage when it is specified by a per-object expression.
10205 (Expand_N_Attribute_Reference): Add case for Attribute_Stub_Type.
10206 Nothing to do here, the attribute has been rewritten during semantic

10215 into a fat pointer.
10216 (Is_Constrained_Aliased_View): New predicate to help determine whether a
10217 subcomponent's enclosing variable is aliased with a constrained subtype.
10218 (Expand_N_Attribute_Reference, case Attribute_Constrained): For Ada_05,
10219 test Is_Constrained_Aliased_View rather than Is_Aliased_View, because
10220 an aliased prefix must be known to be constrained in order to use True
10221 for the attribute value, and now it's possible for some aliased views
10222 to be unconstrained.
10224 2006-10-31 Robert Dewar <dewar@adacore.com>
10226 * exp_ch2.adb: Change Is_Lvalue to May_Be_Lvalue
10227 (Expand_Entity_Reference): Correct error of not handling subprogram
10228 formals in current_value processing.

10233 Gary Dismukes <dismukes@adacore.com>
10235 * exp_ch3.ads, exp_ch3.adb (Expand_N_Object_Declaration): Do not
10236 register in the final list objects containing class-wide interfaces;
10237 otherwise we incorrectly register the tag of the interface in the final
10239 (Make_Controlling_Function_Wrappers): Add missing barrier to do not
10240 generate the wrapper if the parent primitive is abstract. This is
10241 required to report the correct error message.
10242 (Expand_N_Subtype_Indication): Do validity checks on range
10243 (Clean_Task_Names): If an initialization procedure includes a call to
10244 initialize a task (sub)component, indicate that the procedure will use
10245 the secondary stack.
10246 (Build_Init_Procedure, Init_Secondary_Tags): Enable full ABI
10247 compatibility for interfacing with CPP by default.
10248 (Expand_N_Object_Declaration): Only build an Adjust call when the
10249 object's type is a nonlimited controlled type.
10250 * exp_ch3.adb: Add with and use of Exp_Ch6.
10251 (Expand_N_Object_Declaration): Check for object initialization that is a
10252 call to build-in-place function and apply Make_Build_In_Place_Call_In_
10253 Object_Declaration to the call.
10254 (Freeze_Type): When the designated type of an RACW was not frozen at the
10255 point where the RACW was declared, validate the primitive operations
10256 with respect to E.2.2(14) when it finally is frozen.
10257 (Build_Initialization_Call,Expand_Record_Controller): Rename
10258 Is_Return_By_Reference_Type to be Is_Inherently_Limited_Type, because
10259 return-by-reference has no meaning in Ada 2005.
10260 (Init_Secondary_Tags): Add missing call to Set_Offset_To_Top
10261 to register tag of the immediate ancestor interfaces in the
10262 run-time structure.
10263 (Init_Secondary_Tags): Moved to the specification to allow the
10264 initialization of extension aggregates with abstract interfaces.
10265 (Build_Master_Renaming): Make public, for use by function declarations
10266 whose return type is an anonymous access type.
10267 (Freeze_Record_Type): Replace call to Insert_List_Before by call to
10268 Insert_List_Before_And_Analyze after the generation of the specs
10269 associated with null procedures.
10270 (Expand_Tagged_Root): Update documentation in its specification.
10271 (Init_Secondary_Tags): Update documentation.
10272 (Build_Init_Procedure): If we are compiling under CPP full ABI compa-
10273 tibility mode and the immediate ancestor is a CPP_Pragma tagged type
10274 then generate code to inherit the contents of the dispatch table
10275 directly from the ancestor.
10276 (Expand_Record_Controller): Insert controller component after tags of
10277 implemented interfaces.
10278 (Freeze_Record_Type): Call new procedure Make_Null_Procedure_Specs to
10279 create null procedure overridings when null procedures are inherited
10281 (Make_Null_Procedure_Specs): New procedure to generate null procedure
10282 declarations for overriding null primitives inherited from interfaces.
10283 (Is_Null_Interface_Procedure): New function in
10284 Make_Null_Procedure_Specs.
10285 (Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): If the
10286 immediate ancestor of a tagged type is an abstract interface type we
10287 must generate the specification of the predefined primitives associated
10288 with controlled types (because the dispatch table of the ancestor is
10289 null and hence these entries cannot be inherited). This is required to
10290 elaborate well the dispatch table.

10300 (Expand_N_In): Do validity checks on range
10301 (Expand_Selected_Component): Use updated for of Denotes_Discriminant.
10302 (Expand_N_Allocator): For "new T", if the object is constrained by
10303 discriminant defaults, allocate the right amount of memory, rather than
10304 the maximum for type T.
10305 (Expand_Allocator_Expression): Suppress the call to Remove_Side_Effects
10306 when the allocator is initialized by a build-in-place call, since the
10307 allocator is already rewritten as a reference to the function result,
10308 and this prevents an unwanted duplication of the function call.
10309 Add with and use of Exp_Ch6.
10310 (Expand_Allocator_Expresssion): Check for an allocator whose expression
10311 is a call to build-in-place function and apply
10312 Make_Build_In_Place_Call_In_Allocator to the call (for both tagged and
10313 untagged designated types).
10314 (Expand_N_Unchecked_Type_Conversion): Do not do integer literal
10315 optimization if source or target is biased.
10316 (Expand_N_Allocator): Add comments for case of an allocator within a
10317 function that returns an anonymous access type designating tasks.
10318 (Expand_N_Allocator): apply discriminant checks for access
10319 discriminants of anonymous access types (AI-402, AI-416)

10328 * exp_ch5.adb (Expand_N_Loop_Statement): Do validity checks on range
10329 (Expand_N_Assignment_Statement): Call
10330 Make_Build_In_Place_Call_In_Assignment if the right-hand side is a
10331 build-in-place function call. Currently, this can happen only for
10332 assignments that come from aggregates.
10333 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
10334 in order to alleviate the upward compatibility introduced by AI-318.
10335 (Expand_N_Extended_Return_Statement): Add support for handling the
10336 return object as a build-in-place result.
10337 (Expand_Non_Function_Return): Implement simple return statements nested
10338 within an extended return.
10339 (Enable_New_Return_Processing): Turn on the new processing of return
10341 (Expand_Non_Function_Return): For a return within an extended return,
10342 don't raise Program_Error, because Sem_Ch6 now gives a warning.
10343 (Expand_N_Extended_Return_Statement): Implement AI-318
10344 (Expand_Simple_Function_Return): Ditto.
10345 (Expand_N_If_Statement): Handle new -gnatwt warning

10347 (Expand_N_Assignment): Handle assignment to the Priority attribute of
10348 a protected object.
10349 (Expand_N_Assignment_Statement): Implement -gnatVe/E to control
10350 validity checking of assignments to elementary record components.
10351 (Expand_N_Return_Statement): return Class Wide types on the secondary
10352 stack independantly of their controlled status since with HIE runtimes,
10353 class wide types are not potentially controlled anymore.
10355 * expander.adb (Expand): Add case for new N_Extended_Return_Statement
10358 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Avoid
10359 Expand_Cleanup_Actions in case of N_Extended_Return_Statement, because
10360 it expects a block, procedure, or task. The return statement will get
10361 turned into a block, and Expand_Cleanup_Actions will happen then.

10365 Bob Duff <duff@adacore.com>
10366 Gary Dismukes <dismukes@adacore.com>
10368 * exp_ch6.ads, exp_ch6.adb: Use new Validity_Check suppression
10370 (Expand_Inlined_Call): Tagged types are by-reference types, and
10371 therefore should be replaced by a renaming declaration in the expanded
10372 body, as is done for limited types.
10373 (Expand_Call): If this is a call to a function with dispatching access
10374 result, propagate tag from context.
10375 (Freeze_Subprogram): Enable full ABI compatibility for interfacing with
10377 (Make_Build_In_Place_Call_In_Assignment): New procedure to do
10378 build-in-place when the right-hand side of an assignment is a
10379 build-in-place function call.
10380 (Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
10381 of the explicit dereference of the allocator to the result subtype of
10382 the build-in-place function. This is needed to satisfy type checking
10383 in cases where the caller's return object is created by an allocator for
10384 a class-wide access type and the type named in the allocator is a
10386 (Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
10387 conversion of the reference to the declared object to the result subtype
10388 of the build-in-place function. This is needed to satisfy type checking
10389 in cases where the declared object has a class-wide type. Also, in the
10390 class-wide case, change the type of the object entity to the specific
10391 result subtype of the function, to avoid passing a class-wide object
10392 without explicit initialization to the back end.
10393 (Register_Interface_DT_Entry): Moved outside the body of
10394 Freeze_Subprogram because this routine is now public; it is called from
10395 Check_Dispatching_Overriding to handle late overriding of abstract
10396 interface primitives.
10397 (Add_Access_Actual_To_Build_In_Place_Call): New utility procedure for
10398 adding an implicit access actual on a call to a build-in-place function.
10399 (Expand_Actuals): Test for an actual parameter that is a call to a
10400 build-in-place function and apply
10401 Make_Build_In_Place_Call_In_Anonymous_Context to the call.
10402 (Is_Build_In_Place_Function): New function to determine whether an
10403 entity is a function whose calls should be handled as build-in-place.
10404 (Is_Build_In_Place_Function_Call): New function to determine whether an
10405 expression is a function call that should handled as build-in-place.
10406 (Make_Build_In_Place_Call_In_Allocator): New procedure for handling
10407 calls to build-in-place functions as the initialization of an allocator.
10408 (Make_Build_In_Place_Call_In_Anonymous_Context): New procedure for
10409 handling calls to build-in-place functions in contexts that do not
10410 involve init of a separate object (for example, actuals of subprogram
10412 (Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
10413 handling calls to build-in-place functions as the initialization of an
10414 object declaration.

10416 instantiation of Traverse_Body to avoid unreferenced warning.
10417 (Check_Overriding_Inherited_Interfaces): Removed.
10418 (Register_Interface_DT_Entry): Code cleanup.
10419 (Register_Predefined_DT_Entry): Code cleanup.
10420 (Expand_Inlined_Call.Rewrite_Procedure_Call): Do not omit block around
10421 inlined statements if within a transient scope.
10422 (Expand_Inlined_Call.Process_Formals): When replacing occurrences of
10423 formal parameters with occurrences of actuals in inlined body, establish
10424 visibility on the proper view of the actual's subtype for the body's
10426 (Freeze_Subprogram): Do nothing if we are compiling under full ABI
10427 compatibility mode and we have an imported CPP subprogram because
10428 for now we assume that imported CPP primitives correspond with
10429 objects whose constructor is in the CPP side (and therefore we
10430 don't need to generate code to register them in the dispatch table).
10431 (Expand_Actuals): Introduce copy of actual, only if it might be a bit-
10432 aligned selected component.
10433 (Add_Call_By_Copy_Node): Add missing code to handle the case in which
10434 the actual of an in-mode parameter is a type conversion.
10435 (Expand_Actuals): If the call does not come from source and the actual
10436 is potentially misaligned, let gigi handle it rather than rejecting the
10437 (Expand_N_Subprogram_Body, Freeze_Subprogram): set subprograms returning
10438 Class Wide types as returning by reference independantly of their
10439 controlled status since with HIE runtimes class wide types are not
10440 potentially controlled anymore.
10442 2006-10-31 Ed Schonberg <schonberg@adacore.com>
10444 * exp_ch9.adb (Update_Prival_Types): Simplify code for entity
10445 references that are private components of the protected object.

10447 (Update_Prival_Subtypes): Add explicit Process argument to Traverse_Proc
10448 instantiation to deal with warnings.

10455 * exp_dbug.ads, exp_dbug.adb (Get_External_Name): Add missing
10456 initialization of Homonym_Len.
10457 (Fully_Qualify_Name): Remove kludge to eliminate anonymous block
10458 names from fully qualified name. Fixes problem of duplicate
10459 external names differing only in the presence of such a block name.
10461 2006-10-31 Thomas Quinot <quinot@adacore.com>
10462 Pablo Oliveira <oliveira@adacore.com>
10464 * exp_dist.adb (Get_Subprogram_Ids): This function will no more assign
10465 subprogram Ids, even if they are not yet assigned.
10466 (Build_Subprogram_Id): It is now this function that will take care of
10467 calling Assign_Subprogram_Ids if necessary.
10468 (Add_Receiving_Stubs_To_Declarations): Checking the subprograms ids
10469 should be done only once they are assigned.
10470 (Build_From_Any_Function, case of tagged types): Add missing call to

10473 type for an RACW type.
10474 (Add_RACW_Features): When processing an RACW declaration for which the
10475 designated type is already frozen, enforce E.2.2(14) rules immediately.
10476 (GARLIC_Support.Build_Subprogram_Receiving_Stubs): Do not perform any
10477 special reordering of controlling formals.
10479 * exp_dist.ads (Corresponding_Stub_Type): New subprogram. Returns the
10480 associated stub type for an RACW type.
10482 2006-10-31 Ed Schonberg <schonberg@adacore.com>
10484 * exp_fixd.adb (Rounded_Result_Set): For multiplication and division of
10485 fixed-point operations in an integer context, i.e. as operands of a
10486 conversion to an integer type, indicate that result must be rounded.
10488 2006-10-31 Robert Dewar <dewar@adacore.com>
10490 * exp_imgv.adb (Expand_Image_Attribute): For Wide_[Wide_]Character
10491 cases, pass the encoding method, since it is now required by the run
10494 * s-valwch.ads, s-valwch.adb (Value_Wide_Wide_Character): Avoid
10495 assumption that Str'First = 1.
10496 (Value_Wide_Character): Takes EM (encoding method) parameter and passes
10497 it on to the Value_Wide_Wide_Character call.
10498 (Value_Wide_Wide_Character): Takes EM (encoding method) parameter and
10499 properly handles a string of the form quote-encoded_wide_char-quote.
10501 * s-wchcnv.adb: Minor reformatting
10503 2006-10-31 Javier Miranda <miranda@adacore.com>
10505 * exp_intr.adb (Expand_Dispatching_Constructor_Call): Add missing
10506 run-time membership test to ensure that the constructed object
10507 implements the target abstract interface.
10509 2006-10-31 Robert Dewar <dewar@adacore.com>
10511 * exp_prag.adb (Expand_Pragma_Common_Object): Use a single
10512 Machine_Attribute pragma internally to implement the user pragma.
10513 Add processing for pragma Interface so that it is now completely
10514 equivalent to pragma Import.
10516 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Extend this pragma
10517 so that it can be applied to all entities, including record components
10518 and enumeration literals.
10519 (Analyze_Pragma, case Priority_Specific_Dispatching): Check whether
10520 priority ranges are correct, verify compatibility against task
10521 dispatching and locking policies, and if everything is correct an entry
10522 is added to the table containing priority specific dispatching entries
10523 for this compilation unit.
10524 (Delay_Config_Pragma_Analyze): Delay processing
10525 Priority_Specific_Dispatching pragmas because when processing the
10526 pragma we need to access run-time data, such as the range of
10527 System.Any_Priority.
10528 (Sig_Flags): Add Pragma_Priority_Specific_Dispatching.
10529 Allow pragma Unreferenced as a context item
10530 Add pragma Preelaborable_Initialization
10531 (Analyze_Pragma, case Interface): Interface is extended so that it is
10532 now syntactically and semantically equivalent to Import.
10533 (Analyze_Pragma, case Compile_Time_Warning): Fix error of blowups on
10534 insertion characters.
10535 Add handling for Pragma_Wide_Character_Encoding
10536 (Process_Restrictions_Restriction_Warnings): Ensure that a warning
10537 never supercedes a real restriction, and that a real restriction
10538 always supercedes a warning.
10539 (Analyze_Pragma, case Assert): Set Low_Bound_Known if assert is of
10542 2006-10-31 Bob Duff <duff@adacore.com>
10543 Ed Schonberg <schonberg@adacore.com>
10544 Robert Dewar <dewar@adacore.com>
10546 * exp_ch7.adb (Build_Array_Deep_Procs, Build_Record_Deep_Procs,
10547 Make_Deep_Record_Body): Rename Is_Return_By_Reference_Type to be
10548 Is_Inherently_Limited_Type, because return-by-reference has no meaning
10550 (Find_Node_To_Be_Wrapped): Use new method of determining the result
10551 type of the function containing a return statement, because the
10552 Return_Type field was removed. We now use the Return_Applies_To field.
10554 * exp_util.ads, exp_util.adb: Use new subtype N_Membership_Test
10555 (Build_Task_Image_Decl): If procedure is not called from an
10556 initialization procedure, indicate that function that builds task name
10557 uses the sec. stack. Otherwise the enclosing initialization procedure
10558 will carry the indication.
10559 (Insert_Actions): Remove N_Return_Object_Declaration. We now use
10560 N_Object_Declaration instead.
10561 (Kill_Dead_Code): New interface to implement -gnatwt warning for
10562 conditional dead code killed, and change implementation accordingly.
10563 (Insert_Actions): Add N_Return_Object_Declaration case.
10564 Correct comment to mention N_Extension_Aggregate node.
10565 (Set_Current_Value_Condition): Call Safe_To_Capture_Value to avoid bad
10566 attempts to save information for global variables which cannot be
10568 (Get_Current_Value_Condition): Handle conditions the other way round
10569 (constant on left). Also handle right operand of AND and AND THEN
10570 (Set_Current_Value_Condition): Corresponding changes
10571 (Append_Freeze_Action): Remove unnecessary initialization of Fnode.
10572 (Get_Current_Value_Condition): Handle simple boolean operands
10573 (Get_Current_Value_Condition): Handle left operand of AND or AND THEN
10574 (Get_Current_Value_Condition): If the variable reference is within an
10575 if-statement, does not appear in the list of then_statments, and does
10576 not come from source, treat it as being at unknown location.
10577 (Get_Current_Value_Condition): Enhance to allow while statements to be
10578 processed as well as if statements.
10579 (New_Class_Wide_Subtype): The entity for a class-wide subtype does not
10581 (OK_To_Do_Constant_Replacement): Allow constant replacement within body
10582 of loop. This is safe now that we fixed Kill_Current_Values.
10583 (OK_To_Do_Constant_Replacement): Check whether current scope is
10584 Standard, before examining outer scopes.
10586 2006-10-31 Vincent Celier <celier@adacore.com>
10588 * krunch.ads, krunch.adb (Krunch): New Boolean parameter VMS_On_Target.
10589 When True, apply VMS treatment to children of packages A, G, I and S.
10592 * fname-uf.adb (Get_File_Name): Call Krunch with OpenVMS_On_Target
10594 2006-10-31 Robert Dewar <dewar@adacore.com>
10595 Ed Schonberg <schonberg@adacore.com>
10597 * freeze.adb: Add handling of Last_Assignment field
10598 (Warn_Overlay): Supply missing continuation marks in error msgs
10599 (Freeze_Entity): Add check for Preelaborable_Initialization
10601 * g-comlin.adb: Add Warnings (Off) to prevent new warning
10603 * g-expect.adb: Add Warnings (Off) to prevent new warning
10605 * lib-xref.adb: Add handling of Last_Assignment field
10606 (Generate_Reference): Centralize handling of pragma Obsolescent here
10607 (Generate_Reference): Accept an implicit reference generated for a
10608 default in an instance.
10609 (Generate_Reference): Accept a reference for a node that is not in the
10610 main unit, if it is the generic body corresponding to an subprogram
10613 * xref_lib.adb: Add pragma Warnings (Off) to avoid new warnings
10615 * sem_warn.ads, sem_warn.adb (Set_Warning_Switch): Add processing for
10617 (Warn_On_Useless_Assignment): Suppress warning if enclosing inner
10619 (Output_Obsolescent_Entity_Warnings): Rewrite to avoid any messages on
10620 use clauses, to avoid messages on packages used to qualify, and also
10621 to avoid messages from obsolescent units.
10622 (Warn_On_Useless_Assignments): Don't generate messages for imported
10623 and exported variables.
10624 (Warn_On_Useless_Assignments): New procedure
10625 (Output_Obsolescent_Entity_Warnings): New procedure
10626 (Check_Code_Statement): New procedure
10628 * einfo.ads, einfo.adb (Has_Static_Discriminants): New flag
10629 Change name Is_Ada_2005 to Is_Ada_2005_Only
10630 (Last_Assignment): New field for useless assignment warning
10632 2006-10-31 Olivier Hainque <hainque@adacore.com>
10634 * g-alleve.adb (lvx, stvx): Ceil-Round the Effective Address to the
10635 closest multiple of VECTOR_ALIGNMENT and not the closest multiple of 16.
10637 2006-10-31 Bob Duff <duff@adacore.com>
10638 Robert Dewar <dewar@adacore.com>
10639 Ed Schonberg <schonberg@adacore.com>
10641 * g-awk.adb (Default_Session, Current_Session): Compile this file in
10642 Ada 95 mode, because it violates the new rules for AI-318.
10644 * g-awk.ads: Use overloaded subprograms in every case where we used to
10645 have a default of Current_Session. This makes the code closer to be
10646 correct for both Ada 95 and 2005.
10648 * g-moreex.adb (Occurrence): Turn off warnings for illegal-in-Ada-2005
10649 code, relying on the fact that the compiler generates a warning
10650 instead of an error in -gnatg mode.
10652 * lib-xref.ads (Xref_Entity_Letters): Add entry for new
10653 E_Return_Statement entity kind.
10654 Add an entry for E_Incomplete_Subtype in Xref_Entity_Letters.
10656 * par.adb (P_Interface_Type_Definition): Addition of one formal to
10657 report an error if the reserved word abstract has been previously found.
10658 (SS_End_Type): Add E_Return for new extended_return_statement syntax.
10660 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve message for
10661 parenthesized range attribute usage
10662 (P_Expression_No_Right_Paren): Add missing comment about error recovery.
10664 * par-ch6.adb (P_Return_Object_Declaration): AI-318: Allow "constant"
10665 in the syntax for extended_return_statement. This is not in the latest
10666 RM, but the ARG is expected to issue an AI allowing this.
10667 (P_Return_Subtype_Indication,P_Return_Subtype_Indication): Remove
10668 N_Return_Object_Declaration. We now use N_Object_Declaration instead.
10669 (P_Return_Object_Declaration, P_Return_Subtype_Indication,
10670 P_Return_Statement): Parse the new syntax for extended_return_statement.
10672 * par-endh.adb (Check_End, Output_End_Deleted, Output_End_Expected,
10673 Output_End_Missing): Add error-recovery code for the new
10674 extended_return_statement syntax; that is, the new E_Return entry on
10677 * s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from
10678 limited to nonlimited, because otherwise we violate the new Ada 2005
10679 rules about returning limited types in function Create_AST_Handler in
10682 * sem.adb (Analyze): Add cases for new node kinds
10683 N_Extended_Return_Statement and N_Return_Object_Declaration.
10685 * sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
10686 type is in the same category as type of context before applying check,
10687 to prevent anomalies in instantiations.
10688 (Resolve_Aggregate): Remove test for limited components in aggregates.
10689 It's unnecessary in Ada 95, because if it has limited components, then
10690 it must be limited. It's wrong in Ada 2005, because limited aggregates
10692 (Resolve_Record_Aggregate): Move check for limited types later, because
10693 OK_For_Limited_Init requires its argument to have been resolved.
10694 (Get_Value): When copying the component default expression for a
10695 defaulted association in an aggregate, use the sloc of the aggregate
10696 and not that of the original expression, to prevent spurious
10697 elaboration errors, when the expression includes function calls.
10698 (Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
10699 were missing. We also didn't handle qualified expressions. Now also
10700 allow function calls. Use new common routine OK_For_Limited_Init.
10701 (Resolve_Extension_Aggregate): Minor fix to bad error message (started
10702 with space can upper case letter).
10704 * sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set
10705 Has_Static_Discriminants flag
10706 (Record_Type_Declaration): Diagnose an attempt to declare an interface
10707 type with discriminants.
10708 (Process_Range_Expr_In_Decl): Do validity checks on range
10709 (Build_Discriminant_Constraints): Use updated form of
10710 Denotes_Discriminant.
10711 (Process_Subtype): If the subtype is a private subtype whose full view
10712 is a concurrent subtype, introduce an itype reference to prevent scope
10714 (Build_Derived_Record_Type, Collect_Interface_Primitives,
10715 Record_Type_Declaration): The functionality of the subprograms
10716 Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
10717 is now performed by a single routine.
10718 (Build_Derived_Record_Type): If the type definition includes an explicit
10719 indication of limitedness, then the type must be marked as limited here
10720 to ensure that any access discriminants will not be treated as having
10721 a local anonymous access type.
10722 (Check_Abstract_Overriding): Issue a detailed error message when an
10723 abstract subprogram was not overridden due to incorrect mode of its
10725 (Analyze_Private_Extension_Declaration): Add support for the analysis of
10726 synchronized private extension declarations. Verify that the ancestor is
10727 a limited or synchronized interface or in the generic case, the ancestor
10728 is a tagged limited type or synchronized interface and all progenitors
10729 are either limited or synchronized interfaces.
10730 Derived_Type_Declaration): Check for presence of private extension when
10731 dealing with synchronized formal derived types.
10732 Process_Full_View): Enchance the check done on the usage of "limited" by
10733 testing whether the private view is synchronized.
10734 Verify that a synchronized private view is completed by a protected or
10736 (OK_For_Limited_Init_In_05): New function.
10737 (Analyze_Object_Declaration): Move check for limited types later,
10738 because OK_For_Limited_Init requires its argument to have been resolved.
10739 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
10740 in order to alleviate the upward compatibility introduced by AI-318.
10741 (Constrain_Corresponding_Record): If the constraint is for a component
10742 subtype, mark the itype as frozen, to avoid out-of-scope references to
10743 discriminants in the back-end.
10744 (Collect_Implemented_Interfaces): Protect the recursive algorithm of
10745 this subprogram against wrong sources.
10746 (Get_Discr_Value, Is_Discriminant): Handle properly references to a
10747 discriminant of limited type completed with a protected type, when the
10748 discriminant is used to constrain a private component of the type, and
10749 expansion is disabled.
10750 (Find_Type_Of_Object): Do not treat a return subtype that is an
10751 anonymous subtype as a local_anonymous_type, because its accessibility
10752 level is the return type of the enclosing function.
10753 (Check_Initialization): In -gnatg mode, turn the error "cannot
10754 initialize entities of limited type" into a warning.
10755 (OK_For_Limited_Init): Return true for generated nodes, since it
10756 sometimes violates the legality rules.
10757 (Make_Incomplete_Declaration): If the type for which an incomplete
10758 declaration is created happens to be the currently visible entity,
10759 preserve the homonym chain when removing it from visibility.
10760 (Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
10761 inherited subprograms.
10762 (Access_Definition): If this is an access to function that is the return
10763 type of an access_to_function definition, context is a type declaration
10764 and the scope of the anonymous type is the current one.
10765 (Analyze_Subtype_Declaration): Add the defining identifier of a regular
10766 incomplete subtype to the set of private dependents of the original
10768 (Constrain_Discriminated_Type): Emit an error message whenever an
10769 incomplete subtype is being constrained.
10770 (Process_Incomplete_Dependents): Transform an incomplete subtype into a
10771 corresponding subtype of the full view of the original incomplete type.
10772 (Check_Incomplete): Properly detect invalid usage of incomplete types
10775 2006-10-31 Hristian Kirtchev <kirtchev@adacore.com>
10777 * g-catiio.ads, g-catiio.adb (Value): New function.

10786 Robert Dewar <dewar@adacore.com>
10788 * gnatcmd.adb (Process_Link): Use Osint.Executable_Name instead of
10789 handling executable extension manually and duplicating code.
10791 * make.adb: Implement new -S switch
10792 (Gnatmake): Use new function Osint.Executable_Name instead
10793 of handling executable extension manually.
10795 * prj-util.adb (Executable_Of): Make sure that if an Executable_Suffix
10796 is specified, the executable name ends with this suffix.
10797 Take advantage of Osint.Executable_Name instead of duplicating code.
10799 * switch-m.adb: Recognize new gnatmake -S switch
10801 * targparm.ads, targparm.adb (Executable_Extension_On_Target): New
10803 (Get_Target_Parameters): Set Executable_Extension_On_Target if
10806 * makeusg.adb: Add line for gnatmake -S switch
10808 2006-10-31 Vincent Celier <celier@adacore.com>
10810 * gnatlink.adb (Gnatlink): If gcc is not called with -shared-libgcc,
10811 call it with -static-libgcc, as there are some platforms, such as
10812 Darwin, where one of these two switches is compulsory to link.
10814 2006-10-31 Vincent Celier <celier@adacore.com>
10816 * gnatls.adb: Take into account GPR_PROJECT_PATH, when it is defined,
10817 instead of ADA_PROJECT_PATH, for the project path.
10818 (Gnatls): When displaying the project path directories, use host dir
10821 * prj-ext.adb (Prj.Ext elaboration): On VMS, only expand relative path
10822 names in the project path, as absolute paths may correspond to
10823 multi-valued VMS logical names.
10825 2006-10-31 Vincent Celier <celier@adacore.com>
10827 * g-os_lib.ads, g-os_lib.adb (Locate_Exec_On_Path): Always return an
10828 absolute path name.
10829 (Locate_Regular_File): Ditto
10830 (Change_Dir): Remove, no longer used
10831 (Normalize_Pathname): Do not use Change_Dir to get the drive letter
10832 on Windows. Get it calling Get_Current_Dir.
10833 (OpenVMS): Remove imported boolean, no longer needed.
10834 (Normalize_Pathname)[VMS]: Do not resolve directory names.
10835 (Pid_To_Integer): New function to convert a Process_Id to Integer
10837 2006-10-31 Thomas Quinot <quinot@adacore.com>
10839 * g-socket.ads, g-socket.adb (Close_Selector): Once the signalling
10840 sockets are closed, reset the R_Sig_Socket and W_Sig_Socket components
10842 (Selector_Type): Add default value of No_Socket for R_Sig_Socket and
10845 2006-10-31 Robert Dewar <dewar@adacore.com>
10847 * g-speche.ads, g-speche.adb: Add special case to recognize misspelling
10848 initial letter o as a zero.
10850 2006-10-31 Robert Dewar <dewar@adacore.com>
10852 * g-spipat.adb (S_To_PE): Remove incorrect use of 0 instead of Str'First
10854 2006-10-31 Robert Dewar <dewar@adacore.com>
10856 * layout.adb (Layout_Record_Type): Deal with non-static subtypes of
10858 (Layout_Variant_Record): Retrieve the discriminants from the entity
10859 rather than from the type definition, because in the case of a full
10860 type for a private type we need to take the discriminants from the
10862 (Layout_Component_List): When applying the Max operator to variants with
10863 a nonstatic size, check whether either operand is static and scale that
10864 operand from bits to storage units before applying Max.
10865 (Layout_Type): In VMS, if a C-convention access type has no explicit
10866 size clause (and does not inherit one in the case of a derived type),
10867 then the size is reset to 32 from 64.
10869 2006-10-31 Vincent Celier <celier@adacore.com>
10871 * lib-load.adb (Load_Unit): Skip the test for a unit not found when
10872 its file has already been loaded, according to the unit being loaded,
10873 not to the current value of Multiple_Unit_Index.
10875 2006-10-31 Thomas Quinot <quinot@adacore.com>
10876 Eric Botcazou <ebotcazou@adacore.com>
10877 Arnaud Charlet <charlet@adacore.com>
10879 * Makefile.in: Set EH mechanism to ZCX for FreeBSD.
10880 (NO_REORDER_ADAFLAGS): New var defined to -fno-toplevel-reorder if
10882 (a-except.o): Pass it to the compiler.
10883 (gnatlib-shared-vms): Removed -nostartfiles switch in link step.
10884 (LIBGNAT_TARGET_PAIRS for Windows): Avoid the use of the specific
10885 a-calend-mingw.adb version.
10887 * Makefile.rtl: Added s-dsaser.
10888 Add object entries for Ada.Calendar.[Arithmetic/Formatting/Time_Zones]
10889 (GNATRTL_TASKING_OBJS): Add Ada.Dispatching and
10890 Ada.Dispatching.Round_Robin.
10891 Added new unit Ada.Containers.Restricted_Bounded_Doubly_Linked_Lists
10893 * Make-lang.in: Remove all references to gt-ada-decl.h.
10894 Add concatenation (s-strops/s-sopco3/s-sopco4/s-sopco5) to compiler
10896 Add dependency on ada/s-restri.o for GNAT1 and GNATBIND objects.
10897 Update dependencies.
10899 * system-freebsd-x86.ads: Make ZCX the default EH mechanism for FreeBSD
10901 2006-10-31 Vincent Celier <celier@adacore.com>
10903 * mlib-utl.adb (Initialized): Remove, no longer used
10904 (Initialize): Remove, no longer used
10905 (Ar): If Ar_Exec is null, get the location of the archive builder and,
10906 if there is one, the archive indexer. Fail if the archive builder cannot
10908 (Gcc): If the driver path is unknown, get it. Fail if the driver cannot
10911 2006-10-31 Ed Schonberg <schonberg@adacore.com>
10913 * sem_ch10.ads, sem_ch10.adb (Check_Redundant_Withs,
10914 Process_Body_Clauses): If the context of a body includes a use clause
10915 for P.Q then a with_clause for P in the same body is not redundant,
10916 even if the spec also has a with_clause on P.
10917 Add missing continuation mark to error msg
10918 (Build_Limited_Views): A limited view of a type is tagged if its
10919 declaration includes a record extension.
10920 (Analyze_Proper_Body): Set Corresponding_Stub field in N_Subunit
10921 node, even if the subunit has errors. This avoids malfunction by
10922 Lib.Check_Same_Extended_Unit in the presence of syntax errors.
10923 (Analyze_Compilation_Unit): Add circuit to make sure we get proper
10924 generation of obsolescent messages for with statements (cannot do
10925 this too early, or we cannot implement avoiding the messages in the
10926 case of obsolescent units withing obsolescent units).
10927 (Install_Siblings): If the with_clause is on a remote descendant of
10928 an ancestor of the current compilation unit, find whether there is
10929 a sibling child unit that is immediately visible.
10930 (Remove_Private_With_Clauses): New procedure, invoked after completing
10931 the analysis of the private part of a nested package, to remove from
10932 visibility the private with_clauses of the enclosing package
10934 (Analyze_With_Clause): Remove Check_Obsolescent call, this checking is
10935 now centralized in Generate_Reference.
10936 (Install_Limited_Context_Clauses): Remove superfluous error
10937 message associated with unlimited view visible through use
10938 and renamings. In addition, at the point in which the error
10939 is reported, we add the backslash to the text of the error
10940 to ensure that it is reported as a single error message.
10941 Use new // insertion for some continuation messages
10942 (Expand_Limited_With_Clause): Use copy of name rather than name itself,
10943 to create implicit with_clause for parent unit mentioned in original
10944 limited_with_clause.
10945 (Install_Limited_With_Unit): Set entity of parent identifiers if the
10946 unit is a child unit. For ASIS queries.
10947 (Analyze_Subunit): If the subunit appears within a child unit, make all
10948 ancestor child units directly visible again.

10963 a formal object declaration with an access definition or a subtype mark
10964 with a null exclusion.
10965 (P_Generic_Association): Handle association with box, and others_choice
10966 with box, to support Ada 2005 partially parametrized formal packages.
10968 2006-10-31 Robert Dewar <dewar@adacore.com>
10969 Javier Miranda <miranda@adacore.com>
10971 * par-ch3.adb (P_Range_Or_Subtype_Mark): Check for bad parentheses
10972 (P_Type_Declaration): Remove barrier against the reserved word "limited"
10973 after "abstract" to give support to the new syntax of AARM 3.4 (2/2).

10975 private extensions.
10976 (P_Type_Declaration): Add the new actual Abstract_Present to every call

11009 of sources, even if it is not the first time, as it is for another
11011 (Get_Unit): Replace both '_' (after 'a', 'g', 'i' or 's') with a single
11012 dot, instead of replacing only the first '_'.
11014 * prj-part.adb (Parse): Convert project file path to canonical form
11016 * prj-proc.adb (Recursive_Process): Make sure that, when a project is
11017 extended, the project id of the project extending it is recorded in its

11026 Robert Dewar <dewar@adacore.com>
11028 * restrict.ads, restrict.adb (Restriction_Active): Now returns False if
11029 only a restriction warning is active for the given restriction. This is
11030 desirable because we do not want to modify code in the case where only
11032 (Set_Profile_Restrictions): Make sure that a Profile_Warnings never
11033 causes overriding of real restrictions.
11034 Take advantage of new No_Restrictions constant.
11036 * raise.h: (__gnat_set_globals): Change profile.
11038 2006-10-31 Arnaud Charlet <charlet@adacore.com>
11040 * rtsfind.adb: Remove s-polint from comment as it exists no more.
11043 Move entity RE_Get_Active_Partition_Id to package System.DSA_Services.
11044 Move all the entities in obsolete package System.PolyORB_Interface to
11045 System.Partition_Interface.

11063 * sem_attr.ads, sem_attr.adb (Analyze_Access_Attribute): Diagnose
11064 properly an attempt to apply Unchecked_Access to a protected operation.
11065 (OK_Self_Reference): New subprogram to check the legality of an access
11066 attribute whose prefix is the type of an enclosing aggregate.
11067 Generalizes previous mechanism to handle attribute references nested
11068 arbitrarily deep within the aggregate.
11069 (Analyze_Access_Attribute): An access attribute whose prefix is a type
11070 can appear in an aggregate if this is a default-initialized aggregate
11071 for a self-referential type.
11072 (Resolve_Attribute, case Access): Ditto.
11073 Add support for new implementation defined attribute Stub_Type.
11074 (Eval_Attribute, case Attribute_Stub_Type): New case.
11075 (Analyze_Attribute, case Attribute_Stub_Type): New case.
11076 (Stream_Attribute_Available): Implement using new subprogram from
11077 sem_cat, Has_Stream_Attribute_Definition, instead of incorrect
11078 Has_Specified_Stream_Attribute flag.
11079 Disallow Storage_Size and Storage_Pool for access to subprogram
11080 (Resolve_Attribute, case 'Access et al): Take into account anonymous
11081 access types of return subtypes in extended return statements. Remove
11082 accessibility checks on anonymous access types when Unchecked_Access is
11084 (Analyze_Attribute): Add support for the use of 'Class to convert
11085 a class-wide interface to a tagged type.
11086 Add support for the attribute Priority.
11087 (Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
11088 whether the designated type is discriminated with a constrained partial
11089 view and require static matching in that case.
11090 Add local variable Des_Btyp. The Designated_Type
11091 of an access to incomplete subtype is either its non-limited view if
11092 coming from a limited with or its etype if regular incomplete subtype.
11094 * sem_cat.ads, sem_cat.adb (Validate_Remote_Access_To_Class_Wide_Type):
11095 Fix predicate to identify and allow cases of (expander-generated)
11096 references to tag of designated object of a RACW.
11097 (Validate_Static_Object_Name): In Ada 2005, a formal object is
11098 non-static, and therefore cannot appear as a primary in a preelaborable
11100 (Has_Stream_Attribute_Definition): New subprogram, abstracted from
11101 Has_Read_Write_Attributes.
11102 (Has_Read_Write_Attributes): Reimplement in termes of
11103 Has_Stream_Attribute_Definition.
11104 (Missing_Read_Write_Attributes): When checking component types in a
11105 record, unconditionally call Missing_Read_Write_Attributes recursively
11106 (remove guard checking for Is_Record_Type / Is_Access_Type).
11108 2006-10-31 Robert Dewar <dewar@adacore.com>
11110 * sem_ch11.adb (Analyze_Handled_Statements): Move final test for
11111 useless assignments here and conditionalize it on absence of exception
11113 (Analyze_Exception_Handlers): Small code reorganization of error
11114 detection code, for new handling of formal packages.
11116 2006-10-31 Ed Schonberg <schonberg@adacore.com>
11117 Hristian Kirtchev <kirtchev@adacore.com>
11119 * sem_ch12.ads, sem_ch12.adb (Save_References): If node is an operator
11120 that has been constant-folded, preserve information of original tree,
11122 (Analyze_Formal_Derived_Type): Set the limited present flag of the newly
11123 generated private extension declaration if the formal derived type is
11124 synchronized. Carry synchronized present over to the generated private
11126 (Validate_Derived_Type_Instance): Ensure that the actual of a
11127 synchronized formal derived type is a synchronized tagged type.
11128 (Instantiate_Formal_Package): When creating the instantiation used to
11129 validate the actual package of a formal declared without a box, check
11130 whether the formal itself depends on a prior actual.
11131 (Instantiate_Formal_Subprogram): Create new entities for the defining
11132 identifiers of the formals in the renaming declaration, for ASIS use.
11133 (Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
11134 a renaming declaration or a subtype declaration for an actual in an
11135 instance, capture location information of declaration in generic, for
11137 (Instantiate_Formal_Package): Add comments on needed additional tests.
11138 AI-317 (partial parametrization) is fully implemented.
11139 (Validate_Private_Type_Instance): Add check for actual which
11140 must have preelaborable initialization
11141 Use new // insertion for some continuation messages
11142 (Analyze_Formal_Object_Declaration): Change usage of Expression to
11143 Default_Expression. Add type retrieval when the declaration has an
11144 access definition. Update premature usage of incomplete type check.
11145 (Check_Access_Definition): New subsidiary routine. Check whether the
11146 current compilation version is Ada 05 and the supplied node has an
11148 (Instantiate object): Alphabetize local variables. Handle the creation
11149 of new renaming declarations with respect to the kind of definition
11150 used - either an access definition or a subtype mark. Guard against
11151 unnecessary error message in the context of anonymous access types after
11152 they have been resolved. Add check for required null exclusion in a
11153 formal object declaration.
11154 (Switch_View): A private subtype of a non-private type needs to be
11155 switched (the base type can have been switched without its private
11156 dependents because of the last branch of Check_Private_View.
11157 (Check_Private_View): Do not recompute Base_Type (T), instead use cached
11159 (Instantiate_Type): Emit an error message whenever a class-wide type of
11160 a tagged incomplete type is used as a generic actual.
11161 (Find_Actual_Type): Extend routine to handle a component type in a child
11162 unit that is imported from a formal package in a parent.
11163 (Validate_Derived_Type_Instance): Check that analyzed formal and actual
11164 agree on constrainedness, rather than checking against ultimate ancestor
11165 (Instantiate_Subprogram_Body): Create a cross-reference link to the
11166 generic body, for navigation purposes.

11169 Thomas Quinot <quinot@adacore.com>
11171 * sem_ch13.adb: Storage pool cannot be given for access to subprogram
11173 (New_Stream_Subprogram): When processing an attribute definition clause
11174 for a stream-oriented subprogram, record an entity node occurring at
11175 the point of clause to use for checking the visibility of the clause,
11176 as defined by 8.3(23) as amended by AI-195.
11177 (New_Stream_Subprogram): New procedure, factoring behaviour from both
11178 New_Stream_Function and New_Stream_Procedure.
11179 (New_Stream_Function, New_Stream_Procedure): Removed.
11180 (Analyze_Attribute_Definition_Clause, case Address): Check new
11181 Alignment_Check check

11184 Javier Miranda <miranda@adacore.com>
11185 Robert Dewar <dewar@adacore.com>
11187 * sem_ch4.adb (Try_Primitive_Operation): Code cleanup to ensure that we
11188 generate the same errors compiling under -gnatc.
11189 (Try_Object_Operation): If no candidate interpretation succeeds, but
11190 there is at least one primitive operation with the right name, report
11191 error in call rather than on a malformed selected component.
11192 (Analyze_Selected_Component): If the prefix is an incomplete type from
11193 a limited view, and the full view is available, use the full view to
11194 determine whether this is a prefixed call to a primitive operation.
11195 (Operator_Check): Verify that a candidate interpretation is a binary
11196 operation before checking the type of its second formal.
11197 (Analyze_Call): Add additional warnings for function call contexts not
11199 (Analyze_Allocator): Move the check for "initialization not allowed for
11200 limited types" after analyzing the expression. This is necessary,
11201 because OK_For_Limited_Init looks at the structure of the expression.
11202 Before analysis, we don't necessarily know what sort of expression it
11203 is. For example, we don't know whether F(X) is a function call or an
11204 indexed component; the former is legal in Ada 2005; the latter is not.
11205 (Analyze_Allocator): Correct code for AI-287 -- extension aggregates
11206 were missing. We also didn't handle qualified expressions. Now also
11207 allow function calls. Use new common routine OK_For_Limited_Init.
11208 (Analyze_Type_Conversion): Do not perform some legality checks in an
11209 instance, because the error message will be redundant or spurious.
11210 (Analyze_Overloaded_Selected_Component): Do not do style check when
11211 setting an entity, since we do not know it is the right entity yet.
11212 (Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
11213 (Analyze_Overloaded_Selected_Component): Same change
11214 (Analyze_Selected_Component): Remove unnecessary prefix type retrieval
11215 since regular incomplete subtypes are transformed into corresponding
11216 subtypes of their full views.
11217 (Complete_Object_Operation): Treat name of transformed subprogram call
11218 as coming from source, for browsing purposes.
11219 (Try_Primitive_Operation): If formal is an access parameter, compare
11220 with base type of object to determine whether it is a primitive
11222 (Operator_Check): If no interpretation of the operator matches, check
11223 whether a use clause on any candidate might make the operation legal.
11224 (Try_Class_Wide_Operation): Check whether the first parameter is an
11225 access type whose designated type is class-wide.

11232 warn on infinite loops.
11233 Add \\ to some continuation messages
11234 (Analyze_Assignment_Statement): Call Warn_On_Useless_Assignment
11235 (Process_Bounds): If the bounds are integer literals that result from
11236 constant-folding, and they carry a user-defined type, preserve that type
11237 rather than treating this as an integer range.
11238 (Analyze_Exit_Statement): Test for E_Return_Statement in legality check.
11239 (Analyze_Goto_Statement): Test for E_Return_Stateemnt in legality check.
11240 (Analyze_Assignment_Statement): Add call to Check_Elab_Assign for
11241 left hand side of assignment.
11242 (Analyze_Assignment): Add suport to manage assigments to the attribute
11243 priority of a protected object.
11244 (Check_Possible_Current_Value_Condition): Allow fully qualified names
11245 not just identifiers.
11246 (Check_Possible_Current_Value_Condition): Acquire left operand of AND
11247 or AND THEN for possible tracking.
11248 (Analyze_Iteration_Scheme): Check for setting Current_Value for the
11249 case of while loops so we can track values in the loop body.
11251 2006-10-31 Ed Schonberg <schonberg@adacore.com>
11252 Hristian Kirtchev <kirtchev@adacore.com>
11253 Bob Duff <duff@adacore.com>
11255 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
11256 procedure cannot be a protected operation (it is a basic_declaration,
11257 not a subprogram_declaration).
11258 (Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
11259 Subp. Add logic for entry processing.
11260 (Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.
11261 Determine whether an entry or subprogram of a protected or task type
11262 override an inherited primitive of an implemented interface.
11263 (New_Overloaded_Entity): Add calls to Check_Synchronized_Overriding.
11264 Update the actual used in calls to Check_Overriding_Indicator.
11265 (Analyze_Generic_Subprogram_Body): If the subprogram is a child unit,
11266 generate the proper reference to the parent unit, for cross-reference.
11267 (Analyze_Subprogram_Declaration): Protect Is_Controlling_Formal with
11269 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
11270 (Add_Extra_Formal): Revise procedure to allow passing in associated
11271 entity, scope, and name suffix, and handle setting of the new
11272 Extra_Formals field.
11273 (Create_Extra_Formals): Change existing calls to Add_Extra_Formal to
11274 pass new parameters. Add support for adding the new extra access formal
11275 for functions whose calls are treated as build-in-place.
11276 (Analyze_A_Return_Statement): Correct casing in error message.
11277 Move Pop_Scope to after Analyze_Function_Return, because an extended
11278 return statement really is a full-fledged scope. Otherwise, visibility
11279 doesn't work right. Correct use of "\" for continuation messages.
11280 (Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
11281 evilly trying to call Analyze_Object_Declaration directly. Otherwise,
11282 the node doesn't get properly marked as analyzed.
11283 (Analyze_Subprogram_Body): If subprogram is a function that returns
11284 an anonymous access type that denotes a task, build a Master Entity
11286 (Analyze_Return_Type): Add call to Null_Exclusion_Static_Checks. Verify
11287 proper usage of null exclusion in a result definition.
11288 (Process_Formals): Code cleanup and new error message.
11289 (Process_Formals): Detect incorrect application of null exclusion to
11291 (Conforming_Types): Handle conformance between [sub]types and itypes
11292 generated for entities that have null exclusions applied to them.
11293 (Maybe_Primitive_Operation): Add an additional type retrieval when the
11294 base type is an access subtype. This case arrises with null exclusions.
11295 (New_Overloaded_Entity): Do not remove the overriden entity from the
11296 homonym chain if it corresponds with an abstract interface primitive.
11297 (Process_Formals): Replace membership test agains Incomplete_Kind with a
11298 call to the synthesized predicate Is_Incomplete_Type.
11299 (Analyze_Subprogram_Body): Check wrong placement of abstract interface
11301 (Analyze_Subprogram_Declaration): Check that abstract interface
11302 primitives are abstract or null.
11303 (Analyze_Subprogram_Specification): Remove previous check for abstract
11304 interfaces because it was not complete.
11305 (Has_Interface_Formals): Removed.
11307 2006-10-31 Ed Schonberg <schonberg@adacore.com>
11308 Javier Miranda <miranda@adacore.com>
11310 * sem_ch7.adb (Check_Anonymous_Access_Types): New procedure, subsidiary
11311 of Analyze_Package_Body, to create Itype references for anonymous
11312 access types created in the package declaration, whose designated types
11313 may have only a limited view.
11314 (Analyze_Package_Specification): For the private part of a nested
11315 package, install private_with_clauses of enclosing compilation unit if
11316 we are in its visible part.
11317 (Declare_Inherited_Private_Subprograms): Complete barrier
11318 to ensure that the primitive operation has an alias to some parent
11319 primitive. This is now required because, after the changes done for the
11320 implementation of abstract interfaces, the contents of the list of
11321 primitives has entities whose alias attribute references entities of
11322 such list of primitives.
11323 (Analyze_Package_Specification): Simplify code that handles parent units
11324 of instances and formal packages.
11325 (Uninstall_Declarations): Check the convention consistency among
11326 primitive overriding operations of a tagged record type.

11335 expected and found set right)
11336 (Analyze_Subprogram_Renaming): Propagate Is_Pure, Is_Preelaborated
11337 (Analyze_Generic_Renaming): Same fix
11338 (Use_One_Package): Do not take into account the internal entities of
11339 abstract interfaces during the analysis of entities that are marked
11340 as potentially use-visible.
11341 (Find_Type): Handle the case of an attribute reference for
11342 implementation defined attribute Stub_Type (simply let the analysis of
11343 the attribute reference rewrite it).
11344 (Use_One_Type, End_Use_Type): Reject a reference to a limited view of a
11345 type that appears in a Use_Type clause.
11346 (Analyze_Object_Renaming): Add support for renaming of the Priority
11348 (Find_Type): In Ada 2005, a task type can be used within its own body,
11349 when it appears in an access definition.
11350 (Analyze_Object_Renaming): Remove warning on null_exclusion.
11351 (Analyze_Object_Renaming): Introduce checks for required null exclusion
11352 in a formal object declaration or in a subtype declaration.
11353 (Analyze_Subprogram_Renaming): Add call to Check_Null_Exclusion.
11354 (Check_Null_Exclusion): New local routine to
11355 Analyze_Subprogram_Renaming. Check whether the formals and return
11356 profile of a renamed subprogram have required null exclusions when
11357 their counterparts of the renaming already impose them.
11358 (In_Generic_Scope): New local routine to Analyze_Object_Renaming.
11359 Determine whether an entity is inside a generic scope.
11360 (In_Open_Scope): First pass of documentation update.
11361 (Find_Expanded_Name): Add support for shadow entities associated with
11362 limited withed packages. This is required to handle nested packages.
11363 (Analyze_Package_Renaming): Remove the restriction imposed by AI-217
11364 that makes a renaming of a limited withed package illegal.

11370 Check_Overriding_Indicator.
11371 (Analyze_Task_Definition): Ditto.
11372 (Analyze_Protected_Type, Analyze_Task_Type): Code cleanup.
11373 (Check_Overriding_Indicator): To find overridden interface operation,
11374 examine only homonyms that have an explicit subprogram declaration, not
11375 inherited operations created by an unrelated type derivation.
11376 (Check_Overriding_Indicator): When checking for the presence of "null"
11377 in a procedure, ensure that the queried node is a procedure
11379 (Matches_Prefixed_View_Profile): Add mechanism to retrieve the parameter
11380 type when the formal is an access to variable.
11381 (Analyze_Protected_Type): Add check for Preelaborable_Initialization
11382 (Analyze_Task_Type): Same addition
11383 (Analyze_Entry_Declaration): Call Generate_Reference_To_Formals, to

11398 secondary dispatch tables associated with abstract interfaces.
11399 (Check_Dispatching_Call): Add check that a dispatching call is not made

11451 ought to be used, but we currently only deal properly with zero or one
11453 (In_Instance); The analysis of the actuals in the instantiation of a
11454 child unit is not within an instantiation, even though the parent

11717 object, to provide mutual exclusion to the queue of pending events
11718 and the type Timing_Event is no longer a protected type.

12225 evaluate the conversion at run-time.

12836 Make message unconditional if it is a warning.
12837 (Error_Msg_NEL): Always output warning messages.
12838 Suppress range checks for a couple of assignments which otherwise
12839 cause validity checks with validity checking turned on.

12842 implied by '?' in error messages.
12844 * gnat1drv.adb: (Bad_Body): Remove '!' in warning message.
12845 (Gnat1drv): Use a goto to end of main subprogram instead of
12846 Exit_Program (E_Success) so that finalization can occur normally.
12848 2006-02-13 Eric Botcazou <ebotcazou@adacore.com>
12850 * s-stchop.adb (Stack_Check): Raise Storage_Error if the argument has

12864 Thomas Quinot <quinot@adacore.com>
12866 * checks.adb (Build_Discriminant_Checks): If the expression being
12867 checks is an aggregate retrieve the values of its discriminants to
12868 generate the check, rather than creating a temporary and a reference
12870 (Apply_Access_Check): Rewritten to handle new Is_Known_Null flag
12871 (Install_Null_Excluding_Check): Ditto
12872 (Selected_Length_Checks): Build actual subtype for the original Ck_Node,

12885 error message with the full switch.
12886 Eliminate numeric switches for binder/gnatmake
12888 * switch.ads, switch.adb (Bad_Switch): New procedure
12890 * switch-b.adb (Scan_Binder_Switches): Do not accept combined switches.
12891 Remove 0-9 as debug flag character possibilities
12892 -d is now controlling the primary stack size when its value is a
12893 positive. Also add checks against invalid values, and support for kb,
12894 mb. Ditto for -D switch.
12896 2006-02-13 Robert Dewar <dewar@adacore.com>
12897 Serguei Rybin <rybin@adacore.com>
12899 * opt.ads opt.adb: Add Ada_Version_Explicit_Config along with
12900 save/restore routines.
12901 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
12902 were not always properly handled previously.
12903 Since we are changing the tree format anyway, also get rid of the
12904 junk obsolete Immediate_Errors flag.
12905 (Tree_Read): Change the way of reading Tree_Version_String - now we
12906 read the version string from the tree even if its length is not the
12907 same as the length of the version string computed from Gnatvsn.
12908 (Search_Directory_Present): New Boolean flag for the compiler.
12909 Define Tree_Version_String as a dynamic string.
12910 (Default_Stack_Size): new variable, used to handle switch -d.
12913 For pragma Ada_2005, remove stuff about setting Ada_Version_Explicit
12914 only for main unit.
12915 Add pragma Ada_2005 (synonym for Ada_05)
12916 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
12917 were not always properly handled previously.
12919 * directio.ads, ioexcept.ads, sequenio.ads, text_io.ads: Change
12920 explicit Ada_95 to Ada_2005.
12922 2006-02-13 Javier Miranda <miranda@adacore.com>
12923 Robert Dewar <dewar@adacore.com>
12924 Ed Schonberg <schonberg@adacore.com>
12926 * einfo.ads, einfo.adb (First_Tag_Component): Protect the frontend
12927 against errors in the source program: a private types for which the
12928 corresponding full type declaration is missing and pragma CPP_Virtual
12930 (Is_Unchecked_Union): Check flag on Implementation_Base_Type.
12931 (Is_Known_Null): New flag
12932 (Has_Pragma_Pure): New flag
12933 (No_Return): Present in all entities, set only for procedures
12934 (Is_Limited_Type): A type whose ancestor is an interface is limited if
12935 explicitly declared limited.
12936 (DT_Offset_To_Top_Func): New attribute that is present in E_Component
12937 entities. Only used for component marked Is_Tag. If present it stores
12938 the Offset_To_Top function used to provide this value in tagged types
12939 whose ancestor has discriminants.
12941 * exp_ch2.adb: Update status of new Is_Known_Null flag
12943 * sem_ch7.adb: Maintain status of new Is_Known_Null flag
12945 * sem_cat.adb (Get_Categorization): Don't treat function as Pure in
12946 the categorization sense if Is_Pure was set by pragma Pure_Function.
12948 2006-02-13 Quentin Ochem <ochem@adacore.com>
12949 Olivier Hainque <hainque@adacore.com>
12951 * bindusg.adb: Updated documentation for -d and -D switches.
12953 * raise.h (__gnat_set_globals): added new parameter for
12954 Default_Stack_Size.
12956 * init.c (__gnat_adjust_context_for_raise) <alpha-vms case>: Implement.
12957 (__gnat_handle_vms_condition): Adjust context before raise.
12958 (__gnat_install_handler): Restore the global vector setup for GCC
12959 versions before 3.4, as the frame based circtuitry is not available
12961 (__gnat_set_globals): added a parameter default_stack_size
12962 (__gl_default_stack_size): new variable.
12964 2006-02-13 Ed Schonberg <schonberg@adacore.com>
12966 * exp_aggr.adb (Build_Array_Aggr_Code): Rename variable
12967 "Others_Mbox_Present" to "Others_Box_Present" because the mbox concept
12968 does not exist in the Ada RM.
12969 (Compatible_Int_Bounds): Determine whether two integer range bounds
12970 are of equal length and have the same start and end values.
12971 (Is_Int_Range_Bounds): Determine whether a node is an integer range.
12972 (Build_Record_Aggr_Code): Perform proper sliding of a nested array
12973 aggregate when it is part of an object declaration.
12974 (Build_Record_Aggr_Code) If the aggregate ttype is a derived type that
12975 constrains discriminants of its parent, add explicitly the discriminant
12976 constraints of the ancestor by retrieving them from the
12977 stored_constraint of the parent.
12979 2006-02-13 Robert Dewar <dewar@adacore.com>
12981 * exp_attr.adb (Expand_N_Attribute_Reference, case Mechanism_Code): If
12982 attribute Mechanism_Code is applied to renamed subprogram, modify
12983 prefix to point to base subprogram.
12984 Max/Min attributes now violate Restriction No_Implicit_Conditionals
12986 * sinfo.ads: Document that Mechanism_Code cannot be applied to
12987 renamed subprograms so that the front-end must replace the prefix
12990 2006-02-13 Javier Miranda <miranda@adacore.com>
12991 Gary Dismukes <dismukes@adacore.com>
12993 * exp_ch3.adb (Component_Needs_Simple_Initialization): Add check for
12994 availability of RE_Interface_Tag.
12995 (Build_Initialization_Call): Fix wrong access to the discriminant value.
12996 (Freeze_Record_Type): Do not generate the tables associated with
12997 timed and conditional dispatching calls through synchronized
12998 interfaces if compiling under No_Dispatching_Calls restriction.
12999 When compiling for Ada 2005, for a nonabstract
13000 type with a null extension, call Make_Controlling_Function_Wrappers
13001 and insert the wrapper function declarations and bodies (the latter
13002 being appended as freeze actions).
13003 (Predefined_Primitive_Bodies): Do not generate the bodies of the
13004 predefined primitives associated with timed and conditional
13005 dispatching calls through synchronized interfaces if we are
13006 compiling under No_Dispatching_Calls.
13007 (Build_Init_Procedure): Use RTE_Available to check if a run-time
13008 service is available before generating a call.
13009 (Make_Controlling_Function_Wrappers): New procedure.
13010 (Expand_N_Full_Type_Declaration): Create a class-wide master for
13011 access-to-limited-interfaces because they can be used to reference
13012 tasks that implement such limited interface.
13013 (Build_Offset_To_Top_Functions): Build the tree corresponding to the
13014 procedure spec and body of the Offset_To_Top function that is generated
13015 when the parent of a type with discriminants has secondary dispatch
13017 (Init_Secondary_Tags): Handle the case in which the parent of the type
13018 containing secondary dispatch tables has discriminants to generate the
13019 correct arguments to call Set_Offset_To_Top.
13020 (Build_Record_Init_Proc): Add call to Build_Offset_To_Top_Functions.
13022 * a-tags.ads, a-tags.adb: (Check_Index): Removed.
13023 Add Wide_[Wide_]Expanded_Name.
13024 (Get_Predefined_Prim_Op_Address): New subprogram that provides exactly
13025 the same functionality of Get_Prim_Op_Address but applied to predefined
13026 primitive operations because the pointers to the predefined primitives
13027 are now saved in a separate table.
13028 (Parent_Size): Modified to get access to the separate table of primitive
13029 operations or the parent type.
13030 (Set_Predefined_Prim_Op_Address): New subprogram that provides the same
13031 functionality of Set_Prim_Op_Address but applied to predefined primitive
13033 (Set_Signature): New subprogram used to store the signature of a DT.
13034 (Displace): If the Offset_To_Top value is not static then call the
13035 function generated by the expander to get such value; otherwise use
13036 the value stored in the table of interfaces.
13037 (Offset_To_Top): The type of the actual has been changed to Address to
13038 give the correct support to tagged types with discriminants. In this
13039 case this value is stored just immediately after the tag field.
13040 (Set_Offset_To_Top): Two new formals have been added to indicate if the
13041 offset_to_top value is static and hence pass this value to the run-time
13042 to store it in the table of interfaces, or else if this value is dynamic
13043 and then pass to the run-time the address of a function that is
13044 generated by the expander to provide this value for each object of the
13047 * rtsfind.ads (Default_Prin_Op_Count): Removed.
13048 (Default_Prim_Op_Count): New entity
13049 (Get_Predefined_Prim_Op_Address): New entity
13050 (Set_Predefined_Prim_Op_Address): New entity

13054 Ed Schonberg <schonberg@adacore.com>
13056 * exp_ch4.adb (Expand_Allocator_Expression): Pass Allocator => True to
13057 Make_Adjust_Call done for a newly-allocated object.
13059 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): If the statements
13060 in a subprogram are wrapped in a cleanup block, indicate that the
13061 subprogram contains an inner block with an exception handler.
13062 (Make_Adjust_Call): New Boolean formal Allocator indicating whether the
13063 Adjust call is for a newly-allocated object. In that case we must not
13064 assume that the finalization list chain pointers are correct (since they
13065 come from a bit-for-bit copy of the original object's pointers) so if
13066 the attach level would otherwise be zero (no change), we set it to 4
13067 instead to cause the pointers to be reset to null.
13069 * s-finimp.adb (Attach_To_Final_List): New attach level: 4, meaning
13070 reset chain pointers to null.
13072 2006-02-13 Ed Schonberg <schonberg@adacore.com>
13074 * exp_ch5.adb (Expand_Assign_Array): If the right-hand side is a
13075 string, and the context requires a loop for the assignment (e.g.
13076 because the left-hand side is packed), generate a unique name for the
13077 temporary that holds the string, to prevent spurious name clashes.
13079 2006-02-13 Ed Schonberg <schonberg@adacore.com>
13080 Javier Miranda <miranda@adacore.com>
13081 Robert Dewar <dewar@adacore.com>
13082 Gary Dismukes <dismukes@adacore.com>
13084 * exp_ch6.adb (Expand_Inlined_Call): Handle calls to functions that
13085 return unconstrained arrays.
13087 (Expand_Call): An indirect call through an access parameter of a
13088 protected operation is not a protected call.
13089 Add circuit to raise CE in Ada 2005 mode following call
13090 to Raise_Exception.
13091 (Register_DT_Entry): Do nothing if
13092 the run-time does not give support to abstract interfaces.
13093 (Freeze_Subprogram): In case of dispatching operations, do not generate
13094 code to register the operation in the dispatch table if the source
13095 is compiled with No_Dispatching_Calls.
13096 (Register_Predefined_DT_Entry): Generate code that calls the new
13097 run-time subprogram Set_Predefined_Prim_Op_Address instead of
13098 Set_Prim_Op_Address.
13100 * sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length checks
13101 on array assignments if the right-hand side is a function call that has
13102 been inlined. Check is performed on the assignment in the block.
13103 (Process_Bounds): If bounds and range are overloaded, apply preference
13104 rule for root operations to disambiguate, and diagnose true ambiguity.
13105 (Analyze_Assignment): Propagate the tag for a class-wide assignment with
13106 a tag-indeterminate right-hand side even when Expander_Active is True.
13107 Needed to ensure that dispatching calls to T'Input are allowed and
13108 get the tag of the target class-wide object.
13110 * sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
13111 an inherited primitive operation that already overrides several
13112 abstract interface primitives. For transitivity, the new entity must
13113 also override all the abstract interface primitives covered by the
13114 inherited overriden primitive.
13115 Emit warning if new entity differs from homograph in same scope only in
13116 that one has an access parameter and the other one has a parameter of
13117 a general access type with the same designated type, at the same
13118 position in the signature.
13119 (Make_Inequality_Operator): Use source locations of parameters and
13120 subtype marks from corresponding equality operator when creating the
13121 tree structure for the implicit declaration of "/=". This does not
13122 change anything in behaviour except that the decoration of the
13123 components of the subtree created for "/=" allows ASIS to get the
13124 string images of the corresponding identifiers.
13125 (Analyze_Return_Statement): Remove '!' in warning message.
13126 (Check_Statement_Sequence): Likewise.
13127 (Analyze_Subprogram_Body): For an access parameter whose designated type
13128 is an incomplete type imported through a limited_with clause, use the
13129 type of the corresponding formal in the body.
13130 (Check_Returns): Implicit return in No_Return procedure now raises
13131 Program_Error with a compile time warning, instead of beging illegal.
13132 (Has_Single_Return): Function returning unconstrained type cannot be
13133 inlined if expression in unique return statement is not an identifier.
13134 (Build_Body_To_Inline): It is possible to inline a function call that
13135 returns an unconstrained type if all return statements in the function
13136 return the same local variable. Subsidiary procedure Has_Single_Return
13137 verifies that the body conforms to this restriction.
13139 * sem_res.adb (Resolve_Equality_Op): If the operands do not have the
13140 same type, and one of them is of an anonymous access type, convert
13141 the other operand to it, so that this is a valid binary operation for
13143 (Resolve_Type_Conversion): Handle subtypes of protected types and
13144 task types when accessing to the corresponding record type.
13145 (Resolve_Allocator): Add '\' in 2-line warning message.
13146 Remove '!' in warning message.
13147 (Resolve_Call): Add '\' in 2-line warning message.
13148 (Valid_Conversion): Likewise.
13149 (Resolve_Overloaded_Selected_Component): If disambiguation succeeds, the
13150 resulting type may be an access type with an implicit dereference.
13151 Obtain the proper component from the designated type.
13152 (Make_Call_Into_Operator): Handle properly a call to predefined equality
13153 given by an expanded name with prefix Standard, when the operands are
13154 of an anonymous access type.
13155 (Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
13156 Explicit_Dereference and Resolve_Selected_Component, to verify that the
13157 prefix of the expression is not of an incomplete type. Allows full
13158 diagnoses of all semantic errors.
13159 (Resolve_Actuals): If the actual is an allocator whose directly
13160 designated type is a class-wide interface we build an anonymous
13161 access type to use it as the type of the allocator. Later, when
13162 the subprogram call is expanded, if the interface has a secondary
13163 dispatch table the expander will add a type conversion to force
13164 the displacement of the pointer.
13165 (Resolve_Call): If a function that returns an unconstrained type is
13166 marked Inlined_Always and inlined, the call will be inlined and does
13167 not require the creation of a transient scope.
13168 (Check_Direct_Boolean_Op): Removed
13169 (Resolve_Comparison_Op): Remove call to above
13170 (Resolve_Equality_Op): Remove call to above
13171 (Resolve_Logical_Op): Inline above, since this is only call.
13172 (Valid_Conversion): Handle properly conversions between arrays of
13173 convertible anonymous access types.
13176 (Set_Literal_String_Subtype): If the lower bound is not static, wrap
13177 the literal in an unchecked conversion, because GCC 4.x needs a static
13178 value for a string bound.
13180 2006-02-13 Ed Schonberg <schonberg@adacore.com>
13181 Hristian Kirtchev <kirtchev@adacore.com>
13183 * exp_ch9.adb (Expand_N_Protected_Type_Declaration): When creating the
13184 components of the corresponding record, take into account component
13185 definitions that are access definitions.
13186 (Expand_N_Asynchronous_Select): A delay unit statement rewritten as a
13187 procedure is not considered a dispatching call and will be expanded
13190 2006-02-13 Javier Miranda <miranda@adacore.com>
13192 * exp_disp.ads, exp_disp.adb (Expand_Dispatching_Call): If the
13193 controlling argument of the dispatching call is an abstract interface
13194 class-wide type then we use it directly.
13195 Check No_Dispatching_Calls restriction.
13196 (Default_Prim_Op_Position): Remove the code that looks for the last
13197 entity in the list of aliased subprograms. This code was wrong in
13199 (Fill_DT_Entry): Add assertion to avoid the use of this subprogram
13200 when the source is compiled with the No_Dispatching_Calls restriction.
13201 (Init_Predefined_Interface_Primitives): No need to inherit primitives
13202 if we are compiling with restriction No_Dispatching_Calls.
13203 (Make_Disp_XXX): Addition of assertion to avoid the use of all these
13204 subprograms if we are compiling under No_Dispatching_Calls restriction.
13205 (Make_DT): Generate a dispatch table with a single dummy entry if
13206 we are compiling with the No_Dispatching_Calls restriction. In
13207 addition, in this case we don't generate code that calls to the
13208 following run-time subprograms: Set_Type_Kind, Inherit_DT.
13209 (Make_Select_Specific_Data_Table): Add assertion to avoid the use
13210 of this subprogram if compiling with the No_Dispatching_Calls
13212 (Expand_Type_Conversion): Instead of using the actual parameter,
13213 the argument passed as parameter to the conversion function was
13214 erroneously referenced by the expander.
13215 (Ada_Actions): Addition of Get_Predefined_Prim_Op_Address,
13216 Set_Predefined_Primitive_Op_Address and Set_Signature.
13217 (Expand_Dispatching_Call): Generate call to
13218 Get_Predefined_Prim_Op_Address for predefined primitives.
13219 (Fill_DT_Entry): Generate call to Set_Predefined_Prim_Op_Address for
13220 predefined primitives.
13221 (Make_DT, Make_Secondary_DT): If the tagged type has no user defined
13222 primitives we reserve one dummy entry to ensure that the tag does not
13223 point to some memory that is associated with some other object. In
13224 addition, remove all the old code that generated the assignments
13225 associated with the signature of the dispatch table and replace them
13226 by a call to the new subprogram Set_Signature.
13227 (Set_All_DT_Position): Change the algorithm because now we have a
13228 separate dispatch table associated with predefined primitive operations.
13229 (Expand_Interface_Conversion): In case of non-static offset_to_top
13230 add explicit dereference to get access to the object after the call
13231 to displace the pointer to the object.
13232 (Expand_Interface_Thunk): Modify the generation of the actual used
13233 in the calls to the run-time function Offset_To_Top to fulfil its
13235 (Make_DT): Add the new actuals required to call Set_Offset_To_Top.
13237 2006-02-13 Ed Schonberg <schonberg@adacore.com>
13239 * exp_dist.adb (Copy_Specification): For access parameters, copy
13240 Null_Exclusion flag, which will have been set for stream subprograms
13243 2006-02-13 Pascal Obry <obry@adacore.com>
13245 * expect.c (__gnat_expect_portable_execvp): New implementation. The
13246 previous implementation was using the C runtime spawnve routine but
13247 the corresponding wait was using directly the Win32 API. This was
13248 causing some times a lock when waiting for an event using
13249 WaitForSingleObject in __gnat_waitpid. This new implementation uses
13250 the Win32 CreateProcess routine. Avoiding mixing C runtime and Win32
13251 API fixes this problem.
13253 2006-02-13 Robert Dewar <dewar@adacore.com>
13255 * exp_intr.adb (Expand_Unc_Deallocation): Correct error of bad analyze

13260 * exp_pakd.ads: Fix typos in comments.
13262 * exp_pakd.adb (Convert_To_PAT_Type): For the case of a bit packed
13263 array reference that is an explicit dereference, mark the converted
13264 (packed) array reference as analyzed to prevent a forthcoming
13265 reanalysis from resetting its type to the original (non-packed) array

13272 * exp_util.ads, exp_util.adb (Find_Prim_Op,
13273 Is_Predefined_Primitive_Operation): When
13274 searching for the predefined equality operator, verify that operands
13275 have the same type.
13276 (Is_Predefined_Dispatching_Operation): Remove the code that looks
13277 for the last entity in the list of aliased subprograms. This code
13278 was wrong in case of renamings.
13279 (Set_Renamed_Subprogram): New procedure
13280 (Remove_Side_Effects): Replace calls to Etype (Exp) with use of the
13281 Exp_Type constant computed when entering this subprogram.
13282 (Known_Null): New function
13283 (OK_To_Do_Constant_Replacement): New function
13284 (Known_Non_Null): Check scope before believing Is_Known_Non_Null flag
13285 (Side_Effect_Free): An attribute reference 'Input is not free of
13286 side effect, unlike other attributes that are functions. (from code
13288 (Remove_Side_Effects): Expressions that involve packed arrays or records
13289 are copied at the point of reference, and therefore must be marked as
13290 renamings of objects.
13291 (Is_Predefined_Dispatching_Operation): Return false if the operation is
13292 not a dispatching operation.
13295 (Remove_Side_Effects): Lift enclosing type conversion nodes for
13296 elementary types in all cases.
13298 2006-02-13 Javier Miranda <miranda@adacore.com>

13301 task types when accessing to the corresponding record type.
13302 Remove '!' in warning message.
13304 2006-02-13 Olivier Hainque <hainque@adacore.com>
13306 * g-altive.ads (VECTOR_ALIGNMENT): Set to Min (16, Max_Alignment),
13307 to avoid useless and space inefficient overalignments on targets where
13308 Max_Alignment is larger than 16.
13310 2006-02-13 Pascal Obry <obry@adacore.com>
13312 * g-catiio.adb (Sec_Number): New type used to compute the number of
13313 seconds since 1-1-1970.
13314 (Image) [Natural]: The parameter was an Integer, as we can't deal with
13315 negative numbers (years, months...) it is better to have a Natural here.
13317 (Image) [Number]: Change parameter from Long_Integer to Number.
13318 (Image): Use Number type to compute the seconds since 1-1-1970 to fix an
13319 overflow for dates past year 2038.
13321 2006-02-13 Matthew Heaney <heaney@adacore.com>
13323 * g-dyntab.adb (Index_Of): conversion from Natural can no longer raise
13326 2006-02-13 Arnaud Charlet <charlet@adacore.com>
13328 * gnatbind.adb (Scan_Bind_Arg): Replace error by warning on -M and
13330 (Gnatbind): Do not call Exit_Program (E_Success) at the end, so that
13331 finalization can occur normally.

13335 * gnatcmd.adb (Rules_Switches): New table
13336 (Add_To_Rules_Switches): New procedure
13337 (GNATCmd): For command CHECK, put all options following "-rules" in the
13338 Rules_Switches table. Append these -rules switches after the -cargs
13341 2006-02-13 Robert Dewar <dewar@adacore.com>
13343 * g-spipat.adb (Image, case PC_Assign_Imm and case PC_Assign_OnM):
13344 These two cases were generating incorrect output, and if this unit
13345 was built with checks on, generated a discriminant mismatch constraint
13348 2006-02-13 Ed Schonberg <schonberg@adacore.com>
13349 Robert Dewar <dewar@adacore.com>
13351 * lib-xref.adb (Get_Type_Reference): For a private type whose full
13352 view is an array type, indicate the component type as well, for
13353 navigation purposes.
13354 (Generate_Reference): Don't consider array ref on LHS to be a case
13355 of violating pragma Unreferenced.
13356 Do not give Ada 2005 warning except on real reference.
13358 2006-02-13 Vincent Celier <celier@adacore.com>
13360 * make.adb (Collect_Arguments_And_Compile): For VMS, when compiling the
13361 main source, add switch -mdebug-main=_ada_ so that the executable can
13362 be debugged by the standard VMS debugger.
13363 (Gnatmake): Set No_Main_Subprogram to True when there is no main
13364 subprogram, to avoid issuing -mdebug-main=_ada_ for VMS uselessly.
13365 Exit the Multi_Main_Loop when Unique_Compile is True after compilation
13366 of the last source, as the binding and linking phases are never
13368 Set all executable obsolete when rebuilding a library.
13370 * makeutl.adb (Linker_Options_Switches): Do not process empty linker
13373 2006-02-13 Javier Miranda <miranda@adacore.com>
13376 * par-ch3.adb (P_Derived_Type_Def_Or_Private_Ext_Decl): Reorganize the
13377 code to improve the error message reported when the program has
13378 declarations of abstract interface types and it is not compiled with
13379 the -gnat05 switch.
13380 (P_Access_Definition): Reorganize the code to improve the error
13381 message reported when the new Ada 2005 syntax for anonymous
13382 access types is used and the program is not compiled with the

13403 * prj.ads (Error_Warning): New enumeration type
13405 * prj-nmsc.ads, prj-nmsc.adb (Error_Msg): If location parameter is
13406 unknown, use the location of the project to report the error.
13407 (When_No_Sources): New global variable
13408 (Report_No_Ada_Sources): New procedure
13409 (Check): New parameter When_No_Sources. Set value of global variable
13411 (Find_Sources): Call Report_No_Ada_Sources when appropriate
13412 (Get_Sources_From_File): Ditto
13413 (Warn_If_Not_Sources): Better warning messages indicating the unit name
13416 * prj-pars.ads, prj-pars.adb (Parse): New parameter When_No_Sources.
13417 Call Prj.Proc.Process with parameter When_No_Sources.
13419 * prj-proc.ads, prj-proc.adb (Check): New parameter When_No_Sources.
13420 Call Recursive_Check with parameter When_No_Sources.
13421 (Recursive_Check): New parameter When_No_Sources. Call itself and
13422 Prj.Nmsc.Check with parameter When_No_Sources.
13423 (Process): New parameter When_No_Sources. Call Check with parameter
13425 (Copy_Package_Declarations): New procedure to copy renamed parameters
13426 and setting the location of the declared attributes to the location
13427 of the renamed package.

13433 * prj-makr.adb (Make): Preserve the comments from the original project
13435 When removing nodes (attributes Source_Dirs, Source_Files,
13436 Source_List_File and package Naming), save the comments and attach the
13437 saved comments to the newly created nodes.
13438 Do not add a with clause for the naming package if one already exists.
13440 2006-02-13 Javier Miranda <miranda@adacore.com>

13446 * sem_disp.adb (Override_Dispatching_Operation): Traverse the list of
13447 aliased entities to look for the overriden abstract interface
13449 (Is_Interface_Subprogram): Complete documentation.
13450 (Check_Dispatching_Operation): Do not generate code to register the
13451 operation in the dispatch table if the source is compiled with
13452 restriction No_Dispatching_Calls.
13453 (Override_Dispatching_Operation): Check for illegal attempt to override
13454 No_Return procedure with procedure that is not No_Return
13455 (Check_Dispatching_Call): Suppress the check for an abstract operation
13456 when the original node of an actual is a tag-indeterminate attribute
13457 call, since the attribute, which must be 'Input, can never be abstract.
13458 (Is_Tag_Indeterminate): Handle checking of tag indeterminacy of a
13459 call to the Input attribute (even when rewritten).
13460 (Propagate_Tag): Augment comment to indicate the possibility of a call
13461 to an Input attribute.
13463 * sem_disp.ads (Override_Dispatching_Operation): Moved to spec to allow
13464 calling it from Exp_Ch3.Make_Controlling_Function_Wrappers.
13466 * s-rident.ads: (No_Dispatching_Calls): New GNAT restriction.
13467 No_Wide_Characters is no longer partition-wide

13473 * s-auxdec-vms_64.ads (Short_Address): Wrap it in a type.
13475 2006-02-13 Javier Miranda <miranda@adacore.com>
13477 * sem_aggr.adb (Resolve_Record_Aggregate): Restructure the code that
13478 handles default-initialized components to keep separate the management
13479 of this feature but also avoid the unrequired resolution and
13480 expansion of components that do not have partially initialized
13482 (Collect_Aggr_Bounds): Add '\' in 2-line warning message.
13483 (Check_Bounds): Likewise.
13484 (Check_Length): Likewise.
13486 2006-02-13 Javier Miranda <miranda@adacore.com>
13487 Ed Schonberg <schonberg@adacore.com>
13489 * sem_attr.adb (Analyze_Attribute): In case of 'Class applied to an
13490 abstract interface type call analyze_and_resolve to expand the type
13491 conversion into the corresponding displacement of the
13492 reference to the base of the object.
13493 (Eval_Attribute, case Width): For systems where IEEE extended precision
13494 is supported, the maximum exponent occupies 4 decimal digits.
13495 (Accessibility_Message): Add '\' in 2-line warning message.
13496 (Resolve_Attribute): Likewise.
13497 (case Attribute_Access): Significantly revise checks
13498 for illegal access-to-subprogram Access attributes to properly enforce
13499 the rules of 3.10.2(32/2).
13500 Diagnose use of current instance with an illegal attribute.
13502 * sem_util.ads, sem_util.adb (Enclosing_Generic_Body): Change formal
13504 (Enclosing_Generic_Unit): New function to return a node's innermost
13505 enclosing generic declaration node.
13506 (Compile_Time_Constraint_Error): Remove '!' in warning messages.
13507 (Type_Access_Level): The accessibility level of anonymous acccess types
13508 associated with discriminants is that of the current instance of the
13509 type, and that's deeper than the type itself (AARM 3.10.2 (12.3.21)).
13510 (Compile_Time_Constraint_Error): Handle case of conditional expression.
13511 (Kill_Current_Values_For_Entity): New function
13512 (Enter_Name): Change formal type to Entity_Id
13514 2006-02-13 Hristian Kirtchev <kirtchev@adacore.com>
13515 Ed Schonberg <schonberg@adacore.com>
13516 Gary Dismukes <dismukes@adacore.com>
13518 * sem_ch10.adb (Check_Redundant_Withs): New procedure in
13519 Analyze_Compilation_Unit.
13520 Detect and warn on redundant with clauses detected in a package spec
13521 and/or body when -gnatwr is used.
13522 (Analyze_Context): Analyze config pragmas before other items
13523 (Install_Context_Items): Don't analyze config pragmas here
13524 (Install_Limited_Withed_Unit): Set limited entity of package in
13525 with_clause so that cross-reference information or warning messages on
13526 unused packages can be properly generated
13527 (Is_Visible_Through_Renamings): Return false if the limited_with_clause
13528 has Error_Posted set. Prevent infinite loops in illegal programs.
13529 (Check_Private_Child_Unit): Move test for a nonprivate with clause down
13530 to the point of the error test requiring the current unit to be private.
13531 This ensures that private with clauses are not exempted from the basic
13532 checking for being a descendant of the same library unit parent as a
13533 withed private descendant unit.
13534 (Check_Private_Limited_Withed_Unit): Revise the checking algorithm to
13535 handle private with clauses properly, as well as to account for cases
13536 where the withed unit is a public descendant of a private ancestor
13537 (in which case the current unit must be a descendant of the private
13538 ancestor's parent). The spec comments were updated accordingly. Also,
13539 the old error message in this subprogram was replaced with error
13540 messages that mirror the errors tested and reported by
13541 Check_Private_Child_Unit.
13542 Parameter and variable names improved for readability.
13543 (Install_Limited_Context_Clauses): Remove test for a withed unit being
13544 private as the precondition for calling
13545 Check_Private_Limited_Withed_Unit since that subprogram has been
13546 revised to test public units as well as private units.

13551 Javier Miranda <miranda@adacore.com>
13553 * sem_ch12.adb (Inline_Instance_Body): Remove erroneous assumption
13554 that Scope_Stack.First = 1.
13555 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
13556 were not always properly handled previously.
13557 (Formal_Entity): Complete rewrite, to handle properly some complex case
13558 with multiple levels of parametrization by formal packages.
13559 (Analyze_Formal_Derived_Type): Propagate Ada 2005 "limited" indicator
13560 to the corresponding derived type declaration for proper semantics.
13562 * sem_prag.adb (Analyze_Pragma): Remove '!' in warning message.
13563 (Check_Component): Enforce restriction on components of
13564 unchecked_unions: a component in a variant cannot contain tasks or
13566 (Unchecked_Union): Allow nested variants and multiple discriminants, to
13568 Add pragma Ada_2005 (synonym for Ada_05)
13569 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
13570 were not always properly handled previously.
13571 Document that pragma Propagate_Exceptions has no effect
13572 (Analyze_Pragma, case Pure): Set new flag Has_Pragma_Pure
13573 (Set_Convention_From_Pragma): Check that if a convention is
13574 specified for a dispatching operation, then it must be
13575 consistent with the existing convention for the operation.
13576 (CPP_Class): Because of the C++ ABI compatibility, the programmer is no
13577 longer required to specify an vtable-ptr component in the record. For
13578 compatibility reasons we leave the support for the previous definition.
13579 (Analyze_Pragma, case No_Return): Allow multiple arguments
13581 * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a
13582 non-overrideen inherited operation with a controlling result as
13583 illegal only its implicit declaration comes from the derived type
13584 declaration of its result's type.
13585 (Check_Possible_Deferred_Completion): Relocate the object definition
13586 node of the subtype indication of a deferred constant completion rather
13587 than directly analyzing it. The analysis of the generated subtype will
13588 correctly decorate the GNAT tree.
13589 (Record_Type_Declaration): Check whether this is a declaration for a
13590 limited derived record before analyzing components.
13591 (Analyze_Component_Declaration): Diagnose record types not explicitly
13592 declared limited when a component has a limited type.
13593 (Build_Derived_Record_Type): Code reorganization to check if some of
13594 the inherited subprograms of a tagged type cover interface primitives.
13595 This check was missing in case of a full-type associated with a private
13597 (Constant_Redeclaration): Check that the subtypes of the partial and the
13598 full view of a constrained deferred constant statically match.
13599 (Mentions_T): A reference to the current type in an anonymous access
13600 component declaration must be an entity name.
13601 (Make_Incomplete_Type_Declaration): If type is tagged, set type of
13602 class_wide type to refer to full type, not to the incomplete one.
13603 (Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not
13604 available. Required to give support to the certified run-time.
13605 (Analyze_Component_Declaration): In case of anonymous access components
13606 perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2).
13607 (Process_Discriminants): For an access discriminant, use the
13608 discriminant specification as the associated_node_for_itype, to
13609 simplify accessibility checks.
13611 2006-02-13 Ed Schonberg <schonberg@adacore.com>
13612 Javier Miranda <miranda@adacore.com>
13614 * sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
13615 abstract interpretations on an operator, remove interpretations that
13616 yield Address or a type derived from it, if one of the operands is an
13618 (Try_Object_Operation.Try_Primitive_Operation,
13619 Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
13620 location when creating the new reference to a primitive or class-wide
13621 operation as a part of rewriting a subprogram call.
13622 (Try_Primitive_Operations): If context requires a function, collect all
13623 interpretations after the first match, because there may be primitive
13624 operations of the same type with the same profile and different return
13625 types. From code reading.
13626 (Try_Primitive_Operation): Use the node kind to choose the proper
13627 operation when a function and a procedure have the same parameter
13629 (Complete_Object_Operation): If formal is an access parameter and prefix
13630 is an object, rewrite as an Access reference, to match signature of
13631 primitive operation.
13632 (Find_Equality_Type, Find_One_Interp): Handle properly equality given
13633 by an expanded name with prefix Standard, when the operands are of an
13634 anonymous access type.
13635 (Remove_Abstract_Operations): If the operation is abstract because it is
13636 inherited by a user-defined type derived from Address, remove it as
13637 well from the set of candidate interpretations of an overloaded node.
13638 (Analyze_Membership_Op): Membership test not applicable to cpp-class
13641 2006-02-13 Bob Duff <duff@adacore.com>
13643 * sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
13644 redundant use clauses.
13645 In particular, if the scope of two use clauses overlaps, but one is not
13646 entirely included in the other, we should not warn. This can happen
13647 with nested packages.
13648 (Analyze_Subprogram_Renaming): Protect the compiler against previously
13649 reported errors. The bug was reported when the compiler was built
13650 with assertions enabled.
13651 (Find_Type): If the node is a 'Class reference and the prefix is a
13652 synchronized type without a corresponding record, return the type
13655 2006-02-13 Javier Miranda <miranda@adacore.com>
13657 * sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): Check that
13658 if this is the full-declaration associated with a private declaration
13659 that implement interfaces, then the private type declaration must be
13661 (Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
13662 as aliased. The use of the 'access attribute is not available for such
13663 object (for this purpose the object should be explicitly marked as
13664 aliased, but being an anonymous type this is not possible).
13666 2006-02-13 Ed Schonberg <schonberg@adacore.com>
13667 Robert Dewar <dewar@adacore.com>
13669 * sem_elab.adb (Same_Elaboration_Scope): A package that is a
13670 compilation unit is an elaboration scope.
13671 (Add_Task_Proc): Add '\' in 2-line warning message.
13672 (Activate_All_Desirable): Deal with case of unit with'ed by parent
13674 2006-02-13 Ed Schonberg <schonberg@adacore.com>
13675 Javier Miranda <miranda@adacore.com>
13677 * sem_type.adb (Write_Overloads): Improve display of candidate
13679 (Add_One_Interp): Do not add to the list of interpretations aliased
13680 entities corresponding with an abstract interface type that is an
13681 immediate ancestor of a tagged type; otherwise we have a dummy
13682 conflict between this entity and the aliased entity.
13683 (Disambiguate): The predefined equality on universal_access is not
13684 usable if there is a user-defined equality with the proper signature,
13685 declared in the same declarative part as the designated type.
13686 (Find_Unique_Type): The universal_access equality operator defined under
13687 AI-230 does not cover pool specific access types.
13688 (Covers): If one of the types is a generic actual subtype, check whether
13689 it matches the partial view of the other type.
13691 2006-02-13 Thomas Quinot <quinot@adacore.com>
13693 * sinput-d.adb (Write_Line): Update the Source_Index_Table after each
13694 line. This is necessary to allow In_Extended_Main_Unit to provide
13695 correct results for itypes while writing out expanded source.
13696 (Close_File): No need to update the source_index_table here since it's
13697 now done for each line.
13699 2006-02-13 Ed Schonberg <schonberg@adacore.com>
13700 Robert Dewar <dewar@adacore.com>
13702 * sprint.adb (Write_Itype): Preserve Sloc of declaration, if any, to
13703 preserve the source unit where the itype is declared, and prevent a
13705 (Note_Implicit_Run_Time_Call): New procedure
13706 (Write_Itype): Handle missing cases (E_Class_Wide_Type and
13709 * sprint.ads: Document use of $ for implicit run time routine call
13711 2006-02-13 Quentin Ochem <ochem@adacore.com>
13713 * s-stausa.adb (Initialize_Analyzer): fixed error in assignment of
13716 2006-02-13 Bob Duff <duff@adacore.com>
13718 * s-valint.adb (Scan_Integer): Call Scan_Raw_Unsigned instead of
13719 Scan_Unsigned, so we do not scan leading blanks and sign twice.
13720 Integer'Value("- 5") and Integer'Value("-+5") now correctly
13721 raise Constraint_Error.
13723 * s-vallli.adb (Scan_Long_Long_Integer): Call
13724 Scan_Raw_Long_Long_Unsigned instead of Scan_Long_Long_Unsigned, so we
13725 do not scan leading blanks and sign twice.
13726 Integer'Value("- 5") and Integer'Value("-+5") now correctly
13727 raise Constraint_Error.
13729 * s-valllu.ads, s-valllu.adb (Scan_Raw_Long_Long_Unsigned,
13730 Scan_Long_Long_Unsigned): Split out most of the processing from
13731 Scan_Long_Long_Unsigned out into
13732 Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.
13733 This prevents scanning leading blanks and sign twice.
13734 Also fixed a bug: Modular'Value("-0") should raise Constraint_Error
13737 * s-valuns.ads, s-valuns.adb (Scan_Raw_Unsigned, Scan_Unsigned): Split
13738 out most of the processing from Scan_Unsigned out into
13739 Scan_Raw_Unsigned, so that Val_LLI can call the Raw_ version.
13740 This prevents scanning leading blanks and sign twice.
13742 * s-valuti.ads, s-valuti.adb (Scan_Plus_Sign): Add Scan_Plus_Sign, for
13743 use with Modular'Value attribute.
13744 (Scan_Plus_Sign): Add Scan_Plus_Sign, for use with Modular'Value

13944 * a-elchha.adb (Last_Chance_Handler): Change the task termination soft
13945 link to the version that does nothing. This way the task termination

13947 because of an unhandled exception.
13949 * a-exextr.adb (Notify_Unhandled_Exception): Call the task termination
13950 handler because of an unhandled exception.
13952 * a-taside.adb (Abort_Tasks): Call the Abort_Tasks procedure from

13958 * s-soflin.ads, s-soflin.adb (Task_Termination_NT): Add this
13959 non-tasking version of the soft link for task termination. We do
13960 nothing since if we are using the non-tasking version it
13961 means that the task termination functionality is not used.
13962 (Null_Finalize_Global_List): Add this null version for the procedure
13963 in charge of finalizing the global list for controlled objects.
13964 (Null_Adafinal): Remove this procedure. Adafinal_NT has been created
13965 instead for handling run-time termination in a more flexible way.
13966 (Adafinal_NT): This new procedure will take care of finalizing the
13967 global list for controlled objects if needed, but no tasking
13970 * s-tarest.adb (Task_Lock): Do not try to lock again the
13971 Global_Task_Lock if we already own it. Otherwise, we get blocked in
13972 some run-time operations.
13973 (Task_Unlock): Do not try to actually unlock the Global_Task_Lock
13974 until all nested locks have been released.
13975 (Task_Wrapper): Call the fall-back task termination handler. It
13976 applies to all tasks but the environment task.
13977 (Finalize_Global_Tasks): Add the call for the task termination
13978 procedure for the environment task.
13979 (Task_Wrapper): suppress warnings around declaration of
13980 Secondary_Stack_Address.
13982 * s-tasini.adb (Final_Task_Unlock): Global_Task_Lock_Nesting has been
13983 moved to the Common_ATCB record.
13984 (Task_Lock): Global_Task_Lock_Nesting has been moved to the
13985 Common_ATCB record.
13986 (Task_Unlock): Global_Task_Lock_Nesting has been moved to the
13987 Common_ATCB record.
13989 * s-taskin.adb (Initialize_ATCB): Initialize Global_Task_Lock_Nesting,
13990 Fall_Back_Handler, and Specific_Handler.

13993 defined in Ada.Task_Termination, to avoid circular dependencies.
13994 (Termination_Handler): Redefine this type here, alredy defined in
13995 Ada.Task_Termination, for avoiding circular dependencies.
13996 (Common_ATCB): Add the Fall_Back_Handler and Specific_Handler required
13997 for storing task termination handlers. In addition,
13998 Global_Task_Lock_Nesting has been moved from Ada_Task_Control_Block to
13999 Common_ATCB because it is used by both the regular and the restricted
14001 (Ada_Task_Control_Block): Move Global_Task_Lock_Nesting from here to
14002 Common_ATCB because it is used by both the regular and the restricted
14004 (Common_ATCB): Added a dynamic task analyzer field.
14006 * s-tassta.adb (Abort_Tasks): Move the code in charge of checking
14007 potentially blocking operations to System.Tasking.Utilities.Abort_Tasks.
14008 (Task_Wrapper): Call the task termination handler. It applies to all
14009 tasks but the environment task.
14010 (Finalize_Global_Tasks): Call the task termination procedure for the
14011 environment task. The call to Finalize_Global_List is now performed
14012 using the soft links mechanism.
14013 (Task_Wrapper): added dynamic stack analysis.
14015 * s-tasuti.adb (Abort_Tasks): The code in charge of checking
14016 potentially blocking operations has been moved from
14017 System.Tasking.Stages.Abort_Tasks to this procedure. There can be
14018 direct calls to System.Tasking.Utilities.Abort_Tasks that do not pass
14019 through System.Tasking.Stages.Abort_Tasks, and we do not want to miss
14020 this run-time check.
14022 * s-solita.adb (Task_Termination_Handler_T): Add this task-safe version
14023 of task termination procedure.
14024 (Init_Tasking_Soft_Links): Install the task-safe version of the soft
14025 link for the task termination procedure.

14066 * a-tags.ads, a-tags.adb (Offset_To_Top): Moved from the package body
14067 to the specification because the frontend generates code that uses this
14069 (Set_Interface_Table): Add missing assertion.
14070 Update documentation describing the run-time structure.
14071 (Displace): New subprogram that displaces the pointer to the object
14072 to reference one of its secondary dispatch tables.
14073 (IW_Membership): Modified to use the new table of interfaces.
14074 (Inherit_TSD): Modified to use the new table of interfaces.
14075 (Register_Interface_Tag): Use the additional formal to fill the
14076 contents of the new table of interfaces.
14077 (Set_Interface_Table): New subprogram that stores in the TSD the
14078 pointer to the table of interfaces.

14092 * exp_ch6.adb (Register_Interface_DT_Entry): Remove the Thunk_Id actual
14093 in all the calls to Expand_Interface_Thunk. Instead of referencing the
14094 record component containing the tag of the secondary dispatch table we
14095 have to use the Offset_To_Top run-time function to get this information;
14096 otherwise if the pointer to the base of the object has been displace
14097 we get a wrong value if we use the 'position attribute.
14099 * exp_disp.adb (Expand_Interface_Thunk): Remove the Thunk_Id actual in
14100 all the calls to Expand_Interface_Thunk.
14101 (Make_Secondary_DT): Secondary dispatch tables do not have a table of

14104 ensure that the interfaces implemented by the ancestors are placed
14105 at the header of the generated list.
14106 (Expand_Interface_Conversion): Handle the case in which the displacement
14107 associated with the interface conversion is not statically known. In
14108 this case we generate a call to the new run-time subprogram Displace.

14110 (Ada_Actions, Action_Is_Proc, Action_Nb_Arg): Add entries for
14111 Get_Tagged_Kind and Set_Tagged_Kind.
14112 (Tagged_Kind): New function that determines the tagged kind of a type
14113 with respect to limitedness and concurrency and returns a reference to

14116 Make_Disp_Timed_Select_Body): Correctly retrieve the pointer to the
14117 primary dispatch table for a type.

14119 secondary dispatch table respectively of a tagged type.
14121 * exp_disp.ads (Expand_Interface_Thunk): Remove Thunk_Id formal.

14133 Set_Tagged_Kind, RE_Tagged_Kind, RE_TK_Abstract_Limited_Tagged,
14134 RE_TK_Abstract_Tagged, RE_TK_Limited_Tagged, RE_TK_Protected,
14135 RE_TK_Tagged, RE_TK_Task.
14137 * exp_ch3.adb (Init_Secondary_Tags): Modify the subprogram
14138 Init_Secondary_Tags_Internal to allow its use with interface types and
14139 also to generate the code for the new additional actual required
14140 by Set_Offset_To_Top.
14141 (Build_Init_Statements): In case of components associated with abstract
14142 interface types there is no need to generate a call to its IP.
14143 (Freeze_Record_Type): Generate Select Specific Data tables only for
14145 (Make_Predefined_Primitive_Specs, Predefined_Primitive_Bodies): Generate
14146 the bodies and specifications of the predefined primitive operations
14147 dealing with dispatching selects and abort, 'Callable, 'Terminated only
14148 for concurrent types.
14150 * exp_sel.ads, exp_sel.adb: New files.
14152 * exp_ch9.adb (Build_Protected_Entry, Expand_N_Protected_Body,
14153 Expand_N_Protected_Type_Declaration, Make_Initialize_Protection): Handle
14154 properly protected objects and attach handler in the case of the
14155 restricted profile.
14156 Move embeded package Select_Expansion_Utilities into a separate external
14158 (Expand_N_Asynchronous_Select, Expand_N_Conditional_Select,
14159 Expand_N_Timed_Entry_Call): Correct calls external package Exp_Sel.
14160 (Build_K, Build_S_Assignment): New subprograms, part of the select
14161 expansion utilities.

14164 where the trigger is a dispatching procedure of a limited tagged type.
14166 2005-12-09 Olivier Hainque <hainque@adacore.com>
14168 * decl.c (gnat_to_gnu_entity, renaming object case): Don't early expand
14169 pointer initialization values. Make a SAVE_EXPR instead. Add comments
14170 about the use and expansion of SAVE_EXPRs in the various possible
14171 renaming handling cases.
14172 (components_to_record, compare_field_bitpos): Sort by DECL_UID, not by
14173 abusing DECL_FCONTEXT.

14273 covered by the tag of the source.
14275 2005-12-09 Robert Dewar <dewar@adacore.com>
14277 * exp_imgv.adb (Expand_Image_Attribute): Generate extra boolean

14292 component associated with the secondary table of an abstract interface
14293 type, return the entity associated with such abstract interface type.
14294 (Make_Subtype_From_Expr): If type has unknown discriminants, always use
14295 base type to create anonymous subtype, because entity may be a locally
14296 declared subtype or generic actual.
14297 (Find_Interface): New subprogram that given a tagged type and one of its
14298 component associated with the secondary table of an abstract interface
14299 type, return the entity associated with such abstract interface type.
14301 * sem_res.adb (Resolve_Type_Conversion): Handle the case in which the
14302 conversion cannot be handled at compile time. In this case we pass this
14303 information to the expander to generate the appropriate code.

14339 the size and positional fields of the new component.
14340 (Analyze_Component_Declaration): A limited component is
14341 legal within a protected type that implements an interface.
14342 (Collect_Interfaces): Do not add to the list the interfaces that
14343 are implemented by the ancestors.
14344 (Derived_Type_Declaration): If the parent of the full-view is an
14345 interface perform a transformation of the tree to ensure that it has
14346 the same parent than the partial-view. This simplifies the job of the
14347 expander in order to generate the correct object layout, and it is
14348 needed because the list of interfaces of the full-view can be given in
14350 (Process_Full_View): The parent of the full-view does not need to be
14351 a descendant of the parent of the partial view if both parents are
14353 (Analyze_Private_Extension_Declaration): If declaration has an explicit
14354 "limited" the parent must be a limited type.
14355 (Build_Derived_Record_Type): A derived type that is explicitly limited
14356 must have limited ancestor and progenitors.
14357 (Build_Derived_Type): Ditto.

14368 (Process_Full_View): Improve the check for the "no hidden interface"
14369 rule as defined by AI-396.
14371 2005-12-09 Robert Dewar <dewar@adacore.com>
14373 * freeze.adb (Freeze_Record_Type): Only test for useless pack on record
14374 types, not on record subtypes.
14375 (Freeze_Entity): Code cleanup. Add barrier to the loop
14376 that generates the references for primitive operations. This allows to
14377 remove an unnecessary exception handler.

14428 available user-specified stream attributes on limited parameters to
14429 also test the type directly rather than only its underlying type (for
14430 Ada 95) and, in the case of Ada 2005, to check that the user-specified
14431 attributes are visible at the point of the subprogram declaration.
14432 For Ada 2005, the error message is modified to indicate that the
14433 type's stream attributes must be visible (again, only for -gnat05).

14465 types use the corresponding record type. This was not needed before
14466 the implementation of Ada 2005 synchronized types because
14467 concurrent types were never tagged types in Ada 95.

14593 2005-11-21 Joel Sherrill <joel.sherrill@oarcorp.com>
14595 * socket.c: Add extern int h_errno for rtems since networking header
14596 files are not available at this point in a tool bootstrap. Newlib

14600 Roger Sayle <roger@eyesopen.com>
14603 * misc.c (internal_error_function): Don't use vsprintf to format
14604 the error message text, instead use pp_format_text and the new

14615 * trans.c (gnat_gimplify_expr, case ADDR_EXPR): Always make
14616 a temporary if taking the address of something that is neither
14617 reference, declaration, or constant, since the gimplifier
14618 can't handle that case.
14620 2005-11-17 Laurent GUERBY <laurent@guerby.net>
14623 * s-auxdec-empty.ads, s-auxdec-empty.adb: New files.

14691 TARGET, as it has the form of a math expression, and some components
14692 may be platform-defined macros.
14693 For VxWorks, generate the OK and ERROR values.
14694 New constants giving the sizes of the components of C struct timeval.

14700 * types.ads: Include All_Checks in Suppress_Array
14702 * checks.adb (Check_Needed): Remove kludge for a/=b rewritten as
14703 not(a=b), since we no longer do this rewriting, and hence it is not
14705 (Elaboration_Checks_Suppressed): Add special casing to
14706 deal with different cases of static and dynamic elaboration checks (all
14707 checks does not count in the first case, but does in the second).
14708 (Expr_Known_Valid): Do not assume that the result of any arbitrary
14709 function call is valid, since this is not the case.
14710 (Ensure_Valid): Do not apply validity check to a real literal
14711 in a universal or fixed context
14713 * exp_ch4.adb (Expand_N_Op_Ne): Don't expand a/=b to not(a=b) for
14714 elementary types using the operator in standard. It is cleaner not to
14715 modify the programmers intent, especially in the case of floating-point.
14716 (Rewrite_Comparison): Fix handling of /= (this was always wrong, but
14717 it did not matter because we always rewrote a/=b to not(a=b).
14718 (Expand_Allocator_Expression): For an allocator expression whose nominal
14719 subtype is an unconstrained packed type, convert the expression to its
14720 actual constrained subtype.
14721 Implement warning for <= or >= where < or > not possible
14722 Fix to Vax_Float tests (too early in many routines, causing premature
14723 Vax_Float expansions.
14725 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Allow this pragma
14726 to be used with packages and generic packages as well as with
14728 (Suppress): Set All_Checks, but not Elaboration_Check, for case
14729 of pragma Suppress (All_Checks)
14730 (Analyze_Pragma, case Warnings): Implement first argument allowed to be
14731 a string literal for precise control over warnings.
14732 Avoid raise of pragma in case of unrecognized pragma and just return
14735 * sem_prag.ads: Minor reformatting
14737 * switch-c.adb (Scan_Front_End_Switches): Replace "raise Bad_Switch;"
14738 with call to new procedure Bad_Switch. Call Scan_Pos with new parameter
14739 Switch. Do not handle any exception.
14740 Include -gnatwx as part of -gnatg (warn on redundant parens)
14741 Allow optional = after -gnatm
14742 (Scan_Front_End_Switches): The -gnatp switch sets All_Checks, but no
14743 longer sets Elaboration_Checks.
14744 Code to set warning mode moved to Sem_Warn
14745 so that it can be shared by pragma processing.
14747 * s-mastop-tru64.adb (Pop_Frame): Remove redundant parentheses in if
14750 * s-taprop-solaris.adb:
14751 Change some <= to =, to avoid new warning

14755 Fix obvious typo (Total_Errors_Detected <= 0 should be = 0)
14757 2005-11-14 Robert Dewar <dewar@adacore.com>
14759 * exp_vfpt.adb: Handle /= case
14760 (Expand_Vax_Conversion): Properly recognize Conversion_OK flag

14872 we are not defining the type.
14873 <E_Record_Type>: Likewise.
14874 (gnat_to_gnu_entity) <object, renaming>: Adjust comments and structure
14875 to get advantage of the new maybe_stabilize_reference interface, to
14876 ensure that what we reference is indeed stabilized instead of relying
14877 on assumptions on what the stabilizer does.
14878 (gnat_to_gnu_entity) <E_Incomplete_Type>: If the entity is an incomplete
14879 type imported through a limited_with clause, use its non-limited view.
14880 (Has_Stdcall_Convention): New macro, to centralize the Windows vs others
14882 (gnat_to_gnu_entity): Use Has_Stdcall_Convention instead of a spread mix
14883 of #if sections + explicit comparisons of convention identifiers.

14885 before early-returning for certain types when code generation is
14887 (gnat_to_gnu_entity) <object>: Adjust comment attached to the
14888 nullification of gnu_expr we do for objects with address clause and
14889 that we are not defining.
14890 (elaborate_expression_1): Do not create constants when creating
14891 variables needed by the debug info: the dwarf2 writer considers that
14892 CONST_DECLs is used only to represent enumeration constants, and emits
14894 (gnat_to_gnu_entity) <object>: When turning a non-definition of an
14895 object with an address clause into an indirect reference, drop the
14896 initializing expression.

14907 if there is an actual subtype provided by the front-end, use that
14908 subtype to build an actual type with bounds template.
14909 (tree_transform, case N_Free_Statement): If an Actual_Designated_Subtype
14910 is provided by the front-end, use that subtype to compute the size of
14911 the deallocated object.

14913 check for a potential violation of a No_Elaboration_Code restriction.

14918 maybe_stabilize, for common uses without restriction on lvalues and
14919 without need to check for the success indication.
14920 (gnat_to_gnu, call_to_gnu): Adjust calls to gnat_stabilize_reference, to
14921 pass false instead of 0 as the FORCE argument which is a bool.
14922 (Identifier_to_gnu): Remove checks ensuring that an renamed object
14923 attached to a renaming pointer has been properly stabilized, as no such
14924 object is attached otherwise.
14925 (call_to_gnu): Invoke create_var_decl to create the temporary when the
14926 function uses the "target pointer" return mechanism.
14927 Reinstate conversion of the actual to the type of the formal
14928 parameter before any other specific treatment based on the passing
14929 mechanism. This turns out to be necessary in order for PLACEHOLDER
14930 substitution to work properly when the latter type is unconstrained.

14934 (maybe_stabilize_reference): New function, like gnat_stabilize_reference
14935 with extra arguments to control whether to recurse through non-values
14936 and to let the caller know if the stabilization has succeeded.
14938 * utils2.c (gnat_build_constructor): Only sort the fields for possible
14939 static output of record constructor if all the components are constant.
14940 (gnat_build_constructor): For a record type, sort the list of field
14941 initializers in increasing bit position order.
14942 Factor common code to build a storage type for an unconstrained object
14943 from a fat or thin pointer type and a constrained object type.
14944 (build_unary_op) <ADDR_EXPR>: Always recurse down conversions between
14945 types variants, and process special cases of VIEW_CONVERT expressions
14946 as their NOP_EXPR counterpart to ensure we get to the
14947 CORRESPONDING_VARs associated with CONST_DECls.
14948 (build_binary_op) <MODIFY_EXPR>: Do not strip VIEW_CONVERT_EXPRs
14949 on the right-hand side.
14951 * utils.c (build_unc_object_type_from_ptr): New subprogram, factoring
14953 (convert) <VIEW_CONVERT_EXPR>: Return the inner operand directly if we
14954 are converting back to its original type.
14955 (convert) <JM input>: Fallthrough regular conversion code instead of
14956 extracting the object if converting to a type variant.
14957 (create_var_decl): When a variable has an initializer requiring code
14958 generation and we are at the top level, check for a potential violation
14959 of a No_Elaboration_Code restriction.
14960 (create_var_decl): call expand_decl for CONST_DECLs, to set MODE, ALIGN
14961 SIZE and SIZE_UNIT which we need for later back-annotations.

14963 <VIEW_CONVERT_EXPR>: Do not lift the conversion if the target type
14964 is an unchecked union.
14965 (pushdecl): Set DECL_NO_STATIC_CHAIN on imported nested functions.
14966 (convert) <VIEW_CONVERT_EXPR>: When the types have the same
14967 main variant, just replace the VIEW_CONVERT_EXPR.

15103 * exp_aggr.adb (Build_Record_Aggr_Code): Do not create master entity
15104 for task component, in the case of a limited aggregate. The enclosed

15144 access to unconstrained packed array type, annotate the dereference
15145 with an actual subtype so GIGI can make a correct size computation.
15146 (Expand_N_Attribute_Reference): In case of 'Unchecked_Access and
15147 'Unrestricted_Access, if the designated type is an interface we
15148 add a type conversion to force the displacement of the pointer
15149 to the secondary dispatch table.
15150 Use Universal_Real instead of Long_Long_Float when we need a high
15151 precision float type for the generated code (prevents gratuitous
15152 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
15153 (Expand_N_Attribute_Reference): Add support for attribute 'Callable and
15154 'Terminated for task interface class-wide objects. Generate a call to
15155 the predefined dispatching routine used to retrieve the _task_id from
15156 a task corresponding record.

15176 assignment of a value of a tagged type that has been rewritten to a

15180 (Expand_N_If_Statement): When killing a dead then-branch in an
15181 if-statement that has elsif_parts, recompute the Current_Value node
15182 for any entity whose value is known from the condition of the first
15184 (Expand_N_Return_Statement): When returning a mutable record, convert
15185 the return value into its actual subtype in order to help the backend
15186 to return the actual size instead of the maximum. This is another
15187 aftermath of not returning mutable records on the sec-stack anymore.
15189 * sem_ch5.ads, sem_ch5.adb (Analyze_Iteration_Scheme): Minor change to
15190 handling of error msg for suspicious reverse range iteration.
15191 (Check_Possible_Current_Value_Condition): Move declaration from body to

15202 * expect.c (__gnat_kill) [Win32]: Fix implementation, the pid returned
15203 by spawnve is a process handle, no need to convert. Add a parameter
15204 close to control wether the process handle must be closed.
15205 (__gnat_waitpid): Fix implementation, the pid returned by spawnve is
15206 a process handle, not need to convert.
15207 (__gnat_kill) [*]: Add dummy parameter close to match the Win32 spec.
15209 * g-expect.adb: (Kill): Document the new close parameter.

15517 In addition some minor reorganization of the code has been done to
15518 leave it more clear.
15519 (Analyze_Type_Declaration): If type has previous incomplete tagged

15576 whose default is abstract because the object type itself is abstract.
15577 (Find_Type): If the type is incomplete and appears as the prefix of a
15578 'Class reference, it is tagged, and its list of primitive operations
15579 must be initialized properly.

16654 position set is provided, we compute one in order to reduce the maximum
16655 length of the keys. This computation first selects a character
16656 position between 1 and the minimum length of the keys in order to
16657 avoid reducing one of the keys to an empty string.
16658 (Initialize, Compute): When the ratio V to K is too low, the algorithm
16659 does not converge. The initialization procedure now comes with a

16811 2005-09-01 Robert Dewar <dewar@adacore.com>
16813 * sem_cat.adb (Check_Categorization_Dependencies): Add more detail to
16814 error msgs for most common cases.
16815 Use new errout insertion char < (conditional warning)
16817 2005-09-01 Javier Miranda <miranda@adacore.com>
16818 Ed Schonberg <schonberg@adacore.com>
16820 * sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
16821 become local to the whole package.
16822 (Install_Limited_Withed_Unit): Instead of unchaining real entities if
16823 the package was already analyzed the new algorithm "replaces" the
16824 real entities by the shadow ones. This is required to ensure that
16825 the order of these entities in the homonym chains does not change;
16826 otherwise we can have undefined references at linking time because
16827 in case of conflicts the external name of the entities will have
16828 a suffix that depends on the order of the entities in the chain.
16829 (Remove_Limited_With_Clause): Complementary code that completes the
16830 new algorithm and replaces the shadow entities by the real ones.
16831 (Install_Limited_Withed_Unit): When unchaining entities before the
16832 installation of the shadow entities, only regular entities of the
16833 public part must be taken into account. This is required to
16834 keep this routine in synch with the work done by Remove_Limited_
16836 (Install_Limited_With_Clause): Introduce implicit limited_with_clause
16837 even if unit is analyzed, because the analysis of the unit is
16838 idempotent in any case, and the limited view of the unit may have to
16839 be installed for proper visibility.
16840 (Expand_Limited_With_Clause): Even if the unit in the implicit
16841 with_clause has been analyzed already, a limited view of the package
16842 must be built for the current context, if it does not exist yet.

16845 Javier Miranda <miranda@adacore.com>
16846 Gary Dismukes <dismukes@adacore.com>
16848 * sem_ch12.adb (Instantiate_Subprogram_Body): When creating the
16849 defining entity for the instance body, make a new defining identifier
16850 rather than copying the entity of the spec, to prevent accidental
16851 sharing of the entity list.
16852 (Check_Private_View): When exchanging views of private types, build the
16853 list of exchanged views as a stack, to ensure that on exit the exchanges
16854 are undone in the proper order.
16855 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation):
16856 Restore the compilation environment in case of instantiation_error.
16857 (Analyze_Generic_Subprogram_Declaration): Handle creation of type entity
16858 for an anonymous access result.
16859 (Instantiate_Generic_Subprogram): Subtype_Mark => Result_Definition
16860 (Formal_Entity): Handle properly the case of a formal package that
16861 denotes a generic package renaming.
16863 2005-09-01 Thomas Quinot <quinot@adacore.com>
16865 * sem_ch13.adb (Analyze_Enumeration_Representation_Clause): Reject the
16866 clause if the array aggregate is surrounded by parentheses.
16868 2005-09-01 Cyrille Comar <comar@adacore.com>
16869 Gary Dismukes <dismukes@adacore.com>
16870 Ed Schonberg <schonberg@adacore.com>
16871 Javier Miranda <miranda@adacore.com>
16873 * sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
16875 to check if a type is Constrained in cases related to code generation
16876 (rather than semantic checking) since otherwise we do not generate
16877 similar code for mutable private types depending if their
16878 discriminants are visible or not.
16879 (Check_Abstract_Overriding): Do not complain about failure to override
16880 the primitive operations used in dispatching selects since they will
16881 always be overriden at the freeze point of the type.
16882 (Access_Definition): Separate out handling for resetting the scope
16883 of an anonymous access function result type. Retrieve the scope
16884 of the associated function rather than using Current_Scope, which
16885 does not have a consistent value (depends on whether we're in the
16886 middle of analyzing formal parameters). Add ??? comment about
16887 finding a cleaner way to handle the special cases of scope setting.
16888 (Process_Incomplete_Dependents): A protected operation is never a
16889 dispatching operation (only its wrapper may be).
16890 (Build_Derived_Record_Type): In case of tagged private types that
16891 implement interfaces add derivation of predefined primitive
16893 (Derive_Subprograms): Replace the Is_Interface_Derivation parameter
16894 by two parameters that are used in case of derivation from abstract
16895 interface types: No_Predefined_Prims is used to avoid the derivation
16896 of predefined primitives from the interface, and Predefined
16897 Prims_Only is used to complete the derivation predefined primitives
16898 in case of private tagged types implementing interfaces.
16899 Fix typo in comments
16900 (Find_Interface_In_Descendant): Protect the frontend against
16901 wrong code with large circularity chains.
16902 (Is_Private_Overriding): Add support for entities overriding interface
16903 subprograms. The test failed because Entities associated with overriden
16904 interface subprograms are always marked as hidden (and used to build
16905 the secondary dispatch table); in this case the overriden entity is
16906 available through the field abstract_interface_alias (cf. override_
16907 dispatching_operation)
16908 (Access_Definition): Set the scope of the type to Current_Scope for the
16909 case of a function with an anonymous access result type.
16910 (Access_Subprogram_Declaration): Handle creation of the type entity for
16911 an access-to-function type with an anonymous access result.
16912 (Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition
16913 in handling for N_Access_Function_Definition.
16914 (Analyze_Subtype_Declaration): Modify the text of error message.
16915 (Derived_Type_Declaration): Modify the text of error message.
16916 (Process_Subtype): Modify the text of error message plus cleanup
16917 of one redundant error message.
16918 (Analyze_Component_Declaration): Code cleanup.
16919 (Analyze_Object_Declaration): Code cleanup.
16920 (Analyze_Subtype_Declaration): Propagate the null-exclusion
16921 attribute in case of access types. Code cleanup.
16922 (Array_Type_Declaration): Code cleanup.
16923 (Process_Discriminants): Create the new null-excluding itype
16924 if required. Code cleanup.
16925 (Process_Subtype): Create the new null-excluding itype if
16926 required. Code cleanup.
16927 (Build_Derived_Record_Type): Code cleanup to avoid calling
16928 twice the subprogram derive_subprograms in case of private
16929 types that implement interfaces. In this particular case the
16930 subprogram Complete_Subprograms_Derivation already does the
16931 job associated with the second call.
16933 * exp_strm.adb (Build_Elementary_Input_Call): Add an explicit
16934 conversion to the full view when generating an operation for a
16935 discriminant whose type may currently be private.
16937 2005-09-01 Ed Schonberg <schonberg@adacore.com>
16938 Javier Miranda <miranda@adacore.com>
16940 * sem_ch4.adb (Transform_Object_Operation): In a context off the form
16941 V (Obj.F), the rewriting does not involve the indexed component, but
16942 only the selected component itself.
16943 Do not apply the transformation if the analyzed node is an actual of a
16944 call to another subprogram.
16945 (Complete_Object_Operation): Retain the entity of the
16946 dispatching operation in the selector of the rewritten node. The
16947 entity will be used in the expansion of dispatching selects.
16948 (Analyze_One_Call): Improve location of the error message associated
16950 (Analyze_Selected_Component): No need to resolve prefix when it is a
16951 function call, resolution is done when parent node is resolved, as
16953 (Analyze_One_Call): Add a flag to suppress analysis of the first actual,
16954 when attempting to resolve a call transformed from its object notation.
16955 (Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
16956 of the argument list for each interpretation of the operation.
16957 (Try_Object_Operation): The designated type of an access parameter may
16958 be an incomplete type obtained through a limited_with clause, in which
16959 case the primitive operations of the type are retrieved from its full
16961 (Analyze_Call): If this is an indirect call, and the return type of the
16962 access_to_subprogram is incomplete, use its full view if available.
16964 2005-09-01 Javier Miranda <miranda@adacore.com>
16965 Gary Dismukes <dismukes@adacore.com>
16967 * sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
16968 access types the null-exclusion and access-to-constant attributes must
16970 (Analyze_Return_Statement): When the result type is an anonymous access
16971 type, apply a conversion of the return expression to the access type
16972 to ensure that appropriate accessibility checks are performed.
16973 (Analyze_Return_Type): For the case of an anonymous access result type,
16974 generate the Itype and set Is_Local_Anonymous_Access on the type.
16975 Add ??? placeholder for check to disallow returning a limited object
16976 in Ada 2005 unless it's an aggregate or a result of a function call.
16977 Change calls from Subtype_Mark to Result_Definition.
16978 (Analyze_Subprogram_Body): Change formal Subtype_Mark to
16979 Result_Definition in call to Make_Function_Specification.
16980 (Build_Body_To_Inline): Change Set_Subtype_Mark to
16981 Set_Result_Definition.
16982 (Make_Inequality_Operator): Change formal Subtype_Mark to
16983 Result_Definition in call to Make_Function_Specification.
16984 (Process_Formals): Create the new null-excluding itype if required.
16985 (New_Overloaded_Entity): For an entity overriding an interface primitive
16986 check if the entity also covers other abstract subprograms in the same
16987 scope. This is required to handle the general case, that is, overriding
16988 other interface primitives and overriding abstract subprograms inherited
16989 from some abstract ancestor type.
16990 (New_Overloaded_Entity): For an overriding entity that comes from
16991 source, note the operation that it overrides.
16992 (Check_Conformance, Type_Conformant): Addition of one new formal
16993 to skip controlling formals in the analysis. This is used to
16994 handle overloading of abstract interfaces.
16995 (Base_Types_Match): Add missing case for types imported from
16996 limited-with clauses
16997 (New_Overloaded_Entity): Add barrier to protect the use of
16998 the "alias" attribute.
17000 2005-09-01 Ed Schonberg <schonberg@adacore.com>
17002 * sem_ch8.adb (Analyze_Renamed_Entry): For a renaming_as_declaration,
17003 verify that the procedure and the entry are mode conformant.
17004 (Analyze_Subprogram_Renaming): Emit a warning if an operator is renamed
17005 as a different operator, which is often a cut-and-paste error.
17007 2005-09-01 Javier Miranda <miranda@adacore.com>
17008 Ed Schonberg <schonberg@adacore.com>
17010 * sem_disp.adb (Check_Controlling_Formals): Anonymous access types
17011 used in controlling parameters exclude null because it is necessary to
17012 read the tag to dispatch, and null has no tag.
17013 (Override_Dispatching_Operation): If the previous operation is inherited
17014 from an interface, it becomes hidden and does not participate in later

17018 Ed Schonberg <schonberg@adacore.com>
17019 Gary Dismukes <dismukes@adacore.com>
17021 * sem_res.adb (Resolve_Membership_Op): In case of the membership test
17022 "Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
17023 the expander will generate the corresponding run-time check to evaluate
17025 (Resolve_Call): Check for legal type of procedure name or prefix that
17026 appears as a trigger in a triggering alternative.
17027 (Valid_Conversion): If expression is ambiguous and the context involves
17028 an extension of System, remove System.Address interpretations.
17029 (Resolve_Qualified_Expression): Reject the case of a specific-type
17030 qualification applied to a class-wide argument. Enhance comment
17031 to explain checking of Original_Node.
17032 (Resolve_Type_Conversion): The location of the error message was not
17033 general enough to handle the general case and hence it has been removed.
17034 In addition, this patch improves the text of the message.
17035 (Resolve_Type_Conversion): Add missing support for access to interface
17037 (Resolve_Type_Conversion): If the target is a class-wide interface type,
17038 do not expand if the expression is the actual in a call, because proper
17039 expansion will take place when the call itself is expanded.
17040 (Resolve_Allocator): If the context is an unchecked conversion, the
17041 allocator inherits its storage pool, if any, from the target type of
17044 2005-09-01 Ed Schonberg <schonberg@adacore.com>
17045 Javier Miranda <miranda@adacore.com>
17047 * sem_type.adb (Add_One_Interp): If a candidate operation is an
17048 inherited interface operation that has an implementation, use the
17049 implementation to avoid spurious ambiguities.
17050 (Interface_Present_In_Ancestor): In case of concurrent types we can't
17051 use the Corresponding_Record_Typ attribute to look for the interface
17052 because it is set by the expander (and hence it is not always
17053 available). For this reason we traverse the list of interfaces
17054 (available in the parent of the concurrent type).
17055 (Interface_Present_In_Ancestor): Handle entities from the limited view
17057 2005-09-01 Ed Schonberg <schonberg@adacore.com>
17059 * sem_util.ads, sem_util.adb (Gather_Components): Omit interface tags
17060 from the list of required components.
17061 (Is_Controlling_Limited_Procedure): Determine whether an entity is a
17062 primitive procedure of a limited interface with a controlling first
17064 (Is_Renamed_Entry): Determine whether an entry is a procedure renaming
17066 (Safe_To_Capture_Value): A value (such as non_null) is not safe to
17067 capture if it is generated in the second operand of a short-circuit
17069 Do not capture values for variables with address clauses.
17070 (Is_Object_Reference): Treat a function call as an object reference only
17071 if its type is not Standard_Void_Type.
17073 2005-09-01 Ed Schonberg <schonberg@adacore.com>
17075 * sem_warn.adb (Warn_On_Known_Condition): Refine warning when applied
17076 to a variable that is statically known to be constant.

17079 Robert Dewar <dewar@adacore.com>

17090 Add documentation on environment variable syntax for Expand_Path
17092 * gnat_ugn.texi: Update documentation to include mention of -m switches
17093 Document new treatment of wide characters in max line length
17095 Remove -gnatL/-gnatZ switches, no longer used.
17096 Add note on pragmas Assertion_Policy and Debug_Policy in discussion
17099 * gnat_rm.texi: Add doc for two argument form of pragma
17100 Float_Representation.
17101 Add documentation for pragma No_Strict_Aliasing
17102 Add note that explicit component clause overrides pragma Pack.
17103 Add documentation of pragma Debug_Policy

17858 * a-sytaco.ads, a-sytaco.adb (Suspension_Object): These objects are no
17859 longer protected objects. They have been replaced by lower-level
17860 suspension objects made up by a mutex and a condition variable (or
17861 their equivalent given a particular OS) plus some internal data to
17862 reflect the state of the suspension object.
17863 (Initialize, Finalize): Add this initialization procedure for
17864 Suspension_Object, which is a controlled type.
17865 (Finalize): Add the finalization procedure for Suspension_Object,
17866 which is a controlled type.
17868 * a-sytaco-vxworks.ads, a-sytaco-vxworks.adb: Remove this version of
17869 Ada.Synchronous_Task_Control because there is no longer a need for a
17870 VxWorks specific version of this package. Target dependencies
17871 has been moved to System.Task_Primitives.Operations.
17873 * s-osinte-mingw.ads (pCRITICAL_SECTION): Remove this type which is no
17875 (InitializeCriticalSection, EnterCriticalSection,
17876 LeaveCriticalSection, DeleteCriticalSection): Replace the type
17877 pCriticalSection by an anonymous access type so that we avoid problems
17878 of accessibility to local objects.

17884 s-taprop-tru64.adb, s-taprop-lynxos.adb (Elaboration Code): No longer
17885 set the environment task mask here.
17886 (Current_State): Add this function that returns the state of the
17888 (Set_False): Add this procedure that sets the state of the suspension
17890 (Set_True): Add this procedure that sets the state of the suspension
17891 object to True, releasing the task that was suspended, if any.
17892 (Suspend_Until_True): Add this procedure that blocks the calling task
17893 until the state of the object is True. Program_Error is raised if
17894 another task is already waiting on that suspension object.
17895 (Initialize): Add this procedure for initializing the suspension
17896 object. It initializes the mutex and the condition variable which are
17897 used for synchronization and queuing, and it sets the internal state
17899 (Finalize): Add this procedure for finalizing the suspension object,
17900 destroying the mutex and the condition variable.

17905 s-taspri-tru64.ads, s-taspri-lynxos.ads (Suspension_Object): New object
17906 which provides a low-level abstraction (using operating system
17907 primitives) for Ada.Synchronous_Task_Control.
17908 This object is made up by a mutex (for ensuring mutual exclusion), a
17909 condition variable (for queuing threads until the condition is
17910 signaled), a Boolean (State) indicating whether the object is open,
17911 and a Boolean (Waiting) reflecting whether there is a task already
17912 suspended on this object.

18105 * exp_ch5.adb (Expand_N_Return_Statement): When a function's result
18106 type is a class-wide type, emit a run-time check that the accessibility

18177 type derivation of private tagged types implementing interfaces.
18178 In this case some interface primitives may have been overriden

18268 * i-cpp.ads, i-cpp.adb:
18269 This package has been left available for compatibility with previous
18270 versions of the frontend. As part of the new layout this is now a

18324 access to subprograms must be recursive.
18325 (Is_Unchecked_Conversion): Improve the test that recognizes
18326 instantiations of Unchecked_Conversion, and allows them in bodies that
18327 are to be inlined by the front-end. When the body comes from an
18328 instantiation, a reference to Unchecked_Conversion will be an
18329 Expanded_Name, even though the body has not been analyzed yet.

18350 object or component (that is, when Is_Local_Anonymous_Access is true).
18351 Prevent the special checks for conversions of access discriminants in
18352 the case where the discriminant belongs to a nonlimited type, since
18353 such discriminants have their accessibility level defined in the same
18354 way as a normal component of an anonymous access type.
18355 (Resolve_Allocator): When an allocator's designated type is a class-wide
18356 type, check that the accessibility level of type given in the
18357 allocator's expression or subtype indication is not statically deeper

18377 (Resolve_Comparison_Op, Resolve_Equality_Op, Resolve_Boolean_Op): Defer
18378 check on possible violation of restriction No_Direct_Boolean_Operators
18379 until after expansion of operands, to prevent spurious errors when

19406 of Name_Generic_Dispatching_Constructor.
19408 * Makefile.rtl: Add a-tgdico.ads to the list of library units (new Ada

20151 uses of the Access_Disp_Table attribute to reference the first dispatch
20152 table associated with a tagged type. As
20153 part of the implementation of abstract interface types,

20155 tables (rather than a single dispatch table).
20156 Similarly, upgrade all the references to Tag_Component by the
20157 new attribute First_Tag_Component.

20172 determine the amount of data to be copied.
20174 * par.adb (P_Interface_Type_Definition): New subprogram that parses the

20202 (Task_Body_Procedure): Removed.
20203 (Set_Task_Body_Procedure): Removed.
20204 These subprogram have been removed because the attribute
20205 Task_Body_Procedure has been moved to the corresponding task type
20206 or task subtype entity to leave a field free to store the list
20207 of interfaces implemented by a task (for AI-345)

20272 expression to the type of the object when the object is constant.
20273 Reverse defer_debug_incomplete_list before traversing it, so that trees
20274 are processed in the order at which they were added to the list. This
20275 order is important when using the stabs debug format.
20276 If we are deferring the output of debug information, also defer this
20277 output for a function return type.
20278 When adding fields to a record, prevent emitting debug information

20319 N_Qualified_Expression.
20321 * sem_ch3.adb (Derived_Type_Declaration): New predicate
20322 Comes_From_Generic, to recognize accurately that the parent type in a
20323 derived type declaration can be traced back to a formal type, because
20324 it is one or is derived from one, or because its completion is derived
20326 (Constrain_Component_Type): If component comes from source and has no
20327 explicit constraint, no need to constrain in in a subtype of the
20329 (Constrain_Access, Constrain_Array): Allow itypes to be delayed.

20368 improving the quality of code that depends on this test.
20370 * exp_util.adb (Kill_Dead_Code): For a package declaration, iterate
20371 over both visible and private declarations to remove them from tree,

20380 2005-03-15 Ed Schonberg <schonberg@adacore.com>
20382 * exp_ch7.adb (Convert_View): Use base types of underlying types when
20383 determining whether an unchecked conversion is needed for the argument
20384 of an initialization call.
20386 2005-03-15 Ed Schonberg <schonberg@adacore.com>
20388 * exp_intr.adb (Expand_Unc_Conversion): As a target type, use the type
20389 that appears in the instantiation rather than the internal subtype
20390 generated in the wrapper package, to avoid anomalies in gigi when the
20391 target is derived from a private type whose full view is an access type.
20393 2005-03-15 Robert Dewar <dewar@adacore.com>
20395 * exp_smem.adb, sem_attr.adb: Remove OK_For_Stream flag, not used,
20397 Add documentation to replace the use of this flag
20398 Fix kludge for Maximum_Alignment on x86 so that it does not apply to
20401 2005-03-15 Thomas Quinot <quinot@adacore.com>
20403 * exp_tss.ads, exp_tss.adb (Find_Inherited_TSS): New subprogram, moved
20404 here from exp_attr so it can be shared between exp_attr and exp_dist.
20405 (TSS_Names): Renamed from OK_TSS_Names. This array contains the list of
20406 all TSS names, not a subset thereof, and the previous name introduced
20407 an unnecessarily confusion that a distinction might exist between
20408 "OK" TSS names and some "not OK" TSS names.
20410 2005-03-15 Doug Rupp <rupp@adacore.com>
20412 * gnatchop.adb (Locate_Executable): Normalize the possibly VMS style
20415 2005-03-15 Pascal Obry <obry@adacore.com>
20416 Eric Botcazou <ebotcazou@adacore.com>
20420 * init.c (__gnat_initialize): Do not call __gnat_install_SEH_handler()
20421 when IN_RTS. This is to work around a bootstrap path problem.
20423 * misc.c (gnat_parse_file): Create a SEH (Structured Exception Handler)
20424 table and pass it to __gnat_install_SEH_handler().
20425 (gnat_handle_option): Accept OPT_fRTS_, not OPT_fRTS.
20427 * lang.opt: Fix specification of -fRTS=.
20429 2005-03-15 Doug Rupp <rupp@adacore.com>
20430 Bernard Banner <banner@adacore.com>
20431 Vincent Celier <celier@adacore.com>
20432 Arnaud Charlet <charlet@adacore.com>
20435 This change works fine when gnatlib is built from the gcc directory,
20436 but does not work when using the libada Makefile, since GCC_FOR_TARGET
20437 is not passed to ada/Makefile.in, so more work is needed by a
20438 Makefile/configure expert.
20440 * Makefile.in(gnatlib): Use $(GCC_FOR_TARGET) for compiling library.
20441 set GMEM_LIB on ia64 linux to add optional support for gnatmem.
20442 Setup gnatlink switch -M for x86_64 linux, as it is already setup
20444 (gnatlib-shared-default): Use GNATLIBCFLAGS as well.
20445 Run ranlib on libgccprefix.a
20446 Define PREFIX_OBJS for Darwin, to build libgccprefix.
20447 (ADA_INCLUDE_SRCS): Split Ada packages.
20449 2005-03-15 Robert Dewar <dewar@adacore.com>
20451 * Make-lang.in: Add g-utf_32 unit for gnat and gnatbind
20453 * impunit.adb: Add GNAT.UTF_32
20455 * scng.adb: Use gnat.utf_32 instead of widechar for utf_32 stuff
20457 * widechar.ads, widechar.adb: Remove redundant UTF-32 tables (scng
20458 now uses GNAT.UTF_32).
20460 * g-utf_32.ads, g-utf_32.adb: This is a new unit with full
20461 capabilities for categorizing characters using Unicode categories
20463 2005-03-15 Ed Schonberg <schonberg@adacore.com>
20465 * sem_ch10.adb (Build_Ancestor_Name): If the ancestor is an
20466 instantiation that has been rewritten as a package body, retrieve spec
20467 to generate proper name for implicit_with_clause.
20468 (Install_Parents): Recognize a parent that is an instantiation but has
20469 been rewritten as a package declaration during analysis.
20471 2005-03-15 Javier Miranda <miranda@adacore.com>
20472 Ed Schonberg <schonberg@adacore.com>
20474 * sem_ch12.adb (Instantiate_Object): If the analysis of the actual
20475 parameter reported some error we immediately return. This improves the
20476 behaviour of the frontend in case of errors.
20477 (Install_Parent, Remove_Parent): Introduce new flag
20478 Parent_Unit_Visible, to preserve the proper visibility of the ultimate
20479 ancestor of a generic child unit, when the child is being instantiated.
20480 (Inline_Instance_Body): If we are compiling the private
20481 part or the body of a child unit, restore the proper visibility of the
20482 parents after compiling the instance body.
20484 2005-03-15 Ed Schonberg <schonberg@adacore.com>
20485 Javier Miranda <miranda@adacore.com>
20488 * sem_util.adb (Get_Task_Body_Procedure): Type may be the completion
20489 of a private type, in which case it is underlying_type that denotes
20490 the proper task. Also modified to use the new entity attribute
20491 that is directly available in the task type and task subtype entities
20492 (Build_Actual_Subtype_Of_Component): Handle properly multidimensional
20493 arrays when other dimensions than the first are constrained by
20494 discriminants of an enclosing record.
20495 (Insert_Explicit_Dereference): If the prefix is an indexed component or
20496 a combination of indexed and selected components, find ultimate entity
20497 and generate the appropriate reference for it, to suppress spurious
20499 (Note_Possible_Modification): If an entity name has no entity, return.
20500 (Is_Variable): A function call never denotes a variable.
20501 (Requires_Transient_Scope): For record types, recurse only on
20502 components, not on internal subtypes that may have been generated for
20503 constrained components.
20505 2005-03-15 Ed Schonberg <schonberg@adacore.com>
20507 * sem_ch4.adb (Analyze_Concatenation): Do not consider operators marked
20508 Eliminated as candidates for resolution. Both efficient, and avoids
20509 anomalies with operators declared in deleted code.
20510 (Process_Implicit_Dereference_Prefix): Use this procedure whenever
20511 expansion is disabled (as when compiling a generic) to prevent spurious
20512 warnings on prefixes of selected components.
20514 2005-03-15 Ed Schonberg <schonberg@adacore.com>
20516 * sem_ch6.adb (Is_Private_Declaration): Verify that the declaration is
20517 attached to a list before checking whether it appears in the private
20518 declarations of the current package.
20519 (Make_Inequality_Operator): Insert declaration in proper declarative
20520 list rather than just setting the Parent field, so that
20521 Is_Private_Declaration can handle it properly.
20523 2005-03-15 Ed Schonberg <schonberg@adacore.com>
20525 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic, if this is
20526 a renaming a body, check that the renamed subprogram in not intrinsic.
20527 (Find_Direct_Name): If several use_visible entities hide
20528 each other, and the context is a predefined file compiled through
20529 rtsfind, keep only the entity that comes from a predefined file.
20531 2005-03-15 Geert Bosch <bosch@adacore.com>
20533 * s-fatgen.adb (Valid): Extend special exceptions to account for long
20534 long float padding to also cover AMD64 and IA64.
20536 2005-03-15 Gary Dismukes <dismukes@adacore.com>
20538 * s-imgwch.adb: Add with and use of Interfaces.
20539 (Img_Wide_Character): Change type of Val to Unsigned_16.

20861 (Resolve_Slice): If the prefix is an access to an unconstrained array,
20862 compute the actual subtype of the designated object to impose the proper
20864 (Resolve_Selected_Component): Do not insert an access check if the
20865 prefix is an access type: such a node is expanded into an explicit
20866 dereference, on which the access check is performed anyway. Removes
20867 expensive duplicate checks.
20868 (Resolve_Call): Use new flag Is_Obsolescent and field
20869 Obsolescent_Warning so that pragma Obsolescent works on library
20871 Add support for wide wide character type
20872 (Resolve_Allocator): Replace the error message on wrong null-exclusion
20873 value by a warning message.
20874 (Resolve_Type_Conversion): If the mixed-mode expression is interpreted
20875 as fixed-point, and one of the operands is non-static and universal, it
20876 can only be an illegal exponentiation operation, in which case there is
20877 no real value to retrieve.
20879 * exp_strm.adb: Add support for wide wide character type
20880 (Build_Elementary_Input_Call): Compute the size of the stream element by

20906 Corresponding_ Formal_Spec and simplify condition.
20907 (Use_One_Package): Check that scope of homonym of identifier is defined,
20908 before checking whether it is a wrapper package.

20918 "not in" for test of N_Formal_Subprogram_Declaration (which is now a
20920 (Unit_Declaration_Node): Ditto.
20921 (Is_Variable_Prefix): For the case of an indexed component whose prefix
20922 has a packed array type, the prefix has been rewritten into a type
20923 conversion. Determine variable-ness from the converted expression.
20924 Handle wide wide character cases.

20928 * stringt.ads, stringt.adb: Handle full UTF-32 range.
20929 Remove ["0A"] from comment, since it can look like a line terminator.
20930 Currently we don't permit this, but this is under discussion by the
20931 ARG, and it is easy enough to use a different example.
20933 * s-wchcon.ads, s-wchcnv.ads, s-wchcnv.adb: Add new subprograms for
20934 handling UTF-32 encoding for wide wide character.
20935 Implement new brackets coding ["hhhhhhhh"]

20950 Rcheck subprograms.
20952 * checks.adb (Check_Null_Not_Allowed): Replace the error message on
20953 wrong null-exclusion value by a warning message.
20954 (Enable_Range_Check): Do range check if the prefix is an
20955 explicit dereference whose designated object is an unconstrained array.
20956 Current algorithm for removing duplicate checks is over-eager in this

20984 * exp_disp.ads, exp_disp.adb (Make_DT): Generate code that moves the
20985 pointer to the base of the dispatch table.
20986 Minor changes to comments.
20987 (Controlling_Type): New function for determining the tagged type
20988 associated with a tagged primitive subprogram.
20989 (Expand_Dispatching_Call): Add support for a controlling actual that is

20992 * i-cpp.ads, i-cpp.adb, a-tags.ads, a-tags.adb: Update documentation
20993 describing the new layout.
20994 (Dispatch_Table): The expander computes the actual array size, allocates
20995 the Dispatch_Table record accordingly, and generates code that displaces
20996 the base of the record after the Typeinfo_Ptr component. The access to
20997 these components is done by means of local functions.
20998 (Offset_To_Top): New function.
20999 (Typeinfo_Ptr): New function.
21000 (Get_TSD): Modified to access the new position of the TSD.

21011 N_Formal_Subtype_Declaration (which is now a subtype).
21012 (Analyze_Formal_Subprogram): Add handling for
21013 N_Formal_Abstract_Subprogram, marking the formal as abstract and
21014 dispatching, setting the controlling status of the formal parameters
21015 and result, and issuing an error if there is no controlling type for
21016 the formal subprogram.
21017 (Instantiate_Formal_Subprogram): Rather than setting Corresponding_Spec,
21018 which is an unclean use of that field, we set the new field
21019 Corresponding_Formal_Spec to make the formal subprogram available to
21020 processing in Analyze_Subprogram_Declaration.
21021 (Analyze_Formal_{Discrete, Decimal_Fixed_Point, Fixed_Point,
21022 Floating_Point, Modular_Integer, Signed_Integer}_Type: Make formal type

21027 abstract formal subprograms in error check for functions returning
21028 abstract types. Set scope of new designator for

21031 (Analyze_Subprogram_Body): Warn on inlining bodies with nested
21032 subprogram only if inner one comes from source.
21033 (Analyze_Function_Call): If the call is given in object notation, the
21034 analysis of the name rewrites the node and analyzes it with the proper
21035 argument list. After analyzing the name, if the call has been rewritten
21036 and the result type is set, no further analysis is needed.
21037 (Analyze_Return_Type): Subsidiary to Process_Formals: analyze subtype
21038 mark in function specification, in a context where the formals are
21039 visible and hide outer homographs.
21041 * sem_disp.adb (Check_Controlling_Type): Relax the check for same scope
21042 as the tagged type for the cases of abstract formal subprograms and
21043 renamings of those. Clean up spec comments.
21044 (Check_Dispatching_Context): Add error message to indicate "abstract
21045 procedure", covering the case of a call to a formal abstract procedure
21046 that has statically tagged operands.
21047 (Check_Dispatching_Call): Check for the case of an actual given by
21048 a tag-indeterminate function call whose type is an ancestor of the
21049 containing call's associated tagged type. This situation can occur
21050 for inherited primitives with function defaults. In this case we
21051 use the tagged type's tag directly as the controlling argument for
21053 (Expand_Call): Name change on call to Expand_Dispatch_Call.
21055 * sprint.adb (Sprint_Node_Actual): Split
21056 N_Formal_Subprogram_Declaration into two alternatives for the new

21133 on the field if Pragma Component_Alignment (Storage_Unit).
21134 (gnat_to_gnu_entity, case object): Do not treat a renaming that has
21135 side-effects as if it were a constant; also make SAVE_EXPR to protect

21153 2005-02-09 Ed Schonberg <schonberg@adacore.com>
21155 * exp_aggr.adb (Gen_Assign): If the expression is an aggregate for a
21156 component of an array of arrays in an assignment context, and the
21157 aggregate has component associations that require sliding on
21158 assignment, force reanalysis of the aggregate to generate a temporary
21159 before the assignment.
21160 (Must_Slide): Make global to the package, for use in Gen_Assign.
21162 2005-02-09 Ed Schonberg <schonberg@adacore.com>
21164 * exp_ch4.adb (Expand_Composite_Equality): If a component is an
21165 unchecked union with no inferable discriminants, return a
21166 Raise_Program_Error node, rather than inserting it at the point the
21168 (Expand_Record_Equality, Component_Equality): Handle properly the case
21169 where some subcomponent is an unchecked union whose generated equality
21170 code raises program error.

21178 Arnaud Charlet <charlet@adacore.com>
21180 * init.c (__gnat_initialize): Add a new parameter eh which contains the
21181 address of the exception registration. The Win32 version of this
21182 routine calls __gnat_install_SEH_handler() to initialize the SEH
21183 (Structured Exception Handling) handler.
21184 (__gnat_error_handler) [Win32]: Removed. Not needed as we use
21185 SEH (Structured Exception Handling) now.
21186 (__gnat_install_handler) [Win32]: Nothing to do now as we use SEH.
21187 (__gnat_initialize for ppc-vxworks): Adjust comments and the
21188 preprocessor condition protecting the call to the extra eh setup
21189 subprogram, which is only available for the ppc target.

21203 Update copyright notice.
21205 * s-tassta.adb (Task_Wrapper): Declare the exception registration

21235 2005-02-09 Vincent Celier <celier@adacore.com>
21237 * prj-makr.adb (Process_Directory): Put file name in canonical case
21238 before matching against the patterns.
21239 If gnatname has been invoked as <prefix>-gnatname
21240 then invoke the compiler as <prefix>-gcc, not just "gcc".
21242 2005-02-09 Ed Schonberg <schonberg@adacore.com>
21244 * sem_ch4.adb (Analyze_Selected_Component): Create Actual_Subtype even
21245 with expansion disabled. The actual subtype is needed among other
21246 places when the selected component appears in the context of a loop
21247 bound, and denotes a packed array.
21248 (Operator_Check): Always use the first subtype in the
21249 error message, to avoid the appearance of internal base types.
21250 (Transform_Object_Operation): Copy each actual in full
21251 to the parameter associations of the constructed call, rather than
21252 using the shallow copy mechanism of New_Copy_List. This ensures that
21253 the chaining of named associations is done properly.
21254 (Complete_Object_Operation): Rewrite node, rather than
21255 replacing it, so that we can trace back to the original selected
21258 * sem_elab.adb (Set_Elaboration_Constraint): For initialization calls,
21259 and calls that use object notation, if the called function is not
21260 declared in a withed unit, place the elaboration constraint on the
21261 unit in the context that makes the function accessible.
21262 (Check_Elab_Subtype_Declaration): Check whether a subtype declaration
21263 imposes an elaboration constraint between two packages.
21265 2005-02-09 Ed Schonberg <schonberg@adacore.com>
21267 * sem_ch7.adb (Uninstall_Declarations): Exchange full and private
21268 views of a private type after handling its private dependents, to
21269 maintain proper stack discipline between entry and exit from the

21290 Slight fix to documentation of -gnaty with no parameters
21292 * xr_tabls.ads: Add ??? comment for missing overall comment
21294 * xsinfo.adb: Make default file name be sinfo.h, since this is what
21295 we now use by default.
21297 * xsnames.adb: Adjust end of file test to look for five space followed
21298 by '#' instead of six spaces. The format of xsnames.adb was modified
21299 in the last update.
21301 * a-numeri.ads: Add reference to AI-388 for greek letter pi
21304 * clean.adb: Minor reformatting.
21306 * gnat1drv.adb, gnatfind.adb, gnatlink.adb, gnatmem.adb,
21307 gnatname.adb: Minor reformatting
21308 Add 2005 to copyright output when utility is run
21310 * csets.adb: Eliminate obsolete comment
21312 * debug.adb, g-socket.ads, i-cobol.adb: Minor reformatting throughout
21315 * sem_eval.ads (Eval_Integer_Literal): Do not inline this, not useful.
21317 2005-02-09 Sergey Rybin <rybin@adacore.com>
21319 * gnat_ugn.texi: Add to the gnatpp section the paragraph describing
21320 the difference between compact and incompact layout and add the record
21321 representation clause to the example illustrating different layouts.
21322 Add the description of '-A5' gnatpp option ("align 'AT' keywords in
21323 component clauses").
21325 2005-02-09 Florian Villoing <villoing@adacore.com>
21327 * gnat_ugn.texi: Fix typos.
21328 Use @command to display 'gcc', 'gnatbind', etc. insted of @code or
21330 Make proper use of @ref, @xref and @pxref to avoid duplication of "see"

21629 * decl.c (compatible_signatures_p): New function. The intended purpose
21630 is to check if two function signatures for a call-site and a callee are
21631 compatible enough for the call to be valid. The underlying purpose is
21632 to check if a call to a mapped builtin is using the right interface.
21633 The current code actually does not check antyhing - this a placeholder

21685 structure of GARLIC and PolyORB RPC receivers.
21686 (Add_Receiving_Stubs_To_Declarations): Make this subprogram
21688 Simplify elaboration code for RCI packages.
21690 * s-parint.ads, s-parint.adb, rtsfind.ads: Reorganise RPC receiver

21800 note that it applies to obsolete GNAT features, which was previously
21801 omitted. Second we contrast the behavior with that of the new
21802 Ada 2005 AI-368 restriction No_Obsolescent_Features.
21803 Preliminary rewriting of GNAT & libraries chapter in order to take
21804 into account default project locations & new project manager

22035 "no bitfield creation", to be used by make_aligning_type. Don't
22036 restrict bitfield creation to !ADDRESSABLE any more, as some BLKmode
22037 fields claimed addressable still have to be bitfields. Use
22038 value_factor_p instead of a raw binop construction to check for the
22039 position's alignment.

22046 Ed Schonberg <schonberg@adacore.com>
22048 * exp_ch4.adb (Expand_N_Indexed_Component): For an indexed component
22049 with an implicit dereference as its prefix, use
22050 Insert_Explicit_Dereference instead of merely rewriting the prefix into

22052 prefix is generated, if appropriate.
22054 * sem_util.adb (Insert_Explicit_Dereference): When an implicit
22055 dereference is rewritten to an explicit one, generate a reference to
22056 the entity denoted by its prefix using the original prefix node, so

22058 access value, if appropriate.
22060 * sem_warn.adb (Output_Unreferenced_Messages): Do not abstain from
22061 emitting 'assigned but never read' warning on a variable on the basis

22075 an external name, to be handled by the back end.
22077 * sem_prag.adb (Process_Import_Or_Interface): Do not check validity of
22078 subprogram which is Imported with convention Intrinsic if an
22079 External_Name argument is specified.
22080 (Process_Import_Or_Interface): Properly diagnose link name argument.
22081 (Inlining_Not_Possible): New name for Cannot_Inline, to avoid confusion

22106 PolyORB_Support.Build_Stub_Type): New subrograms containing the
22107 PCS-specific part of Add_Stub_Type.

22137 * sem_ch9.adb (Analyze_Accept_Statement): Reset the Is_Referenced flag
22138 and the Has_Pragma_Unreferenced flag for each formal before analyzing
22139 the body, to ensure that warnings are properly emitted for each accept
22140 statement of a given task entry.
22142 2004-12-07 Vasiliy Fofanov <fofanov@adacore.com>
22144 * Makefile.in: Add support for foreign threads on VMS.

22162 (Remove_Next_Debug): Same fix
22164 * nlists.ads: Correct bad comments for Prev and Prev_Non_Pragma (we do
22165 maintain back pointers now, though we did not used to, and comments
22167 (Prepend): Remove pragma Inline.
22168 (Remove_Next): Same cleanup
22170 2004-12-07 Thomas Quinot <quinot@adacore.com>
22172 * sem_ch4.adb (Process_Implicit_Dereference_Prefix): New subprogram
22173 used to record an implicit dereference as a read operation on its
22174 prefix when operating under -gnatc. Necessary to avoid spurious
22175 'variable assigned but never read' warnings in that mode.
22176 (Process_Indexed_Component, Analyze_Selected_Component): When the prefix
22177 is a non-overloaded implicit dereference, call the above subprogram to
22178 ensure proper recording of references.
22180 2004-12-07 Gary Dismukes <dismukes@adacore.com>
22182 * sem_ch5.adb (One_Bound): Remove call to Resolve, as the bound needs
22183 to be resolved later as part of Analyze_Iteration_Scheme's call to

22230 2004-12-07 Vincent Celier <celier@adacore.com>
22232 * vms_data.ads: Correct GNAT METRIC qualifiers: -I-, -Idir and
22233 -gnatec= are not direct switches of gnatmetric. Changed -eis to -eps
22234 and -eit to -ept. Added qualifier
22235 /ELEMENT_METRICS=CONSTRUCT_NESTING_MAX for new switch -ec.
22237 2004-11-27 Andreas Schwab <schwab@suse.de>
22239 * Make-lang.in (ada/trans.o): Depend on $(EXPR_H).
22241 2004-11-25 Arnaud Charlet <charlet@adacore.com>
22243 * g-socthi-mingw.ads, g-socthi-vms.ads: Remove C_Read and C_Write from
22244 internal implementation unit GNAT.Sockets.Thin,
22245 as their usage for sockets is non-portable (using the read and write
22246 functions from the system runtime library is fine on UNIX but won't
22247 work under Windows).

22251 2004-11-25 Arnaud Charlet <charlet@adacore.com>

22300 (Setup_Exception): Do nothing in the GNAT SJLJ case.
22302 * gigi.h (others_decl, all_others_decl): New decls representing the
22303 new Others_Value and All_Others_Value objects.
22304 (struct attrib): Rename "arg" component as "args", since GCC expects a
22305 list of arguments in there.
22307 * raise.c (GNAT_OTHERS, GNAT_ALL_OTHERS): Are now the address of the
22308 corresponding objects exported by a-exexpr, instead of hardcoded dummy
22311 * trans.c (Exception_Handler_to_gnu_zcx): Use the address of
22312 others_decl and all_others_decl instead of hardcoded dummy addresses
22313 to represent "others" and "all others" choices, which is cleaner and
22314 more flexible with respect to the possible eh pointer encoding policies.
22316 * utils.c (init_gigi_decls): Initialize others_decl and all_others_decl.
22317 (process_attributes): Account for the naming change of the "args"
22318 attribute list entry component.
22320 * decl.c (build_attr_list): Rename into prepend_attributes to allow
22321 cumulating attributes for different entities into a single list.
22322 (gnat_to_gnu_entity): Use prepend_attributes to build the list of
22323 attributes for the current entity and propagate first subtype
22324 attributes to other subtypes.
22325 <E_Procedure>: Attribute arguments are attr->args and not
22326 attr->arg any more.
22327 (build_attr_list): Ditto. Make attr->args a TREE_LIST when there is an
22328 argument provided, as this is what GCC expects. Use NULL_TREE instead
22331 2004-11-18 Robert Dewar <dewar@adacore.com>
22333 * a-stmaco.ads, exp_util.ads, exp_util.adb, i-cpp.ads, i-cpp.adb:
22334 Minor reformatting througout (including new function specs)
22335 Add ??? comments asking for clarification.

22345 procedures factors the common processing for building an RPC receiver
22346 for an RCI package or an RACW type.
22347 Stylistic cleanup: change '/= Empty' to 'Present ()'; move body of
22348 Build_Remote_Subprogram_Proxy_Type into proper alphabetical order.
22349 (Get_PCS_Name): New subprogram. Returns the name of the PCS currently
22351 (Specific_Add_RACW_Features): New subprogram. PCS-specific part of
22353 (Specific_Add_RAST_Features): New subprogram. PCS-specific part of
22355 (Assign_Subprogram_Identifier): New subprogram. Provision for assigning
22356 distribution subprogram identifiers that are either subprogram numbers
22358 (Get_Subprogram_Ids): New subprogram. Retrieve both the numeric and
22359 string distribution identifiers assigned to a given subprogram.
22360 (Get_Subprogram_Id): Reimplement in terms of Get_Subprogram_Ids.
22361 (Add_RAS_Dereference_TSS): Add comments.
22362 (Build_General_Calling_Stubs): Note that the RACW_Type formal parameter
22363 is not referenced yet because it will be used by the PolyORB DSA
22365 (Insert_Partition_Check): Remove fossile code.
22366 (First_RCI_Subprogram_Id): Document this constant.
22367 (Add_RAS_Access_TSS): Correct the setting of the Etype of the
22369 (Get_Pkg_Name_String): Remove subprogram. Usage occurrences are
22370 replaced with calls to Get_Library_Unit_Name_String. Previously there
22371 were several instances of the same code in different locations in the
22372 compiler; this checkin completes the replacement of all of these
22373 instances with calls to a common subprogram.
22374 Minor reformatting.
22376 * sem_dist.adb: Remove comment noting that RPC receiver generation
22377 should be disabled for RACWs that implement RASs.
22378 (Process_Partition_Id): Use new subprogram Get_Library_Unit_Name_String.
22380 * sem_util.ads, sem_util.adb (Has_Stream): New function
22381 (Get_Library_Unit_Name_String): New subprogram to retrieve the fully
22382 qualified name of a library unit into the name buffer.
22383 (Note_Possible_Modification): Generate a reference only
22384 if the context comes from source.
22386 * snames.ads (PCS_Names): New subtype corresponding to names of
22387 supported implementations of the Partition Communication Subsystem
22388 (PCS) (i.e. the runtime library support modules for the distributed
22391 2004-11-18 Robert Dewar <dewar@adacore.com>
22392 Ed Schonberg <schonberg@adacore.com>
22394 * einfo.ads, einfo.adb: Remove Is_Psected flag, no longer used
22395 (Has_Rep_Pragma): New function
22396 (Has_Attribute_Definition_Clause): New function
22397 (Record_Rep_Pragma): Moved here from sem_ch13.adb
22398 (Get_Rep_Pragma): Remove junk kludge for Stream_Convert pragma
22400 * sem_ch13.ads, sem_ch13.adb (Record_Rep_Pragma): Moved to einfo.adb
22402 * exp_prag.adb: (Expand_Pragma_Common_Object): New procedure
22403 (Expand_Pragma_Psect_Object): New procedure
22404 These procedures contain the revised and cleaned up processing for
22405 these two pragmas. This processing was formerly in Sem_Prag, but
22406 is more appropriately moved here. The cleanup involves making sure
22407 that the pragmas are properly attached to the tree, and that no
22408 nodes are improperly shared.
22410 * sem_prag.adb: Move expansion of Common_Object and Psect_Object
22411 pragmas to Exp_Prag, which is more appropriate.
22412 Attach these two pragmas to the Rep_Item chain Use Rep_Item chain to
22413 check for duplicates Remove use of Is_Psected flag, no longer needed.
22414 Use new Make_String_Literal function with string.
22416 * exp_attr.adb (Expand_Fpt_Attribute): The floating-point attributes
22417 that are functions return universal values, that have to be converted
22418 to the context type.
22419 Use new Make_String_Literal function with string.
22420 (Get_Stream_Convert_Pragma): New function, replaces the use of
22421 Get_Rep_Pragma, which had to be kludged to work in this case.
22423 * freeze.adb: Use new Has_Rep_Pragma function
22425 * exp_intr.adb, exp_ch3.adb, sem_attr.adb: Use new Make_String_Literal
22426 function with string.
22427 Use new Has_Rep_Pragma function.
22429 * tbuild.ads, tbuild.adb (Make_String_Literal): New function, takes
22432 2004-11-18 Robert Dewar <dewar@adacore.com>
22434 * errout.ads, errout.adb: (First_Sloc): New function
22436 * par-ch5.adb (P_Condition): Check for redundant parens is now a style
22437 check (-gnatyx) instead of being included as a redundant construct
22440 * sem_ch6.adb: Change name Style_Check_Subprogram_Order to
22441 Style_Check_Order_Subprograms.
22443 * style.ads, styleg.ads, styleg.adb, styleg-c.adb, stylesw.ads,
22444 stylesw.adb: Add Style_Check_Xtra_Parens
22446 * usage.adb: Add line for -gnatyx (check extra parens)
22448 * vms_data.ads: Add entry for STYLE_CHECKS=XTRA_PARENS => -gnatyx
22450 2004-11-18 Ed Schonberg <schonberg@adacore.com>
22451 Robert Dewar <dewar@adacore.com>
22453 * exp_ch4.adb (Expand_N_Selected_Component): If the component is the
22454 discriminant of a constrained subtype, analyze the copy of the
22455 corresponding constraint, because in some cases it may be only
22456 partially analyzed.
22457 Removes long-lived ??? comments.
22459 * exp_ch7.adb (Establish_Transient_Scope): Remove complex code that
22460 handled controlled or secondary-stack expressions within the
22461 iteration_scheme of a loop.
22463 * sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
22464 bounds that may contain functions calls, to prevent memory leaks when
22465 the bound contains a call to a function that uses the secondary stack.
22466 (Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
22467 generate temporaries for loop bounds that might contain function calls
22468 that require secondary stack and/or finalization actions.
22470 * sem_ch4.adb (Analyze_Indexed_Component_Form): If the prefix is a
22471 selected component and the selector is overloadable (not just a
22472 function) treat as function call, Analyze_Call will disambiguate if
22474 (Analyze_Selected_Component): Do not generate an actual subtype for the
22475 selected component if expansion is disabled. The actual subtype is only
22476 needed for constraint checks.
22477 (Analyze_Allocator): If restriction No_Streams is set, then do
22478 not permit objects to be declared of a stream type, or of a
22479 composite type containing a stream.
22481 * restrict.ads: Remove the a-stream entry from Unit_Array, since
22482 No_Streams no longer prohibits with'ing this package.
22484 * sem_ch3.adb (Build_Derived_Record_Type): If the parent type has
22485 discriminants, but the parent base has unknown discriminants, there is
22486 no discriminant constraint to inherit. Such a discrepancy can arise
22487 when the actual for a formal type with unknown discriminants is a
22488 similar private type whose full view has discriminants.
22489 (Analyze_Object_Declaration): If restriction No_Streams is set, then
22490 do not permit objects to be declared of a stream type, or of a
22491 composite type containing a stream.
22493 2004-11-18 Ed Schonberg <schonberg@adacore.com>
22495 * exp_dbug.ads: Update documentation to reflect simpler encoding for
22496 protected operations.
22498 * exp_ch9.adb (Build_Selected_Name): Do not include "PT" suffix in
22499 generated name, it complicates decoding in gdb and hinders debugging
22500 of protected operations.
22501 (Build_Barrier_Function_Specification): Set the Needs_Debug_Info
22502 flag for the protected entry barrier function.
22503 (Build_Protected_Entry_Specification): Set the Needs_Debug_Info
22504 flag for the protected entry function.

22508 * expect.c: Define __unix__ when __APPLE__ is defined.
22510 * Makefile.in: Inform the value of the variable GMEM_LIB in the
22511 Darwin-specific section.
22513 * lang-specs.h: Change the placement of the %1 marker.
22514 Works around the fact that gcc adds -fPIC by default under Darwin.
22516 2004-11-18 Ed Schonberg <schonberg@adacore.com>
22518 * exp_pakd.adb (Convert_To_PAT_Type): After replacing the original
22519 type of the object with the packed array type, set the Analyzed flag
22520 on the object if it is an entity or simple indexed component, to avoid
22521 spurious type errors.
22523 2004-11-18 Gary Dismukes <dismukes@adacore.com>
22525 * gnat1drv.adb, gnatbind.adb, gnatchop.adb, gnatfind.adb, gnatlink.adb,
22526 gnatls.adb, gnatxref.adb, gprep.adb: Output the copyright message on a
22527 separate line from the version message.
22529 2004-11-18 Ed Falis <falis@adacore.com>
22531 * init.c (__gnat_map_signal): map SIGSEGV to Storage_Error for AE653
22533 (init_float): Eliminate initialization of floating point status for
22534 AE653. The instructions have no effect for vThreads.
22536 2004-11-18 Vincent Celier <celier@adacore.com>
22538 * make.adb (Gnatmake): Invoke gnatlink with -shared-libgcc when
22539 gnatbind is invoked with -shared.
22541 2004-11-18 Jose Ruiz <ruiz@adacore.com>
22543 * s-tposen.adb (Lock_Entry): Remove the code for raising Program_Error
22544 for Detect_Blocking which is redundant with the check done within the
22545 procedure Protected_Single_Entry_Call.
22546 (Lock_Read_Only_Entry): Remove the code for raising Program_Error for
22547 Detect_Blocking which is redundant with the check done within the
22548 procedure Protected_Single_Entry_Call.
22550 2004-11-18 Vincent Celier <celier@adacore.com>
22552 * makegpr.adb (Compile): Put the compiling switches (in package
22553 Compiler and on the command line) immediately after "-c", instead of
22554 at the end of the command line invocation of the compiler, when
22555 compiling a non-Ada file.
22556 (Build_Global_Archive): When there is no need to rebuild the archive,
22557 set Global_Archive_Exists, so that the archive is passed to the linker
22560 2004-11-18 Robert Dewar <dewar@adacore.com>
22561 Sergey Rybin <rybin@adacore.com>
22564 Remove extra paren check from list of checks for redundant constructs
22565 Add documentation of new -gnatyx style check (check extra parens)
22566 Remove paragraph about gnatelim debug options.
22568 * gnat_rm.texi: Document that Ada.Streams now forbids creating stream
22569 objects rather than forbidding dependencies on the package Ada.Streams.
22571 * sinfo.ads: Add ??? note that we should document pragmas passed to
22574 * g-expect.ads: Fix a few typos in the comments.
22576 2004-11-09 Joseph S. Myers <joseph@codesourcery.com>
22578 * misc.c (gnat_handle_option): Use %< and %> for quoting in
22581 2004-11-08 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
22583 * a-numaux-x86.adb (Tan): Fix fdivp syntax.
22585 2004-11-07 Andreas Schwab <schwab@suse.de>
22587 * Makefile.in (install-gnatlib): Remove spurious hyphen.
22589 2004-11-02 Andrew Pinski <pinskia@physics.uc.edu>
22592 * Makefile.in (darwin): Set soext to .dylib.
22594 2004-10-26 Vincent Celier <celier@gnat.com>
22595 Thomas Quinot <quinot@act-europe.fr>
22597 * g-socthi-vms.adb, g-socthi-mingw.adb, g-socthi-vxworks.ads:
22598 (C_Writev): Change MSG_Forced_Flags to Constants.MSG_Forced_Flags as
22599 there is no use of GNAT.Sockets.Constants.
22600 Remove remaining pragma Import for C_Write
22601 Remove C_Read and C_Write from internal implementation unit
22602 GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
22603 the read and write functions from the system runtime library is fine
22604 on UNIX but won't work under Windows).
22606 * g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
22607 (Check_Selector): Use C_Recv instead of C_Read.
22608 Selectors are the GNAT.Sockets abstraction to perform a select()
22609 call on a set of descriptors. To allow abortion of an ongoing
22610 select operation, some data is written to a dedicated socket that
22611 is always monitored.
22612 Under Windows, the write and read library functions cannot operate
22613 on sockets, so we need to use send and recv instead, which is portable
22614 across all supported platforms.
22616 * g-socthi.ads: Remove C_Read and C_Write from internal implementation
22617 unit GNAT.Sockets.Thin, as their usage for sockets is non-portable
22618 (using the read and write functions from the system runtime library is
22619 fine on UNIX but won't work under Windows).
22621 2004-10-26 Nicolas Setton <setton@act-europe.fr>
22623 * mlib-tgt-darwin.adb: New file.
22625 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
22626 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
22627 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb,
22628 mlib-tgt-mingw.adb, mlib-tgt-vxworks.adb (Archive_Indexer_Options): New
22631 * Makefile.in: Add support for building shared libraries under Darwin.
22632 (EXTRA_GNATRTL_NONTASKING_OBJS, ppc-vxworks): Add s-vxwexc.o, containing
22633 the low level EH init subprogram to be called from __gnat_initialize.
22635 * mlib-tgt.ads, mlib-tgt.adb (Archive_Indexer_Options): New subprogram,
22636 indicates which options to pass to the archive indexer.
22638 * mlib-utl.adb: Add support for calling ranlib with additional
22639 options. This is needed for instance under Mac OS X.
22640 (Ranlib_Options): New global variable, used to store the potential
22641 options to pass to ranlib.
22642 (Ar): Use Ranlib_Options when spawning ranlib.
22643 (Initialize): Set the value of ranlib option.
22645 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
22647 * s-parame-linux.adb (Minimum_Stack_Size): Adjust to return 12K
22648 instead of 8K, to reflect the real potential needs for stack-checking
22651 2004-10-26 Pascal Obry <obry@gnat.com>
22653 * s-parame-mingw.adb (Default_Stack_Size): Add some comments.
22655 * s-taprop-mingw.adb (Create_Task): Set initial stack size to 1024. On
22656 Windows only the initial thread stack size can be set so it is good to
22657 start we a low stack size.
22658 The OS will adjust the size as needed.
22660 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
22661 Nicolas Setton <setton@act-europe.fr>
22663 * expect.c, adaint.c, link.c, sysdep.c (unix sections): Guard with
22664 "__unix__" instead of "unix".
22665 The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
22666 sections were just mistakenly ignored. The former is
22667 implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
22668 Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
22669 of hpux. This prevents an unwanted definition of the symbol
22670 convert_addresses in adaint.o.
22672 2004-10-26 Gary Dismukes <dismukes@gnat.com>
22674 * a-exexpr.adb (Setup_Key): Change initial value to 16#DEAD#, for
22675 compatibility with type Unwind_Word on 16-bit targets such as AAMP.
22677 2004-10-26 Cyrille Comar <comar@act-europe.fr>
22679 * a-filico.ads, a-filico.adb: fix incorrect header.
22681 2004-10-26 Javier Miranda <miranda@gnat.com>
22683 * a-ststio.ads: Fix typo in identifier
22685 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
22687 * sem_ch4.adb: Minor reformatting.
22689 2004-10-26 Ed Schonberg <schonberg@gnat.com>
22691 * checks.adb (Expr_Known_Valid): If floating-point validity checks are
22692 enabled, check the result of unary and binary operations when the
22693 expression is the right-hand side of an assignment.
22695 2004-10-26 Vincent Celier <celier@gnat.com>
22697 * clean.adb (Delete): Do not output warnings when in quiet output and
22698 not in verbose mode.
22699 (Force_Deletions): New Boolean flag, defaulted to False
22700 (Delete): Only delete a file if it is writable, and when
22701 Force_Deletions is True.
22702 (Parse_Cmd_Line): New switch -f: set Force_Deletions to True
22703 (Usage): Line for new switch -f
22704 (Clean_Directory): Use GNAT.OS_Lib.Set_Writable instead of rolling our
22707 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
22709 * decl.c (gnat_to_gnu_field): Use the type of the inner object for a
22710 JM type only if its size matches that of the wrapper. When a size is
22711 prescribed and the field is not aliased, remove the wrapper of a JM
22712 type only if the size is not greater than that of the packed array.
22713 (gnat_to_gnu_entity): Change the extension of packed array wrappers
22716 2004-10-26 Geert Bosch <bosch@gnat.com>
22718 * eval_fat.adb (Eps_Model,Eps_Denorm): Remove, no longer used.
22719 (Succ): Re-implement using Scaling, Exponent and Ceiling attributes.
22720 (Pred): Implement in terms of Succ.
22722 2004-10-26 Ed Schonberg <schonberg@gnat.com>
22724 * exp_aggr.adb (Safe_Component): An aggregate component that is an
22725 unchecked conversion is safe for in-place use if the expression of the
22726 conversion is safe.
22727 (Expand_Array_Aggregate): An aggregate that initializes an allocator may
22728 be expandable in place even if the aggregate does not come from source.
22729 (Convert_Array_Aggr_In_Allocator): New procedure to initialize the
22730 designated object of an allocator in place, rather than building it
22731 first on the stack. The previous scheme forces a full copy of the array,
22732 and may be altogether unsusable if the size of the array is too large
22733 for stack allocation.
22735 2004-10-26 Robert Dewar <dewar@gnat.com>
22737 * exp_ch4.adb (Expand_N_Op_Eq): Make sure we expand a loop for array
22738 compares if the component is atomic.
22740 * exp_ch5.adb (Expand_Assign_Array): Make sure we expand a loop for
22741 array assignment if the component type is atomic.
22743 2004-10-26 Ed Schonberg <schonberg@gnat.com>
22744 Eric Botcazou <ebotcazou@act-europe.fr>
22746 * exp_ch6.adb (Expand_Actuals): If the actual for an in-out parameter
22747 is aliased and is a by_reference type, do not pass by copy.
22748 (Expand_N_Function_Call) <Rhs_Of_Assign_Or_Decl>: New function to
22749 detect whether the call is in the right side of an assignment or
22750 the expression of an object declaration. Recurse on component
22751 association within aggregates.
22752 Call it in the condition that determines whether the temporary is
22753 necessary for correct stack-checking.
22755 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
22757 * exp_dist.adb (Build_General_Calling_Stubs): New formal parameter
22758 RACW_Type, used in the PolyORB version.
22759 Rename RCI_Info to RCI_Locator, for consistency between the PolyORB
22760 version and the GARLIC version.
22762 * snames.ads, snames.adb, s-parint.ads, s-parint.adb:
22763 Rename RCI_Info to RCI_Locator for better consistency between the
22764 GARLIC and PolyORB versions of the distributed systems annex.
22765 (DSA_Implementation_Name): This enumeration lists the possible
22766 implementations of the Partition Communication Subsystem for the
22767 Distributed Systems Annex (DSA). The three available implementations
22768 are the dummy stub implementation (No_DSA), and two versions based on
22769 two different distribution runtime libraries: GARLIC and PolyORB. Both
22770 the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution
22772 Change the literal GLADE_DSA to GARLIC_DSA to accurately describe
22775 * rtsfind.ads: Rename RCI_Info to RCI_Locator for better consistency
22776 between the GARLIC and PolyORB versions of the distributed systems
22778 Remove RE_Unbounded_Reclaim_Pool since it is unused.
22780 2004-10-26 Gary Dismukes <dismukes@gnat.com>
22782 * gnat1drv.adb: Suppress calling the back end when
22783 Frontend_Layout_On_Target is true.
22785 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
22787 * g-os_lib.ads, g-os_lib.adb (Set_Executable, Set_Writable,
22788 Set_Read_Only): New subprograms.
22789 These new routines allow the user to set or unset the Owner execute
22790 and Owner write permission flags on a file.
22792 * makegpr.adb, mlib.adb, mlib-prj.adb: Use
22793 GNAT.OS_Lib.Set_Executable instead of rolling our own.
22795 2004-10-26 Matthew Gingell <gingell@gnat.com>
22797 * i-cpp.ads, i-cpp.adb: Change layout of VTable for new C++ ABI.
22799 2004-10-26 Pascal Obry <obry@gnat.com>
22801 * init.c (__gnat_error_handler) [Win32]: Instead of trying to read the
22802 memory before the faulting page we properly test the process read
22803 access for this address using appropriate Win32 routine.
22804 (HPUX sections): guard with "__hpux__" instead of "hpux".
22806 2004-10-26 Robert Dewar <dewar@gnat.com>
22808 * lib-xref.adb (Generate_Reference): Don't complain about reference to
22809 entry parameter if pragma Unreferenced set, since we do not properly
22810 handle the case of multiple parameters.
22812 2004-10-26 Vincent Celier <celier@gnat.com>
22814 * prj-env.adb: (Contains_ALI_Files): New Boolean function
22815 (Ada_Objects_Path.Add): For a library project, add to the object path
22816 the library directory only if there is no object directory or if the
22817 library directory contains ALI files.
22818 (Set_Ada_Paths.Add.Recursive_Add): Ditto
22820 2004-10-26 Vincent Celier <celier@gnat.com>
22822 * prj-nmsc.adb (Language_Independent_Check): Do not forbid virtual
22823 extension of library projects.
22825 * prj-part.adb: If env var ADA_PROJECT_PATH is not defined, project
22826 path defaults to ".:<prefix>/lib/gnat".
22827 (Parse): For an extending all project, allow direct import of a project
22828 that is virtually extended.
22830 * prj-proc.adb (Imported_Or_Extended_Project_From): If a project with
22831 the specified name is directly imported, return its ID. Otherwise, if
22832 an extension of this project is imported, return the ID of the
22835 2004-10-26 Robert Dewar <dewar@gnat.com>
22837 * s-arit64.adb: (Le3): New function, used by Scaled_Divide
22838 (Sub3): New procedure, used by Scaled_Divide
22839 (Scaled_Divide): Substantial rewrite, avoid duplicated code, and also
22840 correct more than one instance of failure to propagate carries
22842 (Double_Divide): Handle overflow case of largest negative number
22843 divided by minus one.
22845 * s-arit64.ads (Double_Divide): Document that overflow can occur in
22846 the case of a quotient value out of range.
22849 2004-10-26 Robert Dewar <dewar@gnat.com>
22851 * s-bitops.adb (Bit_Eq): Remove redundant check.
22853 * s-bitops.ads: Minor comment updates
22854 Change some occurrences of Address to System.Address
22856 * s-carsi8.ads: Fix minor cut-and-paste error in comments
22858 2004-10-26 Ed Schonberg <schonberg@gnat.com>
22860 * sem_attr.adb (Resolve_Attribute, case 'Access): Apply proper
22861 accessibility check to prefix that is a protected operation.
22863 2004-10-26 Ed Schonberg <schonberg@gnat.com>
22865 * sem_ch10.adb (Optional_Subunit): If file of expected subunit is
22866 empty, post message on stub.
22868 2004-10-26 Ed Schonberg <schonberg@gnat.com>
22869 Javier Miranda <miranda@gnat.com>
22871 * sem_ch12.adb (In_Main_Context): Predicate to determine whether the
22872 current instance appears within a unit that is directly in the context
22874 Used to determine whether the body of the instance should be analyzed
22875 immediately after its spec, to make its subprogram bodies available
22876 for front-end inlining.
22877 (Analyze_Formal_Array_Type): Cleanup condition that checks that range
22878 constraint is not allowed on the component type (AARM 12.5.3(3))
22880 2004-10-26 Cyrille Comar <comar@act-europe.fr>
22882 * sem_ch13.adb (Analyze_Attribute_Definition_Clause, case
22883 'Storage_Pool): enhance, document & limit detection of non-sharable
22886 * impunit.adb: Make System.Pool_Global and System.Pool_Local visible.
22888 * s-pooglo.ads: Add more documentation now that this pool is properly
22891 2004-10-26 Ed Schonberg <schonberg@gnat.com>
22893 * sem_ch3.adb (Complete_Private_Subtype): If the full view is a task
22894 or protected type with discriminants, do not constrain the
22895 corresponding record type if the subtype declaration has no
22896 discriminant constraints. This can be the case in source code, or in
22897 the subtype declaration created to rename an actual type within an
22900 2004-10-26 Ed Schonberg <schonberg@gnat.com>
22902 * sem_ch6.adb (Analyze_Subprogram_Body): If body is a subunit for a
22903 different kind of stub (possibly wrong name for file), do not check
22905 (Uses_Secondary_Stack): New subsidiary to Build_Body_To_Inline. If body
22906 includes call to some function that returns an unconstrained type, do
22909 2004-10-26 Ed Schonberg <schonberg@gnat.com>
22911 * sem_elab.adb (Check_Elab_Call): Do not check a call that does not
22912 appear in the code for the main unit. Dependencies among units in the
22913 context of the main unit are established when those other units are
22914 compiled. Otherwise spurious elaboration constraints can generate
22915 incorrect elaboration circularities.
22917 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
22918 Ed Schonberg <schonberg@gnat.com>
22920 * sem_util.adb (Is_Aliased_View): Defend against the case where this
22921 subprogram is called with a parameter that is not an object name. This
22922 situation arises for some cases of illegal code, which is diagnosed
22923 later, and in this case it is wrong to call Is_Aliased, as that might
22924 cause a compiler crash.
22925 (Explain_Limited_Type): Refine previous fix to include
22926 inherited components of derived types, to provide complete information.
22928 * exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
22929 is the prival for a protected object.
22930 It is necessary to mark this entity as a variable, in addition to
22931 flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
22932 modified to avoid checking the Aliased flag on entities that are not
22933 objects. (Checking that flag for non-objects is erroneous and could
22934 lead to a compiler crash).
22936 2004-10-26 Robert Dewar <dewar@gnat.com>
22938 * s-fatgen.adb (Pred): Fix redundant test for X > 0.0, since if
22939 X_Frac = 0.5, then we know that the number X must be positive.
22940 (Succ): Remove the same redundant test, and also fix the primary test
22941 to test for X_Frac = -0.5 (used to be 0.5) which is clearly wrong.
22943 (Decompose): Add fuller comments to spec
22945 2004-10-26 Pascal Obry <obry@gnat.com>
22947 * tracebak.c (IS_BAD_PTR): Use IsBadCodePtr on Win32 to check for ptr
22948 validity (process must have read access). Set to 0 in all other cases.
22949 (STOP_FRAME): Now check for ptr validity to avoid a segmentation
22950 violation on Win32.
22951 (VALID_STACK_FRAME): Check for ptr validity on Win32 to avoid a
22952 segmentation violation.
22954 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
22956 * trans.c (call_to_gnu): For an (in-)out parameter passed by reference
22957 whose type is a constructed subtype of an aliased object with an
22958 unconstrained nominal subtype, convert the actual to the constructed
22959 subtype before taking its address.
22961 2004-10-26 Vincent Celier <celier@gnat.com>
22963 * a-dirval.ads, a-dirval.adb, a-dirval-vms.adb, a-dirval-mingw.adb
22964 (Is_Path_Name_Case_Sensitive): New function
22966 * a-direct.adb (To_Lower_If_Case_Insensitive): New procedure
22967 (Base_Name, Simple_Name, Current_Directory, Compose,
22968 Containing_Directory, Full_Name): Call To_Lower_If_Case_Insensitive on
22971 2004-10-26 Cyrille Comar <comar@act-europe.fr>
22972 Vasiliy Fofanov <fofanov@act-europe.fr>
22973 Vincent Celier <celier@gnat.com>
22975 * gnat_ugn.texi: Generalize "finding memory problems" section into a
22976 "memory management issues" section and document some of the useful
22977 memory pools provided as part of the GNAT library.
22978 Remove "virtual" from declaration of A::method2 in
22979 the simple example of Ada/C++ mixed system.
22980 Library Projects may be virtually extended: their virtual extensions
22981 are not Library Projects.
22982 Added section on extending project hierarchies.
22984 2004-10-19 Aaron W. LaFramboise <aaronavay62@aaronwl.com>
22986 * adaint.c (__gnat_get_libraries_from_registry): Cast value
22988 (__gnat_portable_spawn): Remove const.
22990 * mingw32.h (MAXPATHLEN): Check for previous definition.
22992 2004-10-17 Matthias Klose <doko@debian.org>
22994 * gnatvsn.ads: Set gnat library version to 4.0.
22996 2004-10-05 Vincent Celier <celier@gnat.com>
22998 * mlib-tgt.ads: (Build_Dynamic_Library): New parameter Options_2
23000 2004-10-04 Laurent GUERBY <laurent@guerby.net>
23003 * Makefile.in: Define and use RANLIB_FLAGS.
23005 2004-10-04 Pascal Obry <obry@gnat.com>
23007 * tracebak.c: Always set LOWEST_ADDR to 0 on Win32 (as done on all
23008 other x86 platforms).
23010 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
23012 * s-tassta.adb (Task_Wrapper): Make it Convention C, which makes sense
23013 in general and triggers stack alignment adjustment for thread entry
23014 points on targets where this is necessary.
23016 2004-10-04 Bernard Banner <banner@gnat.com>
23019 * Makefile.in: Add section for powerpc linux
23020 Add variant i-vxwork-x86.ads
23022 * i-vxwork-x86.ads, system-linux-ppc.ads: New files.
23024 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
23026 * init.c (__gnat_initialize): Call an Ada subprogram to perform the
23027 table registration calls when need be. Ensures no reference to the crt
23028 ctors symbol are issued in the SJLJ case, which avoids possible
23029 undefined symbol errors in the case of modules to be statically linked
23032 2004-10-04 Javier Miranda <miranda@gnat.com>
23034 * sem_ch4.adb (Try_Object_Operation): Reformat the code to expand
23035 in-line the code corresponding to subprogram Analyze_Actuals. In
23036 addition, analyze the actuals only in case of subprogram call.
23038 2004-10-04 Ed Falis <falis@gnat.com>
23040 * s-vxwork-x86.ads: (FP_CONTEXT): Defined to be correct size
23042 2004-10-04 Sergey Rybin <rybin@act-europe.fr>
23044 * g-dirope.ads (Base_Name): Clarify the meaning of the Suffix parameter
23045 in the documentation.
23047 2004-10-04 Robert Dewar <dewar@gnat.com>
23049 * sem_ch5.adb (Unblocked_Exit_Count): Now used for blocks as well as
23051 (Analyze_Block_Statement): Add circuitry to detect following dead code
23052 (Check_Unreachable_Code): Handle case of block exit
23054 2004-10-04 Robert Dewar <dewar@gnat.com>
23056 * g-spipat.adb: (XMatch): Avoid warning for Logic_Error call
23057 (XMatchD): Avoid warning for Logic_Error call
23059 2004-10-04 Robert Dewar <dewar@gnat.com>
23061 * exp_ch4.adb (Is_Procedure_Actual): Correct so that this does not
23062 consider expressions buried within a procedure actual to be an actual.
23063 This caused some blowups with uses of packed slices within a procedure
23066 2004-10-04 Robert Dewar <dewar@gnat.com>
23068 * exp_ch3.adb (Needs_Simple_Initialization): Modular packed arrays no
23069 longer need to be initialized to zero.
23070 (Get_Simple_Init_Val): Modular packed arrays no longer need to be
23071 initialized to zero.
23073 * checks.adb (Expr_Known_Valid): Packed arrays are now always
23074 considered valid, even if the representation is modular. That's correct
23075 now that we no longer initialize packed modular arrays to zero.
23077 * exp_dbug.ads: Clarify documentation on handling of PAD and JM
23078 suffixes. These are now documented as the only cases in which the
23079 debugger ignores outer records.
23080 Previously, the spec allowed arbitrary suffixes for this purpose.
23081 Change name of LJM to JM for packed array pad records
23082 Create separate section on packed array handling, and add a whole new
23083 set of comments to this section describing the situation with packed
23084 modular types and justification requirements depending on endianness.
23086 2004-10-04 Robert Dewar <dewar@gnat.com>
23088 * a-except.adb: Add a comment for last change
23090 * einfo.ads: Minor spelling correction in comment
23092 * exp_pakd.adb, gnatdll.adb, prj-attr.ads: Minor reformatting
23094 * sem_ch11.adb: Fix a case of using | instead of \ for continuation
23097 * sem_util.ads: Minor comment update
23099 2004-10-04 Ed Schonberg <schonberg@gnat.com>
23101 * sem_ch6.adb (Analyze_Subprogram_Body): Do not treat Inline as
23102 Inline_Always when in Configurable_Run_Time mode.
23104 * sem_prag.adb (Process_Convention): If entity is an inherited
23105 subprogram, apply convention to parent subprogram if in same scope.
23106 (Analyze_Pragma, case Inline): Do not treat Inline as Inline_Always
23107 when in Configurable_Run_Time mode.
23109 2004-10-04 Ed Schonberg <schonberg@gnat.com>
23111 * sem_ch3.adb (Build_Derived_Record_Type): Set First/Last entity of
23112 class_wide type after component list has been inherited.
23114 2004-10-04 Ed Schonberg <schonberg@gnat.com>
23116 * sem_ch12.adb (Check_Generic_Actuals): New predicate
23117 Denotes_Previous_Actual, to handle properly the case of a private
23118 actual that is also the component type of a subsequent array actual.
23119 The visibility status of the first actual is not affected when the
23120 second is installed.
23121 (Process_Nested_Formal): Subsidiary of Instantiate_Formal_Package, to
23122 make fully recursive the treatment of formals of packages declared
23124 (Restore_Nested_Formal): Subsidiary of Restore_Private_Views, to undo
23125 the above on exit from an instantiation.
23126 (Denotes_Formal_Package): When called from Restore_Private_Views, ignore
23127 current instantiation which is now complete.
23128 (Analyze_Package_Instantiation): No instantiated body is needed if the
23129 main unit is generic. Efficient, and avoid anomalies when a instance
23130 appears in a package accessed through rtsfind.
23132 2004-10-04 Ed Schonberg <schonberg@gnat.com>
23134 * exp_ch6.adb (Expand_N_Function_Call): If stack checking is enabled,
23135 do not generate a declaration for a temporary if the call is part of a
23136 library-level instantiation.
23138 2004-10-04 Ed Schonberg <schonberg@gnat.com>
23140 * sem_util.adb (Explain_Limited_Type): Ignore internal components when
23141 searching for a limited component to flag.
23143 * exp_attr.adb (Freeze_Stream_Subprogram): Subsidiary procedure to
23144 expansion of Input, to account for the fact that the implicit call
23145 generated by the attribute reference must freeze the user-defined
23146 stream subprogram. This is only relevant to 'Input, because it can
23147 appear in an object declaration, prior to the body of the subprogram.
23149 * sem_ch13.adb (Rep_Item_Too_Late): Make the error non-serious, so that
23150 expansion can proceed and further errors uncovered.
23151 (Minor clean up): Fix cases of using | instead of \ for continuation
23154 2004-10-04 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
23156 * cuintp.c, decl.c, utils2.c: Use gcc_assert and gcc_unreachable.
23158 * trans.c (assoc_to_constructor): Fix unused var warning if no checking.
23159 (gnat_gimplify_expr, case ADDR_EXPR): Fix error in last change.
23160 Use gcc_assert and gcc_unreachable.
23162 * decl.c (gnat_to_gnu_entity, case object): Check and process a
23163 specified alignment before validating size.
23164 (gnat_to_gnu_entity) <E_Modular_Integer_Subtype>: Create a
23165 stripped-down declaration for the type of the inner field when making
23168 * utils.c (finish_record_type): Do not compute the size in units
23169 incrementally. Instead compute it once for the rep clause case.
23170 Use gcc_assert and gcc_unreachable.
23172 2004-10-04 Vincent Celier <celier@gnat.com>
23174 * a-dirval-mingw.adb (Invalid_Character): Add '\' as invalid character
23176 (Is_Valid_Path_Name): Take '/' as a directory separator.
23178 2004-10-04 Vincent Celier <celier@gnat.com>
23180 * prj-part.adb (Parse_Single_Project): Call Is_Extending_All
23181 (Extended_Project) only if Extended_Project is defined, to avoid
23183 (Post_Parse_Context_Clause): Always call Set_Path_Name_Of with a
23185 (Parse_Single_Project): Ditto.
23187 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not call
23188 Add_To_Project_Path for virtual projects.
23190 2004-10-04 Vincent Celier <celier@gnat.com>
23192 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
23193 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
23194 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb, mlib-tgt-mingw.adb,
23195 mlib-tgt-vxworks.adb, mlib-tgt.adb (Build_Dynamic_Library): New
23196 parameter Options_2.
23198 * mlib-prj.ads, mlib-prj.adb (Build_Library): Call
23199 Build_Dynamic_Library with an empty Options_2.
23201 * mlib-utl.ads, mlib-utl.adb (Gcc): Parameter Options_2 has no
23204 * makegpr.adb (Get_Imported_Directories.add): Remove trailing
23205 directory separator, if any.
23206 (Gprmake): Do not allow mains on the command line for library projects.
23207 Do not attempt to link when the project is a library project.
23208 (Library_Opts): New table to store Library_Options.
23209 (Build_Library): If Library_Options is specified, pass these options
23210 when building a shared library.
23212 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
23214 * s-tposen.adb (Service_Entry): The object must be always unlocked at
23215 the end of this procedure now that the unlock operation was inserted
23218 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
23220 * targparm.ads, targparm.adb (Targparm_Tags): Add PAS value
23221 corresponding to the Preallocated_Stacks flags in System.
23222 (Get_Target_Parameters): Including the processing for
23223 Preallocated_Stacks.
23225 * system.ads, system-vxworks-x86.ads, system-darwin-ppc.ads,
23226 system-vms_64.ads, system-unixware.ads, system-linux-ia64.ads,
23227 system-freebsd-x86.ads, system-lynxos-ppc.ads, system-lynxos-x86.ads,
23228 system-linux-x86_64.ads, system-tru64.ads, system-aix.ads,
23229 system-vxworks-sparcv9.ads, system-vxworks-xscale.ads,
23230 system-solaris-x86.ads, system-irix-o32.ads, system-irix-n32.ads,
23231 system-hpux.ads, system-vxworks-m68k.ads, system-linux-x86.ads,
23232 system-vxworks-mips.ads, system-os2.ads, system-interix.ads,
23233 system-solaris-sparc.ads, system-solaris-sparcv9.ads, system-vms.ads,
23234 system-mingw.ads, system-vms-zcx.ads, system-vxworks-ppc.ads,
23235 system-vxworks-alpha.ads: Add the flag Preallocated_Stacks, that is
23236 used to signal whether the compiler creates the required stacks and
23237 descriptors for the different tasks (when True) or it is done by the
23238 underlying operating system at run time (when False).
23239 It is initially set to False in all targets.
23241 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Create the task stack
23242 if it is supported by the target.
23243 (Make_Task_Create_Call): Pass the stack address if it has been
23244 previously created. Otherwise pass a Null_Address.
23246 * snames.adb: Add _stack.
23248 * snames.ads: Add Name_uStack. Required to allow the expander to
23249 statically allocated task stacks.
23251 * s-tarest.ads, s-tarest.adb (Create_Restricted_Task): Add
23252 Stack_Address argument.
23253 Check that its value is equal to Null_Address because this target does
23254 not support the static stack allocation.
23256 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
23258 * usage.adb: Change "pragma inline" to "pragma Inline" in information
23261 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
23263 * exp_dist.adb: Split declaration of asynchronous flag out of
23264 Add_RACW_Read_Attribute.
23265 Minor reformatting for better alignment with PolyORB version.
23266 Store the entity for the asynchronous flag of an RACW, rather than the
23267 expression, in the asynchronous flags table. This will allow this flag
23268 to be used in other subprograms beside Add_RACW_Read_Attribute.
23270 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
23272 * g-socket.ads, g-socket.adb, g-socthi.adb, socket.c,
23273 g-soccon-aix.ads, g-soccon-irix.ads, g-soccon-hpux.ads,
23274 g-soccon-interix.ads, g-soccon-solaris.ads, g-soccon-vms.adb,
23275 g-soccon-mingw.ads, g-soccon-vxworks.ads, g-soccon-freebsd.ads,
23276 g-soccon.ads, g-soccon-unixware.ads, g-soccon-tru64.ads: Add new
23277 sockets constant MSG_NOSIGNAL (Linux-specific).
23278 Add new sockets constant MSG_Forced_Flags, list of flags to be set on
23279 all Send operations.
23280 For Linux, set MSG_NOSIGNAL on all send operations to prevent them
23281 from trigerring SIGPIPE.
23282 Rename components to avoid clash with Ada 2005 possible reserved
23284 (Check_Selector): When the select system call returns with an error
23285 condition, propagate Socket_Error to the caller.
23287 2004-10-01 Jan Hubicka <jh@suse.cz>
23289 * misc.c (gnat_expand_body): Update call of tree_rest_of_compilation.
23291 2004-09-23 Robert Dewar <dewar@gnat.com>
23294 * sem_prag.adb (Process_Import_Or_Interface): Don't set Is_Public here,
23295 instead do this at freeze time (we won't do it if there is an address
23297 Change "pragma inline" to "pragma Inline" in information and error
23299 Minor reformatting.
23301 * freeze.adb (Check_Address_Clause): Remove previous change, not the
23302 right way of doing things after all.
23303 (Freeze_Entity): For object, set Is_Public for imported entities
23304 unless there is an address clause present.
23306 2004-09-21 Olivier Hainque <hainque@act-europe.fr>
23308 * decl.c (gnat_to_gnu_entity) <E_General_Access_Type>: Check for a
23309 dummy designated type via TYPE_MODE instead of COMPLETE_TYPE_P. This
23310 ensures proper handling of types with rep clauses, which might have
23311 their TYPE_SIZE set already.
23313 2004-09-21 Robert Dewar <dewar@gnat.com>
23315 * decl.c (gnat_to_gnu_type, case E_Modular_Integer_Type): Wrap modular
23316 packed array types in both little- and big-endian cases. This change
23317 ensures that we no longer count on the unused bits being initialized
23318 for such types (and in particular ensures that equality testing will
23319 only read the relevant bits).
23320 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
23321 These changes mean that we no longer need to initialize small packed
23323 (gnat_to_gnu_entity) <E_Record_Subtype>: Apply the same
23324 optimization to an LJM field as to its parent field.
23326 * ada-tree.h, trans.c, utils.c, utils2.c:
23327 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P

23451 raise Program_Error if called from a protected operation.
23453 * s-taprob.adb (Lock): When pragma Detect_Blocking is active increase
23454 the protected action nesting level.
23455 (Lock_Read_Only): When pragma Detect_Blocking is active increase the
23456 protected action nesting level.
23457 (Unlock): When pragma Detect_Blocking is active decrease the protected
23458 action nesting level.
23460 * s-taskin.adb (Initialize_ATCB): Initialize to 0 the
23461 Protected_Action_Nesting.
23463 * s-taskin.ads: Adding the field Protected_Action_Nesting to the
23464 Common_ATCB record. It contains the dynamic level of protected action
23465 nesting for each task. It is needed for checking whether potentially
23466 blocking operations are called from protected operations.
23467 (Detect_Blocking): Adding a Boolean constant reflecting whether pragma
23468 Detect_Blocking is active or not in the partition.
23470 * s-tasren.adb (Call_Simple): When pragma Detect_Blocking is active,

23504 contains the required machinery for handling that.
23506 * sem_util.ads: Change comment associated to procedure
23507 Check_Potentially_Blocking_Operation.
23508 This procedure does not insert a call for raising the exception because
23509 that is currently done by the run time.
23511 * raise.h (__gnat_set_globals): Pass the detect_blocking parameter.
23513 * init.c: Add the global variable __gl_detect_blocking that indicates
23514 whether pragma Detect_Blocking is active (1) or not (0). Needed for
23515 making the pragma available at run time.
23516 (__gnat_set_globals): Pass and update the detect_blocking parameter.

23523 * ali.adb (Scan_ALI): Set the Detect_Blocking value to true if the flag
23524 DB is found in the ali file. Any unit compiled with pragma
23525 Detect_Blocking active forces its effect in the whole partition.
23527 * a-retide.adb (Delay_Until): Raise Program_Error if pragma
23528 Detect_Blocking is active and delay is called from a protected
23531 * bindgen.adb (Gen_Adainit_Ada): When generating the call to

23545 (Register_Receiving_Stub): Add Subp_Info formal parameter.
23546 Update API in placeholder implemetation of s-parint to reflect changes
23547 in distribution runtime library.
23549 * sem_ch3.adb (Expand_Derived_Record): Rename to
23550 Expand_Record_Extension.
23552 * sem_disp.adb (Check_Controlling_Formals): Improve error message for
23553 primitive operations of potentially distributed object types that have
23554 non-controlling anonymous access formals.
23556 * sem_dist.ads, sem_dist.adb (Build_RAS_Primitive_Specification): New
23558 New implementation of expansion for remote access-to-subprogram types,
23559 based on the RACW infrastructure.
23560 This version of sem_dist is compatible with PolyORB/DSA as well as
23563 * sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
23564 Asynchrronous that applies to a remote access-to-subprogram type, mark
23565 the underlying RACW type as asynchronous.
23567 * link.c: FreeBSD uses GNU ld: set __gnat_objlist_file_supported and
23568 __gnat_using_gnu_linker to 1.
23570 * Makefile.rtl, impunit.adb, g-perhas.ads, g-pehage.ads,
23571 g-pehage.adb: Rename GNAT.Perfect_Hash.Generators to

23577 * exp_ch3.adb (Expand_Derived_Record): Rename to
23578 Expand_Record_Extension.
23579 (Build_Record_Init_Proc.Build_Assignment): The default expression in
23580 a component declaration must remain attached at that point in the
23581 tree so New_Copy_Tree copies it if the enclosing record type is derived.
23582 It is therefore necessary to take a copy of the expression when building
23583 the corresponding assignment statement in the init proc.
23584 As a side effect, in the case of a derived record type, we now see the
23585 original expression, without any rewriting that could have occurred
23586 during expansion of the ancestor type's init proc, and we do not need
23587 to go back to Original_Node.
23589 * exp_ch3.ads (Expand_Derived_Record): Rename to
23590 Expand_Record_Extension.
23592 * exp_dist.ads, exp_dist.adb (Underlying_RACW_Type): New subprogram.

23597 subprogram. The proxy object is used as the designated object
23598 for RAS values on the same partition (unless All_Calls_Remote applies).
23599 (Build_Get_Unique_RP_Call): New subprogram. Build a call to
23600 System.Partition_Interface.Get_Unique_Remote_Pointer.

23605 New implementation of expansion for remote access-to-subprogram types,
23606 based on the RACW infrastructure.
23608 * exp_dist.ads (Copy_Specification): Update comment to note that this
23609 function can copy the specification from either a subprogram
23610 specification or an access-to-subprogram type definition.
23612 2004-09-09 Ed Schonberg <schonberg@gnat.com>
23614 * sem_type.adb (Disambiguate): Handle properly an accidental ambiguity
23615 in an instance, between an explicit subprogram an one inherited from a
23616 type derived from an actual.
23618 * exp_ch6.adb (Expand_N_Subprogram_Body): If polling is enabled, do not
23619 add a polling call if the subprogram is to be inlined by the back-end,
23620 to avoid repeated calls with multiple inlinings.
23622 * checks.adb (Apply_Alignment_Check): If the expression in the address
23623 clause is a call whose name is not a static entity (e.g. a dispatching
23624 call), treat as dynamic.

23628 * g-trasym.ads: Minor reformatting
23630 * exp_ch3.adb (Component_Needs_Simple_Initialization): Don't except

23639 2004-09-09 Pascal Obry <obry@gnat.com>
23641 * mdll.ads, mdll.adb (Build_Dynamic_Library): New parameter Map_File to
23642 enable map file generation. Add the right option to generate the map
23643 file if Map_File is set to True.
23645 * gnatdll.adb (Gen_Map_File): New variable.
23646 (Syntax): Add info about new -m (Map_File) option.

23674 * sem_util.adb (Requires_Transient_Scope): Re-enable handling
23675 of variable length temporaries for function return now that the
23676 back-end and gigi support it.

23753 consistent treatment of entity references contained within the
23754 enclosed procedure call.
23756 2004-09-01 Vincent Celier <celier@gnat.com>
23758 * bindgen.adb: (Set_EA_Last): New procedure

23870 for a global aliased object with a variable size and an unconstrained
23871 nominal subtype, pretend there is no initializer if the one we have is
23872 incomplete, and avoid referencing an inexistant component in there. The

23897 unit, this is an attempt to inline a construct that is not available in
23898 the current restricted mode, so abort rather than trying to continue.
23900 * sem_ch3.adb (Build_Underlying_Full_View): If the new type has
23901 discriminants that rename those of the parent, recover names of

23933 returning C.int, to avoid using a derived boolean type.
23935 * exp_ch5.adb (Make_Tag_Ctrl_Assignments): Use

25860 hand side. Warnings are now properly emitted when variables or prefixes
25861 are assigned but not read.

25864 left hand side referenced variables. Private access types do not
25865 produce the warning "variable ... is assigned but never read".
25866 Add also additional checks to left hand side referenced variables.

25888 interpretations for rewritten right operand.
25889 (Set_Mixed_Mode_Operand): Handle properly a universal real operand when

26278 * prj-proc.adb (Recursive_Process): Inherit attribute Languages from
26279 project being extended, if Languages is not declared in extending
26282 2004-05-17 Javier Miranda <miranda@gnat.com>
26284 * sem_ch10.adb (Install_Limited_Withed_Unit): Do not install the
26285 limited view of a visible sibling.
26287 2004-05-14 Robert Dewar <dewar@gnat.com>
26289 * gnat_ugn.texi: Minor change to -gnatS documentation
26291 * sprint.adb: Remove some instances of Assert (False) and for this
26292 purpose replace them by output of a ??? string.
26294 * checks.adb, exp_aggr.adb, sem_elim.adb: Remove useless pragma
26297 * lib-writ.adb, lib-load.adb, lib.ads, lib.adb: Remove Dependent_Unit
26298 flag processing. This was suppressing required dependencies in
26299 No_Run_Time mode and is not needed since the binder does not generate
26300 references for things in libgnat anyway.
26302 * sem_ch3.adb (Access_Type_Declaration): Reorganize code to avoid GCC
26305 2004-05-14 Thomas Quinot <quinot@act-europe.fr>
26307 * gnat_ugn.texi: Document AIX-specific issue with initialization of
26310 * exp_ch4.adb (Insert_Dereference_Action): Do not generate dereference
26311 action for the case of an actual parameter in an init proc call.
26313 2004-05-14 Ed Schonberg <schonberg@gnat.com>
26315 * sem_ch4.adb (Analyze_Selected_Component): If prefix is a protected
26316 subtype, check visible entities in base type.
26318 * exp_ch7.adb (Clean_Simple_Protected_Objects): Do not generate cleanup
26319 actions if the object is a renaming.
26321 * sem_ch12.adb (Same_Instantiated_Entity): Predicate for
26322 Check_Formal_Package_Instance, to determine more precisely when the
26323 formal and the actual denote the same entity.
26325 2004-05-14 Javier Miranda <miranda@gnat.com>
26327 * par-ch10.adb (P_Context_Clause): Complete documentation on AI-262
26329 * sem_ch10.adb (Analyze_With_Clause): After analyzed, the entity
26330 corresponding to a private_with must be removed from visibility; it
26331 will be made visible later, just before we analyze the private part of
26333 (Check_Private_Child_Unit): Allow private_with clauses in public
26335 (Install_Siblings): Make visible the private entities of private-withed
26337 (Install_Withed_Unit): Do not install the private withed unit if we
26338 are compiling a package declaration and the Private_With_OK flag was
26339 not set by the caller. These declarations will be installed later,
26340 just before we analyze the private part of the package.
26342 * sem_ch3.adb (Analyze_Object_Declaration): In case of errors detected
26343 during the evaluation of the expression that initializes the object,
26344 decorate it with the expected type to avoid cascade errors.
26347 * sem_ch6.adb (Analyze_Subprogram_Body): If we are compiling a library
26348 subprogram we have to install the private_with clauses after its
26349 specification has been analyzed (as documented in AI-262.TXT).
26351 * sem_ch8.adb (Has_Private_With): New function. Determines if the
26352 current compilation unit has a private with on a given entity.
26353 (Find_Direct_Name): Detect the Beaujolais problem described in
26356 * sem_utils.ads, sem_util.adb (Is_Ancestor_Package): New function. It
26357 provides the functionality of the function Is_Ancestor that was
26358 previously available in sem_ch10. It has been renamed to avoid
26361 * sprint.adb (Sprint_Node_Actual): Print limited_with clauses
26363 2004-05-14 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
26365 * utils.c (build_vms_descriptor): Use SImode pointers.
26367 2004-05-14 Vasiliy Fofanov <fofanov@act-europe.fr>
26369 * gnat_ugn.texi: Revised chapter "GNAT and Libraries".
26371 2004-05-14 GNAT Script <nobody@gnat.com>
26373 * Make-lang.in: Makefile automatically updated
26375 2004-05-14 Arnaud Charlet <charlet@act-europe.fr>
26377 Renaming of target specific files for clarity
26379 * Makefile.in: Rename GNAT target specific files.

26521 * trans.c (gnat_stabilize_reference_1): Remove case 'b'.
26523 2004-05-13 Diego Novillo <dnovillo@redhat.com>
26525 Merge from tree-ssa-20020619-branch.
26527 * config-lang.in (boot_language, build_by_default): Set
26529 * utils.c (unchecked_convert): Use OEP_ONLY_CONST.
26530 (max_size): Add static chain op for call_expr.
26532 2004-05-12 Richard Sandiford <rsandifo@redhat.com>
26535 * 5gmastop.adb (Roff): Choose between '4' and '0', not '4' and ' '.
26537 2004-05-11 Roger Sayle <roger@eyesopen.com>
26539 * utils.c (max_size): Use MIN_EXPR to find the minimum value of a
26542 2004-05-10 Doug Rupp <rupp@gnat.com>
26544 * 5qsystem.ads: Remove Short_Address subtype declaration. Moved to
26547 * s-auxdec.ads: Add Short_Address subtype (moved here from System).
26549 * Makefile.in: [VMS]: Add translation for 5qauxdec.ads.
26551 * init.c: [VMS] Macroize LIB$ calls for IA64 and Alpha.
26552 Fixes undefined symbols in IA64 gnatlib.
26554 * 5vinmaop.adb: Reference s-auxdec for Short_Address.
26556 * 5xsystem.ads, 5vsystem.ads: Back out last change (addition of subtype
26557 Short_Address). This will be moved to system.auxdec.
26559 2004-05-10 Thomas Quinot <quinot@act-europe.fr>
26561 * sem_util.adb: Replace test for presence of a node that is always
26562 present with a call to Discard_Node.
26564 * sem_ch10.adb (Analyze_Compilation_Unit): Remove superfluous call to
26565 Analyze on the library unit node after generation of distribution stub
26566 constructs. The call was a no-op because Unit_Node has already been
26567 Analyzed, and the tree fragments for the distribution stubs are
26568 analyzed as they are inserted in Exp_Dist.
26569 Update comment regarding to distribution stubs to reflect that we
26570 do not generate stub in separate files anymore.
26572 * einfo.ads: Clarify the fact that a tagged private type has the
26573 E_Record_Type_With_Private Ekind.
26575 * erroutc.adb: Minor reformatting
26577 * erroutc.ads (Max_Msg_Length): Increase to cover possible larger
26578 values if line length is increased using -gnatyM (noticed during code

26584 2004-05-10 Ed Schonberg <schonberg@gnat.com>
26587 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): If prefix
26588 has been rewritten as an explicit dereference, retrieve type of
26589 original node to check for possibly unconstrained record type.
26591 2004-05-10 Ed Schonberg <schonberg@gnat.com>
26593 * exp_ch7.adb (Check_Visibly_Controlled): If given operation is not
26594 overriding, use the operation of the parent unconditionally.
26596 * sem_ch4.adb (Remove_Address_Interpretations): Remove address
26597 operation when either operand is a literal, to avoid further
26600 * sem_ch6.adb (New_Overloaded_Entity): If new entity is inherited and
26601 overridden by a previous explicit declaration, mark the previous entity
26604 * sem_disp.adb (Check_Dispatching_Operation): New predicate
26605 Is_Visibly_Controlled, to determine whether a declaration of a
26606 primitive control operation for a derived type overrides an inherited
26607 one. Add warning if the explicit declaration does not override.
26609 2004-05-10 Vincent Celier <celier@gnat.com>
26611 * gnatls.adb (Gnatls): Initialize Snames, to avoid assertion error in
26612 some cases when the sources are no longer present.
26614 * make.adb (Collect_Arguments): Fail if an external source, not part
26615 of any project need to be compiled, when switch -x has not been
26618 * makeusg.adb: Document new switch -x
26620 * opt.ads (External_Unit_Compilation_Allowed): New Boolean flag,
26621 defaulted to False.
26623 * switch-m.adb (Scan_Make_Switches): New switch -x
26625 * vms_data.ads: Add VMS qualifier /NON_PROJECT_UNIT_COMPILATION for
26626 gnatmake switch -x.
26628 * gnat_ugn.texi: Document new gnatmake switch -x
26630 2004-05-10 Eric Botcazou <ebotcazou@act-europe.fr>
26632 * misc.c (gnat_init_options): Set flag_zero_initialized_in_bss to 0.
26634 * utils.c (create_var_decl): Do not modify the DECL_COMMON flag.

27738 * sem_prag.adb (Set_Exported): Warn about making static as result of
27739 export only when the export is coming from source. This may be not
27740 be true e.g. on VMS where we expand export pragmas for exception codes
27741 together with imported or exported exceptions, and we don't want the
27742 user to be warned about something he didn't write.
27744 2004-04-08 Thomas Quinot <quinot@act-europe.fr>
27746 * sem_util.adb (Note_Possible_Modification): Reorganize to remove code
27747 duplication between normal entities and those declared as renamings.

27847 specified radix_digits is greater or equal to machine_mantissa.
27849 2004-04-05 Javier Miranda <miranda@gnat.com>
27851 * par-ch3.adb: Complete documentation of previous change
27852 Correct wrong syntax documentation of the OBJECT_DECLARATION rule

27865 as is done for non-private derived record types.
27867 * sem_ch4.adb (Remove_Abstract_Operations): New subprogram to implement
27868 Ada 2005 AI-310: an abstract non-dispatching operation is not a

27877 * exp_ch6.adb (Rewrite_Function_Call): When rewriting an assignment
27878 statement whose right-hand side is an inlined call, save a copy of the
27879 original assignment subtree to preserve enough consistency for
27880 Analyze_Assignment to proceed.
27882 * sem_ch5.adb (Analyze_Assignment): Remove a costly copy of the
27883 complete assignment subtree which is now unnecessary, as the expansion
27884 of inlined call has been improved to preserve a consistent assignment
27885 tree. Note_Possible_Modification must be called only
27886 after checks have been applied, or else unnecessary checks will
27889 * sem_util.adb (Note_Possible_Modification): Reorganise the handling
27890 of explicit dereferences that do not Come_From_Source:
27891 - be selective on cases where we must go back to the dereferenced
27892 pointer (an assignment to an implicit dereference must not be
27893 recorded as modifying the pointer);
27894 - do not rely on Original_Node being present (Analyze_Assignment
27895 calls Note_Possible_Modification on a copied tree).
27897 * sem_warn.adb (Check_References): When an unset reference to a pointer
27898 that is never assigned is encountered, prefer '<pointer> may be null'

27968 a string literal, create a temporary for it, constant folding only
27969 handles scalars here.
27971 2004-04-01 Vincent Celier <celier@gnat.com>

28152 allows to configure paths for an executable name (gnatmake) different
28153 from the current one (gnatdist).
28155 2004-03-29 Ed Schonberg <schonberg@gnat.com>
28157 * exp_ch6.adb (Expand_Call): A call to a function declared in the
28158 current unit cannot be inlined if it appears in the body of a withed
28159 unit, to avoid order of elaboration problems in gigi.
28161 * exp_ch9.adb (Build_Protected_Sub_Specification): Generate debugging
28162 information for protected (wrapper) operation as well, to simplify gdb
28165 * sem_ch6.adb (Analyze_Subprogram_Body): For a private operation in a
28166 protected body, indicate that the entity for the generated spec comes
28167 from source, to ensure that references are properly generated for it.

28208 a classwide type (for which Is_Object_Reference holds), but it can
28209 also be a value conversion for an access-to-classwide type. In the
28210 latter case, there is an implicit dereference, and the original node
28211 for the prefix does not verify Is_Object_Reference.
28213 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): A view

28238 * sem_elab.adb (Check_Elab_Call): Refine loop that checks for default
28239 value expressions to ensure that calls within a component definition
28240 will be checked (since those are evaluated during the record type's

28291 * sem_ch10.adb (Analyze_Compilation_Unit): When generating a
28292 declaration for a child subprogram body that acts as a spec, indicate
28293 that the entity in the declaration needs debugging information.
28295 * sem_ch3.adb (Complete_Private_Subtype): Do not build an underlying
28296 full view if the subtype is created for a constrained record component;
28297 gigi has enough information to construct the record, and there is no
28298 place in the tree for the declaration.
28300 * sem_ch6.adb (Build_Body_To_Inline): Use an internal name without
28301 serial number for the dummy body that is built for analysis, to avoid
28302 inconsistencies in the generation of internal names when compiling
28305 2004-03-22 Thomas Quinot <quinot@act-europe.fr>
28307 * sem_util.adb (Is_Object_Reference): A view conversion denotes an
28310 2004-03-22 GNAT Script <nobody@gnat.com>

28341 2004-03-19 Olivier Hainque <hainque@act-europe.fr>
28343 * decl.c (gnat_to_gnu_entity, case E_Exception): Handle VMS exceptions
28344 as regular exception objects and not as mere integers representing the
28345 condition code. The latter approach required some dynamics to mask off
28346 severity bits, which did not fit well into the GCC table based model.
28347 (gnat_to_gnu_entity, objects): Don't supply an external name for VMS
28348 exception data objects. We don't it and it would conflict with the other
28349 external symbol we have to generate for such exceptions.
28351 * trans.c (tree_transform, case N_Exception_Handler): Remove part of
28352 the special code for VMS exceptions, since these are now represented
28353 as regular exceptions objects.
28355 2004-03-19 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
28357 * decl.c (debug_no_type_hash): Remove.

28361 2004-03-19 Laurent Guerby <laurent@guerby.net>
28363 * sem_prag.adb (Suppress_Unsuppress_Echeck): use loop instead of
28364 aggregate, allows bootstrap from 3.3 on powerpc-darwin.
28366 2004-03-18 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
28368 * ada-tree.h (TYPE_LEFT_JUSTIFIED_MODULAR_P): Add checking.

28386 2004-03-18 Thomas Quinot <quinot@act-europe.fr>
28388 * adaint.c: Update comments.
28390 * Makefile.in: set PREFIX_OBJS, SYMLIB, THREADSLIB, and
28391 GNATLIB_SHARED for FreeBSD.
28393 2004-03-18 Jose Ruiz <ruiz@act-europe.fr>
28395 * init.c [VxWorks]: Do not fix the stack size for the environment task.
28396 When needed (stack checking) the stack size is retrieved
28397 from the VxWorks kernel.
28399 * Makefile.in: Flag -nostdinc is required when building the run time
28400 for avoiding looking for files in the base compiler.
28401 Add the VxWorks specific version of the package body for
28402 System.Stack_checking.Operations (5zstchop.adb).
28404 * Make-lang.in: Add the object file for
28405 System.Stack_Checking.Operations.

28412 * s-stache.ads, s-stache.adb: Move the operations related to stack
28413 checking from this package to package System.Stack_Checking.Operations.
28414 This way, stack checking operations are only linked in the final
28415 executable when using the -fstack-check flag.
28417 2004-03-18 Doug Rupp <rupp@gnat.com>
28419 * Makefile.in [VMS]: Handle 64 bit specs (5qsystem.ads, 5xcrtl.ads).

28429 (Add_To_Source_Path, Add_To_Object_Path): New procedures, to replace
28430 the procedures Add_To_Path_File.
28431 (Set_Ada_Paths): Accumulate source and object dirs in the tables,
28432 making sure that each directory is present only once and, for object
28433 dirs, when a directory already present is added, the duplicate is
28434 removed and the directory is always put as the last in the table.
28435 Write the path files at the end of these accumulations.
28437 * prj-nmsc.adb (Record_Source): Add source file name in hash table
28438 Files_Htable for all sources.
28440 * prj-proc.adb (Process): Remove restrictions between not directly
28441 related extending projects.

28449 parameter Trusted_Mode.
28451 2004-03-18 Sergey Rybin <rybin@act-europe.fr>
28453 * scn.adb (Determine_License): Take into account a degenerated case
28454 when the source contains only comments.
28456 2004-03-18 Ed Schonberg <schonberg@gnat.com>
28458 * sem_warn.adb (Check_References): For a warning on a selected
28459 component that does not come from source, locate an uninitialized
28460 component of the record type to produce a more precise error message.
28462 2004-03-15 Jerome Guitton <guitton@act-europe.fr>
28464 * 3zsoccon.ads: Fix multicast options.
28466 * s-thread.ads: Move unchecked conversion from ATSD_Access to Address
28469 2004-03-15 Robert Dewar <dewar@gnat.com>
28471 * sem_prag.adb: Make sure No_Strict_Aliasing flag is set right when
28472 pragma used for a private type.
28474 * lib-xref.adb (Generate_Reference): Do not generate warning if
28475 reference is in a different unit from the pragma Unreferenced.
28477 * 5vtpopde.adb: Minor reformatting
28478 Fix casing of To_Task_ID
28480 * sem_ch13.adb (Validate_Unchecked_Conversion): Set No_Strict_Aliasing
28481 flag if we have an unchecked conversion to an access type in the same
28484 2004-03-15 Geert Bosch <bosch@gnat.com>
28486 * a-ngcoty.adb (Modulus): In alternate formula for large real or
28487 imaginary parts, use Double precision throughout.
28489 * a-tifiio.adb (Put_Scaled): Remove remaining pragma Debug. Not only
28490 we want to be able to compile run-time with -gnata for testing, but
28491 this may also be instantiated in user code that is compiled with -gnata.
28493 2004-03-15 Olivier Hainque <hainque@act-europe.fr>
28495 * s-stalib.ads (Exception_Code): New type, to represent Import/Export
28496 codes. Having a separate type for this is useful to enforce consistency
28497 throughout the various run-time units.
28498 (Exception_Data): Use Exception_Code for Import_Code.
28500 * s-vmextra.ads, s-vmexta.adb: Use Exception_Code instead of a mix of
28501 Natural and Integer in various places.

28503 with the severity bits masked off.
28504 (Register_VMS_Exception): Handle the additional exception data pointer

28508 component, now reflected by an exported accessor.
28509 (is_handled_by): New routine to compute whether the propagated
28510 occurrence matches some handler choice specification. Extracted out of
28511 get_action_description_for, and expanded to take care of the VMS
28513 (get_action_description_for): Use is_handled_by instead of an explicit
28514 complex condition to decide if the current choice at hand catches the
28515 propagated occurrence.
28517 * raise.h (Exception_Code): New type for C.
28519 * rtsfind.ads (RE_Id, RE_Unit_Table): Add
28520 System.Standard_Library.Exception_Code, to allow references from the
28521 pragma import/export expander.
28523 * a-exexpr.adb (Is_Handled_By_Others, Language_For, Import_Code_For):
28524 New accessors to allow easy access to GNAT exception data
28526 (GNAT_GCC_Exception record, Propagate_Exception): Get rid of the
28527 redundant Handled_By_Others component, helper for the personality
28528 routine which will now be able to call the appropriate exception data
28531 * cstand.adb (Create_Standard): Adjust the type of the Import_Code
28532 component of Standard_Exception_Type to be the closest possible to
28533 Exception_Code in System.Standard_Library, that we cannot get at this
28534 point. Expand a ??? comment to notify that this type node should
28535 probably be rewritten later on.
28537 * exp_prag.adb (Expand_Pragma_Import_Export_Exception): Adjust the
28538 registration call to include a pointer to the exception object in the
28541 * init.c (__gnat_error_handler): Use Exception_Code and Base_Code_In
28542 instead of int and explicit bitmasks.
28544 2004-03-15 Vincent Celier <celier@gnat.com>
28546 * vms_data.ads: Add new GNAT BIND qualifier /STATIC. Makes /NOSHARED
28547 equivalent to /STATIC and /NOSTATIC equivalent to /SHARED.
28549 * a-tasatt.adb (To_Access_Code): Remove this UC instantiation, no
28550 longer needed now that it is in the spec of
28551 System.Tasking.Task_Attributes.
28553 * adaint.h, adaint.c: (__gnat_create_output_file): New function
28555 * gnatcmd.adb: Fix bug introduced in previous rev: /= instead of =
28557 * g-os_lib.ads, g-os_lib.adb (Create_Output_Text_File): New function.
28559 * make.adb (Gnatmake): Do not check the executable suffix; it is being
28560 taken care of in Scan_Make_Arg.
28561 (Scan_Make_Arg): Add the executable suffix only if the argument
28562 following -o, in canonical case, does not end with the executable
28563 suffix. When in verbose mode and executable file name does not end
28564 with executable suffix, output the executable name, in canonical case.
28566 * s-tataat.ads (Access_Dummy_Wrapper): Add pragma No_Strict_Aliasing
28567 to avoid warnings when instantiating Ada.Task_Attributes.
28570 * mlib-prj.adb (Process_Imported_Libraries): Get the imported libraries
28571 in the correct order.
28573 * prj-makr.adb (Process_Directory): No longer use GNAT.Expect, but

28578 directory, instead of the Value.
28579 (Find_Source_Dirs): Remove useless code & comments.
28581 2004-03-15 Ed Schonberg <schonberg@gnat.com>
28583 * exp_ch3.adb (Freeze_Record_Type): If a primitive operation of a
28584 tagged type is inherited, and the parent operation is not frozen yet,
28585 force generation of a freeze node for the inherited operation, so the
28586 corresponding dispatch entry is properly initialized.
28587 (Make_Predefined_Primitive_Specs): Check that return type is Boolean
28588 when looking for user-defined equality operation.
28590 * exp_ch4.adb (Expand_Composite_Equality): Check that return type is
28591 boolean when locating primitive equality of tagged component.
28593 * exp_ch5.adb (Expand_Assign_Array): If the left-hand side is a
28594 bit-aligned field and the right-hand side a string literal, introduce
28595 a temporary before expanding assignment into a loop.
28597 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Copy expression for
28598 priority in full, to ensure that any expanded subepxressions of it are
28599 elaborated in the scope of the init_proc.
28601 * exp_prag.adb (Expand_Pragma_Import): Search for initialization call
28602 after object declaration, skipping over code that may have been
28603 generated for validity checks.
28605 * sem_ch12.adb (Validate_Private_Type_Instance): If type has unknown
28606 discriminants, ignore the known discriminants of its full view, if
28607 any, to check legality.
28609 * sem_ch3.adb (Complete_Private_Subtype): Do not create constrained
28610 component if type has unknown discriminants.
28611 (Analyze_Private_Extension_Declaration): Discriminant constraint is
28612 null if type has unknown discriminants.
28614 * sem_ch6.adb (Analyze_Generic_Subprogram_Body): Generate reference
28615 for end label when present.
28617 * s-fileio.adb (Open): When called with a C_Stream, use given name for
28618 temporary file, rather than an empty string.
28620 2004-03-15 Ed Falis <falis@gnat.com>
28622 * s-thread.adb: Removed, no longer used.
28624 2004-03-15 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>

28644 * exp_ch4.adb (Expand_N_Indexed_Component): Do not call
28645 Insert_Dereference_Action when rewriting an implicit dereference into
28646 an explicit one, this will be taken care of during expansion of the
28647 explicit dereference.
28648 (Expand_N_Slice): Same. Always do the rewriting, even for the case
28649 of non-packed slices, since the dereference action generated by
28650 expansion of the explicit dereference is needed in any case.
28651 (Expand_N_Selected_Component): When rewriting an implicit dereference,
28652 analyze and resolve the rewritten explicit dereference so it is seen
28654 (Insert_Dereference_Action): This procedure is now called only for the
28655 expansion of an N_Explcit_Dereference_Node. Do insert a check even for
28656 dereferences that do not come from source (including explicit
28657 dereferences resulting from rewriting implicit ones), but do not
28658 recursively insert a check for the dereference nodes contained within
28660 (Insert_Dereference_Action): Clarify and correct comment.

29537 checks for bitfield creation are triggered.
29538 (finish_record_type): During last pass over the fields, clear

29879 2004-01-12 Ed Schonberg <schonberg@gnat.com>
29881 * lib-xref.adb (Get_Type_Reference): If the type is the subtype entity
29882 generated to rename a generic actual, go to the actual itself, the
29883 subtype is not a user-visible entity.
29885 * sem_ch7.adb (Uninstall_Declarations): If an entity in the visible
29886 part is a private subtype, reset the visibility of its full view, if
29887 any, to be consistent.
29890 * sem_ch12.adb (Analyze_Formal_Package): Diagnose properly an attempt

29923 2004-01-05 Robert Dewar <dewar@gnat.com>
29925 * 1ssecsta.ads: Default_Secondary_Stack is not a constant since it may
29926 be modified by the binder generated main program if the -D switch is
29929 * 4onumaux.ads, 4znumaux.ads: Add Pure_Function pragmas for all
29930 imported functions (since now we expect this to be done for imported

29942 * sprint.adb: Minor updates to avoid -gnatwa warnings
29944 * s-secsta.ads, s-secsta.adb:
29945 (SS_Get_Max): New function to obtain high water mark for ss stack
29946 Default_Secondary_Stack is not a constant since it may be modified by
29947 the binder generated main program if the -D switch is used.
29949 * switch-b.adb: New -Dnnn switch for binder
29952 Make -gnatg imply all warnings currently in -gnatwa

29991 * bindusg.adb: Add line for new -D switch
29993 * exp_aggr.adb (Type_May_Have_Bit_Aligned_Components): More appropriate
29994 replacement name for Type_May_Have_Non_Bit_Aligned_Components!
29995 Add circuitry for both records and arrays to avoid gigi
29996 processing if the type involved has non-bit-aligned components
29998 * exp_ch5.adb (Expand_Assign_Array): Avoid assumption that
29999 N_String_Literal node always references an E_String_Literal_Subtype
30000 entity. This may not be true in the future.
30001 (Possible_Bit_Aligned_Component): Move processing of
30002 Component_May_Be_Bit_Aligned from exp_ch5 to exp_util
30004 * exp_ch6.adb (Expand_Thread_Body): Pick up
30005 Default_Secondary_Stack_Size as variable so that we get value modified
30006 by possible -Dnnn binder parameter.
30008 * exp_util.adb (Component_May_Be_Bit_Aligned): New function.
30009 (Type_May_Have_Bit_Aligned_Components): New function.
30011 * exp_util.ads (Component_May_Be_Bit_Aligned): New function.

30044 * rtsfind.adb (Load_Fail): Give full error message in configurable
30045 run-time mode if all_errors mode is set. This was not done in the case
30046 of a file not found, which was an oversight.
30047 Note if secondary stack unit is used by compiler.
30049 * sem_elab.adb (Check_A_Call): Rewrite to avoid trying to put
30050 ineffective elaborate all pragmas on non-visible packages (this
30051 happened when a renamed subprogram was called). Now the elaborate all
30052 always goes on the package containing the renaming rather than the one
30053 containing the renamed subprogram.
30055 * sem_elim.ads, sem_elim.adb (Eliminate_Error_Msg): New procedure
30056 (Process_Eliminate_Pragma): Add parameter to capture pragma location.

30059 has an Etype that references an E_String_Literal.
30060 (Eval_String_Literal): Avoid assumption that N_String_Literal node
30061 always references an E_String_Literal_Subtype entity. This may not
30062 be true in the future.

30067 * sem_res.adb (Resolve): Specialize msg for function name used in proc
30070 2004-01-05 Ed Falis <falis@gnat.com>

30078 (Process_Declarative_Items): Correct incorrect name (Index_Name instead
30081 * make.adb (Gnatmake): Special process for files to compile/check when
30082 -B is specified. Fail when there are only foreign mains in attribute
30083 Main of the project file and -B is not specified. Do not skip bind/link
30084 steps when -B is specified.

30109 -gnatwa warning on static condition.
30111 2004-01-05 Doug Rupp <rupp@gnat.com>

30115 2004-01-05 Arnaud Charlet <charlet@act-europe.fr>
30117 * Makefile.in: Install ali files using INSTALL_DATA_DATE to preserve
30118 all attributes, including read-only attribute.
30120 2004-01-05 Pascal Obry <obry@gnat.com>

30123 library naming scheme.
30125 * mlib-prj.adb (Build_Library): Generate different names for the static
30126 or dynamic version of the GNAT runtime. This is needed to support the

30129 based on the new naming scheme.
30131 * gnatlink.adb (Process_Binder_File): Properly detect the new naming
30132 scheme for the shared runtime libraries.
30135 (LIBRARY_VERSION) [VMS]: Convert all . to _ to conform to new naming
30137 (install-gnatlib): Do not create symlinks for shared libraries.
30138 (gnatlib-shared-default): Idem.
30139 (gnatlib-shared-dual-win32): New target. Not used for now as the
30140 auto-import feature does not support arrays/records.
30141 (gnatlib-shared-win32): Do not create copy for the shared libraries.
30142 (gnatlib-shared-vms): Fix shared runtime libraries names.
30144 * osint.ads, osint.adb (Shared_Lib): New routine, returns the target
30145 dependent runtime shared library name.
30147 2004-01-05 Vasiliy Fofanov <fofanov@act-europe.fr>
30149 * osint.adb (Read_Library_Info): Remove bogus check if ALI is older
30152 2004-01-05 Ed Schonberg <schonberg@gnat.com>
30154 * sem_ch4.adb (Analyze_Allocator): Check restriction on dynamic
30155 protected objects when allocator has a subtype indication, not a
30156 qualified expression. Note that qualified expressions may have to be
30157 checked when limited aggregates are implemented.
30159 * sem_prag.adb (Analyze_Pragma, case Import): If enclosing package is
30160 pure, emit warning.
30161 (Analyze_Pragma, case Pure_Function): If enclosing package is pure and
30162 subprogram is imported, remove warning.
30164 2004-01-05 Geert Bosch <bosch@gnat.com>
30166 * s-poosiz.adb: Update copyright notice.
30167 (Allocate): Use Task_Lock to protect against concurrent access.

30206 * cstand.adb (Create_Standard): Change the way how the declaration of
30207 the Duration type is created (making it the same way as it is for all
30208 the other standard types).
30210 2003-12-17 Robert Dewar <dewar@gnat.com>

30220 * sem_ch3.adb (Constrain_Index): Handle properly a range whose bounds
30221 are universal and already analyzed, as can occur in constrained
30222 subcomponents that depend on discriminants, when one constraint is a

30307 Minor reformatting throughout
30309 2003-12-11 Ed Schonberg <schonberg@gnat.com>
30311 * exp_ch7.adb (Establish_Transient_Scope): If the call is within the
30312 bounds of a loop, create a separate block in order to generate proper
30313 cleanup actions to prevent memory leaks.
30315 * sem_res.adb (Resolve_Call): After a call to
30316 Establish_Transient_Scope, the call may be rewritten and relocated, in
30317 which case no further processing is needed.
30319 * sem_util.adb: (Wrong_Type): Refine previous fix.
30320 Fixes ACATS regressions.
30323 * sem_prag.adb (Back_End_Cannot_Inline): A renaming_as_body can always

30332 * Makefile.in: (rts-ravenscar): Generate an empty libgnat.a.
30335 2003-12-08 Robert Dewar <dewar@gnat.com>
30337 * 7sintman.adb: Minor reformatting
30339 * bindgen.adb: Configurable_Run_Time mode no longer suppresses the
30340 standard linker options to get standard libraries linked. We now plan
30341 to provide dummy versions of these libraries to match the appropriate
30342 configurable run-time (e.g. if a library is not needed at all, provide
30343 a dummy empty library).
30345 * targparm.ads: Configurable_Run_Time mode no longer affects linker
30346 options (-L parameters and standard libraries). What we plan to do is
30347 to provide dummy libraries where the libraries are not required.
30349 * gnatbind.adb: Minor comment improvement
30351 2003-12-08 Javier Miranda <miranda@gnat.com>
30353 * exp_aggr.adb (Build_Record_Aggr_Code): Do not remove the expanded
30354 aggregate in the parent. Otherwise constants with limited aggregates

30775 the range of Keep_Unmasked (in procedure Interrupt_Self_Process). The
30776 reason is that the index type of the Keep_Unmasked array is not always

34183 (title page): Remove date.
34184 (general) Add @./@: where approriate, and two spaces after the
34185 full stop at the end of a sentence. Use @samp markup when
34186 referring concrete lexical entities (keywords, attribute names
34187 etc.), and @syntax for ARM grammar elements. Use @r for English

34200 2001-12-22 Florian Weimer <fw@deneb.enyo.de>
34202 * make.adb (Add_Switch): Make Generic_Position a procedure. The
34203 function approach did not work well because of a side effect (the
34204 function call could reallocate the table which was being indexed
34205 using its result). Fixes ada/4851.

34264 Add 2001 to copyright date
34266 * g-regpat.adb: Change pragma Inline_Always to Inline. There is no
34267 need to force universal inlining for these cases.
34269 2001-12-19 Arnaud Charlet <charlet@gnat.com>
34271 * s-taprob.adb: Minor clean ups so that this unit can be used in

34298 the argument of an initialization procedure.
34300 * trans.c (tree_transform, case of arithmetic operators): If result
34301 type is private, the gnu_type is the base type of the full view,

34390 Compute_Length and Determine_Range.
34391 Above changes fix problem with length computation for supernull arrays
34392 where Max (Len, 0) wasn't getting applied due to the Unsigned
34393 conversion used by Compute_Length.

34483 When using a project file, fail if specified executable is relative
34484 path with directory information, and prepend executable, if not
34485 specified as an absolute path, with the exec directory. Make sure
34486 that only one -o switch is transmitted to the linker.
34488 * prj-attr.adb (Initialization_Data): Add project attribute Exec_Dir

34569 there could be a real problem here with an uninitialized reference
34570 to Hbound, but no actual example of failure has been found.
34572 2001-12-17 Laurent Pautet <pautet@gnat.com>
34575 Fix comment of Shutdown_Socket and Close_Socket. These functions
34576 should not fail silently because if they are called twice, this
34577 probably means that there is a race condition in the user program.
34578 Anyway, this behaviour is consistent with the rest of this unit.
34579 When an error occurs, an exception is raised with the error message
34580 as exception message.
34582 2001-12-17 Robert Dewar <dewar@gnat.com>

35919 (Get_File_Checksum): renamed Get_File_CRC as now we compute CRC
35920 instead of simple checksum.
35921 (CRC_Match): new function.
35922 (CRC_Error): new constant.
35924 * ali.adb (Scan_ALI): rename variable Chk to CRC as we are handling
35925 a CRC now and not a simple checksum. A CRC uses lower-case hex
35926 letters, fixes ambiguity in parsing.
35928 * ali.ads (Sdep_Record.Checksum): renamed Sdep_Record.CRC as this
35929 is what this variable will store.
35931 * bcheck.adb: Change reference to chechsum in comments by CRC.
35932 (Check_Consistency): Rename Get_File_Checksum to Get_File_CRC.
35933 rename All_Checksum_Match to All_CRC_Match. Change due to API
35934 renaming since now GNAT does not use a simple checksum but a
35935 CRC using GNAT.CRC32.
35937 * gnatls.adb: Rename Checksum to CRC in many places, we use a CRC
35938 now and not anymore a simple checksum.

35977 * types.adb (Hex): Use lowercase for the letter part.
35979 * types.ads (Get_Hex_String): Returns the hexadecimal representation
35980 for a word. This is currently used only for CRC. In previous version,
35981 the checksum was using a representation with all letter being
35982 upper-case. With the new implementation (using CRC) we do not remove
35983 the 32th bit of the CRC, so we can have an upper-case starting letter
35984 in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
35985 It is ambigous since the CRC was optional and could be followed by
35986 options like EB, EE. So now this routines uses lower-case letter for
35987 the hexadecimal representation. Strange enough only lower case letters
35988 where checked in Scan_ALI (even if this was not a possible case).
35990 * gnatvsn.ads (Library_Version): changed to 3.15a.
35992 * s-crc32.ads: Initial version from GNAT.CRC32. This is the version
35995 * s-crc32.adb: Initial version from GNAT.CRC32. This is the version
