8 * exp_ch4.adb (Expand_N_Allocator): If the designated type
9 is a private derived type with no discriminants, examine its
10 underlying_full_view to determine whether the full view has

60 2016-05-02 Ed Schonberg <schonberg@adacore.com>
62 * exp_prag.adb (Expand_attributes_In_Consequence,
63 Expand_Attributes): If the prefix of'Old is an unconstrained type,
64 for example an unconstrained formal of the enclosing subprogram,
65 create an object declaration with an expression to obtain the

169 as yet another scopes.
170 (Enclosing_Subprogram_Or_Library_Package): refactored using
171 Hristian's suggestions; added support for scopes of protected
172 types and bodies; fix for entries to return the scope of the
173 enclosing concurrent type, which is consistent with what is
174 returned for protected subprograms.
175 * sem_intr.adb: Minor style fix in comment.
177 2016-05-02 Hristian Kirtchev <kirtchev@adacore.com>

246 2016-05-02 Ed Schonberg <schonberg@adacore.com>
248 * sem_util.adb (Normalize_Actuals): Take into account extra
249 actuals that may have been introduced previously. Normally extra
250 actuals are introduced when a call is expanded, but a validity
251 check may copy and reanalyze a call that carries an extra actual
252 (e.g. an accessibility parameter) before the call itself is
253 marked Analzyed, and the analysis of the copy has to be able to
254 cope with the added actual.

265 record cases, apply predicate check on component for expression
266 only if expression has been analyzed already. For expressions
267 that need to be duplicated when they cover multiple components,
268 resolution and predicate checking take place later.
270 2016-05-02 Olivier Hainque <hainque@adacore.com>
272 * a-direct.adb (Delete_Tree): Use full names to designate subdirs
273 and files therein, instead of local names after a change of

299 * usage.adb, switch-c.adb: Disable support for -gnatxx under this flag.
300 * einfo.ads (Has_Predicates, Predicate_Function):
301 Clarify that Has_Predicates does not imply that Predicate_Function
302 will return a non-empty entity.
304 2016-05-02 Ed Schonberg <schonberg@adacore.com>
306 * sem_res.adb (Resolve_Qualified_Expression): Generate a predicate
307 check if type requires it.
308 * checks.adb (Apply_Predicate_Check): Disable checks in the
309 object declaration created for an expression with side-effects
310 that requires a predicate check to prevent infinite recursion
313 2016-05-02 Ed Schonberg <schonberg@adacore.com>
315 * sem_ch6.adb (Process_Formals): Check properly the type of a
316 formal to determine whether a given convention applies to it.

322 2016-05-02 Thomas Quinot <quinot@adacore.com>
324 * freeze.adb (Check_Component_Storage_Order): Make it a warning, not an
325 error, to have a component with implicit SSO within a composite type
326 that has explicit SSO.
328 2016-05-02 Bob Duff <duff@adacore.com>
330 * s-stposu.adb (Allocate_Any_Controlled): Don't lock/unlock twice.

350 2016-05-02 Ed Schonberg <schonberg@adacore.com>
352 * sem_ch4.adb (Analyze_Allocator): If the expression does not
353 have a subtype indication and the type is an unconstrained tagged
354 type with defaulted discriminants, create an explicit constraint
355 for it during analysis to prevent out-of-order freezing actions
356 on generated classwide types.
358 2016-05-02 Javier Miranda <miranda@adacore.com>
360 * exp_ch5.adb (Expand_N_Assignment_Statement):
361 In the runtime check that ensures that the tags of source an
362 target match, add missing displacement of the pointer to the
363 objects if they cover interface types.
365 2016-05-02 Ed Schonberg <schonberg@adacore.com>
367 * sem_attr.adb (Analyze_Attribute, case 'Old): Do not use
368 base type for attribute when type is discrete: transformation
369 is not needed for such types, and leads to spurious errors if
370 the context is a case construct.

435 Do not special-case the type_annotate_only mode. Call
436 gnat_to_gnu_profile_type instead of gnat_to_gnu_type on return type.
437 Deal with dummy return types. Likewise for parameter types. Deal
438 with by-reference types explicitly and add a kludge for null procedures
439 with untagged incomplete types. Remove assertion on the types and be
440 prepared for multiple elaboration of the declarations. Skip the whole

808 * sem_ch5.adb (Analyze_Block_Statement): check useless
809 assignements in declaration blocks as part of processing their

1044 * sem_ch13.adb (Add_Predicates): if the type is declared in
1045 an inner package it may be frozen outside of the package, and
1046 the generated pragma has not been analyzed yet, the expression
1047 for the predicate must be captured and added to the predicate
1048 function at this point.

1052 * contracts.adb (Analyze_Package_Body_Contract): Do not check
1053 for a missing package refinement because 1) packages do not have
1054 "refinement" and 2) the check for proper state refinement is
1055 performed in a different place.

1127 * lib-writ.adb (Write_ALI): Do not record in ali file units
1128 that are present in the files table but not analyzed. These
1129 units are present because they appear in the context of units
1130 named in limited_with clauses, and the unit being compiled does
1131 not depend semantically on them.
1133 2016-04-21 Ed Schonberg <schonberg@adacore.com>
1135 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Simplify code to
1136 create the procedure body for an function returning an array type,
1137 when generating C code. Reuse the subprogram body rather than
1138 creating a new one, both as an efficiency measure and because
1139 in an instance the body may contain global references that must

1226 of a generic subpprogram that carries an Inline aspect. Place
1227 inline info on the anonymous subprogram that is constructed in
1228 the wrapper package.
1229 (Analyze_Pragma, case Pure): Do not check placement if pragma
1230 appears within an instantiation, which can be nested at any level.
1231 * sem_ch12.adb (Analyze_Instance_And_Renamings): Do not copy Freeze

1258 (Has_Non_Null_Abstract_State): New routine.
1259 * sem_ch7.adb (Unit_Requires_Body): Add local variable
1260 Requires_Body. A package declaring an abstract state requires
1261 a body only when the state is non-null and the package contains
1262 at least one other construct that requires completion in a body.

1298 2016-04-21 Ed Schonberg <schonberg@adacore.com>
1300 * sem_ch8.adb (Find_Selected_Component): If prefix has an
1301 access type and designated type is a limited view, introduce
1302 an explicit dereference before continuing the analysis, and
1303 set its type to the non-limited view of the designated type,
1304 if we are in context where it is available.
1306 2016-04-21 Ed Schonberg <schonberg@adacore.com>

1325 * freeze.ads, freeze.adb (Freeze_Entity, Freeze_Before): Add
1326 boolean parameter to determine whether freezing an overloadable
1327 entity freezes its profile as well. This is required by
1328 AI05-019. The call to Freeze_Profile within Freeze_Entity is
1329 conditioned by the value of this flag, whose default is True.
1330 * sem_attr.adb (Resolve_Attribute, case 'Access): The attribute
1331 reference freezes the prefix, but it the prefix is a subprogram
1332 it does not freeze its profile.
1334 2016-04-21 Javier Miranda <miranda@adacore.com>
1336 * exp_util.adb (Build_Procedure_Form): No action needed for
1337 subprogram renamings since the backend can generate the call

1350 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): If the body is
1351 created for SPARK_To_C, the entity must remain invisible so it
1352 does not overload subsequent references to the original function.
1353 * exp_ch6.adb (Build_Procedure_Body_Form, Replace_Returns):
1354 Handle Extended_Return_Statements by replacing it with a block
1355 with assignments and a simple return statement.

1362 * sem_ch6.adb (Build_Subprogram_Declaration): Propagate the
1363 attribute Rewritten_For_C to the body since since the expander
1364 may generate calls using that entity.
1365 * exp_ch6.adb (Expand_Call): For internally generated
1366 calls ensure that they reference the entity of the spec
1367 of the called function.

1447 * sem_ch13.adb (Build_Predicate_Function_Declaration): New
1448 function, to construct the declaration of a predicate function
1449 at the end of the current declarative part rather than at the
1450 (possibly later) freeze point of the type. This also allows uses
1451 of a type with predicates in instantiations elsewhere.
1452 (Resolve_Aspect_Expression): New procedure to detect visiblity
1453 errors in aspect expressions, at the end of the declarative part
1454 that includes the type declaration.
1455 * sem_ch3.adb (Complete_Private_Subtype): Propagate properly the
1456 predicate function from private to full view.
1457 * einfo.adb (Predicate_Function): Refine search for predicate

1461 2016-04-20 Javier Miranda <miranda@adacore.com>
1463 * frontend.adb: Passing the root of the tree to
1464 Unnest_Subprograms().
1465 * exp_ch6.adb (Expand_N_Subprogram_Body): Remove code that
1466 took care of adding subprograms to the Unest_Bodies table since
1467 performing such action too early disables the ability to process
1468 generic instantiations.

1490 * sem_ch6.adb (Enter_Overloaded_Entity): Do not warn about
1491 hiding unless we're actually hiding something. The previous
1492 code would (for example) warn about a "<" on a record type
1493 because it incorrectly thought it was hiding the "<" on Boolean
1494 in Standard. We need to check that the homonym S is in fact a
1495 homograph of a predefined operator.
1497 2016-04-20 Ed Schonberg <schonberg@adacore.com>
1499 * exp_util.ads, exp_util.adb (Build_Procedure_Form): Moved here
1500 from exp_ch6.adb, for use in SPARK_To_C mode when creating the

1503 * sem_util.adb (Is_Unchecked_Conversion_Instance): Include a
1504 function that renames an instance of Unchecked_Conversion.
1505 * freeze.adb (Freeze_Subprogram): Generate the proper procedure
1506 declaration for a function returning an array.
1507 * exp_ch6.adb (Build_Procedure_Form): Moved to exp_util.
1509 2016-04-20 Ed Schonberg <schonberg@adacore.com>
1511 * sem_util.ads, sem_util.adb (Is_Expanded_Priority_Attribute):
1512 New predicate to determine that in a context with full run-time,
1513 a function call is an expansion of a reference to attribute

1552 * sem_ch4.adb (Analyze_Selected_Component): A reference to the
1553 current instance of a task type is legal if the prefix is an
1554 expression of that task type and the selector is an entry or
1557 2016-04-20 Arnaud Charlet <charlet@adacore.com>
1559 * a-cfdlli.ads (List): Type is no longer tagged, not needed. Move

2081 2016-04-18 Yannick Moy <moy@adacore.com>
2083 * sem_eval.adb, sem_eval.ads (Check_Non_Static_Context): Add
2084 comment to document usage of subprogram in GNATprove.
2086 2016-04-18 Ed Schonberg <schonberg@adacore.com>
2088 * sem_prag.adb (Analyze_Pragma, case Test_Case): Improve error
2089 message for wrong placement of aspect Test_Case.
2091 2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
2093 * einfo.ads: Update the documentation of attribute Renamed_Object.
2094 * exp_spark.adb (Expand_Potential_Renaming): Reimplemented.
2096 2016-04-18 Gary Dismukes <dismukes@adacore.com>
2098 * exp_ch4.adb (Optimize_Length_Comparison): Return immediately
2099 in the case of AAMP (same as for use of the -gnatd.P switch) to
2100 suppress this optimization, which avoids creating a dependence
2101 on the 64-bit arithmetic package.
2103 2016-04-18 Arnaud Charlet <charlet@adacore.com>
2105 * exp_ch4.adb: Update comment.
2107 2016-04-18 Eric Botcazou <ebotcazou@adacore.com>
2109 * exp_ch6.adb (Expand_Call): Make sure instantiations are
2110 registered only once as pending here.
2112 2016-04-18 Arnaud Charlet <charlet@adacore.com>
2114 * exp_ch4.adb, gnat1drv.adb, opt.ads, sem_res.adb
2115 (Minimize_Expression_With_Actions): New flag.
2116 (Adjust_Global_Switches): Set Minimize_Expression_With_Actions
2118 (Resolve_Short_Circuit): Redo previous change
2119 using Minimize_Expression_With_Actions.
2120 (Expand_N_If_Expression,
2121 Expand_Short_Circuit_Operator): Restore old code to avoid
2122 Expression_With_Actions when Minimize_Expression_With_Actions
2125 2016-04-18 Vincent Celier <celier@adacore.com>
2127 * s-os_lib.adb (Non_Blocking_Spawn, version with Stdout_File and
2128 Stderr_File): Close local file descriptors when no longer needed.
2130 2016-04-18 Ed Schonberg <schonberg@adacore.com>
2132 * sem_ch5.adb (Analyze_Iterator_Specification): Remove SPARK
2133 mode check that the type of the cursor in an iteration over
2134 a formal container is not volatile. The proper check on the
2135 element type is done elsewhere.
2137 2016-04-18 Ed Schonberg <schonberg@adacore.com>
2139 * sem_ch6.adb (Process_Formals): Do not set a delay freeze on
2140 a subprogram that returns a class-wide type, if the subprogram
2141 is a compilation unit, because otherwise gigi will treat the
2142 subprogram as external, leading to link errors.
2144 2016-04-18 Arnaud Charlet <charlet@adacore.com>
2146 * sem_res.adb (Resolve_Short_Circuit): Do not use
2147 expression-with-actions when generating C.
2149 2016-04-18 Yannick Moy <moy@adacore.com>
2151 * sem_util.adb (Apply_Compile_Time_Constraint_Error): Do not generate
2152 raise node in GNATprove mode.
2154 2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
2156 * s-fileio.adb: Minor reformatting.
2157 * sem_prag.adb (Analyze_Input_Item): Add local
2158 variable Input_OK. Do not consider mappings of generic formal
2159 parameters to actuals.
2161 2016-04-18 Ed Schonberg <schonberg@adacore.com>
2163 * sem_ch5.adb (Get_Cursor_Type): If iterator type is a derived
2164 type, the cursor is declared in the scope of the parent type.
2165 (Analyze_Parameter_Specification): A qualified expression with an
2166 iterator type indicates an iteration over a container (explicit
2169 2016-04-18 Arnaud Charlet <charlet@adacore.com>
2171 * osint-c.ads, osint-c.adb (Delete_C_File, Delete_H_File): New.
2172 * gnat1drv.adb (Gnat1drv): Delete old C files before regenerating them.
2173 * debug.adb: Reserve -gnatd.4 to force generation of C files.
2175 2016-04-18 Yannick Moy <moy@adacore.com>
2177 * sem_eval.adb (Eval_Arithmetic_Op): Do not issue error on static
2178 division by zero, instead possibly issue a warning.
2179 * sem_res.adb (Resolve_Arithmetic_Op): Do not issue error on
2180 static division by zero, instead add check flag on original
2182 * sem_util.adb, sem_util.ads (Compile_Time_Constraint_Error):
2183 Only issue error when both SPARK_Mode is On and Warn is False.
2185 2016-04-18 Yannick Moy <moy@adacore.com>
2187 * checks.adb (Apply_Scalar_Range_Check): Force
2188 warning instead of error when SPARK_Mode is On, on index out of
2189 bounds, and set check flag for GNATprove.
2191 2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
2193 * sem_prag.adb (Check_In_Out_States.Check_Constituent_Usage):
2194 Update the comment on usage. Reimplemented.
2195 (Check_Input_States.Check_Constituent_Usage): Update the comment
2196 on usage. A Proof_In constituent can now refine an Input state
2197 as long as there is at least one Input constituent present.
2199 2016-04-18 Ed Schonberg <schonberg@adacore.com>
2201 * sem_ch6.adb (Check_Inline_Pragma): Use the Sloc of the
2202 body id as the sloc of the entity in the generated subprogram
2203 declaration, to avoid spurious conformance errors when style
2206 2016-04-18 Ed Schonberg <schonberg@adacore.com>
2208 * sem_ch4.adb (Analyze_Selected_Component, Has_Dereference):
2209 Refine check on illegal calls to entities within a task body,
2210 when the entity is declared in an object of the same type. In
2211 a generic context there might be no explicit dereference but if
2212 the prefix includes an access type the construct is legal.
2214 2016-04-18 Arnaud Charlet <charlet@adacore.com>
2216 * rtsfind.ads, rtsfind.adb (RE_Id, RE_Unit_Table): add
2217 RE_Default_Priority.
2219 2016-04-18 Bob Duff <duff@adacore.com>
2221 * sem_prag.adb (Check_Arg_Is_Local_Name): Don't do the check
2222 if the pragma came from an aspect specification.
2224 2016-04-18 Gary Dismukes <dismukes@adacore.com>
2226 * gnat1drv.adb, contracts.adb: Minor reformatting and wording fixes.
2228 2016-04-18 Ed Schonberg <schonberg@adacore.com>
2230 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): To suppress
2231 superfluous conformance check on an inlined body with a previous
2232 spec, use the fact that the generated declaration does not come
2233 from source. We must treat the entity as coming from source to
2234 enable some back-end inlining when pragma appears after the body.
2236 2016-04-18 Gary Dismukes <dismukes@adacore.com>
2238 * lib-xref-spark_specific.adb, par-ch2.adb, errout.ads,
2239 exp_intr.adb: Minor reformatting and typo corrections.
2241 2016-04-18 Ed Schonberg <schonberg@adacore.com>
2243 * sem_ch6.adb: Code cleanup.
2245 2016-04-18 Thomas Quinot <quinot@adacore.com>
2247 * sem_ch13.adb: Minor reformatting and error message tweaking
2248 (remove extraneous spaces).
2250 2016-04-18 Johannes Kanig <kanig@adacore.com>
2252 * gnat1drv.adb (Gnat1drv): Force loading of System unit for SPARK.
2254 2016-04-18 Bob Duff <duff@adacore.com>
2256 * s-fileio.adb (Fopen_Mode): If Mode = Out_File, and the file
2257 exists, and it's a fifo, we use "w" as the open string instead of
2258 "r+". This is necessary to make a write to the fifo block until
2261 2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
2263 * sem_attr.adb (Denote_Same_Function): Account
2264 for a special case where a primitive of a tagged type inherits
2265 a class-wide postcondition from a parent type.
2267 2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
2269 * par-ch2.adb (P_Expression_Or_Reserved_Word): New routine.
2270 (P_Pragma): Signal Scan_Pragma_Argument_Association when the use
2271 of reserved words is OK.
2272 (Scan_Pragma_Argument_Association):
2273 Add new formal Reserved_Words_OK and update the comment on
2274 usage. Code cleanup. Parse an expression or a reserved word in
2275 identifier form for pragmas Restriction_Warnings and Restrictions
2276 No_Use_Of_Attribute.
2277 * restrict.adb (Check_Restriction_No_Use_Of_Attribute):
2278 Reimplemented. (Check_Restriction_No_Use_Of_Pragma): Code cleanup.
2279 (Set_Restriction_No_Specification_Of_Aspect): Properly set the warning
2281 (Set_Restriction_No_Use_Of_Attribute): Properly set the warning
2282 flag for an attribute. (Set_Restriction_No_Use_Of_Entity):
2283 Update the parameter profile.
2284 (Set_Restriction_No_Use_Of_Pragma): Properly set the warning flag for
2286 * restrict.ads (Check_Restriction_No_Use_Of_Attribute): Update
2287 the comment on usage.
2288 (Set_Restriction_No_Use_Of_Entity): Update the parameter profile.
2289 * sem_attr.adb (Analyze_Attribute): Check restriction
2290 No_Use_Of_Attribute.
2291 * sem_ch13.adb (Analyze_Attribute_Definition_Clause): Check
2292 restriction No_Use_Of_Attribute before any rewritings have
2294 * sem_prag.adb (Analyze_Pragma): Check restriction
2295 No_Use_Of_Pragma before any rewritings have taken place.
2297 2016-04-18 Bob Duff <duff@adacore.com>
2299 * sem_ch6.adb (Is_Inline_Pragma): The pragma
2300 argument can be a selected component, which has no Chars field,
2301 so we need to deal with that case (use the Selector_Name).
2302 (Check_Inline_Pragma): We need to test Is_List_Member before
2303 calling In_Same_List, because in case of a library unit, they're
2304 not in lists, so In_Same_List fails an assertion.
2306 2016-04-18 Bob Duff <duff@adacore.com>
2308 * namet.ads, namet.adb: Add an Append that appends a
2309 Bounded_String onto a Bounded_String. Probably a little more
2310 efficient than "Append(X, +Y);". Also minor cleanup.
2311 (Append_Decoded, Append_Decoded_With_Brackets, Append_Unqualified,
2312 Append_Unqualified_Decoded): Make sure these work with non-empty
2314 * casing.ads, casing.adb (Set_Casing): Pass a Bounded_String
2315 parameter, defaulting to Global_Name_Buffer.
2316 * errout.ads, errout.adb (Adjust_Name_Case): Pass a
2317 Bounded_String parameter, no default.
2318 * exp_ch11.adb (Expand_N_Raise_Statement): Use local
2319 Bounded_String instead of Global_Name_Buffer.
2320 * exp_intr.ads, exp_intr.adb (Write_Entity_Name): Rename it
2321 to Append_Entity_Name, and pass a Bounded_String parameter,
2322 instead of using globals.
2323 (Add_Source_Info): Pass a Bounded_String parameter, instead of
2325 (Expand_Source_Info): Use local instead of globals.
2326 * stringt.ads, stringt.adb (Append): Add an Append procedure
2327 for appending a String_Id onto a Bounded_String.
2328 (String_To_Name_Buffer, Add_String_To_Name_Buffer): Rewrite in
2330 * sem_prag.adb (Set_Error_Msg_To_Profile_Name): Adjust for new
2331 Adjust_Name_Case parameter.
2332 * erroutc.adb, uname.adb: Don't pass D => Mixed_Case to
2333 Set_Casing; that's the default.
2334 * lib-xref-spark_specific.adb (Add_SPARK_Scope): Pretend that calls to
2335 protected subprograms are entry calls; otherwise it is not possible to
2336 distinguish them from regular subprogram calls.
2338 2016-04-18 Gary Dismukes <dismukes@adacore.com>
2340 * sem_ch13.adb (Has_Good_Profile): Improvement
2341 of error message. Now indicates subtype_mark of formal parameter
2342 rather than the formal's name, plus minor rewording.
2344 2016-04-18 Pascal Obry <obry@adacore.com>
2346 * adaint.c, adaint.h, s-os_lib.ads: Add new routine Current_Process_Id.
2348 2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
2350 * stringt.adb, exp_ch6.adb, sem_ch13.adb: Minor reformatting.
2352 2016-04-18 Gary Dismukes <dismukes@adacore.com>
2354 * par-ch4.adb, sem_prag.adb: Minor reformatting.
2356 2016-04-18 Bob Duff <duff@adacore.com>
2358 * sinput.ads, sinput.adb (Build_Location_String): Take a
2359 parameter instead of using a global variable. The function
2360 version no longer destroys the Name_Buffer.
2361 * stringt.ads, stringt.adb (String_From_Name_Buffer): Take a
2362 parameter, which defaults to the Global_Name_Buffer, so some
2363 calls can avoid the global.
2364 * exp_ch11.adb, exp_intr.adb: Use new interfaces above
2365 to avoid using globals. All but one call to Build_Location_String
2366 avoids the global. Only one call to String_From_Name_Buffer
2369 2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
2371 * namet.adb, namet.ads, exp_unst.adb: Minor reformatting.
2373 2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
2375 * sem_eval.adb (Choice_Matches): Check the expression
2376 against the predicate values when the choice denotes a
2377 subtype with a static predicate.
2378 (Eval_Membership_Op): Code cleanup. Remove the suspicious guard which
2379 tests for predicates.
2380 (Is_OK_Static_Subtype): A subtype with a dynamic predicate
2381 is not static. (Is_Static_Subtype): A subtype with a dynamic
2382 predicate is not static.
2383 * sem_eval.ads (Is_OK_Static_Subtype): Update the comment on usage.
2384 (Is_Static_Subtype): Update the comment on usage.
2386 2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
2388 * sem_prag.adb (Analyze_Input_Item): Allow
2389 generic formals to appear as initialization items.
2391 2016-04-18 Ed Schonberg <schonberg@adacore.com>
2393 * sem_ch13.adb (Analyze_Stream_TSS_Definition,
2394 Has_Good_Profile): Additional error message to indicate that
2395 the second parameter of the subprogram must be a first subtype.
2397 2016-04-18 Ed Schonberg <schonberg@adacore.com>
2399 * sem_ch6.adb (Analyze_Subprogram_Body_Helper, Is_Inline_Pragma):
2400 Use the pragma lookahead that determines whether a subprogram
2401 is to be inlined, when some level of backend optimization is
2403 * sem_ch12.ads, sem_ch12.adb (Add_Pending_Instantiation): Factorize
2404 code used to create an instance body when needed for inlining.
2405 * exp_ch6.adb (Expand_Call): When a call is to be inlined, and the
2406 call appears within an instantiation that is not a compilation
2407 unit, add a pending instantiation for the enclosing instance,
2408 so the backend can inline in turn the calls contained in the
2411 2016-04-18 Ed Schonberg <schonberg@adacore.com>
2413 * sem_prag.adb (Build_Pragma_Check_Equivalent): The mapping
2414 that relates operations of the parent type to the operations of
2415 the derived type has three distinct sources:
2416 a) explicit operations of the derived type carry an
2417 Overridden_Operation that designates the operation in the
2419 b) Implicit operations that are inherited by the derived type
2420 carry an alias that may be an explicit subprogram (in which case
2421 it may have an Overridden_ Operation indicator) or may also be
2422 inherited and carry its own alias.
2423 c) If the parent type is an interface, the operation of the
2424 derived type does not override, but the interface operation
2425 indicates the operation that implements it.
2426 * sem_prag.adb: Minor reformatting.
2427 * sem_prag.adb (Check_External_Property): Update
2428 the comment on usage. Reimplement.
2430 2016-04-18 Ed Schonberg <schonberg@adacore.com>
2432 * exp_ch5.adb (Expand_Assignment_Statement): In restricted
2433 profiles such as ZFP, ceiling priority is not available.
2435 2016-04-18 Bob Duff <duff@adacore.com>
2437 * namet-sp.ads: Minor typo fix, ironically in 'Spelling_Checker'.
2439 2016-04-18 Bob Duff <duff@adacore.com>
2441 * sem_elab.adb (Output_Calls): Use
2442 Get_Name_String, to clearly indicate that the global Name_Buffer
2443 is being used. The previous code used Is_Internal_Name, which
2444 returns a Boolean, but also has a side effect of setting the
2445 Name_Buffer. Then it called the other Is_Internal_Name, which uses
2446 the Name_Buffer for its input. And then it called Error_Msg_N,
2447 again using the Name_Buffer. We haven't eliminated the global
2448 usage here, but we've made it a bit clearer.
2449 This also allows us to have a side-effect-free version of
2451 * namet.ads, namet.adb: Provide a type Bounded_String, along with
2452 routines that can be used without using global variables. Provide
2453 Global_Name_Buffer so existing code can continue to use the
2454 global. Mark the routines that use globals as obsolete. New code
2455 shouldn't call the obsolete ones, and we should clean up existing
2456 code from time to time.
2457 Name_Find_Str is renamed as Name_Find.
2458 * namet.h: Changed as necessary to interface to the new version
2460 * bindgen.adb, exp_unst.adb: Name_Find_Str is renamed as
2463 2016-04-18 Yannick Moy <moy@adacore.com>
2465 * sem_util.adb, sem_util.ads (Has_Full_Default_Initialization): used
2466 outside of GNATprove, hence it should not be removed.
2468 2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
2470 * sem_prag.adb (Analyze_Refinement_Clause):
2471 The refinement of an external abstract state can now mention
2472 non-external constituents.
2473 (Check_External_Property): Update all SPARK RM references.
2475 2016-04-18 Bob Duff <duff@adacore.com>
2477 * exp_intr.adb: Remove some duplicated code.
2479 2016-04-18 Yannick Moy <moy@adacore.com>
2481 * a-nudira.adb, a-nudira.ads, a-nuflra.adb, a-nuflra.ads: Mark
2482 package spec and body out of SPARK.
2484 2016-04-18 Johannes Kanig <kanig@adacore.com>
2486 * spark_xrefs.ads: Minor comment update.
2488 2016-04-18 Johannes Kanig <kanig@adacore.com>
2490 * gnat1drv.adb (Gnat1drv): Force loading of System
2493 2016-04-18 Bob Duff <duff@adacore.com>
2495 * a-cuprqu.adb: Correction to previous change. If a new node
2496 is inserted at the front of the queue (because it is higher
2497 priority than the previous front node), we need to update
2498 Header.Next_Unequal -- not just in the case where the queue was
2501 2016-04-18 Bob Duff <duff@adacore.com>
2503 * a-cuprqu.ads: Change the representation of List_Type from a
2504 singly-linked list to a doubly-linked list. In addition, add a
2505 pointer Next_Unequal, which points past a possibly-long chain
2506 of equal-priority items. This increases efficiency, especially
2507 in the case of many equal-priority items.
2508 * a-cuprqu.adb (Dequeue, Enqueue): Rewrite algorithms to take
2509 advantage of new data structure.
2510 (Finalize): Rewrite in terms of Dequeue, for simplicity.
2512 2016-04-18 Yannick Moy <moy@adacore.com>
2514 * contracts.adb (Analyze_Object_Contract,
2515 Analyze_Protected_Contract): Remove tests performed in GNATprove.
2516 * sem_util.adb, sem_util.ads (Has_Full_Default_Initialization):
2517 Remove query for tests performed in GNATprove.
2519 2016-04-18 Ed Schonberg <schonberg@adacore.com>
2521 * sem_aggr.adb (Resolve_Record_Aggregate): If
2522 Warn_On_Redundant_Constructs is enabled, report a redundant box
2523 association that does not cover any components, as it done for
2524 redundant others associations in case statements.
2526 2016-04-18 Ed Schonberg <schonberg@adacore.com>
2528 * sem_prag.adb (Collect_Inherited_Class_Wide_Conditions):
2529 Analyze the generated Check pragma for an inherited condition so
2530 that it does not freeze the dispatching type of the primitive
2531 operation, because it is pre-analyzed at the point of the
2532 subprogram declaration (and not in the subprogram body, as is
2533 done during regular expansion).
2535 2016-04-18 Vincent Celier <celier@adacore.com>
2537 * ali.ads: Increase the range of all _Id types to 100 millions.
2539 2016-04-18 Gary Dismukes <dismukes@adacore.com>
2541 * sem_warn.adb (Check_References): Change warning to suggest
2542 using pragma Export rather than saying "volatile has no effect".
2544 2016-04-18 Bob Duff <duff@adacore.com>
2546 * g-souinf.ads (Compilation_ISO_Date): New function to return
2547 the current date in ISO form.
2548 * exp_intr.adb (Expand_Source_Info, Add_Source_Info): Expand
2549 a call to Compilation_ISO_Date into a string literal containing
2550 the current date in ISO form.
2551 * exp_intr.ads (Add_Source_Info): Improve documentation.
2552 * sem_intr.adb (Check_Intrinsic_Subprogram): Recognize
2553 Compilation_ISO_Date.
2554 * snames.ads-tmpl (Name_Compilation_ISO_Date): New Name_Id.
2556 2016-04-18 Eric Botcazou <ebotcazou@adacore.com>
2558 * layout.adb (Set_Elem_Alignment): Extend setting of alignment
2559 to subtypes that are not first subtypes.
2561 2016-04-18 Ed Schonberg <schonberg@adacore.com>
2563 * sem_prag.ads (Collect_Inherited_Class_Wide_Conditions):
2565 * sem_prag.adb (Collect_Inherited_Class_Wide_Conditions): Insert
2566 generated pragmas after subprogram declaration, rather than in
2567 the corresponding subprogram body.
2568 * sem_ch6.adb (New_Overloaded_Entity): In GNATProve
2569 mode, if the operation is overridding, call
2570 Collect_Inherited_Class_Wide_Conditions to generate the
2571 corresponding pragmas immediately after the corresponding
2572 subprogram declaration.
2574 2016-04-18 Arnaud Charlet <charlet@adacore.com>
2576 * spark_xrefs.ads (Xref_Index, Scope_Index, File_Index): restrict
2577 type to natural numbers.
2578 (Stype): document code characters for concurrent entities.
2580 2016-04-18 Olivier Hainque <hainque@adacore.com>
2582 * targparm.ads: Update the Frontend_Exceptions default internal
2584 (Frontend_Exceptions_On_Target): Change default value to True.
2586 2016-04-18 Ed Schonberg <schonberg@adacore.com>
2588 * sem_ch4.adb (Analyze_Selected_Component): Refine error
