1096 2017-09-08 Yannick Moy <moy@adacore.com>
1098 * sem_aux.adb, sem_aux.ads (Get_Called_Entity): New function to
1099 return the entity associated with the call.
1100 * sem_util.adb, sem_util.ads (Check_Function_Writable_Actuals):
1101 Replace the internal Get_Function_Id with the new
1102 Sem_Aux.Get_Called_Entity.
1103 (Iterate_Call_Parameters): New
1104 procedure to iterate on formals and actuals at the same time.
1105 * sem_ch12.adb (Analyze_Subprogram_Instantiation):
1106 Set SPARK_Mode from spec when set, for analysis
1107 of instance. Restore after analysis of instance.
1108 (Instantiate_Subprogram_Body): Set SPARK_Mode from body when
1109 set, for analysis of body instance. Restored automatically at
1110 the end of the subprogram.
1111 * gnat1drv.adb (Adjust_Global_Switches): Set
1112 Check_Validity_Of_Parameters to False in GNATprove mode.
1113 * opt.ads (Check_Validity_Of_Parameters): Document switch to
1114 set option.
1116 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
1118 * sem_util.adb (NCT_Tables_In_Use): Move to library level from...
1119 (New_Copy_Tree): ...there. Reset the hash tables only if they
1120 were used in the previous invocation.
1121 * s-htable.adb: Fix typo.
1123 2017-09-08 Bob Duff <duff@adacore.com>
1125 * a-ssicst.adb (Open): Set File.Last_Op to the appropriate value.
1127 2017-09-08 Arnaud Charlet <charlet@adacore.com>
1129 * sem_aggr.adb: minor style fix.
1131 2017-09-08 Bob Duff <duff@adacore.com>
1133 * sprint.adb (Write_Corresponding_Source): Ignore if there is
1134 no current source file.
1135 (Write_Name_With_Col_Check, Write_Name_With_Col_Check_Sloc):
1136 Print something helpful in case N is invalid.
1137 * sprint.ads: Minor comment fix.
1139 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
1141 * exp_aggr.adb: (Aggr_Assignment_OK_For_Backend): Add early return for
1142 access types.
1144 2017-09-08 Bob Duff <duff@adacore.com>
1146 * par-prag.adb, sem_prag.adb, snames.ads-tmpl: Implement pragma
1147 Ada_2020, along the same lines as the other Ada version pragmas.
1149 2017-09-08 Gary Dismukes <dismukes@adacore.com>
1151 * sem_ch12.adb: Minor typo fixes and reformatting.
1153 2017-09-08 Yannick Moy <moy@adacore.com>
1155 * sem_aggr.adb (Resolve_Record_Aggregate):
1156 Rewrite bounds of aggregate subexpressions which may depend on
1157 discriminants of the enclosing aggregate.
1159 2017-09-08 Yannick Moy <moy@adacore.com>
1161 * sem_ch5.adb: Prevent assertion failure on illegal code.
1163 2017-09-08 Yannick Moy <moy@adacore.com>
1165 * lib-xref-spark_specific.adb (Add_SPARK_Xrefs.Is_SPARK_Scope): Avoid
1166 calling Renamed_Entity on an entity which cannot be a renaming.
1168 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
1170 * exp_aggr.adb: Add with & use clause for Urealp.
1171 (Aggr_Assignment_OK_For_Backend): Accept (almost all)
1172 elementary types instead of just discrete types.
1173 * sem_eval.adb (Expr_Value): Deal with N_Null for access types.
1174 * gcc-interface/trans.c (gnat_to_gnu) <N_Assignment_Statement>:
1175 Be prepared for the FP zero value in the memset case. Add small
1176 guard.
1178 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
1180 * s-htable.adb (Static_HTable.Reset): Use aggregate instead
1181 of loop.
1183 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
1185 * exp_aggr.adb (Expand_Array_Aggregate): Use New_Copy_Tree instead
1186 of New_Copy because the latter leaves the syntactic structure of
1187 the tree inconsistent (a child is accessible through two parents)
1188 and prevents proper replication of itypes by subsequent calls
1189 to New_Copy_Tree.
1190 * exp_ch4.adb (Expand_Concatenate): Use New_Copy_Tree instead of
1191 New_Copy because the latter leaves the syntactic structure of the
1192 tree inconsistent (a child is accessible through two parents)
1193 and prevents proper replication of itypes by subsequent calls
1194 to New_Copy_Tree.
1195 * sem_util.adb (In_Subtree): New routine.
1196 (New_Copy_Tree): Reimplemented.
1197 * sem_util.ads (In_Subtree): New routine.
1198 (New_Copy_Tree): Reimplemented.
1200 2017-09-08 Ed Schonberg <schonberg@adacore.com>
1202 * sem_ch13.adb (Resolve_Aspect_Expressions): The expression
1203 for aspect Default_Value is a static scalar value, but it does
1204 not freeze the type. Yhis allows for subsequent representation
1205 clauses for the type.
1207 2017-09-08 Javier Miranda <miranda@adacore.com>
1209 * sem_ch8.adb (Find_Direct_Name.Undefined): Do
1210 not add entries into the undefined reference table when we are
1211 compiling with errors ignored.
1213 2017-09-08 Ed Schonberg <schonberg@adacore.com>
1215 * sem_ch12.adb (Check_Formal_Packages): Do not apply conformance
1216 check if the instance is within an enclosing instance body. The
1217 formal package was legal in the enclosing generic, and is
1218 legal in the enclosing instantiation. This optimisation may be
1219 applicable elsewhere, and it also removes spurious errors that
1220 may arise with on-the-fly processing of instantiations that
1221 contain Inline_Always subprograms.
1223 2017-09-08 Vincent Celier <celier@adacore.com>
1225 * gnatcmd.adb: Disregard empty argument of GNAT driver.
1227 2017-09-08 Justin Squirek <squirek@adacore.com>
1229 * checks.adb (Insert_Valid_Check): Manually decorate
1230 the generated temporary for range valdity checks.
1232 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
1234 * usage.adb (Usage): Document new -gnatw.q/-gnatw.Q switches.
1236 2017-09-08 Justin Squirek <squirek@adacore.com>
1238 * switch-c.adb (Scan_Front_End_Switches): Add new warning switch
1239 case to handle underscore flags.
1240 * warnsw.adb, warnsw.ads (Set_Underscore_Warning_Switch): Create
1241 new procedure to handle underscores.
1243 2017-09-08 Javier Miranda <miranda@adacore.com>
1245 * exp_ch4.adb (Expand_N_Op_Divide): Reordering code that handles
1246 divisions with fixed point results to avoid generating twice
1247 the runtime check on divide by zero.
1248 * checks.adb (Apply_Divide_Checks): Ensure that operands are
1249 not evaluated twice (once for their runtime checks and once for
1250 their regular computation).
1252 2017-09-08 Yannick Moy <moy@adacore.com>
1254 * sem_prag.adb (Analyze_Part_Of): Add missing
1255 return statements after issuing errors. Add detection of
1256 out-of-order item and single concurrent type.

1360 2017-09-08 Bob Duff <duff@adacore.com>
1362 * s-ststop.ads, s-ststop.adb, rtsfind.ads (String_Input_Tag):
1363 New routine to read the Tag robustly.
1364 * exp_attr.adb (Input): Change the expansion of 'Input,
1365 in the class-wide case, to call String_Input_Tag instead of
1366 String_Input_Blk_IO.
1368 2017-09-08 Arnaud Charlet <charlet@adacore.com>
1370 * s-rident.ads (Restriction_Id): reorder enum
1371 literals, so that Pure_Barriers is no longer in range of the
1372 Cunit_Boolean_Restrictions subtype.
1374 2017-09-08 Nicolas Roche <roche@adacore.com>
1376 * a-taster.ads, a-taster.adb: Move to libgnarl

1378 Add support for files in libgnarl.
1380 2017-09-08 Ed Schonberg <schonberg@adacore.com>
1382 * exp_ch4.adb (Expand_N_Type_Conversion): Do not apply
1383 accessibility check to an interface conversion, whose purpose
1384 is to perform a pointer adjustment in a dispatching call.
1385 * exp_ch6.adb (Expand_Call_JHelper): Add accessibility checks
1386 when the actual is a construct that involves a dereference of an
1387 expression that includes a formal of the enclosing subprogram,
1388 In such cases, the accessibility level of the actual is that of
1389 the corresponding formal, which is passed in as an additional
1390 actual in the outer call.
1392 2017-09-08 Bob Duff <duff@adacore.com>
1394 * exp_intr.adb (Add_Source_Info): Do not decode
1395 file names; they were not encoded in the first place.
1397 2017-09-08 Bob Duff <duff@adacore.com>
1399 * a-tags.adb (Internal_Tag): Unsuppress checks, so we get
1400 exceptions instead of crashes. Check for absurdly long strings
1401 and empty strings. Empty strings cause trouble because they can
1402 have super-null ranges (e.g. 100..10), which causes Ext_Copy to
1403 be empty, which causes an array index out of bounds.
1404 * s-ststop.adb (Input): Unsuppress checks, so we get exceptions
1405 instead of crashes.
1407 2017-09-08 Arnaud Charlet <charlet@adacore.com>
1409 * sem_util.adb (Is_CCT_Instance): allow use in

1449 * sem_util.ads, sem_util.adb: ... here to share it.
1450 (Subprogram_Name): New subprogram, to compute the name of the enclosing
1451 subprogram/entity.
1452 * errutil.adb (Error_Msg): Fill new field Node.
1453 * erroutc.ads (Subprogram_Name_Ptr): New.
1454 (Error_Msg_Object): New field Node.
1455 * erroutc.adb (dmsg, Output_Msg_Text): Take new field Node into account.
1456 * errout.adb (Error_Msg): New variant with node id parameter.
1457 Fill new parameter Node when emitting messages. Revert previous
1458 changes for Include_Subprogram_In_Messages.
1459 * sem_ch5.adb (Check_Unreachable_Code): Supply Node parameter when
1460 generating warning message.
1462 2017-09-08 Ed Schonberg <schonberg@adacore.com>
1464 * par-ch4.adb (P_Iterated_Component_Association): Place construct
1465 under -gnat2020 flag, given that it is a future feature of
1466 the language.
1467 * sem_aggr.adb (Resolve_Iterated_Component_Association): Mark
1468 defining identifier as referenced to prevent spurious warnings:
1469 corresponding loop is expanded into one or more loops whose
1470 variable has the same name, and the expression uses those names
1471 and not the original one.
1473 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>

1545 required for one of the new subprograms.
1546 (Expand_Actuals):

1550 declarations.

1592 2017-09-08 Ed Schonberg <schonberg@adacore.com>
1594 * exp_prag.adb (Replace_Discriminals_Of_Protected_Op):
1595 New procedure, auxiliary to Expand_Pragma_Check, to handle
1596 references to the discriminants of a protected type within a
1597 precondition of a protected operation. This is needed because
1598 the original precondition has been analyzed in the context of
1599 the protected declaration, but in the body of the operation
1600 references to the discriminants have been replaved by references
1601 to the discriminants of the target object, and these references
1602 are only created when expanding the protected body.
1604 2017-09-08 Yannick Moy <moy@adacore.com>

1607 Loop_Variant.

1648 given in the loop specification.
1649 * sem_ch3.adb (Inherit_Predicate_Flags): For qn Itype created for
1650 a loop specification that is a subtype indication whose type mark
1651 is a type with a static predicate, inherit predicate function,
1652 used to build case statement for rewritten loop.

1670 * exp_util.adb (Build_Invariant_Procedure_Declaration): If
1671 the type is an anonymous array in an object declaration, whose
1672 component type has an invariant, use the object declaration
1673 as the insertion point for the invariant procedure, given that
1674 there is no explicit type declaration for an anonymous array type.

1756 decrement Warnings_Treated_As_Errors. This is called before
1757 Warnings_Treated_As_Errors has been incremented to account for
1758 this warning. Decrementing it here can lead to negative values
1759 of Warnings_Treated_As_Errors, raising Constraint_Error in
1760 checks-on builds, and causing the compiler to return an error
1761 code in checks-off builds.
1763 2017-09-08 Arnaud Charlet <charlet@adacore.com>
1765 * sem_util.ads, sem_util.adb (Is_CCT_Instance): Only expect
1766 entities of named concurrent types as Ref_Id and not of anonymous
1767 concurrent objects (because callers already know when a conversion
1768 is necessary and can easily do it); also, do not expect protected
1769 types or protected objects as Context_Id (because no flow-related
1770 SPARK pragmas are attached there); reflect these changes in a
1771 more precise comment.

1787 formal is itself a formal of an enclosing generic.
1789 2017-09-08 Arnaud Charlet <charlet@adacore.com>
1791 * sem_util.ads, sem_util.adb (Is_CCT_Instance): moved from
1792 sem_prag.adb to make it available for GNATprove; for concurrent
1793 types replace custom scope climbing with Scope_Same_Or_Within; for
1794 single concurrent objects add scope climbing (with Scope_Within),
1795 which was not there (that's the primary semantic change of this
1796 commit); also, when comparing a single concurrent object with
1797 its corresponding concurrent type rely on equality of types,
1798 not of objects (because that's simpler to code).
1799 * sem_prag.adb (Is_CCT_Instance): lifted to sem_util.ads.
1800 (Analyze_Global_Item): adjust special-casing of references to the
1801 current instance of a concurrent unit in the Global contracts
1802 of task types and single tasks objects; similar for references
1803 in the protected operations and entries of protected types and
1804 single protected objects (in all these cases the current instance
1805 behaves as an implicit parameter and must not be mentioned in
1806 the Global contract).

1875 of Freeze_Profile, used to inhibit the freezing of the profile
1876 of an expression function declared within a nested package, when
1877 some type in the profile depends on a private type declared in
1878 an enclosing package.
1880 2017-09-08 Bob Duff <duff@adacore.com>
1882 * gnat1drv.adb (Gnat1drv): Do not set the Force_ALI_Tree_File flag in
1883 the subunit case. It's still OK to set it in the "missing subunits"
1884 case, because that won't cause the obsolete .ali files that cause
1885 confusion.

1919 do not override the normalized position and first bit
1920 if they have already been set. Move fallback code
1921 for the packed case to the case where it belongs.
1922 * sem_ch13.adb (Adjust_Record_For_Reverse_Bit_Order):
1923 Also adjust the normalized position of components.
1924 (Adjust_Record_For_Reverse_Bit_Order_Ada_95): Likewise.

1928 * exp_disp.adb (Make_DT, Set_All_DT_Position): Handle properly
1929 the placement of a primitive operation O that renames an operation
1930 R declared in an inner package, and which is thus not a primitive
1931 of the dispatching type of O. In this case O is a new primitive
1932 and does not inherit its dispatch table position from R (which

1952 * sem_ch12.adb (Check_Generic_Parent): New procedure within
1953 Analyze_Associations, to handle actual packages that depend on
1954 previous instances. If a package IAP that is an instantiation is
1955 used as an actual in a subsequent instantiation SI in the same
1956 scope, and IAP has a body, IAP must be frozen before SI. If
1957 the generic parent of IAP is itself declared in a previous
1958 instantiation in the same scope, that instantiation must also
1959 be frozen before SI.

2180 * exp_ch3.ads (Init_Secondary_Tags): Adding new formal
2181 (Init_Tags_List) to facilitate generating separate code in the

2183 the elaboration of dispatch tables.
2184 * exp_ch3.adb (Build_Init_Procedure): Improve the code
2185 generated in the IP routines by means of keeping separate
2186 the initialization of the object components from the
2187 initialization of its dispatch tables. (Init_Secondary_Tags):

2189 Ada.Tags.Set_Dynamic_Offset_To_Top since it has a new formal;

2191 because the type of one of its formals has been changed.
2192 * a-tags.ads, a-tags.adb (Register_Interface_Offset): Profile
2193 modified. Instead of receiving a pointer to an object this
2194 routine receives now a primary tag.
2195 (Set_Dyanic_Offset_To_Top): Profile modified. This routine receives an
2196 additional formal: the tag of the primary dispatch table.
2197 * exp_disp.ads (Elab_Flag_Needed): New subprogram.
2198 * exp_disp.adb (Elab_Flag_Needed): New subprogram.

2230 is now consulted not only for abstract states and variables,
2231 but for all kinds of items.

2239 * ghost.adb (Check_Ghost_Context): Do not err on ghost code inside

2252 derived recor type, copy the dikensions if any of each component
2253 of the parent record to the corresponding component declarations
2254 of the derived record. These expressions are used among other
2255 things as default values in aggregates with box associations.

2304 remove qualifications and type conversions. Fix various bugs
2305 where only a single level of qualification or conversion was
2306 removed, so e.g. "T1'(T2'(X))" would incorrectly return "T2'(X)"
2307 instead of "X".
2308 * checks.adb, exp_util.ads, exp_util.adb, sem_res.adb: Misc related
2309 cleanup.
2311 2017-09-07 Ed Schonberg <schonberg@adacore.com>

2314 do not create actual subtypes that may generate further predicate
2315 functions.
2316 * sem_ch13.adb (Build_Predicate_Functions): Indicate that entity
2317 of body is a predicate function as well.
2318 (Resolve_Aspect_Expressions, Resolve_Name): For a component
2319 association, only the expression needs resolution, not the name.
2320 (Resolve_Aspect_Expressions, case Predicates): Construct and
2321 analyze the predicate function declaration in the scope of the
2322 type, before making the type and its discriminants visible.

2363 2017-09-06 Bob Duff <duff@adacore.com>
2365 * binde.adb (Find_Elab_Order): Do not run Elab_Old unless
2366 requested. Previously, the -do switch meant "run Elab_New and
2367 Elab_Old and use the order chosen by Elab_Old, possibly with
2368 debugging printouts comparing the two orders." Now it means
2369 "do not run Elab_New." This is of use if there are bugs that
2370 cause Elab_New to crash.
2371 (Elab_Position, Num_Chosen): Change type to Nat, to avoid various
2372 type conversions.
2373 * ali.ads (Elab_Position): Change type to Nat, to avoid various

2388 <Sized_Component_Total_Round_RM_Size>: New local variable to
2389 accumulate the rounded RM_Size of components. Update it for
2390 every component whose RM_Size is statically known. Add missing
2391 guard to check that bit packing is really required before issuing
2392 the error about packing. Swap condition for clarity's sake.

2414 2017-09-06 Ed Schonberg <schonberg@adacore.com>
2416 * sem_ch5.adb (Analyze_Assigment): If the left-hand side is an
2417 entity of a mutable type and the right-hand side is a conditional
2418 expression, resolve the alternatives of the conditional using
2419 the base type of the target entity, because the alternatives

2425 * checks.adb (Apply_Predicate_Check): If the expression is an
2426 aggregate that is the RHS of an assignment, apply the check to
2427 the LHS after the assignment, rather than to the aggregate. This
2428 is more efficient than creating a temporary for the aggregate,
2429 and prevents back-end crashes when the aggregate includes a
2430 dynamic "others' association.

2455 style messages, which should not be called in that case because
2456 Warning_Msg_Char is not set.
2458 2017-09-06 Justin Squirek <squirek@adacore.com>
2460 * sem_prag.adb (Check_VFA_Conflicts): Created
2461 to group all Volatile_Full_Access checks relating to other
2462 representation pragmas (Mark_Component_Or_Object): Created
2463 to centeralize the flagging of attributes for the record type
2464 component case, a pragma applied individually to a component, and
2465 the object case.
2466 (Process_Atomic_Independent_Shared_Volatile):
2467 Add propagation of certain pragmas to record components and move
2468 evaluation of VFA checks
2470 2017-09-06 Ed Schonberg <schonberg@adacore.com>
2472 * sem_prag.adb (Check_Postcondition_Use_In_Inlined_Subprogram):

2483 * sem_ch12.adb (Copy_Generic_Node): When we copy a node
2484 that is a proper body corresponding to a stub, we defer the
2485 adjustment of the sloc until after the correct adjustment has
2486 been computed. Otherwise, Adjust_Instantiation_Sloc will ignore
2487 the adjustment, because it will be outside the range in (the old,
2488 incorrect) S_Adjustment.
2489 * inline.adb: Use named notation for readability and uniformity.
2490 * sinput-l.adb: Minor improvements to debugging output printed
2491 for Debug_Flag_L.

2501 * sem_eval.adb (Compile_Time_Known_Value_Or_Aggr): Adding a
2502 case when Op is of kind N_Qualified_Expression. In this case,
2503 the function is called recursively on the subexpression like in
2504 other cases.
2505 * make.adb: Minor reformatting
2507 2017-09-06 Justin Squirek <squirek@adacore.com>
2509 * einfo.adb (Set_Linker_Section_Pragma): Modify
2510 Set_Linker_Section_Pragma to be consistant with the "getter"
2511 Linker_Section_Pragma.
2512 * exp_ch5.adb (Expand_Formal_Container_Loop): Add proper error
2513 checking for container loops so that the index cursor is not
2514 directly changable by the user with the use of E_Loop_Parameter.
2515 * sem_ch5.adb (Analyze_Block_Statement): Revert previous change.

2542 from source before checking source references.
2543 * sem_warn.adb (Check_References): Add check for internal block
2544 before recursing.
2546 2017-09-06 Vincent Celier <celier@adacore.com>

2559 * sem_ch12.adb (Analyze_Associations, case of Formal_Package):
2560 Generate a freeze node for the actual of a formal package, if
2561 the actual is declared in the same unit and has a corresponding
2562 body, to prevent the current instance from being frozen before
2563 the actual is.
2565 2017-09-06 Eric Botcazou <ebotcazou@adacore.com>
2567 * sem_ch7.adb (Entity_Table_Size): Change to nearest prime number.

2593 * sysdep.c (__gnat_has_cap_sys_nice): If HAVE_CAPABILITY is defined,
2594 we include the proper header. Otherwise, we just declare the necessary
2595 things from the capabilities library. This is so we can build on
2596 machines without that library, while still enabling that library.
2597 At run time, we're using weak symbols, so __gnat_has_cap_sys_nice will
2598 simply return 0 if the library is not present, or not included
2599 in the link.

2611 2017-09-06 Pierre-Marie de Rodat <derodat@adacore.com>
2613 * par_sco.adb (Extend_Statement_Sequence): When the accept statement
2614 has no parameter specification and no entry index, use the entry name
2615 as the end of the generated SCO statement.
2617 2017-09-06 Steve Baird <baird@adacore.com>
2619 * exp_util.adb (Side_Effect_Free): For CodePeer (only) treat
2620 uses of 'Image and related attributes as having side effects in
2621 order to avoid replicating such uses.
2622 * pprint.ads (Expression_Image) Add new generic formal flag
2623 Hide_Temp_Derefs. The flag defaults to False; CodePeer will
2624 (eventually) override the default.
2625 * pprint.adb (Expression_Image) If the new flag is set, then
2626 suppress the ".all" suffix when displaying a dereference whose
2627 prefix is a use of a value-capturing compiler temp of the sort
2628 generated by Expr_Util.Remove_Side_Effects .
2629 * exp_attr.adb, g-catiio.adb, inline.adb, sem_attr.adb, sem_ch13.adb,

2642 * sem_util.adb, sem_util.ads (Within_Protected_Type): Renaming
2643 with slight modification from Is_Subp_Or_Entry_Inside_Protected,
2644 so that applies to any entity.
2646 2017-09-06 Yannick Moy <moy@adacore.com>
2648 * sem_ch3.adb (Derived_Type_Declaration): Use
2649 Incomplete_Or_Partial_View rather than local Find_Partial_View.

2653 * g-catiio.ads, g-catiio.adb (Value): Extended to parse an UTC time
2654 following ISO-8861.

2658 * sem_dim.adb (Analyze_Dimension): In an instance, a type
2659 conversion takes its dimensions from the expression, not from
2660 the context type.
2661 (Dimensions_Of_Operand): Ditto.
2663 2017-09-06 Ed Schonberg <schonberg@adacore.com>
2665 * exp_ch6.adb (Expand_Call_Helper): Do not optimize calls to

2677 * sem_res.adb (Resolve_Arithmentic_Op): If both operands are
2678 Universal_Real and the context is a floating-point type, resolve
2679 both operands to the target type.
2681 2017-09-06 Hristian Kirtchev <kirtchev@adacore.com>

2688 * freeze.adb (Check_Inherited_Conditions): Rewriting
2689 of inherited preconditions and postconditions should only occur
2690 in GNATprove mode, that is, when GNATprove_Mode is True, not to

2710 (Subprogram_Table): New instantiation of GNAT.Htable.Simple_HTable.
2711 (Is_Subprogram_Ref): Rename into...
2712 (Scan_Subprogram_Ref): ...this. Record references to subprograms in
2713 the table instead of bailing out on them. Scan the value of constants
2714 if it is not known at compile time.
2715 (Contains_Subprograms_Refs): Rename into...
2716 (Scan_Subprogram_Refs): ...this.
2717 (Has_Referencer): Scan the body of all inlined subprograms. Reset the

2774 capability.
2776 2017-09-06 Bob Duff <duff@adacore.com>
2778 * a-comlin.ads, a-comlin.adb (Argument): Move the constraint

2832 Ada.Command_Line, which would damage the bootstrap process now
2833 that Ada.Command_Line contains modern Ada (the raise expression).
2834 * gnatbind.adb: Avoid dependence on
2835 Ada.Command_Line. Depend on System.Response_File instead
2836 of Ada.Command_Line.Response_File. Change one call to

2838 to Ada.Command_Line.Argument_Count to use Arg_Count.
2839 * gcc-interface/Make-lang.in, Makefile.rtl: Take note of the new files.
2841 2017-09-06 Bob Duff <duff@adacore.com>
2843 * frontend.adb (Frontend): Skip -gnatec=gnat.adc

2853 2017-09-06 Yannick Moy <moy@adacore.com>
2855 * sem_warn.adb (Warn_On_Suspicious_Index): Improve warning when the

2905 procedure is No_Return.
2906 * sem_ch8.adb (Analyze_Subprogram_Renaming): Implement legality
2907 rule in 6.5.1 (7/2): if a renaming is a completion of a subprogram
2908 with No_Return, the renamed entity must be No_Return as well.
2910 2017-09-06 Hristian Kirtchev <kirtchev@adacore.com>
2912 * exp_ch5.adb, freeze.adb, exp_ch4.adb, exp_ch6.adb, lib-xref.adb:

2929 * freeze.adb (Freeze_Entity): Do not generate a freeze
2930 node for a generic unit, even if it includes delayed aspect
2931 specifications. Freeze nodes for generic entities must never
2932 appear in the tree that reaches the back-end of the compiler.

3926 constant declaration while the other is an input parameter to
3927 the corresponding generated subprogram.
3929 2017-05-02 Justin Squirek <squirek@adacore.com>
3931 * sem_ch3.adb (Check_For_Null_Excluding_Components): Created for
3932 recursivly searching composite-types for null-excluding access
3933 types and verifying them.

3936 of non-initialized objects.
3937 * checks.adb, checks.ads (Null_Exclusion_Static_Checks): Added
3938 a parameter for a composite-type's component and an extra case
3939 for printing component information.
3941 2017-05-02 Yannick Moy <moy@adacore.com>
3943 * sem_ch10.adb (Analyze_Subunit): Take
3944 configuration pragma into account when restoring appropriate
3945 pragma for analysis of subunit.
3947 2017-05-02 Justin Squirek <squirek@adacore.com>
3949 * s-tasren.adb, s-tasini.adb, s-taprop-linux.adb,
3950 s-mudido-affinity.adb,, a-exetim-posix.adb, a-direio.adb,
3951 g-socket.adb, s-taenca.adb, s-fileio.adb: Remove unused use-type
3952 clauses from the runtime.
3954 2017-05-02 Eric Botcazou <ebotcazou@adacore.com>
3956 * freeze.adb (Check_Component_Storage_Order): Do not treat bit-packed
3957 array components specially.
3959 2017-05-02 Ed Schonberg <schonberg@adacore.com>
3961 * sem_ch8.adb (Premature_Usage): If the premature usage of
3962 an entity is as the expression in its own object decaration,
3963 rewrite the reference as Any_Id to prevent cascaded errors or
3964 compiler loops when such an entity is used in an address clause.
3966 2017-05-01 Eric Botcazou <ebotcazou@adacore.com>
3968 * gcc-interface/decl.c (components_to_record): Add missing guard.
3970 2017-05-01 Eric Botcazou <ebotcazou@adacore.com>
3972 * gcc-interface/decl.c (components_to_record): Add more comments.
3973 Put back pending fields onto the regular list if the misalignment
3974 happens to cancel itself.
3976 2017-04-28 Ed Schonberg <schonberg@adacore.com>
3978 * sem_ch4.adb (Complete_Object_Operation): When rewriting the
3979 controlling actual in a prefixed call, preserve the original node
3980 information if the prefix itself has been rewritten, for ASIS use.
3982 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
3984 * exp_ch6.adb (Insert_Post_Call_Actions):
3985 Code clean up. Insert the post-call actions after an enclosing
3986 procedure call when N denotes a function call and appears as an
3987 actual parameter in the procedure call.
3989 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
3991 * freeze.adb (Check_Component_Storage_Order): If there is a clause
3992 for the component, also reject the attribute if the component
3993 doesn't end on a byte boundary and its scalar storage order is
3994 different from that of the enclosing record type.
3996 2017-04-28 Javier Miranda <miranda@adacore.com>
3998 * atree.ads (Info_Messages): Removed.
3999 (Warning_Info_Messages): New counter.
4000 (Report_Info_Messages): New counter.
4001 * err_vars.ads Update documentation.
4002 * errout.adb (Delete_Warning_And_Continuations): Update
4003 Info_Message occurrences.

4012 (Initialize): Update Info_Message occurrences.
4013 * erroutc.adb (Delete_Msg): Update Info_Message occurrences.
4014 (Compilation_Errors): Update Info_Message_Occurences.
4016 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
4018 * exp_ch3.adb (Build_Init_Statements): Likewise on Nam.
4019 * freeze.adb (Check_Component_Storage_Order): And on Comp_Byte_Aligned.
4020 * sem_aggr.adb (Resolve_Record_Aggregate): Initialize Box_Node.
4021 * sem_attr.adb (Loop_Entry): Initialize Encl_Loop.
4022 * sem_ch12.adb (Build_Operator_Wrapper): Add pragma Warnings on Expr.
4023 * sem_ch13.adb (Validate_Address_Clauses): Initialize Y_Alignment and
4024 Y_Size.

4026 * sem_prag.adb (Analyze_Pragma): Add pragma Warnings on Str.
4028 2017-04-28 Bob Duff <duff@adacore.com>
4030 * sem_util.ads, sem_util.adb (Might_Raise): New function
4031 that replaces Is_Exception_Safe, but has the opposite
4032 sense. Is_Exception_Safe was missing various cases -- calls inside
4033 a pragma Debug, calls inside an 'if' or assignment statement,
4034 etc. Might_Raise now walks the entire subtree looking for things
4035 that can raise.
4036 * exp_ch9.adb (Is_Exception_Safe): Remove.
4037 (Build_Protected_Subprogram_Body): Replace call to
4038 Is_Exception_Safe with "not Might_Raise". Misc cleanup (use
4039 constants where possible).
4040 * exp_ch7.adb: Rename Is_Protected_Body -->
4041 Is_Protected_Subp_Body. A protected_body is something different
4042 in the grammar.
4044 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
4046 * inline.adb (Expand_Inlined_Call): Initialize Targ1 variable.

4057 (Analyze_Iterator_Specification): Initialize Bas variable.
4058 * sem_ch9.adb (Allows_Lock_Free_Implementation): Initialize
4059 Error_Count (Satisfies_Lock_Free_Requirements): Likewise.
4060 (Analyze_Accept_Statement): Initialize Task_Nam.
4062 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
4064 * checks.adb (Install_Primitive_Elaboration_Check):
4065 Do not generate an elaboration check if all checks have been
4066 suppressed.
4068 2017-04-28 Ed Schonberg <schonberg@adacore.com>
4070 * sem_ch13.adb (Analyze_Aspect_Specifications, case
4071 Interrupt_Handler and Attach_Handler): Generate reference
4072 to protected operation to prevent spurious warnings about
4073 unreferenced entities. Previous scheme failed with style checks
4074 enabled.
4076 2017-04-28 Ed Schonberg <schonberg@adacore.com>
4078 * sem_prag.adb (Relocate_Pragmas_To_Body): A pragma Warnings
4079 that follows an expression function must not be relocated to
4080 the generated body, because it applies to the code that follows.
4082 2017-04-28 Gary Dismukes <dismukes@adacore.com>
4084 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): Test
4085 Relaxed_RM_Semantics to avoid having CodePeer issue errors on
4086 code that might violate the more stringent checking for 'Access
4087 introduced in Ada 2005.
4089 2017-04-28 Arnaud Charlet <charlet@adacore.com>
4091 * a-cforse.adb: minor style fix in comment.
4093 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
4095 * exp_ch9.adb (Build_Lock_Free_Unprotected_Subprogram_Body): Also
4096 initialize Block_Decls variable.
4097 (Expand_Entry_Barrier): Add pragma Warnings on Func_Body variable.
4098 (Build_Dispatching_Requeue): Add pragma Warnings on Op variable.
4099 * exp_disp.adb (Expand_Interface_Actuals): Initialize
4100 Formal_DDT and Actual_DDT variables.
4101 (Expand_Interface_Thunk): Initialize Iface_Formal.
4102 (Make_DT): Initialize Size_Comp.
4103 (Make_Select_Specific_Data_Table): Initialize Decls.
4104 * exp_dist.adb (Add_RACW_Primitive_Declarations_And_Bodies):
4105 Also initialize more RPC_Receiver_* variables.
4106 (Build_To_Any_Function): Initialize Cstr_Formal.
4107 * exp_prag.adb (Expand_Pragma_Contract_Cases): Initialize Msg_Str.
4109 2017-04-28 Ed Schonberg <schonberg@adacore.com>
4111 * sem_ch6.adb (Freeze_Type_Refs): For an interface conversion
4112 node between access types, freeze the designated type as well,
4113 so that dispatch table pointers are created in the proper scope,
4114 and not in the constructed body of the expression function.
4116 2017-04-28 Bob Duff <duff@adacore.com>
4118 * alloc.ads (Nodes_Initial): Go back to previous value. The large
4119 value makes large compilations faster, but small compilations slower.
4121 2017-04-28 Arnaud Charlet <charlet@adacore.com>
4123 * sem_util.adb: minor typos in Is_Child_Or_Sibling.
4125 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
4127 * erroutc.adb (Compilation_Errors): Do not consider info messages
4128 as suitable warnings when warnings must be treated as errors.
4129 * sem_ch7.adb (Analyze_Package_Specification): Do not consider
4130 internally-generated packages when outputting completion
4131 information.
4132 * errout.adb (Output_Messages): Do not consider info messages as
4133 suitable warnings when warnings must be treated as errors.
4134 * errutil.adb (Finalize): Do not consider info messages as
4135 suitable warnings when warnings must be treated as errors.
4137 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
4139 * warnsw.ads: Minor fix for incorrect wording in comment.
4141 2017-04-28 Ed Schonberg <schonberg@adacore.com>
4143 * sem_res.adb (In_Instance_Code): New predicate in
4144 Valid_Conversion, to determine whether a type conversion appears
4145 as (or within) an actual for a formal object. Type conversions
4146 in instances are not rechecked in Valid_Conversion because
4147 visibility changes between generic location andi instance may
4148 lead to spurious errors, but conversions within an actual must be
4149 fully checked, and they are not fully resolved when pre-analyzing
4150 the actuals.
4152 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
4154 * exp_ch6.adb (Expand_N_Extended_Return_Statement): Use
4155 New_Copy_Tree instead of Relocate_Node as any subsequent copies
4156 of the relocated node will have mangled Parent pointers.
4157 * sem_util.adb (Build_NCT_Hash_Tables): Reset both hash
4158 tables used in conjunction with entity and itype replication.
4159 (Visit_Entity): Rewrite the restriction on which entities
4160 require duplication. The restriction now includes all types.
4162 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
4164 * a-cofuse.ads, a-cfdlli.ads, a-cfhase.adb, a-cfhase.ads, a-cfinve.adb,
4165 a-cfinve.ads, a-cforma.adb, a-cforma.ads, a-cofuma.adb, a-cofuma.ads,
4166 a-cfhama.adb, a-cfhama.ads, a-cforse.adb: Minor reformatting and code
4167 cleanups.
4169 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
4171 * exp_util.adb, g-dyntab.adb, par-ch4.adb, sem_util.adb, sem_attr.adb,
4172 gnat1drv.adb, exp_disp.adb, namet.adb, alloc.ads: Minor reformatting.
4174 2017-04-28 Gary Dismukes <dismukes@adacore.com>
4176 * exp_util.adb: Minor reformatting.
4178 2017-04-28 Ed Schonberg <schonberg@adacore.com>
4180 * sem_ch4.adb: Fix copy/pasto.
4182 2017-04-27 Tristan Gingold <gingold@adacore.com>
4184 * gcc-interface/Make-lang.in: Define EH_MECHANISM while building
4185 raise-gcc.c. Fix include search path for raise-gcc.c
4187 2017-04-27 Eric Botcazou <ebotcazou@adacore.com>
4189 * fe.h (Warn_On_Questionable_Layout): Declare.
4190 * warnsw.ads (Warn_On_Record_Holes): Move down.
4191 (Warn_On_Questionable_Layout): New boolean variable.
4192 (Warning_Record): Add Warn_On_Questionable_Layout field.
4193 * warnsw.adb (All_Warnings): Set Warn_On_Questionable_Layout.
4194 (Restore_Warnings): Likewise.
4195 (Save_Warnings): Likewise.
4196 (Set_Dot_Warning_Switch): Handle 'q' and 'Q' letters.
4197 * gcc-interface/decl.c (gnat_to_gnu_entity): Adjust call to
4198 components_to_record.
4199 (gnu_field_to_gnat): New function.
4200 (warn_on_field_placement): Likewise.
4201 (components_to_record): Add GNAT_RECORD_TYPE and remove REORDER
4202 parameters. Rename local variables and adjust recursive call.
4203 Rework final scan of the field list and implement warnings on the
4204 problematic placement of specific sorts of fields.
4206 2017-04-27 Bob Duff <duff@adacore.com>
4208 * errout.adb, exp_aggr.adb, exp_attr.adb, exp_code.adb, fname.adb,
4209 * fname.ads, freeze.adb, inline.adb, lib.adb, lib.ads, lib-list.adb,
4210 * lib-load.adb, lib-writ.adb, par.adb, restrict.adb, rtsfind.adb,
4211 * sem.adb, sem_cat.adb, sem_ch10.adb, sem_ch12.adb, sem_ch3.adb,
4212 * sem_ch4.adb, sem_ch6.adb, sem_ch8.adb, sem_ch9.adb, sem_elab.adb,
4213 * sem_intr.adb, sem_res.adb, sem_util.adb, sem_warn.adb, sprint.adb:
4214 For efficiency, cache results of Is_Internal_File_Name and
4215 Is_Predefined_File_Name in the Units table. This avoids a lot
4216 of repeated text processing.
4218 2017-04-27 Emmanuel Briot <briot@adacore.com>
4220 * g-comlin.adb (Sort_Sections): remove useless test.
4222 2017-04-27 Claire Dross <dross@adacore.com>
4224 * a-cfhase.adb, a-cfhase.ads (=): Generic parameter removed to
4225 allow the use of regular equality over elements in contracts.
4226 (Formal_Model): Ghost package containing model functions that are
4227 used in subprogram contracts.
4228 (Current_To_Last): Removed, model functions should be used instead.
4229 (First_To_Previous): Removed, model functions should be used instead.
4230 (Strict_Equal): Removed, model functions should be used instead.
4231 (No_Overlap): Removed, model functions should be used instead.
4232 (Equivalent_Keys): Functions over cursors are removed. They were
4233 awkward with explicit container parameters.
4234 * a-cforse.adb, a-cforse.ads (=): Generic parameter removed to
4235 allow the use of regular equality over elements in contracts.
4236 (Formal_Model): Ghost package containing model functions that
4237 are used in subprogram contracts.
4238 (Current_To_Last): Removed, model functions should be used instead.
4239 (First_To_Previous): Removed, model functions should be used instead.
4240 (Strict_Equal): Removed, model functions should be used instead.
4241 (No_Overlap): Removed, model functions should be used instead.
4243 2017-04-27 Yannick Moy <moy@adacore.com>
4245 * gnat1drv.adb: Code cleanup.
4247 2017-04-27 Ed Schonberg <schonberg@adacore.com>
4249 * exp_util.adb (Replace_Entity): The prefix of a 'Result
4250 attribute reference in a post- condition is the subprogram to
4251 which the condition applies. If the condition is inherited
4252 by a type extension, the prefix becomes a reference to the
4253 inherited operation, but there is no need to create a wrapper
4254 for this operation, because 'Result is expanded independently
4255 when elaborating the postconditions.
4257 2017-04-27 Bob Duff <duff@adacore.com>
4259 * sinput.adb: Minor code cleanup.
4260 * namet.adb (Append): Create faster versions of
4261 Append(String) and Append(Name_Id) by using slice assignment
4262 instead of loops.
4263 * sem_util.adb (In_Instance): Speed this up by removing
4264 unnecessary tests; Is_Generic_Instance is defined for all
4265 entities.
4266 * sem_util.ads, sem_util.adb (In_Parameter_Specification):
4267 Remove unused function.
4268 * alloc.ads (Nodes_Initial): Use a much larger value, because
4269 the compiler was spending a lot of time copying the nodes table
4270 when it grows. This number was chosen in 1996, so is rather out
4271 of date with current memory sizes. Anyway, it's virtual memory.
4272 Get rid of Orig_Nodes_...; use Node_... instead.
4273 * atree.adb (Lock): Do not release the Nodes tables; it's a
4274 waste of time.
4275 Orig_Nodes_ ==> Nodes_
4276 * nlists.adb: Orig_Nodes_ ==> Nodes_
4277 * g-table.adb: Remove unused "with" clause.
4278 * g-table.ads, table.ads: Remove Big_Table_Type, which should
4279 not be used by clients.
4280 * g-dyntab.adb (Last_Allocated): New function
4281 to encapsulate T.P.Last_Allocated, which I'm thinking of changing.
4283 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
4285 * sem_eval.adb (Subtypes_Statically_Compatible): Remove duplicated
4286 check.
4287 (Subtypes_Statically_Match): Remove duplicate check.
4288 * sem_prag.adb (Check_Arg_Is_External_Name): Remove duplicate check.
4290 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
4292 * exp_aggr.adb (Replace_Type): Remove the special processing
4293 for selected components.
4294 * exp_attr.adb (Expand_N_Attribute_Reference): Merge the
4295 processing for attributes Fixed_Value and Integer_Value.
4296 * exp_util.adb (Side_Effect_Free): Merge the processing for
4297 qualified expressions, type conversions, and unchecked type
4298 conversions.
4299 * g-comlin.adb (Is_In_Config): Merge the processing for No_Space
4300 and Optional.
4301 * par-ch3.adb (P_Declarative_Items): Merge the processing for
4302 tokens function, not, overriding, and procedure.
4303 * sem_ch6.adb (Fully_Conformant_Expressions): Merge the processing
4304 for qualified expressions, type conversions, and unchecked
4305 type conversions.
4306 * sem_util.adb (Compile_Time_Constraint_Error): Merge the
4307 processing for Ada 83 and instances.
4308 (Object_Access_Level): Merge the processing for indexed components
4309 and selected components.
4310 * uname.adb (Add_Node_Name): Merge the processing for stubs.
4312 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
4314 * checks.adb (Install_Primitive_Elaboration_Check):
4315 Do not generate the check when restriction No_Elaboration_Code
4316 is in effect.
4318 2017-04-27 Ed Schonberg <schonberg@adacore.com>
4320 * exp_disp.adb (Build_Class_Wide_Check): New subsidiary
4321 of Expand_Dispatching_Call. If the denoted subprogram has a
4322 class-wide precondition, this is the only precondition that
4323 applies to the call, rather that the class-wide preconditions
4324 that may apply to the body that is executed. (This is specified
4325 in AI12-0195).
4327 2017-04-27 Yannick Moy <moy@adacore.com>
4329 * gnat1drv.adb (Adjust_Global_Switches): Issue
4330 a warning in GNATprove mode if the runtime library does not
4331 support IEEE-754 floats.
4333 2017-04-27 Ed Schonberg <schonberg@adacore.com>
4335 * sem_prag.adb (Inherit_Class_Wide_Pre): If the parent operation
4336 is itself inherited it does not carry any contract information,
4337 so examine its parent operation which is its Alias.
4339 2017-04-27 Ed Schonberg <schonberg@adacore.com>
4341 * sem_attr.adb (Analyze_Attribute, case 'Image): In Ada2012 the
4342 prefix can be an object reference in which case Obj'Image (X)
4343 can only be interpreted as an indexing of the parameterless
4344 version of the attribute.
4345 * par-ch4.adb (P_Name): An attribute reference can be the prefix of
4346 an indexing or a slice operation if the attribute does not require
4347 parameters. In Ada2012 'Image also belongs in this category,
4348 and A'Image (lo .. hi) is legal and must be parsed as a slice.
4350 2017-04-27 Yannick Moy <moy@adacore.com>
4352 * exp_ch4.adb: Minor reformatting.
4353 * gnat1drv.adb (Adjust_Global_Switches): When in GNATprove mode,
4354 disable the CodePeer and C generation modes. Similar to the
4355 opposite actions done in CodePeer mode.
4357 2017-04-27 Yannick Moy <moy@adacore.com>
4359 * sem_res.adb: Remove duplicate code.
4360 * sem_attr.adb: Delete duplicate code.
4362 2017-04-27 Bob Duff <duff@adacore.com>
4364 * g-dyntab.adb: Reduce the amount of copying in
4365 Release. No need to copy items past Last.
4367 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>

4370 (Install_Primitive_Elaboration_Check): New routine.
4371 * checks.ads (Install_Primitive_Elaboration_Check): New routine.
4372 * exp_attr.adb (Expand_N_Attribute_Reference): Clean up the
4373 processing of 'Elaborated.
4374 * exp_ch6.adb (Expand_N_Subprogram_Body): Install a primitive
4375 elaboration check.
4377 2017-04-27 Bob Duff <duff@adacore.com>
4379 * g-dyntab.ads, g-dyntab.adb, g-table.ads: Remove incorrect assertion.
4380 If the table grows and then shrinks back to empty, we won't necessarily
4381 point back to the empty array. Code cleanups.
4382 * sinput.ads: Add 'Base to Size clause to match the declared
4383 component subtypes.
4385 2017-04-27 Claire Dross <dross@adacore.com>
4387 * a-cforma.adb, a-cforma.ads (=): Generic parameter removed to
4388 allow the use of regular equality over elements in contracts.
4389 (Formal_Model): Ghost package containing model functions that
4390 are used in subprogram contracts.
4391 (Current_To_Last): Removed, model functions should be used instead.
4392 (First_To_Previous): Removed, model functions should be used instead.
4393 (Strict_Equal): Removed, model functions should be used instead.
4394 (No_Overlap): Removed, model functions should be used instead.
4395 * a-cofuma.adb, a-cofuma.ads (Enable_Handling_Of_Equivalence)
4396 Boolean generic parameter to disable contracts for equivalence

4885 file.
4886 (__gnat_Unwind_ForcedUnwind): Adjust prototype.
4887 (db): Constify msg_format.
4888 (get_call_site_action_for): Don't use void arithmetic.
4889 * system.ads (Frontend_Exceptions): Set to False.
4890 (ZCX_By_Default): Set to True.
4891 (GCC_ZC_Support): Set to True.
4892 * gcc-interface/Makefile.in: No more variants for a-exexpr.adb and
4893 a-except.ad[sb].
4894 * gcc-interface/Make-lang.in: Add support for backend zcx exceptions
4895 in gnat1 and gnatbind.
4896 * gnat1, gnatbind: link with raise-gcc.o, a-exctra.o, s-addima.o,
4897 s-excmac.o, s-imgint.o, s-traceb.o, s-trasym.o, s-wchstw.o
4898 * s-excmac.ads, s-excmac.adb: Copy of variants.
4899 * a-except.o: Adjust preequisites.
4900 Add handling of s-excmac-arm.adb and s-excmac-gcc.adb.
4902 2017-04-27 Claire Dross <dross@adacore.com>
4904 * a-cfdlli.adb, a-cfdlli.ads (Formal_Model): Adapt to
4905 modifications in functional containers.
4906 * a-cofuba.ads, a-cofuma.ads, a-cofuse.ads, a-cofuve.ads Reformat
4907 to improve readablity. Subprograms are separated between basic
4908 operations, constructors and properties. Universally quantified
4909 formulas in contracts are factorized in independant functions
4910 with a name and a comment. Names of parameters are improved.
4912 2017-04-27 Gary Dismukes <dismukes@adacore.com>
4914 * exp_spark.adb, sem_elab.adb: Minor reformatting and typo fix.
4916 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
4918 * sem_res.adb (Resolve_Type_Conversion): Do not
4919 install a predicate check here since this is already done during
4920 the expansion phase. Verify whether the operand satisfies the
4921 static predicate (if any) of the target type.
4922 * sem_ch3.adb (Analyze_Object_Declaration): Do
4923 not install a predicate check if the object is initialized by
4924 means of a type conversion because the conversion is subjected
4925 to the same check.
4927 2017-04-27 Tristan Gingold <gingold@adacore.com>
4929 * a-except.ads, a-except.adb, a-exexpr.adb: Removed (will be
4930 replaced by their variants).
4932 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
4934 * exp_prag.adb, a-cofuse.adb, a-cofuse.ads, einfo.adb, sem_prag.adb,
4935 cstand.adb, par-prag.adb, a-cofuve.adb, a-cofuve.ads, a-cofuma.adb,
4936 a-cofuma.ads, a-cofuba.adb, a-cofuba.ads: Minor reformatting.
4938 2017-04-27 Tristan Gingold <gingold@adacore.com>
4940 * s-excmac-gcc.ads, s-excmac-gcc.adb,
4941 s-excmac-arm.ads, s-excmac-arm.adb (New_Occurrence): Rewrite it in
4942 Ada95.
4944 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
4946 * exp_ch7.adb (Establish_Transient_Scope): Rewrite
4947 the loop which detects potential enclosing transient scopes. The
4948 loop now terminates much earlier as transient scopes are bounded
4949 by packages and subprograms.
4951 2017-04-27 Claire Dross <dross@adacore.com>
4953 * a-cfdlli.adb, a-cfdlli.ads (=): Generic parameter removed to
4954 allow the use of regular equality over elements in contracts.
4955 (Cursor): Type is now public so that it can be used in
4956 model functions.
4957 (Formal_Model): Ghost package containing
4958 model functions that are used in subprogram contracts.
4959 (Current_To_Last): Removed, model functions should be used
4960 instead.
4961 (First_To_Previous): Removed, model functions should
4962 be used instead.
4963 (Strict_Equal): Removed, model functions
4964 should be used instead.
4965 (Append): Default parameter value
4966 replaced by new wrapper to allow more precise contracts.
4967 (Insert): Default parameter value replaced by new wrapper to
4968 allow more precise contracts.
4969 (Delete): Default parameter
4970 value replaced by new wrapper to allow more precise contracts.
4971 (Prepend): Default parameter value replaced by new wrapper to
4972 allow more precise contracts.
4973 (Delete_First): Default parameter
4974 value replaced by new wrapper to allow more precise contracts.
4975 (Delete_Last): Default parameter value replaced by new wrapper
4976 to allow more precise contracts.
4978 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
4980 * exp_spark.adb (Expand_SPARK): Perform specialized expansion
4981 for object declarations.
4982 (Expand_SPARK_N_Object_Declaration): New routine.
4983 * sem_elab.adb (Check_A_Call): Include calls to the
4984 Default_Initial_Condition procedure of a type under the SPARK
4985 elaboration checks umbrella.
4987 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
4989 * sem.adb (Analyze): Diagnose an illegal iterated component
4990 association.
4991 * sem_util.ads, sem_util.adb
4992 (Diagnose_Iterated_Component_Association): New routine.
4994 2017-04-27 Bob Duff <duff@adacore.com>
4996 * adaint.c (__gnat_get_current_dir): Return 0 in length if
4997 getcwd fails.
4998 * a-direct.adb, g-dirope.adb, osint.adb, s-os_lib.adb: Raise
4999 exception if getcwd failed.
5001 2017-04-27 Yannick Moy <moy@adacore.com>
5003 * exp_dbug.adb, exp_dbug.ads (Get_External_Name): Prefix ghost
5004 entities with special prefix.
5006 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
5008 * debug.adb Change the documentation of switch -gnatd.s.
5009 * exp_ch7.adb (Make_Transient_Block): Transient blocks do not need
5010 to manage the secondary stack when an enclosing scope already
5011 performs this functionality (aka relaxed management). Switch
5012 -gnatd.s may be used to force strict management in which case
5013 the block will manage the secondary stack unconditionally. Add
5014 a guard to stop the traversal when encountering a package or a
5015 subprogram scope.
5017 2017-04-27 Ed Schonberg <schonberg@adacore.com>
5019 * sem_res.adb (Resolve_Call): Refine further the handling of
5020 limited views of return types in function calls. If the function
5021 that returns a limited view appears in the current unit,
5022 we do not replace its type by the non-limited view because
5023 this transformation is performed int the back-end. However,
5024 the type of the call itself must be the non-limited view, to
5025 prevent spurious resolution errors.
5027 2017-04-27 Ed Schonberg <schonberg@adacore.com>
5029 * einfo,ads, einfo.adb (Class_Wide_Preconds, Class_Wide_Postconds):
5030 Removed, proposed implementation using generics for class-wide
5031 preconditions proved impractical.
5032 (Class_Wide_Clone): New attribute of subprogram. Designates
5033 subprogram created for primitive operations with class-wide
5034 pre/postconditions that contain calls to other primitives. The
5035 clone holds the body of the original primitive, but the
5036 pre/postonditions do not apply to it. The original body is
5037 rewritten as a wrapper for a call to the clone.
5038 (Is_Class_Wide_Clone): New flag to identify a Class_Wide_Clone. If
5039 the flag is set, no code for the corresponding pre/postconditions
5040 is inserted into its body.
5042 2017-04-27 Bob Duff <duff@adacore.com>
5044 * exp_prag.adb, par-prag.adb, sem_ch13.adb: Ignore
5045 Scalar_Storage_Order if -gnatI is given.
5046 * sem_prag.adb (Analyze_Pragma): Ignore
5047 Default_Scalar_Storage_Order if -gnatI is given.
5049 2017-04-27 Claire Dross <dross@adacore.com>
5051 * a-cofuba.ads (Add): Take as an additional input parameter
5052 the position where the element should be inserted.
5053 (Remove): New function that removes an element from the container.

5055 * a-cofuse.ads (Add): Adapt to the new API of Base.Add.
5056 (Remove): New function that removes an element from a set.
5057 * a-cofuve.ads (Add): Adapt to the new API of Base.Add.
5058 (Remove): New function that removes an element from a sequence.
5059 (Insert): New function that adds anywhere in a sequence.
5061 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
5063 * checks.adb (Generate_Range_Check): Revert previous change.
5065 2017-04-27 Gary Dismukes <dismukes@adacore.com>
5067 * sem_util.adb: Minor reformatting/rewording.
5069 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
5071 * lib-xref.adb (Generate_Reference): The use
5072 of attribute 'Result is not considered a violation of pragma
5073 Unreferenced.
5075 2017-04-27 Justin Squirek <squirek@adacore.com>
5077 * cstand.adb (Create_Standard): Correctly set
5078 Directly_Designated_Type for Any_Access.
5079 * sem_type.adb (Covers): Minor grammar fixes.
5081 2017-04-27 Bob Duff <duff@adacore.com>
5083 * sem_attr.adb: Minor cleanup.
5085 2017-04-27 Claire Dross <dross@adacore.com>

5088 private child of Ada.Containers used to implement all functional
5089 containers.
5090 * a-cofuma.ads, a-cofuma.adb (Ada.Containers.Functional_Maps): New
5091 child of Ada.Containers. It provides functional indefinite unbounded
5092 maps which can be used as high level models for specification
5093 of data structures.
5094 * a-cofuse.ads, a-cofuse.adb (Ada.Containers.Functional_Sets): New
5095 child of Ada.Containers. It provides functional indefinite unbounded
5096 sets which can be used as high level models for specification
5097 of data structures.
5098 * a-cofuve.ads, a-cofuve.adb (Ada.Containers.Functional_Vectors): New
5099 child of Ada.Containers. It provides functional indefinite unbounded
5100 vectors which can be used as high level models for specification
5101 of data structures.
5102 * Makefile.rtl: Add new packages.
5103 * impunit.adb: Add new packages.
5105 2017-04-27 Gary Dismukes <dismukes@adacore.com>
5107 * sem_ch4.adb: Minor reformatting.
5109 2017-04-27 Ed Schonberg <schonberg@adacore.com>
5111 * sem_ch12.adb (Analyze_Associations): minor reformatting.
5112 (Check_Fixed_Point_Actual): Do not emit a warning on a fixed
5113 point type actual that has user-defined arithmetic primitives,
5114 when there is a previous actual for a formal package that defines
5115 a fixed-point type with the parent user-defined operator.
5117 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
5119 * checks.adb (Generate_Range_Check): Reinstate part of previous change.
5120 * sem_attr.adb (Resolve_Attribute): Generate a range check when
5121 the component type allows range checks.
5123 2017-04-27 Ed Schonberg <schonberg@adacore.com>
5125 * sem_aux.adb (Is_Generic_Formal): Use original node to locate
5126 corresponding declaration, because formal derived types are
5127 rewritten as private extensions.
5129 2017-04-27 Ed Schonberg <schonberg@adacore.com>
5131 * sem_dim.adb (Analyze_Dimension_Binary_Op): Do not check
5132 dimensions of operands if node has been analyzed already, because
5133 previous analysis and dimension checking will have removed the
5134 dimension information from the operands.
5136 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
5138 * debug.adb: Document the use of switch -gnatd.s.
5139 * einfo.ads Update the documentation on attribute
5140 Sec_Stack_Needed_For_Return and attribute Uses_Sec_Stack. Remove
5141 the uses of these attributes from certain entities.
5142 * exp_ch7.adb (Make_Transient_Block): Reimplement the circuitry
5143 which determines whether the block should continue to manage
5144 the secondary stack.
5145 (Manages_Sec_Stack): New routine.
5147 2017-04-27 Bob Duff <duff@adacore.com>

5153 * sinfo.ads: Update the section on Ghost mode. Add
5154 a section on SPARK mode. Update the placement of section on
5155 expression functions.
5157 2017-04-27 Bob Duff <duff@adacore.com>
5159 * sinput.adb (Get_Source_File_Index): Don't
5160 assert that S is in the right range in the case where this is
5161 a .dg file under construction.
5163 2017-04-27 Yannick Moy <moy@adacore.com>
5165 * sem_util.adb (Check_Result_And_Post_State):
5166 Handle more precisely each conjunct in expressions formed by
5167 and'ing sub-expressions.

5188 documentation.
5190 2017-04-25 Arnaud Charlet <charlet@adacore.com>
5192 * exp_ch4.adb (Expand_N_Case_Expression): Emit error message when
5193 generating C code on complex case expressions.
5195 2017-04-25 Arnaud Charlet <charlet@adacore.com>
5197 * sem_prag.adb (Analyze_Pragma): Generate a warning instead
5198 of silently ignoring pragma Ada_xxx in Latest_Ada_Only mode.
5199 * directio.ads, ioexcept.ads, sequenio.ads, text_io.ads: Use
5200 Ada_2012 instead of Ada_2005 to be compatible with the above
5201 change.
5202 * bindgen.adb: Silence new warning on pragma Ada_95.
5204 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5206 * checks.adb (Generate_Range_Check): Revert part of previous change.
5208 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5210 * sem_ch4.adb (Try_Container_Indexing): Handle properly a
5211 container indexing operation that appears as a an actual in a
5212 parameter association in a procedure call.
5214 2017-04-25 Olivier Ramonat <ramonat@adacore.com>
5216 * prj-proc.adb, sem_util.adb, s-stposu.adb, sem_attr.adb, prj-conf.ads:
5217 Fix spelling mistakes.
5219 2017-04-25 Bob Duff <duff@adacore.com>
5221 * types.ads, osint.adb, sinput-c.adb, sinput-d.adb, sinput-l.adb,
5222 * sinput-p.adb: Use regular fat pointers, with bounds checking,
5223 for source buffers. Fix misc obscure bugs.
5224 * sinput.ads, sinput.adb: Use regular fat pointers, with bounds
5225 checking, for source buffers. Modify representation clause for
5226 Source_File_Record as appropriate. Move Source_File_Index_Table
5227 from spec to body, because it is not used outside the body.
5228 Move Set_Source_File_Index_Table into the private part, because
5229 it is used only in the body and in children. Use trickery to
5230 modify the dope in the generic instantiation case. It's ugly,
5231 but not as ugly as the previous method. Fix documentation.
5232 Remove obsolete code.
5233 * fname-sf.adb, targparm.adb: Fix misc out-of-bounds
5234 indexing in source buffers.
5235 * fmap.adb: Avoid conversions from one string type to another.

5247 (Generate_Range_Check): Do not generate a range check when the
5248 expander is not active or when index/range checks are suppressed
5249 on the target type.
5250 (Insert_List_After_And_Analyze, Insert_List_Before_And_Analyze):
5251 Remove variants that include a Supress parameter. These routines
5252 are never used, and were introduced before the current scope-based
5253 check suppression method.
5255 2017-04-25 Vasiliy Fofanov <fofanov@adacore.com>
5257 * prj-part.adb, cstreams.c, osint.adb, osint.ads: Remove VMS specific

5270 (Known_Null): Moved to Sem_Util.
5271 * sem_util.adb Add new enumeration type Null_Status_Kind.
5272 (Known_Non_Null): Moved from Exp_Util. Most of the logic in
5273 this routine is now carried out by Null_Status.
5274 (Known_Null): Moved from Exp_Util. Most of the logic in this routine
5275 is now carried out by Null_Status.
5276 (Null_Status): New routine.
5277 * sem_util.ads (Known_Non_Null): Moved from Exp_Util.
5278 (Known_Null): Moved from Exp_Util.
5280 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5282 * sem_ch6.adb (Analyze_Expression_Function): Do not report an
5283 error on the return type of an expression function that is a
5284 completion, if the type is derived from a generic formal type.
5286 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5288 * sem_dim.adb (Dimensions_Of_Operand): The dimensions of a type
5289 conversion are those of the target type.
5291 2017-04-25 Bob Duff <duff@adacore.com>
5293 * a-clrefi.adb: Minor cleanup.

5302 types.adb, types.ads, types.h, sinput-l.adb, targparm.adb,
5303 errout.adb, sinput.adb, sinput.ads, cstand.adb, scn.adb,
5304 scn.ads, gnatls.adb: Eliminate the vestigial Internal_Source_File and
5305 the Internal_Source buffer. This removes the incorrect call to "="
5306 the customer noticed.
5307 Wrap remaining calls to "=" in Null_Source_Buffer_Ptr. We
5308 eventually need to eliminate them altogether. Or else get rid
5309 of zero-origin addressing.
5311 2017-04-25 Claire Dross <dross@adacore.com>
5313 * exp_util.ads (Expression_Contains_Primitives_Calls_Of): New
5314 function used in GNATprove to know if an expression contains

5867 * prj-attr.adb, snames.ads-tmpl: Add package Install's
5868 Required_Artifacts attribute.
5870 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5872 * sem_util.adb (Same_Value): String literals are compile-time
5873 values, and comparing them must use Expr_Value_S.
5875 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5877 * sem_ch4.adb (Complete_Object_Interpretation): If an explicit
5878 dereference is introduced for the object, and the object is
5879 overloaded, do not check whether it is aliased, because it may
5880 include an implicit dereference.
5881 * sem_type.adb (Disambiguate): If two interpretations are access
5882 attribute types with the same designated type keep either of
5883 them and do not report an ambiguity. A true ambiguity will be
5884 reported elsewhere.
5886 2017-04-25 Bob Duff <duff@adacore.com>
5888 * a-numeri.ads: Change the encoding of Greek letter Pi from
5889 brackets encoding to UTF-8. Use pragma Wide_Character_Encoding
5890 to indicate the encoding. We considered using a byte order mark
5891 (BOM), but that causes various trouble (misc software eats the
5892 BOM, if you have a patch with a BOM, then it's not at the start
5893 of the patch, so it's not a BOM, the BOM affects with-ing files,
5894 etc.).
5895 * scng.adb, s-wchcnv.adb: Minor.
5897 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5899 * sem_ch3.adb, sem_ch8.adb, sem_disp.adb: Minor reformatting.

5907 moved here from sem_ch3.
5908 * sem_ch8.adb (Analyze_Subprogram_Renaming): Implement legality
5909 check given in RM 6.1.1 (17) concerning renamings of overriding
5910 operations that inherits class-wide preconditions from ancestor
5911 or progenitor.

5925 when exceptions are allowed.
5926 (Process_Transients_In_Scope): Update the initialization of
5927 Exceptions_OK.
5928 * exp_util.ads, exp_util.adb (Exceptions_In_Finalization_OK): New
5929 routine.
5930 * sem_ch11.adb (Analyze_Exception_Handlers): Do not check any
5931 restrictions when the handler is internally generated and the
5932 mode is warnings.
5934 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5936 * sem_ch3.adb (Has_Non_Trivial_Precondition): New predicate to
5937 enforce legality rule on classwide preconditions inherited from
5938 both an ancestor and a progenitor (RM 6.1.1 (10-13).
5939 * sem_disp.adb (Check_Dispatching_Context): A call to an abstract
5940 subprogram need not be dispatching if it appears in a precondition
5941 for an abstract or null subprogram.
5943 2017-04-25 Gary Dismukes <dismukes@adacore.com>
5945 * sem_ch10.adb: Minor typo fix.
5947 2017-04-25 Arnaud Charlet <charlet@adacore.com>
5949 * gcc-interface/Makefile.in: Cleanup VxWorks targets.
5951 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
5953 * fname.adb (Is_Internal_File_Name): Arrange for the slices to
5954 have a length which is a power of 2.
5955 (Is_Predefined_File_Name): Likewise. Adjust comment.
5957 2017-04-25 Bob Duff <duff@adacore.com>
5959 * exp_aggr.adb (Component_Count): Protect the
5960 arithmetic from attempting to convert a value >= 2**31 to Int,
5961 which would otherwise raise Constraint_Error.
5963 2017-04-25 Bob Duff <duff@adacore.com>
5965 * opt.ads (Locking_Policy): Fix incorrect documentation. The
5966 first character of the policy name is not unique.
5968 2017-04-25 Bob Duff <duff@adacore.com>
5970 * s-fileio.adb (Name): Raise Use_Error if the file is a temp file.
5971 * s-ficobl.ads (Is_Temporary_File): Remove incorrect comment
5972 about this flag not being used. It was already used, and it is
5973 now used more.
5975 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5977 * einfo.adb Flag301 is now known as Ignore_SPARK_Mode_Pragmas.

5987 Ignore_SPARK_Mode_Pragmas_In_Instance.
5988 * sem_ch6.adb (Analyze_Subprogram_Body_Helper):
5989 Save and restore the value of global flag
5990 Ignore_SPARK_Mode_Pragmas_In_Instance. Set or reinstate the value
5991 of global flag Ignore_SPARK_Mode_Pragmas_In_Instance when either
5992 the corresponding spec or the body must ignore all SPARK_Mode
5993 pragmas found within.
5994 (Analyze_Subprogram_Declaration): Mark
5995 the spec when it needs to ignore all SPARK_Mode pragmas found
5996 within to allow the body to infer this property in case it is
5997 instantiated or inlined later.
5998 * sem_ch7.adb (Analyze_Package_Body_Helper): Save and restore the
5999 value of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Set
6000 the value of global flag Ignore_SPARK_Mode_Pragmas_In_Instance
6001 when the corresponding spec also ignored all SPARK_Mode pragmas
6002 found within.
6003 (Analyze_Package_Declaration): Mark the spec when
6004 it needs to ignore all SPARK_Mode pragmas found within to allow
6005 the body to infer this property in case it is instantiated or
6006 inlined later.
6007 * sem_ch12.adb (Analyze_Formal_Package_Declaration):
6008 Save and restore the value of flag
6009 Ignore_SPARK_Mode_Pragmas_In_Instance. Mark the
6010 formal spec when it needs to ignore all SPARK_Mode
6011 pragmas found within to allow the body to infer this
6012 property in case it is instantiated or inlined later.
6013 (Analyze_Package_Instantiation): Save and restore the value
6014 of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Mark
6015 the instance spec when it needs to ignore all SPARK_Mode
6016 pragmas found within to allow the body to infer this
6017 property in case it is instantiated or inlined later.
6018 (Analyze_Subprogram_Instantiation): Save and restore the value
6019 of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Mark the
6020 instance spec and anonymous package when they need to ignore
6021 all SPARK_Mode pragmas found within to allow the body to infer

6023 (Instantiate_Package_Body): Save and restore the value of global
6024 flag Ignore_SPARK_Mode_Pragmas_In_Instance. Set the value of
6025 global flag Ignore_SPARK_Mode_Pragmas_In_Instance when the
6026 corresponding instance spec also ignored all SPARK_Mode pragmas
6027 found within.
6028 (Instantiate_Subprogram_Body): Save and restore the
6029 value of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Set

6038 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
6040 * bindgen.adb, exp_dbug.adb, errout.adb, fname.adb: Minor reformatting.
6042 2017-04-25 Bob Duff <duff@adacore.com>
6044 * exp_atag.adb (Build_CW_Membership): Add "Suppress =>
6045 All_Checks" to avoid generating unnecessary checks.
6046 * exp_ch4.adb (Expand_N_In, Make_Tag_Check): Add "Suppress =>
6047 All_Checks".
6048 * sem.ads: Fix comment.
6049 * expander.ads: Fix comment.
6050 * exp_atag.ads: Fix comment: "Index = 0" should be
6051 "Index >= 0".
6053 2017-04-25 Gary Dismukes <dismukes@adacore.com>
6055 * s-taprop-linux.adb: Minor editorial fixes.
6057 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
6059 * sem_util.adb (New_Copy_Tree): Put back the declarations of the
6060 hash tables at library level. Reinstate the NCT_Hash_Tables_Used
6061 variable and set it to True whenever the main hash table is
6062 populated. Short- circuit the Assoc function if it is false
6063 and add associated guards.
6065 2017-04-25 Olivier Hainque <hainque@adacore.com>
6067 * bindgen.adb (Gen_Elab_Calls): Also update counter of lone
6068 specs without elaboration code that have an elaboration counter
6069 nevertheless, e.g. when compiled with -fpreserve-control-flow.
6070 * sem_ch10.adb (Analyze_Compilation_Unit):
6071 Set_Elaboration_Entity_Required when requested to preserve
6072 control flow, to ensure the unit elaboration is materialized at
6073 bind time, resulting in the inclusion of the unit object file
6074 in the executable closure at link time.
6076 2017-04-25 Pierre-Marie de Rodat <derodat@adacore.com>
6078 * exp_dbug.adb: In Debug_Renaming_Declaration,
6079 when dealing with indexed component, accept to produce a renaming
6080 symbol when the index is an IN parameter or when it is a name
6081 defined in an outer scope.
6083 2017-04-25 Yannick Moy <moy@adacore.com>
6085 * errout.adb (Error_Msg): Adapt continuation
6086 message in instantiations and inlined bodies for info messages.
6088 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
6090 * fname.adb (Has_Internal_Extension): Add pragma Inline.
6091 Use direct 4-character slice comparisons.
6092 (Has_Prefix): Add
6093 pragma Inline. (Has_Suffix): Delete.
6094 (Is_Internal_File_Name):
6095 Test Is_Predefined_File_Name first.
6096 (Is_Predefined_File_Name):
6097 Use direct slice comparisons as much as possible and limit all
6098 comparisons to at most 8 characters.
6100 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
6102 * checks.adb (Insert_Valid_Check): Code cleanup.
6103 * exp_ch6.adb (Add_Validation_Call_By_Copy_Code): New routine.
6104 (Expand_Actuals): Generate proper copy-back for a validation
6105 variable when it acts as the argument of a type conversion.
6106 * sem_util.adb (Is_Validation_Variable_Reference): Augment the
6107 predicate to operate on type qualifications.
6109 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
6111 * sem_prag.adb, exp_ch6.adb, binde.adb, sem_disp.adb, s-fileio.adb:
6112 Minor reformatting.
6114 2017-04-25 Bob Duff <duff@adacore.com>
6116 * sem_prag.adb (No_Return): Give an error if the pragma applies
6117 to a body. Specialize the error for the specless body case,
6118 as is done for (e.g.) pragma Convention.
6119 * debug.adb: Add switch -gnatd.J to disable the above legality
6120 checks. This is mainly for use in our test suite, to avoid
6121 rewriting a lot of illegal (but working) code. It might also
6122 be useful to customers. Under this switch, if a pragma No_Return
6123 applies to a body, and the procedure raises an exception (as it
6124 should), the pragma has no effect. If the procedure does return,
6125 execution is erroneous.
6127 2017-04-25 Bob Duff <duff@adacore.com>
6129 * exp_ch6.adb (Expand_Actuals): This is the
6130 root of the problem. It took N as an 'in out' parameter, and in
6131 some cases, rewrote N, but then set N to Original_Node(N). So
6132 the node returned in N had no Parent. The caller continued
6133 processing of this orphaned node. In some cases that caused a
6134 crash (e.g. Remove_Side_Effects climbs up Parents in a loop,
6135 and trips over the Empty Parent). The solution is to make N an
6136 'in' parameter. Instead of rewriting it, return the list of
6137 post-call actions, so the caller can do the rewriting later,
6138 after N has been fully processed.
6139 (Expand_Call_Helper): Move most of Expand_Call here. It has
6140 too many premature 'return' statements, and we want to do the
6141 rewriting on return.
6142 (Insert_Post_Call_Actions): New procedure to insert the post-call
6143 actions in the appropriate place. In the problematic case,
6144 that involves rewriting N as an Expression_With_Actions.
6145 (Expand_Call): Call the new procedures Expand_Call_Helper and
6146 Insert_Post_Call_Actions.
6148 2017-04-25 Ed Schonberg <schonberg@adacore.com>
6150 * sem_prag.adb (Inherits_Class_Wide_Pre): Cleanup code, handle
6151 properly type derived from generic formal types, to handle
6152 properly modified version of ACATS 4.1B B611017.
6154 2017-04-25 Javier Miranda <miranda@adacore.com>
6156 * exp_unst.adb (Subp_Index): Adding missing
6157 support for renamings and functions that return a constrained
6158 array type (i.e. functions for which the frontend built a
6159 procedure with an extra out parameter).
6161 2017-04-25 Pascal Obry <obry@adacore.com>
6163 * s-string.adb: Minor code clean-up.
6165 2017-04-25 Bob Duff <duff@adacore.com>
6167 * s-os_lib.ads, s-os_lib.adb (Non_Blocking_Wait_Process): New
6168 procedure.
6169 * adaint.h, adaint.c (__gnat_portable_no_block_wait): C support
6170 function for Non_Blocking_Wait_Process.
6172 2017-04-25 Bob Duff <duff@adacore.com>
6174 * prep.adb (Preprocess): Remove incorrect
6175 Assert. Current character can be ASCII.CR.
6177 2017-04-25 Ed Schonberg <schonberg@adacore.com>
6179 * sem_prag.adb (Set_Convention_From_Pragma): Cleanup code for
6180 convention Stdcall, which has a number of exceptions. Convention
6181 is legal on a component declaration whose type is an anonymous
6182 access to subprogram.
6184 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
6186 * sem_ch4.adb: sem_ch4.adb Various reformattings.
6187 (Try_One_Prefix_Interpretation): Use the base type when dealing
6188 with a subtype created for purposes of constraining a private
6189 type with discriminants.
6191 2017-04-25 Javier Miranda <miranda@adacore.com>
6193 * einfo.ads, einfo.adb (Has_Private_Extension): new attribute.
6194 * warnsw.ads, warnsw.adb (All_Warnings): Set warning on late
6195 dispatching primitives (Restore_Warnings): Restore warning on
6196 late dispatching primitives (Save_Warnings): Save warning on late
6197 dispatching primitives (Do_Warning_Switch): Use -gnatw.j/-gnatw.J
6198 to enable/disable this warning.
6199 (WA_Warnings): Set warning on late dispatching primitives.
6200 * sem_ch3.adb (Analyze_Private_Extension_Declaration): Remember
6201 that its parent type has a private extension.
6202 * sem_disp.adb (Warn_On_Late_Primitive_After_Private_Extension):
6203 New subprogram.
6204 * usage.adb: Document -gnatw.j and -gnatw.J.
6206 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
6208 * exp_ch7.adb, checks.adb, sem_prag.adb, eval_fat.adb: Minor
6209 reformatting.
6211 2017-04-25 Bob Duff <duff@adacore.com>
6213 * binde.adb (Validate): Do not pass dynamic strings
6214 to pragma Assert, because older compilers do not support that.
6216 2017-04-25 Bob Duff <duff@adacore.com>
6218 * s-fileio.adb (Close): When a temp file is
6219 closed, delete it and clean up its Temp_File_Record immediately,
6220 rather than waiting until later.
6221 (Temp_File_Record): Add File
6222 component, so Close can know which Temp_File_Record corresponds
6223 to the file being closed.
6224 (Delete): Don't delete temp files,
6225 because they are deleted by Close.
6226 (Open): Set the File component
6227 of Temp_File_Record. This requires moving the creation of the
6228 Temp_File_Record to the end, after the AFCB has been created.
6230 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
6232 * checks.adb (Insert_Valid_Check): Do not generate
6233 a validity check when inside a generic.
6235 2017-04-25 Yannick Moy <moy@adacore.com>
6237 * sem_res.adb (Resolve_Type_Conversion): Fix bad logic.
6239 2017-04-25 Arnaud Charlet <charlet@adacore.com>
6241 * snames.ads-tmpl (Snames): More names for detecting predefined
6242 potentially blocking subprograms.
6244 2017-04-25 Ed Schonberg <schonberg@adacore.com>
6246 * sem_prag.adb (Analyze_Pre_Post_Condition): The rules
6247 concerning inheritance of class-wide preconditions do not apply
6248 to postconditions.
6250 2017-04-25 Bob Duff <duff@adacore.com>
6252 * s-ficobl.ads: Minor comment fix.
6254 2017-04-25 Yannick Moy <moy@adacore.com>
6256 * checks.adb (Apply_Scalar_Range_Check): Analyze precisely
6257 conversions from float to integer in GNATprove mode.
6258 (Apply_Type_Conversion_Checks): Make sure in GNATprove mode
6259 to call Apply_Type_Conversion_Checks, so that range checks
6260 are properly positioned when needed on conversions, including
6261 when converting from float to integer. (Determine_Range): In
6262 GNATprove mode, take into account the possibility of conversion
6263 from float to integer.
6264 * sem_res.adb (Resolve_Type_Conversion): Only enforce range
6265 check on conversions from fixed-point to integer, not anymore
6266 on conversions from floating-point to integer, when in GNATprove
6267 mode.
6269 2017-04-25 Yannick Moy <moy@adacore.com>
6271 * checks.adb (Determine_Range_R): Special case type conversions
6272 from integer to float in order to get bounds in that case too.
6273 * eval_fat.adb (Machine): Avoid issuing warnings in GNATprove
6274 mode, for computations involved in interval checking.
6276 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
6278 * checks.adb (Insert_Valid_Check): Partially reimplement validity
6279 checks.
6280 * einfo.adb Node36 is now used as Validated_Object.
6281 (Validated_Object): New routine.
6282 (Set_Validated_Object): New routine.
6283 (Write_Field36_Name): Add an entry for Validated_Object.
6284 * einfo.ads Add new attribute Validated_Object along with
6285 usage in entities.
6286 (Validated_Object): New routine along with pragma Inline.
6287 (Set_Validated_Object): New routine along with pragma Inline.
6288 * exp_attr.adb (Make_Range_Test): Add processing for validation
6289 variables to avoid extra reads and copies of the prefix.
6290 * exp_ch6.adb (Expand_Actuals): Add copy-back for validation
6291 variables in order to reflect any changes done in the variable
6292 back into the original object.
6293 * sem_util.adb (Is_Validation_Variable_Reference): New routine.
6294 * sem_util.ads (Is_Validation_Variable_Reference): New routine.
6296 2017-04-25 Steve Baird <baird@adacore.com>
6298 * exp_ch7.adb (Build_Array_Deep_Procs,
6299 Build_Record_Deep_Procs, Make_Finalize_Address_Body): Don't
6300 generate Finalize_Address routines for CodePeer.
6302 2017-04-25 Ed Schonberg <schonberg@adacore.com>
6304 * sem_prag.adb (Inherits_Class_Wide_Pre): subsidiary of
6305 Analyze_Pre_Post_Condition, to implement the legality checks
6306 mandated by AI12-0131: Pre'Class shall not be specified for an
6307 overriding primitive subprogram of a tagged type T unless the
6308 Pre'Class aspect is specified for the corresponding primitive
6309 subprogram of some ancestor of T.
6311 2017-04-25 Bob Duff <duff@adacore.com>
6313 * sem_ch8.adb (Use_One_Type): If a use_type_clause
6314 is redundant, set its Used_Operations to empty. This is only
6315 necessary for use clauses that appear in the parent of a generic
6316 child unit, because those use clauses get reanalyzed when we
6317 instantiate the generic, and we don't want the Used_Operations
6318 carried over from the original context (where it was probably
6319 not redundant).
6321 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
6323 * exp_ch6.adb: Minor reformatting.
6325 2017-04-25 Bob Duff <duff@adacore.com>

6329 * exp_prag.adb (Expand_Pragma_Check): Use Source_Index
6330 (Current_Sem_Unit) to find the correct casing.
6331 * par.adb (Par): Null out Current_Source_File, to ensure that
6332 the above bugs won't rear their ugly heads again.
6334 2017-04-25 Ed Schonberg <schonberg@adacore.com>
6336 * sem_ch8.adb (Find_Type): For an attribute reference
6337 'Class, if prefix type is synchronized and previous errors
6338 have suppressed the creation of the corresponding record type,
6339 create a spurious class-wide for the synchonized type itself,
6340 to catch other misuses of the attribute
6342 2017-04-25 Steve Baird <baird@adacore.com>
6344 * exp_ch6.adb (Expand_Simple_Function_Return): if CodePeer_Mode
6345 is True, then don't generate the accessibility check for the
6346 tag of a tagged result.
6347 * exp_intr.adb (Expand_Dispatching_Constructor_Call):
6348 if CodePeer_Mode is True, then don't generate the
6349 tag checks for the result of call to an instance of
6350 Ada.Tags.Generic_Dispatching_Constructor (i.e., both the "is a
6351 descendant of" check and the accessibility check).
6353 2017-04-25 Ed Schonberg <schonberg@adacore.com>
6355 * sem_ch13.adb: Code cleanups.
6356 * a-strbou.ads: minor whitespace fix in Trim for bounded strings.

6362 (Expand_Concatenate): When optimization is enabled, also expand
6363 the operation out-of-line if the concatenation is present within
6364 the expression of the declaration of a library-level object and
6365 not only if it is the expression of the declaration.
6367 2017-04-25 Bob Duff <duff@adacore.com>
6369 * freeze.adb (Freeze_Object_Declaration): Do
6370 not Remove_Side_Effects if there is a pragma Linker_Section,
6371 because in that case we want static initialization in the
6372 appropriate section.
6374 2017-04-25 Gary Dismukes <dismukes@adacore.com>
6376 * exp_dbug.adb: Minor rewording and reformatting.
6378 2017-04-25 Ed Schonberg <schonberg@adacore.com>
6380 * sem_attr.adb (Statically_Denotes_Object): New predicate, to
6381 handle the proposed changes to rules concerning potentially
6382 unevaluated expressions, to include selected components that
6383 do not depend on discriminants, and indexed components with
6384 static indices.
6385 * sem_util.adb (Is_Potentially_Unevaluated): Add check for
6386 predicate in quantified expression, and fix bugs in the handling
6387 of case expressions and membership test.
6388 (Analyze_Attribute_Old_Result): use new predicate.
6389 (Analyze_Attribute, case Loop_Entry): ditto.
6391 2017-04-25 Bob Duff <duff@adacore.com>
6393 * s-secsta.adb (SS_Info): Add a comment
6394 explaining why we don't need to walk all the chunks in order to
6395 compute the total size.
6397 2017-04-25 Bob Duff <duff@adacore.com>
6399 * namet.ads, namet.adb (Global_Name_Buffer): Increase the length
6400 of the global name buffer to 4*Max_Line_Length.
6402 2017-04-25 Javier Miranda <miranda@adacore.com>
6404 * exp_ch8.adb (Expand_N_Object_Renaming_Declaration): When creating a
6405 renaming entity for debug information, mark the entity as needing debug
6406 info if it comes from sources.
6408 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
6410 * sem_ch13.adb (Analyze_Attribute_Definition_Clause): Remove the
6411 restriction converning the use of 'Address where the prefix is
6412 of a controlled type.
6414 2017-04-25 Pierre-Marie de Rodat <derodat@adacore.com>
6416 * exp_dbug.adb: In Debug_Renaming_Declaration,
6417 skip slices that are made redundant by an indexed component
6418 access.
6419 * atree.h: New definition for Original_Node.
6421 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>

6425 2017-04-25 Ed Schonberg <schonberg@adacore.com>
6427 * sem_ch3.adb (Check_Entry_Contract): Call
6428 Preanalyze_Spec_Expression so that resolution takes place as well.
6429 * sem_util.adb (Check_Internal_Protected_Use): Reject properly
6430 internal calls that appear in preconditions of protected
6431 operations, in default values for same, and in contract guards
6432 for contract cases in SPARK.
6434 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
6436 * a-numaux.ads: Fix description of a-numaux-darwin
6437 and a-numaux-x86.
6438 (Double): Define to Long_Float.
6439 * a-numaux-vxworks.ads (Double): Likewise.
6440 * a-numaux-darwin.ads
6441 (Double): Likewise.
6442 * a-numaux-libc-x86.ads (Double): Define to Long_Long_Float.
6443 * a-numaux-x86.ads: Fix package description.
6444 * a-numaux-x86.adb (Is_Nan): Minor tweak.
6445 (Reduce): Adjust and complete description. Call Is_Nan instead of
6446 testing manually. Use an integer temporary to hold rounded value.
6447 * a-numaux-darwin.adb (Reduce): Likewise.
6448 (Is_Nan): New function.
6450 2017-04-25 Ed Schonberg <schonberg@adacore.com>
6452 * sem_ch4.adb (Analyze_Selected_Component): Additional refinement
6453 on analysis of prefix whose type is a current instance of a
6454 synchronized type, but where the prefix itself is an entity that
6455 is an object.
6457 2017-04-25 Ed Schonberg <schonberg@adacore.com>
6459 * exp_ch5.adb (Replace_Target): When rewriting the RHS, preserve
6460 the identity of callable entities therein, because they have been
6461 properly resolved, and prefixed calls may have been rewritten
6462 as normal calls.
6464 2017-04-25 Patrick Bernardi <bernardi@adacore.com>
6466 * exp_ch3.adb (Build_Init_Statements): Convert
6467 the expression of the pragma/aspect Secondary_Stack_Size to
6468 internal type System.Parameters.Size_Type before assigning
6469 it to the Secondary_Stack_Size component of the task type's
6470 corresponding record.
6472 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
6474 * sem_eval.adb (Compile_Time_Compare): Reinstate the expr+literal

6476 are equal.
6478 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
6480 * s-osinte-freebsd.ads: Minor comment tweaks
6482 2017-04-25 Javier Miranda <miranda@adacore.com>
6484 * urealp.adb (UR_Write): Reverse previous patch
6485 adding documentation on why we generate multiplications instead
6486 of divisions (needed to avoid expressions whose computation with
6487 large numbers may cause division by 0).
6489 2017-04-25 Bob Duff <duff@adacore.com>
6491 * erroutc.adb (Set_Specific_Warning_Off,
6492 Set_Warnings_Mode_Off): Use the correct source file for
6493 Stop. Was using Current_Source_File, which is only valid during
6494 parsing. Current_Source_File will have a leftover value from
6495 whatever file happened to be parsed last, because of a with_clause
6496 or something.
6498 2017-04-25 Bob Duff <duff@adacore.com>
6500 * lib.ads, lib.adb (In_Internal_Unit): New functions similar
6501 to In_Predefined_Unit, but including GNAT units.
6502 * sem_util.ads, sem_util.adb (Should_Ignore_Pragma): Replace
6503 with Should_Ignore_Pragma_Par and Should_Ignore_Pragma_Sem,
6504 because Should_Ignore_Pragma was not working reliably outside
6505 the parser, because Current_Source_File is not valid.
6506 * sem_prag.adb, exp_prag.adb: Call Should_Ignore_Pragma_Sem.
6507 * par-prag.adb: Call Should_Ignore_Pragma_Par.

6516 * urealp.adb (UR_Write): Fix output of constants with a base other
6517 that 10.
6519 2017-04-25 Justin Squirek <squirek@adacore.com>
6521 * sem_ch13.adb (Get_Interfacing_Aspects): Moved to sem_util.adb.
6522 * sem_prag.adb (Analyze_Pragma, Process_Import_Or_Interface):
6523 Add extra parameter for Process_Interface_Name.
6524 (Process_Interface_Name): Add parameter for pragma to analyze
6525 corresponding aspect.
6526 * sem_util.ads, sem_util.adb (Get_Interfacing_Aspects): Added
6527 from sem_ch13.adb
6529 2017-04-25 Gary Dismukes <dismukes@adacore.com>
6531 * exp_ch7.adb, einfo.ads, sem_prag.adb: Minor reformatting and typo
6532 correction.

6536 * sem_res.adb (Resolve_Comparison_Op): Do not
6537 attempt evaluation of relational operations inside assertions.
6539 2017-04-25 Justin Squirek <squirek@adacore.com>
6541 * exp_util.adb (Add_Interface_Invariants):
6542 Restored, code moved back from Build_Invariant_Procedure_Body.
6543 (Add_Parent_Invariants): Restored, code moved back from
6544 Build_Invariant_Procedure_Body.
6545 (Build_Invariant_Procedure_Body):
6546 Remove refactored calls and integrated code from
6547 Add_Parent_Invariants and Add_Interface_Invariants.
6549 2017-04-25 Johannes Kanig <kanig@adacore.com>
6551 * errout.adb (Output_Messages): Adjust computation of total
6552 errors
6553 * erroutc.adb (Error_Msg): In statistics counts, deal
6554 correctly with informational messages that are not warnings.
6555 * errutil.adb (Finalize): adjust computation of total errors.
6557 2017-04-25 Arnaud Charlet <charlet@adacore.com trojanek>
6559 * terminals.c (__gnat_terminate_pid): New.

6566 2017-04-25 Justin Squirek <squirek@adacore.com>
6568 * sem_ch3.adb (Analyze_Declarations): Minor
6569 correction to comments, move out large conditional and scope
6570 traversal into a predicate.
6571 (Uses_Unseen_Lib_Unit_Priv): Predicate function made from extracted
6572 logic.
6574 2017-04-25 Ed Schonberg <schonberg@adacore.com>
6576 * sem_ch4.adb (Analyze_Selected_Component): Refine analysis
6577 of prefix whose type is a current instance of a synchronized
6578 type. If the prefix is an object this is an external call (or
6579 requeue) that can only access public operations of the object. The
6580 previous predicate was too restrictive, and did not allow public
6581 protected operations, only task entries.
6583 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
6585 * sem_ch5.adb, fname.adb: Minor reformatting.
6587 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
6589 * einfo.adb (Is_Anonymous_Access_Type): New routine.
6590 * einfo.ads Update the placement of
6591 E_Anonymous_Access_Subprogram_Type along with all subtypes that
6592 mention the ekind.
6593 (Is_Anonymous_Access_Type): New routine.
6594 * exp_ch7.adb (Allows_Finalization_Master): Do not generate a
6595 master for an access type subject to pragma No_Heap_Finalization.
6596 * exp_util.adb (Build_Allocate_Deallocate_Proc): An object being
6597 allocated or deallocated does not finalization actions if the
6598 associated access type is subject to pragma No_Heap_Finalization.
6599 * opt.ads Add new global variable No_Heap_Finalization_Pragma.
6600 * par-prag.adb Pragma No_Heap_Finalization does not need special
6601 processing from the parser.
6602 * sem_ch6.adb (Check_Return_Subtype_Indication): Remove ancient
6603 ??? comments. Use the new predicate Is_Anonymous_Access_Type.
6604 * sem_prag.adb Add an entry in table Sig_Flags for pragma
6605 No_Heap_Finalization.
6606 (Analyze_Pragma): Add processing for
6607 pragma No_Heap_Finalization. Update various error messages to
6608 use Duplication_Error.
6609 * sem_util.ads, sem_util.adb (No_Heap_Finalization): New routine.
6610 * snames.ads-tmpl: Add new predefined name No_Heap_Finalization
6611 and corresponding pragma id.
6613 2017-04-25 Bob Duff <duff@adacore.com>
6615 * freeze.adb (Freeze_Record_Type): Use the
6616 underlying type of the component type to determine whether it's
6617 elementary. For representation clause purposes, a private type
6618 should behave the same as its full type.
6619 * fname.ads, fname.adb (Is_Predefined_File_Name):
6620 Make sure things like "system.ali" are recognized as predefined.
6622 2017-04-25 Javier Miranda <miranda@adacore.com>
6624 * debug.adb: Update documentation of -gnatd.6.
6626 2017-04-25 Ed Schonberg <schonberg@adacore.com>
6628 * sem_ch5.adb (Preanalyze_Range): Handle properly an Ada2012
6629 element iterator when the name is an overloaded function call,
6630 one of whose interpretations yields an array.
6632 2017-04-25 Bob Duff <duff@adacore.com>
6634 * uname.ads, uname.adb (Is_Predefined_Unit_Name,
6635 Is_Internal_Unit_Name): New functions for operating on unit
6636 names, as opposed to file names. There's some duplicated code
6637 with fname.adb, which is unfortunate, but it seems like we don't
6638 want to add dependencies here.
6639 * fname-uf.adb (Get_File_Name): Change Is_Predefined_File_Name
6640 to Is_Predefined_Unit_Name; the former was wrong, because Uname
6641 is not a file name at all.
6642 * fname.ads, fname.adb: Document the fact that
6643 Is_Predefined_File_Name and Is_Internal_File_Name can be called
6644 for ALI files, and fix the code so it works properly for ALI
6645 files. E.g. these should return True for "system.ali".
6647 2017-04-25 Justin Squirek <squirek@adacore.com>
6649 * exp_util.adb (Add_Invariant): Removed,
6650 code moved to Add_Invariant_Check, Add_Inherited_Invariant,
6651 and Add_Own_Invariant. (Add_Invariant_Check): Used
6652 for adding runtime checks from any kind of invariant.
6653 (Add_Inherited_Invariant): Generates invariant checks for
6654 class-wide invariants (Add_Interface_Invariants): Removed, code
6655 moved to Build_Invariant_Procedure_Body (Add_Own_Invariant):
6656 Create a types own invariant procedure (Add_Parent_Invariants):
6657 Removed, code moved to Build_Invariant_Procedure_Body
6658 (Build_Invariant_Procedure_Body): Add refactored calls
6659 and integrated code from Add_Parent_Invariants and
6660 Add_Interface_Invariants.
6661 (Process_Type): Removed, the
6662 relavant code was inlined into both Add_Own_Invariant and
6663 Add_Inherited_Invariant.
6665 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
6667 * make.adb, par-ch2.adb, sem_util.adb, scans.ads, sem_ch8.adb,
6668 scn.adb, osint.adb, fname.adb: Minor reformatting.
6670 2017-04-25 Pascal Obry <obry@adacore.com>
6672 * s-taprop-mingw.adb: Do not check for CloseHandle in

6678 Continue to examine the context if the reference appears within
6679 an expression function.
6681 2017-04-25 Justin Squirek <squirek@adacore.com>
6683 * exp_ch7.adb, exp_ch7.ads Remove Build_Invariant_Procedure_Body
6684 and Build_Invariant_Procedure_Declaration.
6685 * exp_util.ads, exp_util.adb Add Build_Invariant_Procedure_Body
6686 and Build_Invariant_Procedure_Declaration from exp_ch7
6687 and break-out Is_Untagged_Private_Derivation from
6688 Build_Invariant_Procedure_Body.
6689 (Replace_Type_References):
6690 Append an extra parameter to allow for dispatching replacements
6691 and add the corrasponding logic.
6692 (Type_Invariant): Remove
6693 Replace_Typ_Refs and replace its references with calls to
6694 Replace_Type_References.
6695 * sem_ch3.adb, sem_prag.adb: Remove with and use of exp_ch7.
6697 2017-04-25 Bob Duff <duff@adacore.com>
6699 * sem_util.ads, sem_util.adb (Should_Ignore_Pragma): New function
6700 that returns True when appropriate.
6701 * par-prag.adb, exp_prag.adb, sem_prag.adb: Do not ignore pragmas
6702 when compiling predefined files.
6703 * fname.ads, fname.adb (Is_Predefined_File_Name): Fix bug:
6704 "gnat.adc" should not be considered a predefined file name.
6705 That required (or at least encouraged) a lot of cleanup of global
6706 variable usage. We shouldn't be communicating information via
6707 the global name buffer.
6708 * bindgen.adb, errout.adb, fname-uf.adb, lib-load.adb, make.adb,
6709 * restrict.adb, sem_ch10.adb, sem_ch6.adb, sem_ch8.adb: Changes
6710 required by the above-mentioned cleanup.
6712 2017-04-25 Ed Schonberg <schonberg@adacore.com>
6714 * osint.adb (Find_File): Handle properly a request for a
6715 configuration file whose name is a directory.
6717 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
6719 * sem_attr.adb, sem_ch5.adb: Minor reformatting.
6721 2017-04-25 Bob Duff <duff@adacore.com>

6724 * sem_ch8.adb: Minor comment fix.
6726 2017-04-25 Bob Duff <duff@adacore.com>
6728 * sem_prag.adb: Remove suspicious uses of Name_Buf.
6729 * stringt.ads, stringt.adb, exp_dbug.adb, sem_dim.adb: Remove
6730 Add_String_To_Name_Buffer, to avoid using the global Name_Buf.
6731 Add String_To_Name with no side effects.
6733 2017-04-25 Justin Squirek <squirek@adacore.com>
6735 * sem_ch3.adb (Analyze_Declarations): Add
6736 additional condition for edge case.
6738 2017-04-25 Bob Duff <duff@adacore.com>
6740 * par-ch2.adb, scans.ads, scn.adb: Do not give an error for
6741 reserved words inside pragmas. This is necessary to allow the
6742 pragma name Interface to be used in pragma Ignore_Pragma.
6743 * par.adb: Minor comment fix.
6745 2017-04-25 Javier Miranda <miranda@adacore.com>
6747 * a-tags.ads, a-tags.adb (Type_Is_Abstract): Renamed as Is_Abstract.
6748 * rtsfind.ads (RE_Type_Is_Abstract): Renamed as Is_Abstract.
6749 * exp_disp.adb (Make_DT): Update occurrences of RE_Type_Is_Abstract.
6750 * exp_intr.adb (Expand_Dispatching_Constructor_Call): Update
6751 occurrences of RE_Type_Is_Abstract

6762 2017-04-25 Doug Rupp <rupp@adacore.com>
6764 * sigtramp-vxworks-target.inc [PPC64]: Add a .localentry pseudo-op.
6766 2017-04-25 Ed Schonberg <schonberg@adacore.com>
6768 * sem_ch5.adb (Analyze_Assignment): Reset Full_Analysis flag on
6769 the first pass over an assignment statement with target names,
6770 to prevent the generation of subtypes (such as discriminated
6771 record components)that may carry the target name outside of the
6772 tree for the assignment. The subtypes will be generated when
6773 the assignment is reanalyzed in full.
6774 (Analyze_Target_Name): Handle properly class-wide types.
6776 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>

6782 type map used in class-wide semantics of assertion expressions.
6783 (Add_Inherited_Tagged_DIC): There is really no need to preanalyze
6784 and resolve the triaged expression because all substitutions
6785 refer to the proper entities. Update the replacement of
6786 references.
6787 (Build_DIC_Procedure_Body): Add formal parameter
6788 For_Freeze. Add local variable Build_Body. Inherited DIC pragmas
6789 are now only processed when freezing occurs. Build a body only
6790 when one is needed.
6791 (Entity_Hash): Removed.
6792 (Map_Types): New routine.
6793 (Replace_Object_And_Primitive_References): Removed.
6794 (Replace_References): New routine.
6795 (Replace_Type_References): Moved to the library level of Exp_Util.
6796 (Type_Map_Hash): New routine.

6804 (Update_Primitives_Mapping_Of_Types): Removed.
6805 * sem_ch7.adb (Preserve_Full_Attributes): Propagate the DIC
6806 properties of the private type to the full view in case the full
6807 view derives from a parent type and inherits a DIC pragma.
6808 * sem_prag.adb (Analyze_Pragma): Guard against a case where a
6809 DIC pragma is placed at the top of a declarative region.
6811 2017-04-25 Arnaud Charlet <charlet@adacore.com trojanek>
6813 * a-tasatt.adb: Complete previous change and use an unsigned
6814 int to avoid overflow checks.
6816 2017-04-25 Ed Schonberg <schonberg@adacore.com>
6818 * sem_attr.adb (Analyze_Attribute, case 'Access): Specialize
6819 the error message when the attribute reference is an actual in
6820 a call to a subprogram inherited from a generic formal type with
6821 unknown discriminants, which makes the subprogram and its formal
6822 parameters intrinsic (see RM 6.3.1 (8) and (13)).
6824 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
6826 * sem_aggr.adb, inline.adb, einfo.adb, einfo.ads, scng.adb,
6827 sem_prag.adb: Minor reformatting.
6829 2017-04-25 Bob Duff <duff@adacore.com>
6831 * sem_attr.adb (Type_Key): Add code in the
6832 recursive Compute_Type_Key to protect against fetching the source
6833 code for Standard, in case a component of the type is declared
6834 in Standard. There was already code to do this for the original
6835 type, but not for its components.
6837 2017-04-25 Javier Miranda <miranda@adacore.com>
6839 * exp_ch3.adb (Build_Initialization_Call): Handle
6840 subtypes of private types when searching for the underlying full
6841 view of a private type.

7533 (Check_Dependency_Clause): Properly detect a match between two
7534 'Result attributes. Update the various post-match cases to use
7535 Is_Already_Matched as this routine now automatically recognizes

7537 (Is_Already_Matched): New routine.
7538 (Remove_Extra_Clauses): New routine.
7539 (Report_Extra_Clauses): Remove the detection of ... => null

7579 to the expected type with the appropriate check flags set.
7580 * sem_res.adb (Resolve_Range): The higher bound can be in Typ's
7581 base type if the range is null. It may still be invalid if it

7598 subsidiary to Expand_N_Object_ Declaration, to compute a guard on
7599 an object declaration for an array type with a modular index type
7600 with the size of Long_Long_Integer. Special processing is needed
7601 in this case to compute reliably the size of the object, and
7602 eventually to raise Storage_Error, when wrap-around arithmetic
7603 might compute a meangingless size for the object.
7605 2017-01-23 Justin Squirek <squirek@adacore.com>
7607 * a-wtenau.adb, par-endh.adb, sem_prag.adb,

7612 * sem_res.adb (Resolve_Call): In the part of the code where
7613 it is deciding whether to turn the call into an indexed
7614 component, avoid doing so if the call is to an instance of
7615 Unchecked_Conversion. Otherwise, the compiler turns it into an
7616 indexed component, and resolution of that turns it back into a
7617 function call, and so on, resulting in infinite recursion.
7618 * sem_util.adb (Needs_One_Actual): If the first formal has a
7619 default, then return False.
7621 2017-01-21 Eric Botcazou <ebotcazou@adacore.com>

7666 * sem_ch13.adb (Analyze_Aspect_Specifications): Aspect Alignment
7667 must be treated as delayed aspect even if the expression is

7669 elaboration of the object to which it applies.
7671 2017-01-20 Tristan Gingold <gingold@adacore.com>
7673 * s-osinte-vxworks.ads (Interrup_Range): New subtype.

7721 returns a limited view of a type and at the point of the call the
7722 function is not declared in the extended main unit then replace
7723 it with the non-limited view, which must be available. If the
7724 called function is in the extended main unit then no action is
7725 needed since the back-end handles this case.
7727 2017-01-20 Eric Botcazou <ebotcazou@adacore.com>
7729 * sem_ch7.adb (Contains_Subp_Or_Const_Refs): Rename into...

7737 2017-01-20 Ed Schonberg <schonberg@adacore.com>
7739 * sem_ch3.adb (Complete_Private_Subtype): If the scope of the
7740 base type differs from that of the completion and the private
7741 subtype is an itype (created for a constraint on an access
7742 type e.g.), set Delayed_Freeze on both to prevent out-of-scope
7743 anomalies in gigi.
7745 2017-01-20 Hristian Kirtchev <kirtchev@adacore.com>
7747 * sem_ch6.adb (Analyze_Subprogram_Body_Helper):
7748 When inheriting the SPARK_Mode of a prior expression function,

7775 Dynamic_Predicate): If the entity E is a subtype that inherits
7776 a static predicate for its parent P,, the inherited and the

8038 * sem_ch3.adb (Analyze_Declarations): Minor reformatting.
8039 (Build_Derived_Enumeration_Type): If the derived type inherits a

8130 selected component has a prefix that might be interpreted
8131 as a parameterless function call, but none of the candidate
8132 interpretations is parameterless, and there is a hidden homonym
8133 of the prefix that is a package.

8152 (Traverse_Declaration_Or_Statement): fixed detection of

8154 statement alternatives rewritten to avoid testing if the first

8315 to Binde; that's more convenient.
8317 2017-01-13 Ed Schonberg <schonberg@adacore.com>
8319 * sem_ch6.adb (Analyze_Expression_Function): If the expression
8320 function is a completion, all entities referenced in the
8321 expression are frozen. As a consequence, a reference to an
8322 uncompleted private type from an enclosing scope is illegal.
8324 2017-01-13 Javier Miranda <miranda@adacore.com>
8326 * sem_ch6.adb (Freeze_Expr_Types): New subprogram.
8327 (Analyze_Subprogram_Body_Helper): At the occurrence of an
8328 expression function declaration that is a completion, its

8352 * sem_aggr.adb (Resolve_Array_Aggregate): The code that verifies
8353 the legality of An others clause applies as well to a choice in
8354 an Iterated_component_ association.
8355 (Resolve_Iterated_Component_Association): An others choice
8356 is legal.
8357 * exp_aggr.adb (Aggr_Assignment_OK_For_Backend): An
8358 Iterated_Component_Association is not static.
8360 2017-01-13 Hristian Kirtchev <kirtchev@adacore.com>
8362 * exp_ch3.adb (Freeze_Type): Mark the Ghost mode as set in case
8363 control is passed to the expresion handler before the new mode
8364 is set.
8365 * sem_ch12.adb (Analyze_Package_Instantiation,
8366 Analyze_Subprogram_Instantiation): Mark the Ghost mode as set
8367 in case control is passed to the expresion handler before the
8368 new mode is set.
8370 2017-01-13 Hristian Kirtchev <kirtchev@adacore.com>
8372 * sem_aggr.adb, sem_ch3.adb, inline.adb, sem_util.adb, exp_ch4.adb,

8385 Iterated_Component_Present.
8386 * exp_aggr.adb: Use Choice_List throughout, to handle
8387 Iterated_Component_Associations.
8388 (Gen_Loop): Generate proper loop for an
8389 Iterated_Component_Association: loop variable has the identifier
8390 of the original association. Generate a loop even for a single
8391 component choice, in order to make loop parameter visible in
8392 expression.
8393 (Flatten): An Iterated_Component_Association is not static.
8395 2017-01-13 Yannick Moy <moy@adacore.com>
8397 * exp_ch4.adb (Expand_N_Op_Expon): Ensure that the value of
8398 float exponentiation for statically known small negative values
8399 is the reciprocal of the exponentiation for the opposite value
8400 of the exponent.
8401 * s-exnllf.adb (Exn_Float, Exn_Long_Float, Exn_Long_Long_Float):
8402 Ensure that the value of float exponentiation for negative values

8406 for the number of generated gotos.
8408 2017-01-13 Yannick Moy <moy@adacore.com>

8412 expression in delay statement as OK for volatile context.
8414 2017-01-13 Ed Schonberg <schonberg@adacore.com>
8416 * sem_aggr.adb (Resolve_Array_Aggregate): In normal compilation
8417 mode a choice that is a subtype with a static predicate is
8418 replaced by the values it covers. This transformation must not
8419 be performed in ASIS mode, to preserve the source for analysis.
8421 2017-01-13 Justin Squirek <squirek@adacore.com>
8423 * nlists.ads: Correct minor typo.
8425 2017-01-13 Gary Dismukes <dismukes@adacore.com>

8431 * par-ch4.adb (P_Aggregate_Or_Parent_Expr): An
8432 Iterated_Component_Association is a named association in an
8433 array aggregate.
8434 * sem_aggr.adb (Resolve_Iterated_Component_Association): New
8435 procedure, subsidiary of Resolve_Array_Aggregate, to analyze
8436 and resolve the discrete choices and the expression of the
8437 new construct.
8438 * sinfo.adb, sinfo.ads: In analogy with N_Component_Association,
8439 Loop_Actions and Box_Present are attributes of
8440 N_Iterated_Component_Association nodes. Box_Present is always
8441 False in this case.
8442 * sprint.adb (Sprint_Node): An Iterated_Component_Association
8443 has a Discrete_Choices list, as specified in the RM. A
8444 Component_Association for aggregate uses instead a Choices list.
8445 We have to live with this small inconsistency because the new
8446 construct also has a defining identifier, and there is no way
8447 to merge the two node structures.
8449 2017-01-13 Yannick Moy <moy@adacore.com>

8459 Analyze_Declarations, to analyze and resolve the expressions of
8460 aspect specifications in the current declarative list, so that
8461 the expressions have proper entity and type info. This is needed
8462 for ASIS when there is no subsequent expansion to generate this
8463 semantic information.
8464 * sem_ch13.adb (Check_Aspect_At_End_Of_Declarations): Use Etype of
8465 original expression, to suppress cascaded errors when expression
8466 has been constant-folded.
8467 (Resolve_Aspect_Expressions, Resolve_Name): Preserve entities in
8468 ASIS mode, because there is no subsequent expansion to decorate
8469 the tree.
8471 2017-01-13 Yannick Moy <moy@adacore.com>
8473 * inline.adb, inline.ads (Call_Can_Be_Inlined_In_GNATprove_Mode):
8474 New function to detect when a call may be inlined or not in
8475 GNATprove mode.
8476 (Expand_Inlined_Call): Ensure that a temporary
8477 is always created in the cases where a type conversion may be
8478 needed on an input parameter in GNATprove mode, so that GNATprove
8479 sees the check to perform.
8480 * sem_res.adb (Resolve_Call): In GNATprove mode, skip inlining
8481 when not applicable due to actual requiring type conversion
8482 with possible check but no temporary value can be copied for
8483 GNATprove to see the check.

8582 function call is built when compiling the corresponding predicate
8583 function, but the expression has been found legal as a static
8584 predicate during earlier analysis.
8585 * sem_eval.adb (Real_Or_String_Static_Predicate_Matches): Handle
