125 2017-11-09 Pascal Obry <obry@adacore.com>
127 * libgnarl/s-taprop__mingw.adb: On Windows, initialize the thead handle
128 only for foreign threads. We initialize the thread handle only if not
129 yet initialized. This happens in Enter_Task for foreign threads only.
130 But for native threads (Ada tasking) we do want to keep the real
131 handle (from Create_Task) to be able to free the corresponding
132 resources in Finalize_TCB (CloseHandle).

150 the Offset_To_Top field of secondary dispatch tables when the dispatch
151 table is statically built.

168 * libgnarl/s-osinte__qnx.ads: Add some missing bindings to pthread.
169 * libgnarl/s-taprop__qnx.adb: New, derived from s-taprop__posix.adb. This brings
170 in particular a workaround with locks priority ceiling where a higher
171 priority task is allowed to lock a lower ceiling priority lock. This
172 also fixes the scheduling of FIFO tasks when the priority of a task is
174 * libgnat/system-qnx-aarch64.ads: Fix priority ranges.
176 2017-11-09 Yannick Moy <moy@adacore.com>

180 * gnatbind.adb (Scan_Bind_Arg): Simplify test to remove always true
182 * namet.adb (Copy_One_Character): Add assumption for static analysis,
183 as knowledge that Hex(2) is in the range 0..255 is too complex for
185 (Finalize): Add assumption for static analysis, as the fact that there
186 are symbols in the table depends on a global invariant at this point in
188 * set_targ.adb (Check_Spaces): Justify CodePeer false positive message.
189 * stylesw.adb (Save_Style_Check_Options): Rewrite to avoid test always

233 * freeze.adb (Check_Component_Storage_Order): Default initialize
234 Comp_Byte_Aligned rather than silencing messages with pragma
235 Warnings(Off), which does not work for CodePeer initialization
236 messages, and given that here the possible read of an unitialized value
237 depends on a proper use of parameters by the caller.
238 * inline.adb (Expand_Inlined_Call): Default initialize Lab_Decl, Targ.
239 * sem_ch12.adb (Build_Operator_Wrapper): Default initialize Expr.
240 * sem_ch3.adb (Build_Derived_Array_Type): Default initialize

244 (Analyze_Case_Expression): Rescope checking block within branch where
245 Others_Present is set by the call to Check_Choices.
246 * sem_ch5.adb (Analyze_Assignment): Default initialize
248 * sem_ch6.adb (Analyze_Function_Return): Default initialize Obj_Decl,
249 and restructure code to defend against previous errors, so that, in
250 that case, control does not flow to the elsif condition which read an
251 uninitialized Obj_Decl.
252 * sem_ch9.adb (Analyze_Requeue): Default initialize Synch_Type.
253 (Check_Interfaces): Default initialize Full_T_Ifaces and Priv_T_Ifaces,
254 which seem to be left uninitialized and possibly read in some cases.
255 * sem_dim.adb (Analyze_Aspect_Dimension_System): Retype Position more
256 precisely. This requires to exchange the test for exiting in case of
257 too many positions and the increment to Position, inside the loop.
258 * sem_eval.adb (Eval_Concatenation): Default initialize Folded_Val,
259 which cannot be read uninitialized, but the reasons for that are quite
261 * sem_intr.adb (Check_Intrinsic_Call): Default initialize Rtyp.
262 * sem_prag.adb (Collect_Subprogram_Inputs_Outputs): Default initialize
264 * sem_res.adb (Make_Call_Into_Operator): Default initialize Opnd_Type,
265 and test for presence of non-null Opnd_Type before testing its scope,
266 in a test which would read its value uninitialized, and is very rarely
267 exercized (it depends on the presence of an extension of System).
268 * sem_spark.ads: Update comment to fix name of main analysis procedure.
269 * sem_warn.adb (Warn_On_Known_Condition): Default initialize
271 * set_targ.adb (FailN): Mark procedure with No_Return.

279 * exp_ch11.adb (Possible_Local_Raise): Do not issue the warning for

299 when processing generic instances.
301 2017-11-09 Bob Duff <duff@adacore.com>
303 * namet.ads, namet.adb (Valid_Name_Id): New subtype that excludes
304 Error_Name and No_Name. Use this (versus Name_Id) to indicate which
305 objects can have those special values. Valid_Name_Id could usefully be
306 used all over the compiler front end, but that's too much trouble for
307 now. If we did that, we might want to rename:
308 Name_Id --> Optional_Name_Id, Valid_Name_Id --> Name_Id.
309 For parameters of type Valid_Name_Id, remove some redundant tests,
310 including the ones found by CodePeer. Use Is_Valid_Name instead of
311 membership test when appropriate.
312 (Error_Name_Or_No_Name): Delete this; it's no longer needed.
313 * sem_ch2.adb (Analyze_Identifier): Use "not Is_Valid_Name" instead of
314 "in Error_Name_Or_No_Name".

327 * lib-writ.adb (Write_ALI): Remove processing of the frontend xrefs as
328 part of the ALI writing; they are now processed directly from memory

376 * sem_res.adb (Resolve): If expression is an entity whose type has
377 implicit dereference, generate reference to it, because no reference is
378 generated for an overloaded entity during analysis, given that its
379 identity may not be known.

390 Set_Static_Offset_To_Top passing a negative offet-to-top value;
391 initialize also the offset-to-top field with a negative offset.
392 * libgnat/a-tags.adb (Base_Address): Displace the pointer by means of
393 an addition since the offset-to-top field is now a negative value.
394 (Displace): Displace the pointer to the object means of a substraction
395 since it is now a negative value.

1710 * sem_util.adb (Object_Access_Level): If the object is the return
1711 statement of an expression function, return the level of the function.
1712 This is relevant when the object involves an implicit conversion
1713 between access types and the expression function is a completion, which
1714 forces the analysis of the expression before rewriting it as a body, so
1715 that freeze nodes can appear in the proper scope.

1740 * exp_ch6.adb (Expand_N_Extended_Return_Statement): Add self-checking

1744 as for the other Is_B-I-P... functions.

1752 internally-generated call.

1755 was only for limited types.

1757 implies >= Ada 2005.

1786 actual for a formal package is an instantiation of a child unit, create
1787 a freeze node for the instance of the parent if it appears in the same
1788 scope and is not frozen yet.
1790 2017-10-09 Pierre-Marie de Rodat <derodat@adacore.com>
1792 * exp_atag.ads, libgnat/a-tags.adb, libgnat/a-tags.ads: Enhance

1795 2017-10-09 Bob Duff <duff@adacore.com>
1797 * exp_ch3.adb (Build_Assignment): Parameter name N was somewhat
1798 confusing. Same for N_Loc. Remove assumption that b-i-p implies
1799 limited. This is for the case of a function call that occurs as the
1800 default for a record component.
1801 (Expand_N_Object_Declaration): Deal with the case where expansion has
1802 created an object declaration initialized with something like

1808 * exp_attr.adb (Expand_Attribute_Reference, case 'Valid): The prefix of
1809 the attribute is an object, but it may appear within a conversion. The
1810 object itself must be retrieved when generating the range test that
1811 implements the validity check on a scalar type.

1872 (Is_Build_In_Place_Result_Type): New function to accompany
1873 Is_Build_In_Place_Function and Is_Build_In_Place_Function_Call, because
1874 sometimes we just have the type on our hands, not the function. For
1875 now, does the same thing as the old version, so build-in-place is
1876 disabled for nonlimited types, except that you can use -gnatd.9 to
1878 * exp_ch6.ads (Is_Build_In_Place_Result_Type): New function to
1879 accompany Is_Build_In_Place_Function and

1893 an unchecked conversion. Add assertions.

2982 * exp_aggr.adb: Add with & use clause for Urealp.
2983 (Aggr_Assignment_OK_For_Backend): Accept (almost all)
2984 elementary types instead of just discrete types.
2985 * sem_eval.adb (Expr_Value): Deal with N_Null for access types.
2986 * gcc-interface/trans.c (gnat_to_gnu) <N_Assignment_Statement>:
2987 Be prepared for the FP zero value in the memset case. Add small
2990 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
2992 * s-htable.adb (Static_HTable.Reset): Use aggregate instead
2995 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
2997 * exp_aggr.adb (Expand_Array_Aggregate): Use New_Copy_Tree instead
2998 of New_Copy because the latter leaves the syntactic structure of
2999 the tree inconsistent (a child is accessible through two parents)
3000 and prevents proper replication of itypes by subsequent calls
3002 * exp_ch4.adb (Expand_Concatenate): Use New_Copy_Tree instead of
3003 New_Copy because the latter leaves the syntactic structure of the
3004 tree inconsistent (a child is accessible through two parents)
3005 and prevents proper replication of itypes by subsequent calls
3007 * sem_util.adb (In_Subtree): New routine.
3008 (New_Copy_Tree): Reimplemented.
3009 * sem_util.ads (In_Subtree): New routine.
3010 (New_Copy_Tree): Reimplemented.
3012 2017-09-08 Ed Schonberg <schonberg@adacore.com>
3014 * sem_ch13.adb (Resolve_Aspect_Expressions): The expression
3015 for aspect Default_Value is a static scalar value, but it does
3016 not freeze the type. Yhis allows for subsequent representation
3017 clauses for the type.
3019 2017-09-08 Javier Miranda <miranda@adacore.com>
3021 * sem_ch8.adb (Find_Direct_Name.Undefined): Do
3022 not add entries into the undefined reference table when we are
3023 compiling with errors ignored.
3025 2017-09-08 Ed Schonberg <schonberg@adacore.com>
3027 * sem_ch12.adb (Check_Formal_Packages): Do not apply conformance
3028 check if the instance is within an enclosing instance body. The
3029 formal package was legal in the enclosing generic, and is
3030 legal in the enclosing instantiation. This optimisation may be
3031 applicable elsewhere, and it also removes spurious errors that
3032 may arise with on-the-fly processing of instantiations that
3033 contain Inline_Always subprograms.
3035 2017-09-08 Vincent Celier <celier@adacore.com>
3037 * gnatcmd.adb: Disregard empty argument of GNAT driver.
3039 2017-09-08 Justin Squirek <squirek@adacore.com>
3041 * checks.adb (Insert_Valid_Check): Manually decorate
3042 the generated temporary for range valdity checks.
3044 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3046 * usage.adb (Usage): Document new -gnatw.q/-gnatw.Q switches.
3048 2017-09-08 Justin Squirek <squirek@adacore.com>
3050 * switch-c.adb (Scan_Front_End_Switches): Add new warning switch
3051 case to handle underscore flags.
3052 * warnsw.adb, warnsw.ads (Set_Underscore_Warning_Switch): Create
3053 new procedure to handle underscores.
3055 2017-09-08 Javier Miranda <miranda@adacore.com>
3057 * exp_ch4.adb (Expand_N_Op_Divide): Reordering code that handles
3058 divisions with fixed point results to avoid generating twice
3059 the runtime check on divide by zero.
3060 * checks.adb (Apply_Divide_Checks): Ensure that operands are
3061 not evaluated twice (once for their runtime checks and once for
3062 their regular computation).
3064 2017-09-08 Yannick Moy <moy@adacore.com>
3066 * sem_prag.adb (Analyze_Part_Of): Add missing
3067 return statements after issuing errors. Add detection of
3068 out-of-order item and single concurrent type.

3198 when the actual is a construct that involves a dereference of an
3199 expression that includes a formal of the enclosing subprogram,
3200 In such cases, the accessibility level of the actual is that of
3201 the corresponding formal, which is passed in as an additional

3212 exceptions instead of crashes. Check for absurdly long strings
3213 and empty strings. Empty strings cause trouble because they can
3214 have super-null ranges (e.g. 100..10), which causes Ext_Copy to
3215 be empty, which causes an array index out of bounds.

3277 under -gnat2020 flag, given that it is a future feature of
3279 * sem_aggr.adb (Resolve_Iterated_Component_Association): Mark
3280 defining identifier as referenced to prevent spurious warnings:
3281 corresponding loop is expanded into one or more loops whose

3400 a completion instead of manually freezing the type of the
3402 (Analyze_Subprogram_Body_Helper): Do not call Freeze_Expr_Types here.
3404 2017-09-08 Ed Schonberg <schonberg@adacore.com>
3406 * exp_prag.adb (Replace_Discriminals_Of_Protected_Op):
3407 New procedure, auxiliary to Expand_Pragma_Check, to handle
3408 references to the discriminants of a protected type within a
3409 precondition of a protected operation. This is needed because
3410 the original precondition has been analyzed in the context of
3411 the protected declaration, but in the body of the operation
3412 references to the discriminants have been replaved by references
3413 to the discriminants of the target object, and these references
3414 are only created when expanding the protected body.
3416 2017-09-08 Yannick Moy <moy@adacore.com>
3418 * sem_prag.adb (Analyze_Pragma): Issue more precise error messages on
3421 2017-09-08 Ed Schonberg <schonberg@adacore.com>
3423 * exp_attr.adb (Build_Record_VS_Func): If the record is an
3424 unchecked union, do not emit checks for its (non-existent)
3425 discriminants, or for variant parts that depend on them.

3429 * sem_ch4.adb (Find_Equality_Types.Try_One_Interp,
3430 Find_Comparison_Type.Try_One_Interp): Add check for generic
3433 2017-09-08 Arnaud Charlet <charlet@adacore.com>
3435 * sem_ch3.adb, layout.adb, layout.ads, exp_attr.adb, debug.adb,
3436 exp_pakd.adb, sem_prag.adb, gnat1drv.adb, targparm.adb, targparm.ads,
3437 repinfo.adb, exp_ch6.adb, exp_aggr.adb, sem_eval.adb, sem_ch13.adb,
3438 exp_ch3.adb: Remove references to Frontend_Layout_On_Target and
3439 remaining references to AAMP_On_Target.
3441 2017-09-08 Ed Schonberg <schonberg@adacore.com>
3443 * style.adb: Fix typo.
3445 2017-09-08 Javier Miranda <miranda@adacore.com>
3447 * einfo.adb (Underlying_Type): Add missing support for class-wide
3448 types that come from the limited view.
3449 * exp_attr.adb (Attribute_Address): Check class-wide type
3450 interfaces using the underlying type to handle limited-withed
3452 (Attribute_Tag): Check class-wide type interfaces using
3453 the underlying type to handle limited-withed types.
3455 2017-09-08 Ed Schonberg <schonberg@adacore.com>
3457 * exp_ch5.adb (Expand_Predicated_Loop): Handle properly a loop
3458 over a subtype of a type with a static predicate, taking into
3459 account the predicate function of the parent type and the bounds
3460 given in the loop specification.
3461 * sem_ch3.adb (Inherit_Predicate_Flags): For qn Itype created for
3462 a loop specification that is a subtype indication whose type mark
3463 is a type with a static predicate, inherit predicate function,
3464 used to build case statement for rewritten loop.
3466 2017-09-08 Justin Squirek <squirek@adacore.com>
3468 * lib-load.adb: Modify printing of error message to exclude file
3471 2017-09-08 Arnaud Charlet <charlet@adacore.com>
3473 * inline.adb (Can_Be_Inlined_In_GNATprove_Mode):
3474 don't inline subprograms declared in both visible and private
3476 (In_Package_Spec): previously In_Package_Visible_Spec; now
3477 detects subprograms declared both in visible and private parts
3480 2017-09-08 Ed Schonberg <schonberg@adacore.com>
3482 * exp_util.adb (Build_Invariant_Procedure_Declaration): If
3483 the type is an anonymous array in an object declaration, whose
3484 component type has an invariant, use the object declaration
3485 as the insertion point for the invariant procedure, given that
3486 there is no explicit type declaration for an anonymous array type.
3488 2017-09-08 Bob Duff <duff@adacore.com>
3490 * a-cbprqu.ads, a-cbdlli.adb: Suppress warnings.

3499 source file is missing.
3501 2017-09-08 Bob Duff <duff@adacore.com>
3504 * a-textio.adb, a-witeio.adb, a-ztexio.adb (Set_WCEM): Use
3505 Default_WCEM by default (i.e. if the encoding is not specified
3506 by the Form string).
3508 2017-09-08 Bob Duff <duff@adacore.com>
3510 * s-trasym.ads (Hexa_Traceback): If
3511 Suppress_Hex is True, print "..." instead of a hexadecimal
3513 * s-trasym.adb: Ignore No_Hex in this version.
3516 2017-09-08 Bob Duff <duff@adacore.com>
3518 * debug.adb: Minor reformatting.
3520 2017-09-08 Bob Duff <duff@adacore.com>
3522 * a-cbdlli.adb, a-cohama.adb, a-cohase.adb (Copy): Rewrite the
3523 code so it doesn't trigger an "uninit var" warning.
3525 2017-09-08 Nicolas Roche <roche@adacore.com>
3527 * s-hibaen.ads: Remove obsolete file.
3529 2017-09-08 Arnaud Charlet <charlet@adacore.com>
3531 * a-locale.ads: Add comment explaining the state of this package.
3533 2017-09-08 Arnaud Charlet <charlet@adacore.com>

3537 * sem_prag.ads, sem_prag.adb (Find_Related_Declaration_Or_Body):
3538 allow calls in the context of package spec (for pragma
3539 Initializes) and bodies (for pragma Refined_State).
3541 2017-09-08 Bob Duff <duff@adacore.com>

3546 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3548 * debug.adb (dA): Adjust comment.
3549 * gnat1drv.adb (Gnat1drv): Likewise.
3550 * opt.ads (List_Representation_Info_Extended): New variable.
3551 * repinfo.adb (List_Record_Info): Split implementation into...
3552 (Compute_Max_Length): ...this. Recurse on records if requested.
3553 (List_Record_Layout): Likewise.
3554 * switch-c.adb (Scan_Front_End_Switches) <'R'>: Use case
3555 statement, accept '0' and set List_Representation_Info_Extended
3557 * usage.adb (Usage): Document new -gnatRe variant.
3559 2017-09-08 Ed Schonberg <schonberg@adacore.com>
3561 * sem_prag.adb (Analyze_Pragma, case Default_Storage_Pool):
3562 Do not save the given entity in the global variable Default_Pool
3563 if the pragma appears within a generic unit.
3565 2017-09-08 Bob Duff <duff@adacore.com>
3567 * errout.adb (Delete_Warning): Do not
3568 decrement Warnings_Treated_As_Errors. This is called before
3569 Warnings_Treated_As_Errors has been incremented to account for
3570 this warning. Decrementing it here can lead to negative values
3571 of Warnings_Treated_As_Errors, raising Constraint_Error in
3572 checks-on builds, and causing the compiler to return an error
3573 code in checks-off builds.
3575 2017-09-08 Arnaud Charlet <charlet@adacore.com>
3577 * sem_util.ads, sem_util.adb (Is_CCT_Instance): Only expect
3578 entities of named concurrent types as Ref_Id and not of anonymous
3579 concurrent objects (because callers already know when a conversion
3580 is necessary and can easily do it); also, do not expect protected
3581 types or protected objects as Context_Id (because no flow-related
3582 SPARK pragmas are attached there); reflect these changes in a
3583 more precise comment.
3585 2017-09-08 Olivier Hainque <hainque@adacore.com>
3587 * g-altive.ads: Add documentation.
3589 2017-09-08 Bob Duff <duff@adacore.com>

3592 * erroutc.ads: Comment fix.
3594 2017-09-08 Ed Schonberg <schonberg@adacore.com>
3596 * sem_ch12.adb (Validate_Array_Type_Instance): Suppress check
3597 for compatibility of component types of formal and actual in an
3598 instantiation of a child unit, when the component type of the
3599 formal is itself a formal of an enclosing generic.
3601 2017-09-08 Arnaud Charlet <charlet@adacore.com>
3603 * sem_util.ads, sem_util.adb (Is_CCT_Instance): moved from
3604 sem_prag.adb to make it available for GNATprove; for concurrent
3605 types replace custom scope climbing with Scope_Same_Or_Within; for
3606 single concurrent objects add scope climbing (with Scope_Within),
3607 which was not there (that's the primary semantic change of this
3608 commit); also, when comparing a single concurrent object with
3609 its corresponding concurrent type rely on equality of types,
3610 not of objects (because that's simpler to code).
3611 * sem_prag.adb (Is_CCT_Instance): lifted to sem_util.ads.
3612 (Analyze_Global_Item): adjust special-casing of references to the
3613 current instance of a concurrent unit in the Global contracts
3614 of task types and single tasks objects; similar for references
3615 in the protected operations and entries of protected types and
3616 single protected objects (in all these cases the current instance
3617 behaves as an implicit parameter and must not be mentioned in
3618 the Global contract).
3620 2017-09-08 Arnaud Charlet <charlet@adacore.com>
3622 * exp_ch6.adb (Expand_Call_Helper): Introduce temporary for
3623 function calls returning a record within a subprogram call,
3626 2017-09-08 Ed Schonberg <schonberg@adacore.com>
3628 * sem_ch8.adb (Find_Expanded_Name): Handle properly an expanded
3629 name that designates the current instance of a child unit in its
3630 own body and appears as the prefix of a reference to an entity
3631 local to the child unit.
3632 * exp_ch6.adb, freeze.adb, sem_ch3.adb, sem_prag.adb, sem_util.adb:
3635 2017-09-08 Yannick Moy <moy@adacore.com>

3642 * sem_warn.adb (Check_Unused_Withs): Remove test that disabled
3643 warnings on internal units in configurable run time mode.
3645 2017-09-08 Bob Duff <duff@adacore.com>
3647 * sem_ch3.adb (Build_Derived_Private_Type): Inherit
3648 representation items from interfaces that the derived type
3649 implements, not just from the parent type.
3650 * sem_util.ads, sem_util.adb (Abstract_Interface_List): Change
3651 this to return an empty list when there are no interfaces.
3652 * einfo.ads, sem_ch13.adb: Minor comment fixes.
3653 * sem_attr.adb: Minor comment fix.
3655 2017-09-08 Doug Rupp <rupp@adacore.com>

3662 * exp_ch4.adb (Expand_N_Allocator): Generate a
3663 call to Allocate_Any_Controlled when the allocation does not
3664 require any initialization.
3666 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
3668 * sem_util.adb (Copy_Node_With_Replacement):
3669 Update the Renamed_Object field of a replicated object renaming
3672 2017-09-08 Patrick Bernardi <bernardi@adacore.com>
3674 * exp_ch9.adb (Is_Pure_Barrier): Allow type
3675 conversions and components of objects. Simplified the detection
3676 of the Count attribute by identifying the corresponding run-time
3679 2017-09-08 Yannick Moy <moy@adacore.com>
3681 * exp_ch9.adb, exp_disp.adb, repinfo.adb, sem_ch12.adb, sem_dim.adb,
3682 sem_type.adb, sinfo.ads: Minor reformatting.
3684 2017-09-08 Ed Schonberg <schonberg@adacore.com>
3686 * freeze.adb (Has_Incomplete_Compoent): New predicate, subsidiary
3687 of Freeze_Profile, used to inhibit the freezing of the profile
3688 of an expression function declared within a nested package, when
3689 some type in the profile depends on a private type declared in
3690 an enclosing package.
3692 2017-09-08 Bob Duff <duff@adacore.com>
3694 * gnat1drv.adb (Gnat1drv): Do not set the Force_ALI_Tree_File flag in
3695 the subunit case. It's still OK to set it in the "missing subunits"
3696 case, because that won't cause the obsolete .ali files that cause
3699 2017-09-08 Bob Duff <duff@adacore.com>
3701 * sinput-l.adb: Remove unused "with Unchecked_Conversion;". It's
3702 unclear why this didn't cause a warning.
3703 * a-uncdea.ads, a-unccon.ads: Add "Ada." to names in the
3704 pragmas. It's unclear why this didn't cause an error.
3706 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
3708 * exp_spark.adb (Expand_SPARK_N_Object_Renaming_Declaration):
3710 (Expand_SPARK_Potential_Renaming): Code clean up.
3711 * sem_prag.adb (Analyze_Initialization_Item): Add a guard in case
3712 the item does not have a proper entity.

3730 * repinfo.adb (List_Record_Info): During first loop,
3731 do not override the normalized position and first bit
3732 if they have already been set. Move fallback code
3733 for the packed case to the case where it belongs.
3734 * sem_ch13.adb (Adjust_Record_For_Reverse_Bit_Order):
3735 Also adjust the normalized position of components.
3736 (Adjust_Record_For_Reverse_Bit_Order_Ada_95): Likewise.
3738 2017-09-08 Ed Schonberg <schonberg@adacore.com>
3740 * exp_disp.adb (Make_DT, Set_All_DT_Position): Handle properly
3741 the placement of a primitive operation O that renames an operation
3742 R declared in an inner package, and which is thus not a primitive
3743 of the dispatching type of O. In this case O is a new primitive
3744 and does not inherit its dispatch table position from R (which

3749 * sem_dim.adb (Analyze_Dimension_If_Expression,
3750 Analyze_Dimension_Case_Expression): new subprograms to verify
3751 the dimensional correctness of Ada2012 conditional expressions,
3752 and set properly the dimensions of the construct.
3753 * sem_res.adb (Resolve_If_Expression, Resolve_Case_Expression)):
3754 call Analyze_Dimension.

3764 * sem_ch12.adb (Check_Generic_Parent): New procedure within
3765 Analyze_Associations, to handle actual packages that depend on
3766 previous instances. If a package IAP that is an instantiation is
3767 used as an actual in a subsequent instantiation SI in the same
3768 scope, and IAP has a body, IAP must be frozen before SI. If
3769 the generic parent of IAP is itself declared in a previous
3770 instantiation in the same scope, that instantiation must also
3771 be frozen before SI.
3772 (Install_Body): Prevent double insertion of freeze node for
3775 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>

3783 * sem_ch13.adb (Analyze_Aspect_Specifications, case
3784 Linker_Section): If the aspect applies to an object declaration
3785 with explicit initialization, do not delay the freezing of the
3786 object, to prevent access-before-elaboration in the generated
3787 initialization code.
3789 2017-09-08 Ed Schonberg <schonberg@adacore.com>
3791 * a-wtdeio.adb (Put, all versions): Use Long_Long_Integer
3792 (Integer_Value (Item)) when the size of the fixed decimal type
3793 is larger than Integer.
3795 2017-09-07 Eric Botcazou <ebotcazou@adacore.com>
3798 * gcc-interface/decl.c (copy_and_substitute_in_layout): Put the fields
3799 in order of increasing position in more cases.

3827 in the external name of the elaboration flag. Required to fix
3828 the regressions introduced by the initial version of this patch.
3830 2017-09-07 Bob Duff <duff@adacore.com>
3832 * sem_ch6.adb (Analyze_Function_Return): Do not
3833 insert an explicit conversion to force the displacement of the
3834 "this" pointer to reference the secondary dispatch table in the
3835 case where the return statement is returning a raise expression,
3836 as in "return raise ...".

3860 to handle properly various cases of type conversions where the
3861 target type and/or the expression carry dimension information.
3862 (Dimension_System_Root); If a subtype carries dimension
3863 information, obtain the source parent type that carries the

3870 2017-09-07 Ed Schonberg <schonberg@adacore.com>
3872 * exp_attr.adb (Expand_N_Attribute_Reference, case 'Constrained):
3873 If the prefix is a reference to an object, rewrite it as an
3874 explicit dereference, as required by 3.7.2 (2) and as is done
3875 with most other attributes whose prefix is an access value.
3877 2017-09-07 Bob Duff <duff@adacore.com>

3889 Account for the case where the are no lists to insert, but the
3890 secondary stack still requires management.

3936 2017-09-07 Ed Schonberg <schonberg@adacore.com>
3938 * sem_ch10.adb (Remove_Private_With_Clause): If a private with
3939 clause for a unit U appears in a context that includes a regular
3940 with_clause on U, rewrite the redundant private clause into a null
3941 statement, rather than removing it altogether from the context,
3942 so that ASIS tools can reconstruct the original source.
3944 2017-09-07 Ed Schonberg <schonberg@adacore.com>
3946 * sem_ch13.adb (Check_Aspect_At_Freeze_Point): The expression
3947 for aspect Small can be of any real type (not only a universal

3997 generated in the IP routines by means of keeping separate
3998 the initialization of the object components from the
3999 initialization of its dispatch tables. (Init_Secondary_Tags):
4000 Adding new formal (Init_Tags_List) and adjusting calls to
4001 Ada.Tags.Set_Dynamic_Offset_To_Top since it has a new formal;
4002 adjusting also calls to Ada.Tags.Register_Interface_Offset
4003 because the type of one of its formals has been changed.
4004 * a-tags.ads, a-tags.adb (Register_Interface_Offset): Profile
4005 modified. Instead of receiving a pointer to an object this
4006 routine receives now a primary tag.
4007 (Set_Dyanic_Offset_To_Top): Profile modified. This routine receives an
4008 additional formal: the tag of the primary dispatch table.
4009 * exp_disp.ads (Elab_Flag_Needed): New subprogram.
4010 * exp_disp.adb (Elab_Flag_Needed): New subprogram.

4024 * sem_util.adb (Check_Part_Of_Reference): rename Conc_Typ to Conc_Obj
4025 (because it refers to the anonymous concurrent object, not its type);
4026 fix condition for emitting error message about task/protected type,
4028 2017-09-07 Bob Duff <duff@adacore.com>
4030 * binde.adb (Debug_Flag_Old): If both -do and -dp

4041 * sem_prag.adb (Find_Role): The Global_Seen flag
4042 is now consulted not only for abstract states and variables,
4043 but for all kinds of items.
4044 (Collect_Subprogram_Inputs_Outputs): Do not process formal
4045 generic parameters, because unlike ordinary formal parameters,
4046 generic formals only act as input/ outputs if they are explicitly
4047 mentioned in a Global contract.
4049 2017-09-07 Yannick Moy <moy@adacore.com>
4051 * ghost.adb (Check_Ghost_Context): Do not err on ghost code inside
4052 predicate procedure. Check predicate pragma/aspect with Ghost entity.
4053 * exp_ch6.adb, par-ch6.adb, sem_ch13.adb, sem_prag.adb; Minor
4056 2017-09-07 Ed Schonberg <schonberg@adacore.com>

4061 Copy_Dimensions_Of_Components after creating the copy of the

4064 derived recor type, copy the dikensions if any of each component
4065 of the parent record to the corresponding component declarations
4066 of the derived record. These expressions are used among other
4067 things as default values in aggregates with box associations.

4079 also mark the renamed subprogram as referenced.
4081 2017-09-07 Ed Schonberg <schonberg@adacore.com>
4083 * par-ch6.adb (P_Subprogram): Improve error message on null
4084 procedure with misplaced aspect specification, which the parser
4085 first attempts to interpret as a malformed expression function.
4087 2017-09-07 Gary Dismukes <dismukes@adacore.com>
4089 * sem_attr.adb (Analyze_Attribute_Old_Result):

4112 Make_Build_In_Place_Call_In_Anonymous_Context): Do not use the
4113 secondary stack for all functions that return limited tagged
4114 types -- just do it for dispatching calls. Misc cleanup.
4115 * sem_util.ads, sem_util.adb (Unqual_Conv): New function to
4116 remove qualifications and type conversions. Fix various bugs
4117 where only a single level of qualification or conversion was
4118 removed, so e.g. "T1'(T2'(X))" would incorrectly return "T2'(X)"
4120 * checks.adb, exp_util.ads, exp_util.adb, sem_res.adb: Misc related
4123 2017-09-07 Ed Schonberg <schonberg@adacore.com>
4125 * sem_ch6.adb (setr_Actual_Subtypes): Within a predicate function
4126 do not create actual subtypes that may generate further predicate
4128 * sem_ch13.adb (Build_Predicate_Functions): Indicate that entity
4129 of body is a predicate function as well.
4130 (Resolve_Aspect_Expressions, Resolve_Name): For a component
4131 association, only the expression needs resolution, not the name.
4132 (Resolve_Aspect_Expressions, case Predicates): Construct and
4133 analyze the predicate function declaration in the scope of the
4134 type, before making the type and its discriminants visible.
4136 2017-09-06 Eric Botcazou <ebotcazou@adacore.com>

4175 2017-09-06 Bob Duff <duff@adacore.com>
4177 * binde.adb (Find_Elab_Order): Do not run Elab_Old unless
4178 requested. Previously, the -do switch meant "run Elab_New and
4179 Elab_Old and use the order chosen by Elab_Old, possibly with
4180 debugging printouts comparing the two orders." Now it means
4181 "do not run Elab_New." This is of use if there are bugs that
4182 cause Elab_New to crash.
4183 (Elab_Position, Num_Chosen): Change type to Nat, to avoid various

4199 * freeze.adb (Freeze_Record_Type)
4200 <Sized_Component_Total_Round_RM_Size>: New local variable to
4201 accumulate the rounded RM_Size of components. Update it for
4202 every component whose RM_Size is statically known. Add missing
4203 guard to check that bit packing is really required before issuing
4204 the error about packing. Swap condition for clarity's sake.

4226 2017-09-06 Ed Schonberg <schonberg@adacore.com>
4228 * sem_ch5.adb (Analyze_Assigment): If the left-hand side is an
4229 entity of a mutable type and the right-hand side is a conditional
4230 expression, resolve the alternatives of the conditional using
4231 the base type of the target entity, because the alternatives
4232 may have distinct subtypes. This is particularly relevant if
4233 the alternatives are aggregates.
4235 2017-09-06 Ed Schonberg <schonberg@adacore.com>
4237 * checks.adb (Apply_Predicate_Check): If the expression is an
4238 aggregate that is the RHS of an assignment, apply the check to
4239 the LHS after the assignment, rather than to the aggregate. This
4240 is more efficient than creating a temporary for the aggregate,
4241 and prevents back-end crashes when the aggregate includes a
4242 dynamic "others' association.
4244 2017-09-06 Yannick Moy <moy@adacore.com>

4258 * sem_aux.adb (Is_Generic_Formal): Handle properly formal packages.

4262 2017-09-06 Gary Dismukes <dismukes@adacore.com>
4264 * errout.adb (Error_Msg): Separate the
4265 treatment for warning vs. style messages in inlinings and
4266 instantiations. Prevents blowups on calls to Warn_Insertion for
4267 style messages, which should not be called in that case because
4268 Warning_Msg_Char is not set.
4270 2017-09-06 Justin Squirek <squirek@adacore.com>
4272 * sem_prag.adb (Check_VFA_Conflicts): Created
4273 to group all Volatile_Full_Access checks relating to other
4274 representation pragmas (Mark_Component_Or_Object): Created
4275 to centeralize the flagging of attributes for the record type
4276 component case, a pragma applied individually to a component, and
4278 (Process_Atomic_Independent_Shared_Volatile):
4279 Add propagation of certain pragmas to record components and move

4295 * sem_ch12.adb (Copy_Generic_Node): When we copy a node
4296 that is a proper body corresponding to a stub, we defer the
4297 adjustment of the sloc until after the correct adjustment has
4298 been computed. Otherwise, Adjust_Instantiation_Sloc will ignore
4299 the adjustment, because it will be outside the range in (the old,
4300 incorrect) S_Adjustment.

4324 * exp_ch5.adb (Expand_Formal_Container_Loop): Add proper error

4326 directly changable by the user with the use of E_Loop_Parameter.
4327 * sem_ch5.adb (Analyze_Block_Statement): Revert previous change.

4399 missing case of controlled generalized indexing.
4400 (Is_Source_Object): Use routine Strip to remove indirections.
4401 (Strip): New routine.
4403 2017-09-06 Bob Duff <duff@adacore.com>
4405 * sysdep.c (__gnat_has_cap_sys_nice): If HAVE_CAPABILITY is defined,
4406 we include the proper header. Otherwise, we just declare the necessary
4407 things from the capabilities library. This is so we can build on
4408 machines without that library, while still enabling that library.
4409 At run time, we're using weak symbols, so __gnat_has_cap_sys_nice will
4410 simply return 0 if the library is not present, or not included

4426 has no parameter specification and no entry index, use the entry name
4427 as the end of the generated SCO statement.
4429 2017-09-06 Steve Baird <baird@adacore.com>
4431 * exp_util.adb (Side_Effect_Free): For CodePeer (only) treat
4432 uses of 'Image and related attributes as having side effects in
4433 order to avoid replicating such uses.

4645 that Ada.Command_Line contains modern Ada (the raise expression).
4646 * gnatbind.adb: Avoid dependence on
4647 Ada.Command_Line. Depend on System.Response_File instead

4786 of the right-hand side has stored constraint, use its values
4787 (except for those that are renamings of parent discriminants)
4788 to produce additional assignments for the discriminants of the
4789 left-hand side, which are invisible in the righ-hand side and
4790 not retrievable as selected components.
4792 2017-09-06 Ed Schonberg <schonberg@adacore.com>
4794 * sem_util.adb (Needs_One_Formal): The first formal of such a

4814 * sem_ch12.adb (Analyze_Subprogram_Instantiation): Propagate
4815 No_Return flag to instance if pragma applies to generic unit. This
4816 must be done explicitly because the pragma does not appear

4829 * exp_ch4.adb (Handle_Changed_Representation): For an untagged
4830 derived type with a mixture of renamed and constrained parent
4831 discriminants, the constraint for the target must obtain the
4832 discriminant values from both the operand and from the stored
4833 constraint for it, given that the constrained discriminants are
4834 not visible in the object.
4835 * exp_ch5.adb (Make_Field_Assign): The type of the right-hand
4836 side may be derived from that of the left-hand side (as in the
4837 case of an assignment with a change of representation) so the
4838 discriminant to be used in the retrieval of the value of the
4839 component must be the entity in the type of the right-hand side.

4868 in a set membership is an overloaded enumeration literal, and
4869 the type of the alternative is resolved from a previous one,
4870 replace the entity of the alternative as well as the type,
4871 to prevent inconsistencies between the entity and the type.

5458 * exp_ch3.adb (Freeze_Type): Do not generate an invariant
5459 procedure body for a local (sub)type declaration within a
5460 predicate function. Invariant checks do not apply to these, and
5461 the expansion of the procedure will happen in the wrong scope,
5462 leading to misplaced freeze nodes.
5464 2017-05-02 Ed Schonberg <schonberg@adacore.com>
5466 * exp_util.adb (Insert_Library_Level_Action): Use proper scope
5467 to analyze generated actions. If the main unit is a body,
5468 the required scope is that of the corresponding unit declaration.
5470 2017-05-02 Arnaud Charlet <charlet@adacore.com>
5472 * einfo.adb (Declaration_Node): flip branches of
5473 an IF statement to avoid repeated negations in its condition;
5474 no change in semantics, only to improve readability.

5478 * sem_case.adb: Remove extra spaces in parameter declarations.
5480 2017-05-02 Justin Squirek <squirek@adacore.com>
5482 * usage.adb: Replace space with hyphen ("run time" -> "run-time")

5503 * exp_disp.adb (Set_All_DT_Position, In_Predef_Prim_DT):
5504 Refine predicate for the case where the primitive operation
5505 is a renaming of equality. An overriding operation that is
5506 a user-defined renaming of predefined equality inherits its
5507 slot from the overridden operation. Otherwise it is treated
5508 as a predefined op and occupies the same predefined slot as
5509 equality. A call to it is transformed into a call to its alias,
5510 which is the predefined equality. A dispatching call thus uses
5511 the proper slot if operation is further inherited and called
5512 with class-wide arguments.
5514 2017-05-02 Justin Squirek <squirek@adacore.com>
5516 * errout.adb (Set_Msg_Text): Add a case to switch the message

5549 * exp_ch3.adb (Build_Initialization_Call): Generate a null
5550 statement if the initialization call is a null procedure, as
5551 can happen with a controlled type with no explicit Initialize
5552 procedure, or an array of such.
5553 * exp_ch7.adb (Process_Object_Declaration): For a type with
5554 controlled components that has a trivial Initialize procedure,

5591 2017-05-02 Gary Dismukes <dismukes@adacore.com>
5593 * checks.ads (Null_Exclusion_Static_Checks): Add Boolean
5594 parameter Array_Comp to indicate the case of an array object
5595 with null-excluding components.
5596 * checks.adb (Null_Exclusion_Static_Checks):
5597 Call Compile_Time_Constraint_Error instead of
5598 Apply_Compile_Time_Constraint_Error in the component case. Also
5599 call that when Array_Comp is True, with an appropriate warning for
5600 the array component case. Only create an explicit initialization
5601 by null in the case of an object of a null-excluding access type
5602 (and no longer do that in the component case).
5603 * sem_ch3.adb (Check_Component): Add a Boolean parameter
5604 Array_Comp defaulted to False. Pass Empty for the Comp
5605 actual when calling Null_Exclusion_Static_Checks in the case
5606 where Comp_Decl matches Object_Decl, because we don't have a
5607 component in that case. In the case of an object or component
5608 of an array type, pass True for Array_Comp on the recursive call

5613 * s-taprop-linux.adb (Prio_To_Linux_Prio): New function to correctly
5614 compute the linux priority from the Ada priority. Call this everywhere
5615 required. In particular, the previous version was not doing this
5616 computation when setting the ceiling priority in various places. It
5617 was just converting to C.int, which results in a ceiling that is off
5620 2017-05-02 Ed Schonberg <schonberg@adacore.com>

5641 dynamic allocation, so that the proper warning can be emitted
5642 when restriction No_Implicit_Heap_Allocation is in effect.

5654 visibility rules for equality operators that apply within an
5655 instantiation apply within an inlined body.

5722 * checks.adb, sem_ch3.adb, sem_ch6.adb: Minor reformatting.
5724 2017-05-02 Bob Duff <duff@adacore.com>
5726 * exp_attr.adb (Callable, Identity, Terminated): Use Find_Prim_Op
5727 to find primitive ops, instead of using an Identifier that will
5728 later be looked up. This is necessary because these ops are not
5729 necessarily visible at all places where we need to call them.
5730 * exp_util.ads: Minor comment fix.
5732 2017-05-02 Ed Schonberg <schonberg@adacore.com>
5734 * sem_ch6.adb (Fully_Conformant_Expressions): Two entity
5735 references are fully conformant if they are both expansions
5736 of the discriminant of a protected type, within one of the
5737 protected operations. One occurrence may be expanded into a
5738 constant declaration while the other is an input parameter to
5739 the corresponding generated subprogram.

5790 * sem_ch4.adb (Complete_Object_Operation): When rewriting the
5791 controlling actual in a prefixed call, preserve the original node

5843 that replaces Is_Exception_Safe, but has the opposite
5844 sense. Is_Exception_Safe was missing various cases -- calls inside
5845 a pragma Debug, calls inside an 'if' or assignment statement,
5846 etc. Might_Raise now walks the entire subtree looking for things
5848 * exp_ch9.adb (Is_Exception_Safe): Remove.
5849 (Build_Protected_Subprogram_Body): Replace call to
5850 Is_Exception_Safe with "not Might_Raise". Misc cleanup (use

5923 * sem_ch6.adb (Freeze_Type_Refs): For an interface conversion
5924 node between access types, freeze the designated type as well,
5925 so that dispatch table pointers are created in the proper scope,
5926 and not in the constructed body of the expression function.
5928 2017-04-28 Bob Duff <duff@adacore.com>
5930 * alloc.ads (Nodes_Initial): Go back to previous value. The large
5931 value makes large compilations faster, but small compilations slower.
5933 2017-04-28 Arnaud Charlet <charlet@adacore.com>
5935 * sem_util.adb: minor typos in Is_Child_Or_Sibling.
5937 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
5939 * erroutc.adb (Compilation_Errors): Do not consider info messages
5940 as suitable warnings when warnings must be treated as errors.
5941 * sem_ch7.adb (Analyze_Package_Specification): Do not consider
5942 internally-generated packages when outputting completion
5944 * errout.adb (Output_Messages): Do not consider info messages as

5951 * warnsw.ads: Minor fix for incorrect wording in comment.
5953 2017-04-28 Ed Schonberg <schonberg@adacore.com>
5955 * sem_res.adb (In_Instance_Code): New predicate in
5956 Valid_Conversion, to determine whether a type conversion appears
5957 as (or within) an actual for a formal object. Type conversions
5958 in instances are not rechecked in Valid_Conversion because
5959 visibility changes between generic location andi instance may
5960 lead to spurious errors, but conversions within an actual must be
5961 fully checked, and they are not fully resolved when pre-analyzing
5964 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
5966 * exp_ch6.adb (Expand_N_Extended_Return_Statement): Use
5967 New_Copy_Tree instead of Relocate_Node as any subsequent copies
5968 of the relocated node will have mangled Parent pointers.

5970 tables used in conjunction with entity and itype replication.
5971 (Visit_Entity): Rewrite the restriction on which entities

6007 (Save_Warnings): Likewise.
6008 (Set_Dot_Warning_Switch): Handle 'q' and 'Q' letters.
6009 * gcc-interface/decl.c (gnat_to_gnu_entity): Adjust call to
6010 components_to_record.
6011 (gnu_field_to_gnat): New function.
6012 (warn_on_field_placement): Likewise.

6014 parameters. Rename local variables and adjust recursive call.
6015 Rework final scan of the field list and implement warnings on the
6016 problematic placement of specific sorts of fields.

6025 * sem_intr.adb, sem_res.adb, sem_util.adb, sem_warn.adb, sprint.adb:
6026 For efficiency, cache results of Is_Internal_File_Name and
6027 Is_Predefined_File_Name in the Units table. This avoids a lot
6028 of repeated text processing.
6030 2017-04-27 Emmanuel Briot <briot@adacore.com>
6032 * g-comlin.adb (Sort_Sections): remove useless test.
6034 2017-04-27 Claire Dross <dross@adacore.com>
6036 * a-cfhase.adb, a-cfhase.ads (=): Generic parameter removed to
6037 allow the use of regular equality over elements in contracts.
6038 (Formal_Model): Ghost package containing model functions that are
6039 used in subprogram contracts.
6040 (Current_To_Last): Removed, model functions should be used instead.
6041 (First_To_Previous): Removed, model functions should be used instead.
6042 (Strict_Equal): Removed, model functions should be used instead.
6043 (No_Overlap): Removed, model functions should be used instead.
6044 (Equivalent_Keys): Functions over cursors are removed. They were
6045 awkward with explicit container parameters.
6046 * a-cforse.adb, a-cforse.ads (=): Generic parameter removed to
6047 allow the use of regular equality over elements in contracts.

6057 * gnat1drv.adb: Code cleanup.
6059 2017-04-27 Ed Schonberg <schonberg@adacore.com>
6061 * exp_util.adb (Replace_Entity): The prefix of a 'Result
6062 attribute reference in a post- condition is the subprogram to
6063 which the condition applies. If the condition is inherited
6064 by a type extension, the prefix becomes a reference to the
6065 inherited operation, but there is no need to create a wrapper
6066 for this operation, because 'Result is expanded independently
6067 when elaborating the postconditions.
6069 2017-04-27 Bob Duff <duff@adacore.com>
6071 * sinput.adb: Minor code cleanup.
6072 * namet.adb (Append): Create faster versions of

6078 * sem_util.ads, sem_util.adb (In_Parameter_Specification):
6079 Remove unused function.
6080 * alloc.ads (Nodes_Initial): Use a much larger value, because
6081 the compiler was spending a lot of time copying the nodes table
6082 when it grows. This number was chosen in 1996, so is rather out
6083 of date with current memory sizes. Anyway, it's virtual memory.
6084 Get rid of Orig_Nodes_...; use Node_... instead.
6085 * atree.adb (Lock): Do not release the Nodes tables; it's a
6087 Orig_Nodes_ ==> Nodes_
6088 * nlists.adb: Orig_Nodes_ ==> Nodes_
6089 * g-table.adb: Remove unused "with" clause.
6090 * g-table.ads, table.ads: Remove Big_Table_Type, which should
6091 not be used by clients.
6092 * g-dyntab.adb (Last_Allocated): New function

6119 processing for Ada 83 and instances.
6120 (Object_Access_Level): Merge the processing for indexed components
6121 and selected components.
6122 * uname.adb (Add_Node_Name): Merge the processing for stubs.

6133 of Expand_Dispatching_Call. If the denoted subprogram has a
6134 class-wide precondition, this is the only precondition that
6135 applies to the call, rather that the class-wide preconditions
6136 that may apply to the body that is executed. (This is specified
6139 2017-04-27 Yannick Moy <moy@adacore.com>
6141 * gnat1drv.adb (Adjust_Global_Switches): Issue
6142 a warning in GNATprove mode if the runtime library does not
6143 support IEEE-754 floats.

6147 * sem_prag.adb (Inherit_Class_Wide_Pre): If the parent operation
6148 is itself inherited it does not carry any contract information,
6149 so examine its parent operation which is its Alias.
6151 2017-04-27 Ed Schonberg <schonberg@adacore.com>
6153 * sem_attr.adb (Analyze_Attribute, case 'Image): In Ada2012 the
6154 prefix can be an object reference in which case Obj'Image (X)
6155 can only be interpreted as an indexing of the parameterless
6156 version of the attribute.
6157 * par-ch4.adb (P_Name): An attribute reference can be the prefix of
6158 an indexing or a slice operation if the attribute does not require
6159 parameters. In Ada2012 'Image also belongs in this category,
6160 and A'Image (lo .. hi) is legal and must be parsed as a slice.
6162 2017-04-27 Yannick Moy <moy@adacore.com>
6164 * exp_ch4.adb: Minor reformatting.
6165 * gnat1drv.adb (Adjust_Global_Switches): When in GNATprove mode,

6505 contains calls to other primitives.
6506 (Build_Class_Wide_Clone_Call); Build a call to the common
6507 class-wide clone of a subprogram with classwide conditions. The
6508 body of the subprogram becomes a wrapper for a call to the

6821 * exp_ch7.adb (Make_Transient_Block): Transient blocks do not need
6822 to manage the secondary stack when an enclosing scope already
6823 performs this functionality (aka relaxed management). Switch
6824 -gnatd.s may be used to force strict management in which case
6825 the block will manage the secondary stack unconditionally. Add
6826 a guard to stop the traversal when encountering a package or a

6831 * sem_res.adb (Resolve_Call): Refine further the handling of
6832 limited views of return types in function calls. If the function
6833 that returns a limited view appears in the current unit,
6834 we do not replace its type by the non-limited view because
6835 this transformation is performed int the back-end. However,
6836 the type of the call itself must be the non-limited view, to
6837 prevent spurious resolution errors.

6844 (Class_Wide_Clone): New attribute of subprogram. Designates
6845 subprogram created for primitive operations with class-wide
6846 pre/postconditions that contain calls to other primitives. The
6847 clone holds the body of the original primitive, but the
6848 pre/postonditions do not apply to it. The original body is
6849 rewritten as a wrapper for a call to the clone.
6850 (Is_Class_Wide_Clone): New flag to identify a Class_Wide_Clone. If
6851 the flag is set, no code for the corresponding pre/postconditions
6852 is inserted into its body.

7033 * types.ads, osint.adb, sinput-c.adb, sinput-d.adb, sinput-l.adb,
7034 * sinput-p.adb: Use regular fat pointers, with bounds checking,
7035 for source buffers. Fix misc obscure bugs.
7036 * sinput.ads, sinput.adb: Use regular fat pointers, with bounds
7037 checking, for source buffers. Modify representation clause for
7038 Source_File_Record as appropriate. Move Source_File_Index_Table
7039 from spec to body, because it is not used outside the body.
7040 Move Set_Source_File_Index_Table into the private part, because
7041 it is used only in the body and in children. Use trickery to
7042 modify the dope in the generic instantiation case. It's ugly,
7043 but not as ugly as the previous method. Fix documentation.
7044 Remove obsolete code.

7060 expander is not active or when index/range checks are suppressed
7062 (Insert_List_After_And_Analyze, Insert_List_Before_And_Analyze):
7063 Remove variants that include a Supress parameter. These routines
7064 are never used, and were introduced before the current scope-based

7117 the Internal_Source buffer. This removes the incorrect call to "="
7118 the customer noticed.
7119 Wrap remaining calls to "=" in Null_Source_Buffer_Ptr. We
7120 eventually need to eliminate them altogether. Or else get rid
7121 of zero-origin addressing.

7700 * a-numeri.ads: Change the encoding of Greek letter Pi from
7701 brackets encoding to UTF-8. Use pragma Wide_Character_Encoding
7702 to indicate the encoding. We considered using a byte order mark

7928 * sem_prag.adb (No_Return): Give an error if the pragma applies
7929 to a body. Specialize the error for the specless body case,
7930 as is done for (e.g.) pragma Convention.
7931 * debug.adb: Add switch -gnatd.J to disable the above legality
7932 checks. This is mainly for use in our test suite, to avoid
7933 rewriting a lot of illegal (but working) code. It might also
7934 be useful to customers. Under this switch, if a pragma No_Return
7935 applies to a body, and the procedure raises an exception (as it
7936 should), the pragma has no effect. If the procedure does return,
7937 execution is erroneous.
7939 2017-04-25 Bob Duff <duff@adacore.com>
7941 * exp_ch6.adb (Expand_Actuals): This is the
7942 root of the problem. It took N as an 'in out' parameter, and in
7943 some cases, rewrote N, but then set N to Original_Node(N). So
7944 the node returned in N had no Parent. The caller continued
7945 processing of this orphaned node. In some cases that caused a
7946 crash (e.g. Remove_Side_Effects climbs up Parents in a loop,
7947 and trips over the Empty Parent). The solution is to make N an
7948 'in' parameter. Instead of rewriting it, return the list of
7949 post-call actions, so the caller can do the rewriting later,
7950 after N has been fully processed.
7951 (Expand_Call_Helper): Move most of Expand_Call here. It has
7952 too many premature 'return' statements, and we want to do the
7953 rewriting on return.
7954 (Insert_Post_Call_Actions): New procedure to insert the post-call
7955 actions in the appropriate place. In the problematic case,
7956 that involves rewriting N as an Expression_With_Actions.
7957 (Expand_Call): Call the new procedures Expand_Call_Helper and
7958 Insert_Post_Call_Actions.
7960 2017-04-25 Ed Schonberg <schonberg@adacore.com>
7962 * sem_prag.adb (Inherits_Class_Wide_Pre): Cleanup code, handle
7963 properly type derived from generic formal types, to handle
7964 properly modified version of ACATS 4.1B B611017.
7966 2017-04-25 Javier Miranda <miranda@adacore.com>
7968 * exp_unst.adb (Subp_Index): Adding missing
7969 support for renamings and functions that return a constrained
7970 array type (i.e. functions for which the frontend built a
7971 procedure with an extra out parameter).
7973 2017-04-25 Pascal Obry <obry@adacore.com>
7975 * s-string.adb: Minor code clean-up.
7977 2017-04-25 Bob Duff <duff@adacore.com>

7982 function for Non_Blocking_Wait_Process.
7984 2017-04-25 Bob Duff <duff@adacore.com>
7986 * prep.adb (Preprocess): Remove incorrect
7987 Assert. Current character can be ASCII.CR.
7989 2017-04-25 Ed Schonberg <schonberg@adacore.com>
7991 * sem_prag.adb (Set_Convention_From_Pragma): Cleanup code for
7992 convention Stdcall, which has a number of exceptions. Convention
7993 is legal on a component declaration whose type is an anonymous
7994 access to subprogram.
7996 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
7998 * sem_ch4.adb: sem_ch4.adb Various reformattings.
7999 (Try_One_Prefix_Interpretation): Use the base type when dealing
8000 with a subtype created for purposes of constraining a private
8001 type with discriminants.
8003 2017-04-25 Javier Miranda <miranda@adacore.com>

8007 dispatching primitives (Restore_Warnings): Restore warning on
8008 late dispatching primitives (Save_Warnings): Save warning on late
8009 dispatching primitives (Do_Warning_Switch): Use -gnatw.j/-gnatw.J
8010 to enable/disable this warning.
8011 (WA_Warnings): Set warning on late dispatching primitives.
8012 * sem_ch3.adb (Analyze_Private_Extension_Declaration): Remember
8013 that its parent type has a private extension.
8014 * sem_disp.adb (Warn_On_Late_Primitive_After_Private_Extension):
8016 * usage.adb: Document -gnatw.j and -gnatw.J.
8018 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>

8023 2017-04-25 Bob Duff <duff@adacore.com>
8025 * binde.adb (Validate): Do not pass dynamic strings
8026 to pragma Assert, because older compilers do not support that.
8028 2017-04-25 Bob Duff <duff@adacore.com>
8030 * s-fileio.adb (Close): When a temp file is
8031 closed, delete it and clean up its Temp_File_Record immediately,
8032 rather than waiting until later.
8033 (Temp_File_Record): Add File
8034 component, so Close can know which Temp_File_Record corresponds
8035 to the file being closed.
8036 (Delete): Don't delete temp files,
8037 because they are deleted by Close.
8038 (Open): Set the File component
8039 of Temp_File_Record. This requires moving the creation of the
8040 Temp_File_Record to the end, after the AFCB has been created.
8042 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8044 * checks.adb (Insert_Valid_Check): Do not generate
8045 a validity check when inside a generic.
8047 2017-04-25 Yannick Moy <moy@adacore.com>
8049 * sem_res.adb (Resolve_Type_Conversion): Fix bad logic.
8051 2017-04-25 Arnaud Charlet <charlet@adacore.com>
8053 * snames.ads-tmpl (Snames): More names for detecting predefined

8059 concerning inheritance of class-wide preconditions do not apply
8062 2017-04-25 Bob Duff <duff@adacore.com>
8064 * s-ficobl.ads: Minor comment fix.
8066 2017-04-25 Yannick Moy <moy@adacore.com>
8068 * checks.adb (Apply_Scalar_Range_Check): Analyze precisely
8069 conversions from float to integer in GNATprove mode.
8070 (Apply_Type_Conversion_Checks): Make sure in GNATprove mode
8071 to call Apply_Type_Conversion_Checks, so that range checks
8072 are properly positioned when needed on conversions, including
8073 when converting from float to integer. (Determine_Range): In
8074 GNATprove mode, take into account the possibility of conversion
8075 from float to integer.
8076 * sem_res.adb (Resolve_Type_Conversion): Only enforce range
8077 check on conversions from fixed-point to integer, not anymore
8078 on conversions from floating-point to integer, when in GNATprove
8081 2017-04-25 Yannick Moy <moy@adacore.com>
8083 * checks.adb (Determine_Range_R): Special case type conversions
8084 from integer to float in order to get bounds in that case too.
8085 * eval_fat.adb (Machine): Avoid issuing warnings in GNATprove
8086 mode, for computations involved in interval checking.

8098 (Validated_Object): New routine along with pragma Inline.
8099 (Set_Validated_Object): New routine along with pragma Inline.
8100 * exp_attr.adb (Make_Range_Test): Add processing for validation
8101 variables to avoid extra reads and copies of the prefix.
8102 * exp_ch6.adb (Expand_Actuals): Add copy-back for validation
8103 variables in order to reflect any changes done in the variable
8104 back into the original object.
8105 * sem_util.adb (Is_Validation_Variable_Reference): New routine.
8106 * sem_util.ads (Is_Validation_Variable_Reference): New routine.

8112 generate Finalize_Address routines for CodePeer.
8114 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8116 * sem_prag.adb (Inherits_Class_Wide_Pre): subsidiary of
8117 Analyze_Pre_Post_Condition, to implement the legality checks
8118 mandated by AI12-0131: Pre'Class shall not be specified for an
8119 overriding primitive subprogram of a tagged type T unless the
8120 Pre'Class aspect is specified for the corresponding primitive
8121 subprogram of some ancestor of T.
8123 2017-04-25 Bob Duff <duff@adacore.com>
8125 * sem_ch8.adb (Use_One_Type): If a use_type_clause
8126 is redundant, set its Used_Operations to empty. This is only
8127 necessary for use clauses that appear in the parent of a generic
8128 child unit, because those use clauses get reanalyzed when we
8129 instantiate the generic, and we don't want the Used_Operations
8130 carried over from the original context (where it was probably
8133 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8135 * exp_ch6.adb: Minor reformatting.
8137 2017-04-25 Bob Duff <duff@adacore.com>
8139 * sem_prag.adb (Process_Restrictions_Or_Restriction_Warnings):

8142 (Current_Sem_Unit) to find the correct casing.
8143 * par.adb (Par): Null out Current_Source_File, to ensure that
8144 the above bugs won't rear their ugly heads again.
8146 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8148 * sem_ch8.adb (Find_Type): For an attribute reference
8149 'Class, if prefix type is synchronized and previous errors
8150 have suppressed the creation of the corresponding record type,
8151 create a spurious class-wide for the synchonized type itself,
8152 to catch other misuses of the attribute
8154 2017-04-25 Steve Baird <baird@adacore.com>
8156 * exp_ch6.adb (Expand_Simple_Function_Return): if CodePeer_Mode

8158 tag of a tagged result.
8159 * exp_intr.adb (Expand_Dispatching_Constructor_Call):
8160 if CodePeer_Mode is True, then don't generate the
8161 tag checks for the result of call to an instance of
8162 Ada.Tags.Generic_Dispatching_Constructor (i.e., both the "is a
8163 descendant of" check and the accessibility check).
8165 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8167 * sem_ch13.adb: Code cleanups.
8168 * a-strbou.ads: minor whitespace fix in Trim for bounded strings.

8173 * exp_ch4.adb (Library_Level_Target): New function.
8174 (Expand_Concatenate): When optimization is enabled, also expand
8175 the operation out-of-line if the concatenation is present within
8176 the expression of the declaration of a library-level object and
8177 not only if it is the expression of the declaration.
8179 2017-04-25 Bob Duff <duff@adacore.com>
8181 * freeze.adb (Freeze_Object_Declaration): Do
8182 not Remove_Side_Effects if there is a pragma Linker_Section,
8183 because in that case we want static initialization in the
8184 appropriate section.
8186 2017-04-25 Gary Dismukes <dismukes@adacore.com>
8188 * exp_dbug.adb: Minor rewording and reformatting.
8190 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8192 * sem_attr.adb (Statically_Denotes_Object): New predicate, to
8193 handle the proposed changes to rules concerning potentially
8194 unevaluated expressions, to include selected components that
8195 do not depend on discriminants, and indexed components with
8197 * sem_util.adb (Is_Potentially_Unevaluated): Add check for
8198 predicate in quantified expression, and fix bugs in the handling
8199 of case expressions and membership test.
8200 (Analyze_Attribute_Old_Result): use new predicate.
8201 (Analyze_Attribute, case Loop_Entry): ditto.
8203 2017-04-25 Bob Duff <duff@adacore.com>
8205 * s-secsta.adb (SS_Info): Add a comment
8206 explaining why we don't need to walk all the chunks in order to
8207 compute the total size.
8209 2017-04-25 Bob Duff <duff@adacore.com>
8211 * namet.ads, namet.adb (Global_Name_Buffer): Increase the length
8212 of the global name buffer to 4*Max_Line_Length.

8216 * exp_ch8.adb (Expand_N_Object_Renaming_Declaration): When creating a
8217 renaming entity for debug information, mark the entity as needing debug
8218 info if it comes from sources.
8220 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8222 * sem_ch13.adb (Analyze_Attribute_Definition_Clause): Remove the
8223 restriction converning the use of 'Address where the prefix is
8224 of a controlled type.
8226 2017-04-25 Pierre-Marie de Rodat <derodat@adacore.com>

8240 Preanalyze_Spec_Expression so that resolution takes place as well.
8241 * sem_util.adb (Check_Internal_Protected_Use): Reject properly
8242 internal calls that appear in preconditions of protected
8243 operations, in default values for same, and in contract guards
8244 for contract cases in SPARK.

8248 * a-numaux.ads: Fix description of a-numaux-darwin
8250 (Double): Define to Long_Float.
8251 * a-numaux-vxworks.ads (Double): Likewise.
8252 * a-numaux-darwin.ads
8254 * a-numaux-libc-x86.ads (Double): Define to Long_Long_Float.
8255 * a-numaux-x86.ads: Fix package description.
8256 * a-numaux-x86.adb (Is_Nan): Minor tweak.
8257 (Reduce): Adjust and complete description. Call Is_Nan instead of
8258 testing manually. Use an integer temporary to hold rounded value.
8259 * a-numaux-darwin.adb (Reduce): Likewise.
8260 (Is_Nan): New function.
8262 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8264 * sem_ch4.adb (Analyze_Selected_Component): Additional refinement
8265 on analysis of prefix whose type is a current instance of a
8266 synchronized type, but where the prefix itself is an entity that

8271 * exp_ch5.adb (Replace_Target): When rewriting the RHS, preserve
8272 the identity of callable entities therein, because they have been
8273 properly resolved, and prefixed calls may have been rewritten
8276 2017-04-25 Patrick Bernardi <bernardi@adacore.com>
8278 * exp_ch3.adb (Build_Init_Statements): Convert
8279 the expression of the pragma/aspect Secondary_Stack_Size to
8280 internal type System.Parameters.Size_Type before assigning
8281 it to the Secondary_Stack_Size component of the task type's
8282 corresponding record.

8286 * sem_eval.adb (Compile_Time_Compare): Reinstate the expr+literal
8287 (etc) optimizations when the type is modular and the offsets
8290 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
8292 * s-osinte-freebsd.ads: Minor comment tweaks
8294 2017-04-25 Javier Miranda <miranda@adacore.com>
8296 * urealp.adb (UR_Write): Reverse previous patch
8297 adding documentation on why we generate multiplications instead
8298 of divisions (needed to avoid expressions whose computation with
8299 large numbers may cause division by 0).
8301 2017-04-25 Bob Duff <duff@adacore.com>
8303 * erroutc.adb (Set_Specific_Warning_Off,
8304 Set_Warnings_Mode_Off): Use the correct source file for
8305 Stop. Was using Current_Source_File, which is only valid during
8306 parsing. Current_Source_File will have a leftover value from
8307 whatever file happened to be parsed last, because of a with_clause
8310 2017-04-25 Bob Duff <duff@adacore.com>
8312 * lib.ads, lib.adb (In_Internal_Unit): New functions similar
8313 to In_Predefined_Unit, but including GNAT units.
8314 * sem_util.ads, sem_util.adb (Should_Ignore_Pragma): Replace
8315 with Should_Ignore_Pragma_Par and Should_Ignore_Pragma_Sem,
8316 because Should_Ignore_Pragma was not working reliably outside
8317 the parser, because Current_Source_File is not valid.
8318 * sem_prag.adb, exp_prag.adb: Call Should_Ignore_Pragma_Sem.
8319 * par-prag.adb: Call Should_Ignore_Pragma_Par.

8388 * sem_ch4.adb (Analyze_Selected_Component): Refine analysis
8389 of prefix whose type is a current instance of a synchronized
8390 type. If the prefix is an object this is an external call (or
8391 requeue) that can only access public operations of the object. The
8392 previous predicate was too restrictive, and did not allow public
8393 protected operations, only task entries.
8395 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8397 * sem_ch5.adb, fname.adb: Minor reformatting.

8407 master for an access type subject to pragma No_Heap_Finalization.
8408 * exp_util.adb (Build_Allocate_Deallocate_Proc): An object being
8409 allocated or deallocated does not finalization actions if the
8410 associated access type is subject to pragma No_Heap_Finalization.
8411 * opt.ads Add new global variable No_Heap_Finalization_Pragma.
8412 * par-prag.adb Pragma No_Heap_Finalization does not need special
8413 processing from the parser.
8414 * sem_ch6.adb (Check_Return_Subtype_Indication): Remove ancient
8415 ??? comments. Use the new predicate Is_Anonymous_Access_Type.
8416 * sem_prag.adb Add an entry in table Sig_Flags for pragma
8417 No_Heap_Finalization.
8418 (Analyze_Pragma): Add processing for

8422 * snames.ads-tmpl: Add new predefined name No_Heap_Finalization
8423 and corresponding pragma id.

8427 * freeze.adb (Freeze_Record_Type): Use the
8428 underlying type of the component type to determine whether it's
8429 elementary. For representation clause purposes, a private type
8430 should behave the same as its full type.
8431 * fname.ads, fname.adb (Is_Predefined_File_Name):
8432 Make sure things like "system.ali" are recognized as predefined.
8434 2017-04-25 Javier Miranda <miranda@adacore.com>
8436 * debug.adb: Update documentation of -gnatd.6.
8438 2017-04-25 Ed Schonberg <schonberg@adacore.com>

8446 * uname.ads, uname.adb (Is_Predefined_Unit_Name,
8447 Is_Internal_Unit_Name): New functions for operating on unit
8448 names, as opposed to file names. There's some duplicated code
8449 with fname.adb, which is unfortunate, but it seems like we don't
8450 want to add dependencies here.
8451 * fname-uf.adb (Get_File_Name): Change Is_Predefined_File_Name
8452 to Is_Predefined_Unit_Name; the former was wrong, because Uname
8453 is not a file name at all.
8454 * fname.ads, fname.adb: Document the fact that
8455 Is_Predefined_File_Name and Is_Internal_File_Name can be called
8456 for ALI files, and fix the code so it works properly for ALI
8457 files. E.g. these should return True for "system.ali".
8459 2017-04-25 Justin Squirek <squirek@adacore.com>
8461 * exp_util.adb (Add_Invariant): Removed,
8462 code moved to Add_Invariant_Check, Add_Inherited_Invariant,

8471 and integrated code from Add_Parent_Invariants and
8472 Add_Interface_Invariants.
8473 (Process_Type): Removed, the

8501 (Replace_Type_References):
8502 Append an extra parameter to allow for dispatching replacements
8503 and add the corrasponding logic.

8514 when compiling predefined files.
8515 * fname.ads, fname.adb (Is_Predefined_File_Name): Fix bug:
8516 "gnat.adc" should not be considered a predefined file name.
8517 That required (or at least encouraged) a lot of cleanup of global
8518 variable usage. We shouldn't be communicating information via
8519 the global name buffer.
8520 * bindgen.adb, errout.adb, fname-uf.adb, lib-load.adb, make.adb,
8521 * restrict.adb, sem_ch10.adb, sem_ch6.adb, sem_ch8.adb: Changes

8581 the first pass over an assignment statement with target names,
8582 to prevent the generation of subtypes (such as discriminated

8600 For_Freeze. Add local variable Build_Body. Inherited DIC pragmas
8601 are now only processed when freezing occurs. Build a body only

8620 * sem_prag.adb (Analyze_Pragma): Guard against a case where a
8621 DIC pragma is placed at the top of a declarative region.
8623 2017-04-25 Arnaud Charlet <charlet@adacore.com trojanek>

8631 the error message when the attribute reference is an actual in
8632 a call to a subprogram inherited from a generic formal type with
8633 unknown discriminants, which makes the subprogram and its formal
8634 parameters intrinsic (see RM 6.3.1 (8) and (13)).
8636 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>

9391 to the expected type with the appropriate check flags set.
9392 * sem_res.adb (Resolve_Range): The higher bound can be in Typ's
9393 base type if the range is null. It may still be invalid if it

9413 in this case to compute reliably the size of the object, and
9414 eventually to raise Storage_Error, when wrap-around arithmetic
9415 might compute a meangingless size for the object.

9425 it is deciding whether to turn the call into an indexed
9426 component, avoid doing so if the call is to an instance of

9428 indexed component, and resolution of that turns it back into a
9429 function call, and so on, resulting in infinite recursion.
9430 * sem_util.adb (Needs_One_Actual): If the first formal has a

9946 * sem_ch8.adb (Find_Selected_Component): If the prefix might be
9947 interpreted as a parameterless function call and its analysis
9948 fails, do not call Analyze_Selected_Component.
9950 2017-01-19 Steve Baird <baird@adacore.com>
9952 * sem_util.ads: Add new Use_Full_View Boolean parameter to
9954 * sem_util.adb (Get_Index_Bounds): replace calls to Scalar_Range with
9955 calls to a newly-defined Scalar_Range_Of_Right_View function.
9957 2017-01-19 Arnaud Charlet <charlet@adacore.com>
9959 * gnat1drv.adb: minor fix of unbalanced parens in comment
9960 * lib-xref.ads (Traverse_Compilation_Unit): declaration moved
9961 to visible part of the package to allow re-use in GNATprove.
9962 * lib-xref-spark_specific.adb (Traverse_Stub): routine refactored
9963 from repeated code of Traverse_Compilation_Unit.
9964 (Traverse_Declaration_Or_Statement): fixed detection of
9965 generic subprograms and packages; also, iteration over case
9966 statement alternatives rewritten to avoid testing if the first
9967 alternative is present (since it must be present due to Ada
9968 syntax restrictions).
9970 2017-01-19 Hristian Kirtchev <kirtchev@adacore.com>
9972 * exp_ch6.adb (Expand_N_Subprogram_Body): Mark the spec as
9973 returning by reference not just for subprogram body stubs,
9974 but for all subprogram cases.
9975 * sem_util.adb: Code reformatting.
9976 (Requires_Transient_Scope): Update the call to Results_Differ.
9977 (Results_Differ): Update the parameter profile and the associated
9980 2017-01-19 Ed Schonberg <schonberg@adacore.com>
9982 * sem_dim.adb (Analyze_Dimension): Analyze object declaration and
9983 identifier nodes that do not come from source, to handle properly
9984 dimensionality check within an inlined body which inclddes both
9985 original operands and rewritten operands. This removes spurious
9986 dimensionality errors in the presence of front-end inlining,
9987 as well as in SPARK mode.
9989 2017-01-16 Jakub Jelinek <jakub@redhat.com>
9992 * gcc-interface/lang.opt (gant, gnatO, gnat): Add Driver flag.

10030 even if entity is already set, because the node may be renalyzed
10031 after inlining transformations.
10033 2017-01-13 Javier Miranda <miranda@adacore.com>
10035 * sem_res.adb (Resolve_Call): Do not establish a transient scope
10036 for a call to inlinable expression function (since the call will
10037 be replaced by its returned object).

10060 * sem_ch6.adb (Cloned_Expression): New subprogram.
10061 (Freeze_Expr_Types): Complete previous patch since the expression
10062 of an expression-function may have iterators and loops with
10063 defining identifiers which, as part of the preanalysis of the
10064 expression, may be left decorated with itypes that will not be
10065 available in the tree passed to the backend.
10067 2017-01-13 Ed Schonberg <schonberg@adacore.com>

10080 calls in accessibility check on return statement.
10082 2017-01-13 Hristian Kirtchev <kirtchev@adacore.com>
10084 * sem_ch6.adb (Analyze_Subprogram_Body_Helper):
10085 Ensure that the input body is a subprogram body before trying to
10086 determine whether it denoted an expression function. Note that
10087 subprogram body stubs cannot denote expression functions.
10089 2017-01-13 Gary Dismukes <dismukes@adacore.com>
10091 * bindgen.adb, sem_ch6.adb, binde.adb, exp_ch3.adb: Minor reformatting
10094 2017-01-13 Javier Miranda <miranda@adacore.com>
10096 * einfo.ads (Component_Bit_Offset): Fix documentation.
10097 * sem_ch13.adb (Check_Record_Representation_Clause): Skip check
10098 on record holes for components with unknown compile-time offsets.
10100 2017-01-13 Bob Duff <duff@adacore.com>
10102 * ali.ads, ali.adb (Static_Elaboration_Model_Used): Remove unused flag.
10103 * g-locfil.ads: Minor comment fix.
10105 2017-01-13 Bob Duff <duff@adacore.com>
10107 * binde.adb (Elab_New): New elaboration order algorithm
10108 that is expected to cause fewer ABE issues. This is a work in
10109 progress. The new algorithm is currently disabled, and can be
10110 enable by the -dp switch, or by modifying the Do_Old and Do_New
10111 etc. flags and rebuilding. Experimental code is included to
10112 compare the results of the old and new algorithms.
10113 * binde.ads: Use GNAT.Dynamic_Tables instead of Table, so we
10114 can have multiple of these tables, so the old and new algorithms
10116 * bindgen.ads (Gen_Output_File): Pass Elab_Order as an 'in'
10117 parameter of type array. This avoids the global variable, and
10118 allows bounds checking (which is normally defeated by the tables
10119 packages). It also ensures that the Elab_Order is read-only
10121 * bindgen.adb: Pass Elab_Order as an 'in' parameter to all
10122 subprograms that need it, as above.
10123 * debug.adb: Document new -dp switch. Modify doc of old -do
10125 * gnatbind.adb (Gnatbind): Make use of new interfaces to Binde
10126 and Bindgen. Move writing of closure (-R and -Ra switches)
10127 to Binde; that's more convenient.
10129 2017-01-13 Ed Schonberg <schonberg@adacore.com>
10131 * sem_ch6.adb (Analyze_Expression_Function): If the expression
10132 function is a completion, all entities referenced in the
10133 expression are frozen. As a consequence, a reference to an
10134 uncompleted private type from an enclosing scope is illegal.
10136 2017-01-13 Javier Miranda <miranda@adacore.com>
10138 * sem_ch6.adb (Freeze_Expr_Types): New subprogram.
10139 (Analyze_Subprogram_Body_Helper): At the occurrence of an
10140 expression function declaration that is a completion, its
10141 expression causes freezing (AI12-0103).
10143 2017-01-13 Vadim Godunko <godunko@adacore.com>
10145 * a-coinho-shared.adb: Fix memory leaks in Constant_Reference and

10152 2017-01-13 Hristian Kirtchev <kirtchev@adacore.com>
10154 * exp_ch3.adb (Default_Initialize_Object): Do not default
10155 initialize an object when it is of a task type and restriction
10156 No_Tasking is in effect because the initialization is obsolete.
10157 * exp_ch9.adb (Build_Master_Entity): Do not generate a master when
10158 restriction No_Tasking is in effect.
10159 (Build_Master_Renaming): Do not rename a master when restriction
10160 No_Tasking is in effect.
10162 2017-01-13 Ed Schonberg <schonberg@adacore.com>

10165 the legality of An others clause applies as well to a choice in
10166 an Iterated_component_ association.
10167 (Resolve_Iterated_Component_Association): An others choice
10169 * exp_aggr.adb (Aggr_Assignment_OK_For_Backend): An
10170 Iterated_Component_Association is not static.
10172 2017-01-13 Hristian Kirtchev <kirtchev@adacore.com>
10174 * exp_ch3.adb (Freeze_Type): Mark the Ghost mode as set in case
10175 control is passed to the expresion handler before the new mode

10178 Analyze_Subprogram_Instantiation): Mark the Ghost mode as set
10179 in case control is passed to the expresion handler before the

10185 exp_aggr.adb: Minor reformatting.
10187 2017-01-13 Gary Dismukes <dismukes@adacore.com>
10189 * inline.adb: Minor reformatting and typo fix.
10191 2017-01-13 Ed Schonberg <schonberg@adacore.com>
10193 * sem_util.ads, sem_util.adb (Choice_List): Move function here
10194 from sem_aggr.adb, for use elsewhere.
10195 * sem_ch3.adb (Analyze_Object_Declaration): Use Choice_List.
10196 * sem_aggr.adb (Resolve_Array_Aggregate): Remove
10197 Iterated_Component_Present.
10198 * exp_aggr.adb: Use Choice_List throughout, to handle
10199 Iterated_Component_Associations.
10200 (Gen_Loop): Generate proper loop for an
10201 Iterated_Component_Association: loop variable has the identifier
10202 of the original association. Generate a loop even for a single
10203 component choice, in order to make loop parameter visible in
10205 (Flatten): An Iterated_Component_Association is not static.
10207 2017-01-13 Yannick Moy <moy@adacore.com>
10209 * exp_ch4.adb (Expand_N_Op_Expon): Ensure that the value of
10210 float exponentiation for statically known small negative values
10211 is the reciprocal of the exponentiation for the opposite value
10213 * s-exnllf.adb (Exn_Float, Exn_Long_Float, Exn_Long_Long_Float):
10214 Ensure that the value of float exponentiation for negative values
10215 is the reciprocal of the exponentiation for the opposite value
10217 * inline.adb (Expand_Inlined_Call): Fix the count
10218 for the number of generated gotos.
10220 2017-01-13 Yannick Moy <moy@adacore.com>
10222 * inline.adb: Code cleanup.
10223 * sem_util.adb (Is_OK_Volatile_Context): Add
10224 expression in delay statement as OK for volatile context.
10226 2017-01-13 Ed Schonberg <schonberg@adacore.com>
10228 * sem_aggr.adb (Resolve_Array_Aggregate): In normal compilation
10229 mode a choice that is a subtype with a static predicate is
10230 replaced by the values it covers. This transformation must not
10231 be performed in ASIS mode, to preserve the source for analysis.
10233 2017-01-13 Justin Squirek <squirek@adacore.com>
10235 * nlists.ads: Correct minor typo.
10237 2017-01-13 Gary Dismukes <dismukes@adacore.com>

10244 Iterated_Component_Association is a named association in an
10246 * sem_aggr.adb (Resolve_Iterated_Component_Association): New
10247 procedure, subsidiary of Resolve_Array_Aggregate, to analyze
10248 and resolve the discrete choices and the expression of the
10250 * sinfo.adb, sinfo.ads: In analogy with N_Component_Association,
10251 Loop_Actions and Box_Present are attributes of
10252 N_Iterated_Component_Association nodes. Box_Present is always
10253 False in this case.
10254 * sprint.adb (Sprint_Node): An Iterated_Component_Association
10255 has a Discrete_Choices list, as specified in the RM. A
10256 Component_Association for aggregate uses instead a Choices list.
10257 We have to live with this small inconsistency because the new
10258 construct also has a defining identifier, and there is no way
10259 to merge the two node structures.
10261 2017-01-13 Yannick Moy <moy@adacore.com>
10263 * inline.adb (Remove_Aspects_And_Pragmas): Add Unused to the

10270 * sem_ch3.adb (Resolve_Aspects): New procedure, subsidiary of
10271 Analyze_Declarations, to analyze and resolve the expressions of
10272 aspect specifications in the current declarative list, so that
10273 the expressions have proper entity and type info. This is needed
10274 for ASIS when there is no subsequent expansion to generate this
10275 semantic information.
10276 * sem_ch13.adb (Check_Aspect_At_End_Of_Declarations): Use Etype of
10277 original expression, to suppress cascaded errors when expression
10278 has been constant-folded.
10279 (Resolve_Aspect_Expressions, Resolve_Name): Preserve entities in
10280 ASIS mode, because there is no subsequent expansion to decorate
10283 2017-01-13 Yannick Moy <moy@adacore.com>
10285 * inline.adb, inline.ads (Call_Can_Be_Inlined_In_GNATprove_Mode):
10286 New function to detect when a call may be inlined or not in
10288 (Expand_Inlined_Call): Ensure that a temporary
10289 is always created in the cases where a type conversion may be
10290 needed on an input parameter in GNATprove mode, so that GNATprove
10291 sees the check to perform.
10292 * sem_res.adb (Resolve_Call): In GNATprove mode, skip inlining
10293 when not applicable due to actual requiring type conversion
10294 with possible check but no temporary value can be copied for
10295 GNATprove to see the check.
