Fix an existing incorrect test for 501 renaming of a discriminant-dependent component of a untagged 502 generic formal type being within a generic body, adding test of 503 taggedness and calling In_Generic_Body (now properly checks for 504 cases where the renaming is in a nongeneric body nested within a 505 generic). Return False in cases where the selector is not a 506 component (or discriminant), which can occur for 507 prefixed-notation calls. 508 5092018-12-03 Ed Schonberg <schonberg@adacore.com> 510 511 * sem_res.adb (Apply_Check): For array types, apply a length 512 check rather than a qualification, to avoid spurious errors when 513 the value of a dependend expression has a matching length but 514 different bounds from those of the type of the contect. 515 5162018-12-03 Hristian Kirtchev <kirtchev@adacore.com> 517 518 * libgnat/a-calend.adb: Update the number of leap seconds.

This block is inside the 3285 loop; we don't want to leak memory until the loop exits. The purpose 3286 of analyzing Elmt_Decl first was to catch the error of modifying it, 3287 which is illegal because it's a loop parameter. The above causes us to 3288 miss that error. Therefore, we add a flag Is_Loop_Parameter, and set 3289 it on the Element entity, so we end up with an E_Variable node with the 3290 flag set. 3291 * einfo.ads, einfo.adb (Is_Loop_Parameter): New flag. 3292 * sem_ch5.adb (Diagnose_Non_Variable_Lhs): Give the "assignment to loop 3293 parameter not allowed" error if Is_Loop_Parameter. 3294 * sem_util.adb (Is_Variable): Return False if Is_Loop_Parameter, to 3295 trigger the call to Diagnose_Non_Variable_Lhs. 3296 32972018-05-30 Arnaud Charlet <charlet@adacore.com> 3298 3299 * checks.adb (Apply_Scalar_Range_Check): 3300 * sem_eval.adb (Check_Non_Static_Context, Out_Of_Range): Ignore out of 3301 range values for System.Priority in CodePeer mode since the actual 3302 target compiler may provide a wider range. 3303 33042018-05-30 Ed Schonberg <schonberg@adacore.com> 3305 3306 * exp_unst.adb: Search specification of main unit as well, for 3307 unnesting. 3308 33092018-05-30 Ed Schonberg <schonberg@adacore.com> 3310 3311 * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of 3312 a package body that is a compilation unit may contain blocks that 3313 declare local subprograms.

To handle properly uplevel 3316 references we construct that subprogram explicitly, to contain blocks 3317 and inner subprograms, The statement part of the compilation unit 3318 becomes a call to this subprogram.

Pragma expression is 5606 relocated instead of evaluated. Discriminant of the corresponding 5607 record type is referenced rather than the type discriminant. 5608 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update 5609 Secondary_Stack_Size rep item checks to only look for the pragma rep. 5610 * sem_ch13.adb (Analyze_One_Aspect): Transform 5611 Aspect_Secondary_Stack_Size into a pragma instead of an attribute 5612 because the attribute does not have visibility on a task type's 5613 discriminants when the type's definition is expanded. 5614 (Analyze_Attribute_Definition_Clause): Remove handling of 5615 Attribute_Secondary_Stack_Size. 5616 * snames.adb-tmpl, snames.ads-tmpl: Remove 5617 Attribute_Secondary_Stack_Size, no longer used. 5618 56192018-01-11 Justin Squirek <squirek@adacore.com> 5620 5621 * sem_ch8.adb: Minor comment fix. 5622 56232018-01-11 Hristian Kirtchev <kirtchev@adacore.com> 5624 5625 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an 5626 individual action because the action may denote a complex expression, 5627 such as a case statement, which in turn may contain additional 5628 transient objects. 5629 56302018-01-11 Ed Schonberg <schonberg@adacore.com> 5631 5632 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform 5633 analysis on a copy of the expression with a copy of the index variable, 5634 because full expansion will rewrite construct into a loop with the 5635 original loop variable. 5636 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the 5637 expression is an iterated component association. Full analysis takes 5638 place when construct is rewritten as a loop. 5639 (In_Place_Assign_OK, Safe_Component): An iterated_component_association 5640 is not safe for in-place assignment. 5641 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated 5642 entity with no homonym and no other entity in the scope. 5643 56442018-01-11 Justin Squirek <squirek@adacore.com> 5645 5646 * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error 5647 message to be printed on the pragma argument identifier. 5648 56492018-01-11 Hristian Kirtchev <kirtchev@adacore.com> 5650 5651 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last 5652 entity of the generated invariant procedure in order to construct a 5653 proper entity chain. 5654 56552018-01-11 Piotr Trojanek <trojanek@adacore.com> 5656 5657 * sem_ch13.adb (Build_Predicate_Functions): Fix minor issues in 5658 comment. 5659 56602018-01-11 Arnaud Charlet <charlet@adacore.com> 5661 5662 * einfo.ads, einfo.adb (Activation_Record_Component, 5663 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity): 5664 Allow E_Discriminant. 5665 56662018-01-10 Eric Botcazou <ebotcazou@adacore.com> 5667 5668 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check 5669 for atomic access once the component size is taken into account and 5670 also do it if the component type is Atomic or Volatile_Full_Access. 5671 56722018-01-04 Eric Botcazou <ebotcazou@adacore.com> 5673 5674 * gnatvsn.ads: Bump copyright year. 5675 56762018-01-03 Richard Sandiford <richard.sandiford@linaro.org> 5677 Alan Hayward <alan.hayward@arm.com> 5678 David Sherwood <david.sherwood@arm.com> 5679 5680 * gcc-interface/misc.c (enumerate_modes): Treat GET_MODE_BITSIZE 5681 as polynomial. 5682 56832018-01-03 Richard Sandiford <richard.sandiford@linaro.org> 5684 Alan Hayward <alan.hayward@arm.com> 5685 David Sherwood <david.sherwood@arm.com> 5686 5687 * gcc-interface/misc.c (enumerate_modes): Treat GET_MODE_PRECISION 5688 as polynomial. 5689 56902018-01-03 Richard Sandiford <richard.sandiford@linaro.org> 5691 Alan Hayward <alan.hayward@arm.com> 5692 David Sherwood <david.sherwood@arm.com> 5693 5694 * gcc-interface/utils.c (gnat_types_compatible_p): Handle 5695 polynomial TYPE_VECTOR_SUBPARTS. 5696 56972018-01-03 Richard Sandiford <richard.sandiford@linaro.org> 5698 Alan Hayward <alan.hayward@arm.com> 5699 David Sherwood <david.sherwood@arm.com> 5700 5701 * gcc-interface/misc.c (enumerate_modes): Handle polynomial 5702 GET_MODE_NUNITS. 5703 57042018-01-03 Jakub Jelinek <jakub@redhat.com> 5705 5706 Update copyright years. 5707 5708 * gnat_ugn.texi: Bump @copying's copyright year. 5709 * gnat_rm.texi: Likewise. 5710 5711Copyright (C) 2018 Free Software Foundation, Inc. 5712 5713Copying and distribution of this file, with or without modification, 5714are permitted in any medium without royalty provided the copyright 5715notice and this notice are preserved. 5716
