207 * sem_ch4.adb (Try_Object_Operation): Handle properly a prefixed call
208 in an instance, when the generic parameters include an interface type
209 and a abstract operation of that type, and the actuals in the instance
210 include an interface type and a corresponding abstract operation of it,

373 outside of a subprogram body. This case was previously handled during

375 we continued freezeing entities outside of the subprogram. Now, when
376 climbing the parents chain to locate the correct placement for the
377 freezeing node, we check if the entity can be frozen and only when no

381 * sem_ch3.adb (Preanalyze_Default_Expression): Code adjusted to invoke
382 the new subprogram Preanalyze_With_Freezing_And_Resolve.

384 (Analyze_Expression_Function, Process_Formals): Invoke
385 Preanalyze_Formal_Expression instead of Preanalyze_Spec_Expression

389 * sem_res.ads, sem_res.adb (Preanalyze_And_Resolve): New subprogram.
390 Its code is basically the previous version of this routine but extended
391 with an additional parameter which is used to specify if during
392 preanalysis we are allowed to freeze entities. If the new parameter is
393 True then the subtree root node is marked as Must_Not_Freeze and no
394 entities are frozen during preanalysis.
395 (Preanalyze_And_Resolve): Invokes the internal version of
396 Preanalyze_And_Resolve without entity freezing.
397 (Preanalyze_With_Freezing_And_Resolve): Invokes the internal version of
398 Prenalyze_And_Resolve with freezing enabled.

432 enclosing scope already handles the secondary stack, take into account
433 transient blocks nested in a block that do not manage the secondary
434 stack and are located within a loop.
436 2018-07-17 Ed Schonberg <schonberg@adacore.com>
438 * sem_util.adb (Enclosing_Subprogram): Protected entries and task
439 entries must be treated separately: task entries are within the
440 enclosing subprogram of the task type, while protected entries are
441 transformed into the corresponding Protected_Body_Subprogram, which is

1318 * exp_ch4.adb (Expand_Modular_Addition, Expand_Modular_Subtraction):
1319 Convert all operands of the generated code to Standard.Unsigned, to
1320 prevent spurious visibility errors. This is needed when the generated

1461 2018-05-30 Bob Duff <duff@adacore.com>
1463 * exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove the code
1464 to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
1465 We need to analyze it as part of analyzing the block, so that if the
1466 call to Element that initializes Elmt_Decl returns on the secondary
1467 stack, the block will ss_mark/ss_release. This block is inside the
1468 loop; we don't want to leak memory until the loop exits. The purpose
1469 of analyzing Elmt_Decl first was to catch the error of modifying it,
1470 which is illegal because it's a loop parameter. The above causes us to
1471 miss that error. Therefore, we add a flag Is_Loop_Parameter, and set
1472 it on the Element entity, so we end up with an E_Variable node with the
1474 * einfo.ads, einfo.adb (Is_Loop_Parameter): New flag.
1475 * sem_ch5.adb (Diagnose_Non_Variable_Lhs): Give the "assignment to loop
1476 parameter not allowed" error if Is_Loop_Parameter.
1477 * sem_util.adb (Is_Variable): Return False if Is_Loop_Parameter, to

1492 2018-05-30 Ed Schonberg <schonberg@adacore.com>
1494 * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of
1495 a package body that is a compilation unit may contain blocks that
1496 declare local subprograms. In Subprogram_Unnesting Mode such
1497 subprograms must be handled as nested inside the (implicit) elaboration
1498 procedure that executes that statement part. To handle properly uplevel
1499 references we construct that subprogram explicitly, to contain blocks
1500 and inner subprograms, The statement part of the compilation unit
1501 becomes a call to this subprogram. This is only done if blocks are
1502 present in the statement list of the body.

1573 tagged type. In such case, collecting the list of primitives we may
1574 find two equality primitives: one associated with the untagged private
1575 and another associated with the ultimate tagged type (and we must
1576 remove from the returned list this latter one).

1589 * exp_ch6.adb (Expand_N_Subprogram_Body): Do not generate push/pop for
1590 exceptions if subprogram unnesting is in effect, because these branch
1591 nodes are relevant only in the presence of nested subprograms.

1595 * libgnat/s-fatgen.adb (Succ, Pred): Raise Constraint_Error
1596 unconditionally when applied to the largest positive (resp. largest
1597 negative) value of a floating-point type.

1613 carry no type. Such selected components appear in unit names that are
1614 child units, both in the specification and possibly in an end label for
1615 the unit, and they do not contain any relevant uplevel references.

1806 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1808 * exp_unst.adb (Visit_Node): For indexed components and attribute
1809 references, examine index expressions or associated expressions as well
1810 to record uplevel references.
1811 (Vist_Node): For function and procedure calls, if a formal is an
1812 unconstrained array and the actual is constrained, check whether bounds
1813 of actual have uplevel references.
1815 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1817 * einfo.ads, einfo.adb: Exceptions can be uplevel references, and thus
1818 they can appear as components of activation records.

1825 depends on a discriminant manually instead of using the predicate
1826 Size_Depends_On_Discriminant in the array type case.
1828 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1830 * exp_unst.adb (Check_Static_Type): For a record subtype, check
1831 discriminant constraints as well.
1832 (Visit_Node): For a selected component, check type of prefix, as is
1833 done for indexed components and slices.
1835 2018-05-28 Javier Miranda <miranda@adacore.com>
1837 * exp_ch4.adb (Real_Range_Check): Add a temporary to store the integer
1838 value when converting a float value to a fixed-point value. This is
1839 required for CCG because it handles fixed-point types by means of
1840 unsigned integer type variables. The range check is now performed using
1841 the integer value stored in this temporary.
1843 2018-05-28 Yannick Moy <moy@adacore.com>
1845 * sem_util.adb (Is_OK_Volatile_Context): Add attributes First, Last and

1865 * exp_ch4.adb (Expand_Composite_Equality): For a composite (or FP)
1866 component type, do not expand array equality using the unconstrained
1867 base type, except for the case where the bounds of the type depend on a
1870 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1872 * einfo.ads, einfo.adb (Needs_Activation_Record): New flag on
1873 access-to-subprogram types, to indicate that an indirect call through
1874 such a type requires an activation record when compiling for LLVM.
1875 * sem_ch3.adb (Access_Subprogram_Declaration): Set new flag as needed.
1877 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1879 * exp_ch4.adb (Real_Range_Check): Specialize float-to-fixed conversions
1880 when bounds of fixed type are static, to remove some spuerfluous
1881 implicit conversions and provide an accurate result when converting
1882 back and forth between the fixed point type and a floating point type.
1884 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1886 * exp_unst.adb (Unnest_Subprogram): Prevent creation of empty
1889 2018-05-28 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
1891 * exp_unst.adb (Check_Static_Type): Add argument to indicate node to be
1892 replaced, if any; all callers changed.
1893 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
1894 constant with private view so we take the address of that entity.
1895 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
1896 any; all callers changed. Handle N_Indexed_Component like
1897 N_Attribute_Reference. Add N_Type_Conversion case.
1898 (Visit_Node): Indexed references can be uplevel if the type isn't
1900 (Unnest_Subprograms): Don't rewrite if no reference given. If call has
1901 been relocated, set first_named pointer in original node as well.
1903 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1905 * exp_aggr.adb (Flatten): Copy tree of expression in a component
1906 association with a range or a set of discrete choices, rather than
1907 relocating the node. This avoids inconsistencies in the tree when
1908 handling nested subprograms with uplevel references for LLVM.

1963 * sem_prag.adb (Process_Atomic_Independent_Shared_Volatile): Include
1964 the declarations of single concurrent types because they fall in the
1965 category of full type and object declarations.

1972 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1974 * sem_util.adb (Is_Function_Result): Add a warning if a postcondition
1975 includes a call to function to which it applies. This may mean an
1976 omission of an attribute reference 'Result, in particular if the
1977 function is pqrameterless.
1979 2018-05-28 Justin Squirek <squirek@adacore.com>

1986 * sem_res.adb (Resolve_Range): Re-resolve the low bound of a range in
1987 GNATprove mode, as the order of resolution (low then high) means that

1993 * repinfo.adb (List_Array_Info): Start with an explicit blank line and
1994 end with the linker section, if any.
1995 (List_Entities): Do not output the linker section for record types,
1996 array types and variables.
1997 (Print_Expr): Factor out common processing for unary operators and
1998 special values. Adjust and reorder the various cases.
1999 (List_Object_Info): End with the linker section, if any.
2000 (List_Record_Info): Likewise.
2001 (List_Type_Info): Do not start with a blank line.
2003 2018-05-25 Nicolas Roche <roche@adacore.com>
2005 * libgnat/s-valrea.adb (Scan_Real): Abort computation once it is sure
2006 that the result will be either -infinite or +infinite.
2008 2018-05-25 Patrick Bernardi <bernardi@adacore.com>
2010 * libgnat/s-parame.ads, libgnat/s-parame__vxworks.ads,
2011 libgnat/s-parame__ae653.ads, libgnat/s-parame__hpux.ads (Size_Type):
2012 Expand range of type to match the address space of the target.
2013 (Task_Storage_Size): Remove unused type.
2015 2018-05-25 Ed Schonberg <schonberg@adacore.com>
2017 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
2018 of a fixed point type and the parent is a multiplying operation,
2019 resolve the operand with its own type because the context will impose a
2020 resulting type on the result of the multiplication by means of
2021 approriate conversion.
2023 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
2025 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
2026 the in-place initialization aggregate created for pragmas
2027 Initialize_Scalars or Normalize_Scalars is performed with checks
2030 2018-05-25 Arnaud Charlet <charlet@adacore.com>
2032 * exp_aggr.adb (Convert_To_Positional): Bump default for
2033 Max_Others_Replicate to 32. Update comments.
2034 * osint.ads (Unknown_Attributes): No longer pretend this is a constant.
2035 (No_File_Info_Cache): Initialize separately.

2054 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
2056 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
2057 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
2058 into three distring cases rather than in one loop which attempts to
2059 handle all three cases. This rewrite eliminates an issue where the last
2060 frame of the stack cannot be freed, thus causing the memory range of a
2061 new frame to approach the overflow point of the memory index type.
2062 Since the overflow is logically treated as a
2063 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
2064 (SS_Allocate_Static): New routine. The routine factorizes the static
2065 secondary stack-related code from the former SS_Allocate.
2067 2018-05-25 Sergey Rybin <rybin@adacore.com>
2069 * doc/gnat_ugn/gnat_and_program_execution.rst: Add description of '-U'

2118 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
2119 Validate_Derived_Type_Instance, to verify that all interfaces
2120 implemented by the formal type are also implemented by the actual. The

2122 in a generic unit and the actual is declared in an instance of it.
2123 There is currently no mechanism to relate an interface declared within
2124 a generic to the corresponding interface in an instance, so we must
2125 traverse the list of interfaces of the actual, looking for a name
2126 match, and verifying that that interface is declared in an instance.

2572 a constrained array component.
2573 * einfo.adb: Subprograms for Predicated_Parent.
2574 (Predicate_Function): Use new attribute.
2575 * exp_util.adb (Make_Predicate_Call): If the predicate function is not

2695 * sem_ch5.adb (Preanalyze_Range): The pre-analysis of the domain of
2696 iteration of an Ada2012 loop is performed to determine the type of the
2697 domain, but full analysis is performed once the loop is rewritten as a

2699 must also suppress the generation of freeze nodes, which may otherwise
2700 appear in the wrong scope before rewritting.

3545 * binde.adb, par-ch6.adb, par-ch9.adb, sem_ch12.adb, sem_ch13.adb:
3548 2018-01-11 Justin Squirek <squirek@adacore.com>
3550 * par-ch6.adb (Scan_Body_Or_Expression_Function): Add additional check
3551 to make sure a given expression function is properly parenthesized.
3553 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3555 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Check the
3556 categorization of a subprogram body which does not complete a previous
3559 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3561 * sem_ch10.adb (Check_Private_Child_Unit): Ensure that the enclosing
3562 scope of package Ada is Standard.
3564 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3566 * sem_ch13.adb (Replace_Type_Ref): Handle properly reference to a
3567 subcomponent of the current entity when building the body for a dynamic
3568 predicate function for a record with composite subcomponents.
3570 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3572 * exp_aggr.adb (Convert_Aggr_In_Object_Decl): Update the call to
3573 Establish_Transient_Scope.
3574 (Convert_To_Assignments): Update the call to Establish_Transient_Scope.
3575 (Expand_Array_Aggregate): Update the call to Establish_Transient_Scope.
3576 * exp_ch6.adb (Expand_Call_Helper): Update the call to
3577 Establish_Transient_Scope.
3578 (Make_Build_In_Place_Call_In_Object_Declaration): Update the call to
3579 Establish_Transient_Scope.
3580 * exp_ch7.adb (Establish_Transient_Scope): Restructured. Delegate the
3581 management of the secondary stack to an enclosing scope if there is no
3582 suitable construct to wrap, and the transient scope was intended to
3583 manage the secondary stack.
3584 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
3585 is a valid boundary for a transient expression which comes from the
3586 statements of the alternative, otherwise alternatives cannot be
3587 wrapped. Assignments of controlled objects which have controlled
3588 actions suppressed now stop the traversal as there is no point in
3589 looking for an enclosing construct. Add several N_xxx_Body choices to
3590 the termination conditions for completeness.
3591 * exp_ch7.ads (Establish_Transient_Scope): Update the parameter profile
3592 and the associated comment on usage.
3593 * exp_smem.adb (Add_Shared_Var_Lock_Procs): Update the call to
3594 Establish_Transient_Scope.
3595 (Add_Write_After): Update the call to Establish_Transient_Scope.
3596 * sem_res.adb (Check_Initialization_Call): Removed.
3597 (Resolve_Actuals): Account for additional cases where finalization
3598 actions are required by utilizing predicate Needs_Finalization rather
3600 (Resolve_Call): Type initialization procedures can now utilize
3601 transient scopes to manage the secondary stack, thus preventing leaks
3602 during initialization. Remove the previous kludgy algorithm which
3603 attempts to manage the secondary stack at the object creation site.
3605 2018-01-11 Jerome Lambourg <lambourg@adacore.com>
3607 * libgnat/g-soliop__qnx.ads: New.
3608 * adaint.c, adaint.h, cstreams.c, s-oscons-tmplt.c, sysdep.c: Update

3614 a null procedure occurs in a protected definition.
3616 2018-01-11 Bob Duff <duff@adacore.com>
3618 * binderr.ads, namet.ads: Minor reformatting.

3638 * doc/Makefile: Add Sphinx option -W to treat warnings as errors.
3640 2018-01-11 Ben Brosgol <brosgol@adacore.com>
3642 * doc/gnat_rm/implementation_defined_aspects.rst: Minor type/wording
3644 * gnat_rm.texi: Regenerate.
3646 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3648 * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the
3649 formsl type corresponding to the actual fixed point type is private,
3650 because in this case there can be no suspicious arithmetic operations
3651 in the generic unless they reference a formal subprogram. Clarify
3654 2018-01-11 Javier Miranda <miranda@adacore.com>
3656 * exp_util.adb (Remove_Side_Effects): No action done for functions
3657 returning class-wide types since it requires generating code using
3658 'reference and the CCG target has no secondary stack.
3659 * gnat1drv.adb: Disable building static dispatch tables when generating
3662 2018-01-11 Piotr Trojanek <trojanek@adacore.com>

3665 libgnat/a-textio.ads, libgnat/a-witeio.ads, libgnat/a-ztexio.ads
3666 (File_Type): Add Default_Initial_Condition aspect.
3668 2018-01-11 Pascal Obry <obry@adacore.com>
3670 * libgnat/s-os_lib.adb (Normalize_Pathname): New implementation.
3672 2018-01-11 Bob Duff <duff@adacore.com>
3674 * doc/gnat_ugn/gnat_utility_programs.rst: Rewrite gnatpp documentation
3675 to match what the Libadalang-based version does.
3676 * doc/gnat_ugn/about_this_guide.rst: Update reference.
3678 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3680 * sem_res.adb (Uses_SS): A controlled type requires the secondary stack
3681 if it contains at least one component declaration employing a function
3682 call returning on the secondary stack.
3684 2018-01-11 Yannick Moy <moy@adacore.com>
3686 * doc/gnat_rm/standard_and_implementation_defined_restrictions.rst:
3687 Update description of restriction SPARK_05 with SPARK 2014.

3697 sem_res.adb, sem_util.adb: Minor reformatting.
3699 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3701 * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
3702 has a delayed aspect which must be processed at the point the type is
3703 frozen. This mimics what is done when the predicate is provided by a
3706 2018-01-11 Doug Rupp <rupp@adacore.com>
3708 * init.c (vxworks): Add macro checks for __aarch64__.
3710 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3712 * exp_util.adb (Add_Failure_Expression): New routine.
3713 (Make_Predicate_Check): Reimplement the handling of Predicate_Failure.
3714 * sem_util.adb (Is_Current_Instance): Code cleanup.
3716 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
3718 * libgnat/s-parame*.adb, libgnat/s-parame*.ads: Remove unneeded
3719 Default_Sec_Stack_Size.
3720 * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
3721 limit check so that the integer index does not overflow. Check the
3722 dynamic stack allocation does not cause the secondary stack pointer to
3724 (SS_Info): Align colons.
3725 (SS_Init): Cover the case when bootstraping with an old compiler that
3726 does not set Default_SS_Size.
3728 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3730 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
3731 legality of an inherited operation that may require overriding, ignore
3732 primitive_wrappers that correspond to explicit operations that override
3733 an interface primitive.
3734 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
3735 operation to which the class-wide expression applies is a protected op.
3736 with a primitive_wrapper, verify that the updated inherited expression
3737 does not contain an internal call to a protected function. This
3738 completes the implementation of AI12-0166.
3740 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3742 * ali.adb: Document the remaining letters available for ALI lines.
3743 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
3744 * ali.ads: Update type With_Record. Field
3745 Implicit_With_From_Instantiation is no longer in use. Add field
3747 * csinfo.adb (CSinfo): Remove the setup for attribute
3748 Implicit_With_From_Instantiation.
3749 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
3750 either implicitly or explicitly withed.
3751 (Is_Implicit_With_Clause): New routine.
3752 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
3753 confusion with the with clause attribute by the same name.
3754 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
3755 * rtsfind.adb (Maybe_Add_With): Code cleanup.
3756 * sem_ch8.adb (Present_System_Aux): Code cleanup.
3757 * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
3759 (Implicit_With_On_Parent): Mark the with clause as generated for a
3761 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
3762 instantiation are no longer marked as Implicit_With_From_Instantiation
3763 because they are already marked as implicit.
3764 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
3765 which marks implicit with clauses as related to an instantiation.
3766 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
3767 (Parent_With): New routine.
3768 (Set_Implicit_With_From_Instantiation): Removed.
3769 (Set_Parent_With): New routine.
3770 * sinfo.ads: Update the documentation of attribute Implicit_With.
3771 Remove attribute Implicit_With_From_Instantiation along with
3772 occurrences in nodes. Add attribute Parent_With along with occurrences
3774 (Implicit_With_From_Instantiation): Removed along with pragma Inline.
3775 (Parent_With): New routine along with pragma Inline.
3776 (Set_Implicit_With_From_Instantiation): Removed along with pragma Inline.
3777 (Set_Parent_With): New routine along with pragma Inline.
3779 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3781 * sem_util.adb (Find_Enclosing_Scope): Return the unique defining
3782 entity when the enclosing construct is a body.
3784 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
3786 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
3787 Secondary_Stack_Size handling as a pragma is now generated for the
3788 corresponding aspect instead of an attribute. Pragma expression is
3789 relocated instead of evaluated. Discriminant of the corresponding
3790 record type is referenced rather than the type discriminant.
3791 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
3792 Secondary_Stack_Size rep item checks to only look for the pragma rep.
3793 * sem_ch13.adb (Analyze_One_Aspect): Transform
3794 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
3795 because the attribute does not have visibility on a task type's
3796 discriminants when the type's definition is expanded.
3797 (Analyze_Attribute_Definition_Clause): Remove handling of
3798 Attribute_Secondary_Stack_Size.
3799 * snames.adb-tmpl, snames.ads-tmpl: Remove
3800 Attribute_Secondary_Stack_Size, no longer used.
3802 2018-01-11 Justin Squirek <squirek@adacore.com>
3804 * sem_ch8.adb: Minor comment fix.
3806 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3808 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
3809 individual action because the action may denote a complex expression,
3810 such as a case statement, which in turn may contain additional
3813 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3815 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
3816 analysis on a copy of the expression with a copy of the index variable,
3817 because full expansion will rewrite construct into a loop with the
3818 original loop variable.
3819 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
3820 expression is an iterated component association. Full analysis takes
3821 place when construct is rewritten as a loop.
3822 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
3823 is not safe for in-place assignment.
3824 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
3825 entity with no homonym and no other entity in the scope.
3827 2018-01-11 Justin Squirek <squirek@adacore.com>
3829 * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
3830 message to be printed on the pragma argument identifier.
3832 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3834 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
3835 entity of the generated invariant procedure in order to construct a
3836 proper entity chain.
3838 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
3840 * sem_ch13.adb (Build_Predicate_Functions): Fix minor issues in
3843 2018-01-11 Arnaud Charlet <charlet@adacore.com>
3845 * einfo.ads, einfo.adb (Activation_Record_Component,
3846 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
3847 Allow E_Discriminant.
3849 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
3851 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
3852 for atomic access once the component size is taken into account and
3853 also do it if the component type is Atomic or Volatile_Full_Access.
3855 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
3857 * gnatvsn.ads: Bump copyright year.

3860 Alan Hayward <alan.hayward@arm.com>
3861 David Sherwood <david.sherwood@arm.com>

3874 Alan Hayward <alan.hayward@arm.com>
3875 David Sherwood <david.sherwood@arm.com>
3877 * gcc-interface/utils.c (gnat_types_compatible_p): Handle
3878 polynomial TYPE_VECTOR_SUBPARTS.
3880 2018-01-03 Richard Sandiford <richard.sandiford@linaro.org>
3881 Alan Hayward <alan.hayward@arm.com>
3882 David Sherwood <david.sherwood@arm.com>

3887 2018-01-03 Jakub Jelinek <jakub@redhat.com>
3889 Update copyright years.
3891 * gnat_ugn.texi: Bump @copying's copyright year.
3892 * gnat_rm.texi: Likewise.
