133 * freeze.adb (Freeze_Expression): Handle freeze of an entity defined
134 outside of a subprogram body. This case was previously handled during
135 preanalysis; the frozen entities were remembered and left pending until
136 we continued freezeing entities outside of the subprogram. Now, when
137 climbing the parents chain to locate the correct placement for the
138 freezeing node, we check if the entity can be frozen and only when no
139 enclosing node is marked as Must_Not_Freeze the entity is frozen.

145 (Analyze_Expression_Function, Process_Formals): Invoke
146 Preanalyze_Formal_Expression instead of Preanalyze_Spec_Expression
147 since the analysis of the formals may freeze entities.

149 class-wide clone for eliminated subprograms.
150 * sem_res.ads, sem_res.adb (Preanalyze_And_Resolve): New subprogram.
151 Its code is basically the previous version of this routine but extended
152 with an additional parameter which is used to specify if during
153 preanalysis we are allowed to freeze entities. If the new parameter is
154 True then the subtree root node is marked as Must_Not_Freeze and no
155 entities are frozen during preanalysis.
156 (Preanalyze_And_Resolve): Invokes the internal version of
157 Preanalyze_And_Resolve without entity freezing.
158 (Preanalyze_With_Freezing_And_Resolve): Invokes the internal version of
159 Prenalyze_And_Resolve with freezing enabled.

193 enclosing scope already handles the secondary stack, take into account
194 transient blocks nested in a block that do not manage the secondary
195 stack and are located within a loop.
197 2018-07-17 Ed Schonberg <schonberg@adacore.com>
199 * sem_util.adb (Enclosing_Subprogram): Protected entries and task
200 entries must be treated separately: task entries are within the

1070 2018-05-31 Ed Schonberg <schonberg@adacore.com>
1072 * exp_unst.ads, exp_unst.adb (In_Synchronized_Unit): New predicate to
1073 mark subprograms that cannot be eliminated because they must be treated
1074 as reachable from outside the current unit. This includes entry bodies
1075 and protected operations.
1077 2018-05-31 Ed Schonberg <schonberg@adacore.com>
1079 * exp_ch4.adb (Expand_Modular_Addition, Expand_Modular_Subtraction):
1080 Convert all operands of the generated code to Standard.Unsigned, to
1081 prevent spurious visibility errors. This is needed when the generated
1082 expansion involves a modular index type of an array type, and the index
1083 type is not immediately visible.

1092 * exp_ch11.adb (Replace_Raise_By_Goto): The transfomation is legal even
1093 if the local raise statement includes a string expression. This
1094 expression might be picked up by an outer handler or discarded, but
1095 plays no role in this transformation.

1109 * exp_unst.adb (Visit_Node): Do not traverse a Component_Association
1110 that has not been analyzed, as will be the case for a nested aggregate
1111 that is expanded into individual assignments.

1120 set it to use the same processing as Pragma_Max_Queue_Length.
1121 * snames.ads-tmpl: Move definition of Name_Max_Entry_Queue_Depth so
1122 that it can be processed as a pragma in addition to a restriction and
1123 add an entry for the pragma itself.
1125 2018-05-30 Ed Schonberg <schonberg@adacore.com>
1127 * freeze.adb (Freeze_Object_Declaration): A pragma Thread_Local_Storage
1128 is now legal on a variable of composite type initialized with an
1129 aggregate that is fully static and requires no elaboration code.
1130 * exp_aggr.adb (Convert_To_Positional): Recognize additional cases of
1131 nested aggregates that are compile-time static, so they can be used to
1132 initialize variables declared with Threqd_Local_Storage.

1146 (Start_Search): Modify to use Start_Search_Internal
1147 (Start_Search_Internal): Add to break out an extra flag for searching
1148 case insensative due to the potential for directories within the same
1149 OS to allow different casing schemes.
1150 * sysdep.c (__gnat_name_case_equivalence): Add as a default fallback
1151 for when the more precise solution fails.

1209 * sem_ch3.adb (Access_Subprogram_Declaration): The flag
1210 Needs_Activation_Record is only needed on a subprogram type, not on a
1212 * sem_res.adb (Resolve_Selected_Component): If the context type and the
1213 component type are anonymous access to subprograms, use the component
1214 type to obtain the proper value of Needs_Activation_Record flag for the

1220 comment about the memset case.
1222 2018-05-30 Bob Duff <duff@adacore.com>
1224 * exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove the code
1225 to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
1226 We need to analyze it as part of analyzing the block, so that if the
1227 call to Element that initializes Elmt_Decl returns on the secondary
1228 stack, the block will ss_mark/ss_release. This block is inside the
1229 loop; we don't want to leak memory until the loop exits. The purpose
1230 of analyzing Elmt_Decl first was to catch the error of modifying it,
1231 which is illegal because it's a loop parameter. The above causes us to
1232 miss that error. Therefore, we add a flag Is_Loop_Parameter, and set
1233 it on the Element entity, so we end up with an E_Variable node with the
1235 * einfo.ads, einfo.adb (Is_Loop_Parameter): New flag.
1236 * sem_ch5.adb (Diagnose_Non_Variable_Lhs): Give the "assignment to loop
1237 parameter not allowed" error if Is_Loop_Parameter.
1238 * sem_util.adb (Is_Variable): Return False if Is_Loop_Parameter, to
1239 trigger the call to Diagnose_Non_Variable_Lhs.
1241 2018-05-30 Arnaud Charlet <charlet@adacore.com>
1243 * checks.adb (Apply_Scalar_Range_Check):
1244 * sem_eval.adb (Check_Non_Static_Context, Out_Of_Range): Ignore out of
1245 range values for System.Priority in CodePeer mode since the actual
1246 target compiler may provide a wider range.
1248 2018-05-30 Ed Schonberg <schonberg@adacore.com>
1250 * exp_unst.adb: Search specification of main unit as well, for
1253 2018-05-30 Ed Schonberg <schonberg@adacore.com>
1255 * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of
1256 a package body that is a compilation unit may contain blocks that
1257 declare local subprograms. In Subprogram_Unnesting Mode such
1258 subprograms must be handled as nested inside the (implicit) elaboration
1259 procedure that executes that statement part. To handle properly uplevel
1260 references we construct that subprogram explicitly, to contain blocks
1261 and inner subprograms, The statement part of the compilation unit
1262 becomes a call to this subprogram. This is only done if blocks are
1263 present in the statement list of the body.
1265 2018-05-30 Bob Duff <duff@adacore.com>
1267 * exp_ch7.adb: Minor comment fix.

1273 corresponding wrapper package declaration.
1274 (Register_Subprogram): New subprogram, used for subprogram bodies and
1275 for subprogram instantiations to enter callable entity into Subp table.

1279 * libgnat/s-secsta.adb: Reimplement the secondary stack support.
1280 * libgnat/s-secsta.ads: Update the documentation of all routines in the
1281 public part of the package. Reimplement the private part of the
1282 package to account for the new secondary stack structure. Add types
1283 and subprograms for testing purposes. Add several documentation

1328 untagged private types completed with a derivation of an untagged
1329 private whose full view is a tagged type.

1332 (Collect_Primitive_Operations): Handle untagged private types completed
1333 with a derivation of an untagged private type whose full view is a
1334 tagged type. In such case, collecting the list of primitives we may
1335 find two equality primitives: one associated with the untagged private
1336 and another associated with the ultimate tagged type (and we must
1337 remove from the returned list this latter one).

1567 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1569 * exp_unst.adb (Visit_Node): For indexed components and attribute
1570 references, examine index expressions or associated expressions as well
1571 to record uplevel references.
1572 (Vist_Node): For function and procedure calls, if a formal is an
1573 unconstrained array and the actual is constrained, check whether bounds
1574 of actual have uplevel references.
1576 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1578 * einfo.ads, einfo.adb: Exceptions can be uplevel references, and thus
1579 they can appear as components of activation records.
1580 * exp_unst.adb (Visit_Node): A reference to an exception may be an

1585 * exp_ch4.adb (Expand_Composite_Equality): Compute whether the size
1586 depends on a discriminant manually instead of using the predicate
1587 Size_Depends_On_Discriminant in the array type case.
1589 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1591 * exp_unst.adb (Check_Static_Type): For a record subtype, check
1592 discriminant constraints as well.
1593 (Visit_Node): For a selected component, check type of prefix, as is
1594 done for indexed components and slices.
1596 2018-05-28 Javier Miranda <miranda@adacore.com>
1598 * exp_ch4.adb (Real_Range_Check): Add a temporary to store the integer
1599 value when converting a float value to a fixed-point value. This is
1600 required for CCG because it handles fixed-point types by means of
1601 unsigned integer type variables. The range check is now performed using
1602 the integer value stored in this temporary.
1604 2018-05-28 Yannick Moy <moy@adacore.com>
1606 * sem_util.adb (Is_OK_Volatile_Context): Add attributes First, Last and

1616 Is_Overriding_Subprogram, generic in Find_Dispatching_Type function.
1617 (Inherited_Subprograms): Instance of Generic_Inherited_Subprograms with
1618 Sem_Disp.Find_Dispatching_Type.
1619 (Is_Overriding_Subprogram): Instance of
1620 Generic_Is_Overriding_Subprogram with Sem_Disp.Find_Dispatching_Type.
1621 (Inheritance_Utilities_Inst): Instance of Inheritance_Utilities
1622 with Sem_Disp.Find_Dispatching_Type.
1624 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
1626 * exp_ch4.adb (Expand_Composite_Equality): For a composite (or FP)
1627 component type, do not expand array equality using the unconstrained
1628 base type, except for the case where the bounds of the type depend on a
1631 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1633 * einfo.ads, einfo.adb (Needs_Activation_Record): New flag on
1634 access-to-subprogram types, to indicate that an indirect call through
1635 such a type requires an activation record when compiling for LLVM.
1636 * sem_ch3.adb (Access_Subprogram_Declaration): Set new flag as needed.
1638 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1640 * exp_ch4.adb (Real_Range_Check): Specialize float-to-fixed conversions
1641 when bounds of fixed type are static, to remove some spuerfluous
1642 implicit conversions and provide an accurate result when converting
1643 back and forth between the fixed point type and a floating point type.
1645 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1647 * exp_unst.adb (Unnest_Subprogram): Prevent creation of empty
1650 2018-05-28 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
1652 * exp_unst.adb (Check_Static_Type): Add argument to indicate node to be
1653 replaced, if any; all callers changed.
1654 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
1655 constant with private view so we take the address of that entity.
1656 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
1657 any; all callers changed. Handle N_Indexed_Component like
1658 N_Attribute_Reference. Add N_Type_Conversion case.
1659 (Visit_Node): Indexed references can be uplevel if the type isn't
1661 (Unnest_Subprograms): Don't rewrite if no reference given. If call has
1662 been relocated, set first_named pointer in original node as well.
1664 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1666 * exp_aggr.adb (Flatten): Copy tree of expression in a component
1667 association with a range or a set of discrete choices, rather than
1668 relocating the node. This avoids inconsistencies in the tree when
1669 handling nested subprograms with uplevel references for LLVM.
1671 2018-05-28 Arnaud Charlet <charlet@adacore.com>
1673 * exp_util.adb (Possible_Bit_Aligned_Component): Always return False in

1682 * libgnat/a-convec.adb (Query_Element): Minor cleanup: remove an
1683 unnecessary use of 'Unrestricted_Access.
1685 2018-05-28 Hristian Kirtchev <kirtchev@adacore.com>
1687 * repinfo.adb (Expr_Value_S): New routine.
1688 (List_Linker_Section): Properly extract the value of the section
1691 2018-05-28 Patrick Bernardi <bernardi@adacore.com>
1693 * doc/gnat_ugn/building_executable_programs_with_gnat.rst: Update the
1694 description of the -D binder switch to reflect current usage.
1695 * gnat_ugn.texi: Regenerate.
1697 2018-05-28 Gary Dismukes <dismukes@adacore.com>

1722 2018-05-28 Hristian Kirtchev <kirtchev@adacore.com>
1724 * sem_prag.adb (Process_Atomic_Independent_Shared_Volatile): Include
1725 the declarations of single concurrent types because they fall in the
1726 category of full type and object declarations.
1728 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
1730 * repinfo.adb (Compute_Max_Length): Skip _Parent component.

1733 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1735 * sem_util.adb (Is_Function_Result): Add a warning if a postcondition
1736 includes a call to function to which it applies. This may mean an
1737 omission of an attribute reference 'Result, in particular if the
1738 function is pqrameterless.
1740 2018-05-28 Justin Squirek <squirek@adacore.com>
1742 * sem_ch8.adb (Find_Expanded_Name): Add extra guard to make sure the

1747 * sem_res.adb (Resolve_Range): Re-resolve the low bound of a range in
1748 GNATprove mode, as the order of resolution (low then high) means that

1752 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
1754 * repinfo.adb (List_Array_Info): Start with an explicit blank line and
1755 end with the linker section, if any.
1756 (List_Entities): Do not output the linker section for record types,
1757 array types and variables.
1758 (Print_Expr): Factor out common processing for unary operators and
1759 special values. Adjust and reorder the various cases.
1760 (List_Object_Info): End with the linker section, if any.
1761 (List_Record_Info): Likewise.
1762 (List_Type_Info): Do not start with a blank line.
1764 2018-05-25 Nicolas Roche <roche@adacore.com>
1766 * libgnat/s-valrea.adb (Scan_Real): Abort computation once it is sure
1767 that the result will be either -infinite or +infinite.
1769 2018-05-25 Patrick Bernardi <bernardi@adacore.com>
1771 * libgnat/s-parame.ads, libgnat/s-parame__vxworks.ads,

1773 Expand range of type to match the address space of the target.
1774 (Task_Storage_Size): Remove unused type.
1776 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1778 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
1779 of a fixed point type and the parent is a multiplying operation,
1780 resolve the operand with its own type because the context will impose a
1781 resulting type on the result of the multiplication by means of
1782 approriate conversion.
1784 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1786 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
1787 the in-place initialization aggregate created for pragmas
1788 Initialize_Scalars or Normalize_Scalars is performed with checks
1791 2018-05-25 Arnaud Charlet <charlet@adacore.com>
1793 * exp_aggr.adb (Convert_To_Positional): Bump default for
1794 Max_Others_Replicate to 32. Update comments.
1795 * osint.ads (Unknown_Attributes): No longer pretend this is a constant.
1796 (No_File_Info_Cache): Initialize separately.

1807 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1809 * exp_aggr.adb (Flatten): A quantified expression cannot be duplicated
1810 in an others clause to prevent visibility issues with the generated

1815 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1817 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
1818 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
1819 into three distring cases rather than in one loop which attempts to
1820 handle all three cases. This rewrite eliminates an issue where the last
1821 frame of the stack cannot be freed, thus causing the memory range of a
1822 new frame to approach the overflow point of the memory index type.
1823 Since the overflow is logically treated as a
1824 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
1825 (SS_Allocate_Static): New routine. The routine factorizes the static
1826 secondary stack-related code from the former SS_Allocate.
1828 2018-05-25 Sergey Rybin <rybin@adacore.com>
1830 * doc/gnat_ugn/gnat_and_program_execution.rst: Add description of '-U'
1831 option for gnatelim.
1833 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1835 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create
1836 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
1837 is created when the proper body of the stub is analyzed.
1838 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
1839 is the proper body of a subunit, the cloned body must be inserted in
1840 the declarative list that contains the stub.
1842 2018-05-25 Justin Squirek <squirek@adacore.com>
1844 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
1845 generate code for 6.5(8-10) so that we don't get an assertion error
1846 when dealing with an incomplete return type.
1848 2018-05-25 Arnaud Charlet <charlet@adacore.com>
1850 * pprint.adb (Expression_Name): Strip too long expressions to avoid
1851 carrying very large strings.

1877 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1879 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
1880 Validate_Derived_Type_Instance, to verify that all interfaces
1881 implemented by the formal type are also implemented by the actual. The
1882 verification is complicated when an interface of the formal is declared
1883 in a generic unit and the actual is declared in an instance of it.
1884 There is currently no mechanism to relate an interface declared within
1885 a generic to the corresponding interface in an instance, so we must
1886 traverse the list of interfaces of the actual, looking for a name
1887 match, and verifying that that interface is declared in an instance.
1889 2018-05-25 Piotr Trojanek <trojanek@adacore.com>
1891 * sem_util.adb (Iterate_Call_Parameters): Rewrite with extra
1892 assertions; replace function versions of Next_Formal/Next_Actual with
1893 their procedural versions (which are more concise).

1927 boolean type with convention C.
1928 * libgnat/i-cexten.ads (bool): Change to boolean with convention C.
1929 * gcc-interface/decl.c (gnat_to_gnu_entity): Add new local variable
1930 FOREIGN and use it throughout the function.
1931 <E_Enumeration_Type>: Set precision 1 on boolean types with foreign

1934 <E_Record_Type>: Force the size of a storage unit on empty classes.
1935 * gcc-interface/utils.c (make_type_from_size) <BOOLEAN_TYPE>: Skip
1936 boolean types with precision 1 if the size is the expected one.

1954 prefixes of array attributes, to prefixes that are entity names whose
1955 type is constrained.
1956 (Note_Uplevel_Bound): Verify that the bound is declared in an enclosing
1957 subprogram, as itype created for loops in pre/postcondition may appear
1958 in loops at the library level.
1960 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1962 * sem_ch13.adb (Build_Predicate_Functions): The predicate function
1963 declaration is inserted into the tree and analyzed at that point, so
1964 should not be reinserted when the body is constructed. Inside a
1965 generic, ensure that the body is not inserted twice in the tree.

2000 2018-05-24 Javier Miranda <miranda@adacore.com>

3036 * sem_util.adb (Find_Simple_Properties): New routine.
3037 (Is_Enabled_External_Property): New routine.
3038 (State_Has_Enabled_Property): Reimplemented. The two flavors of option
3039 External have precedence over option Synchronous when determining
3040 whether a property is in effect.

3060 Address, and type of Low, High to Storage_Offset.
3061 (Low): Rename as Low_Address and convey that the return value is a
3062 runtime reference accounting for a load address.
3063 * libgnat/s-dwalin.adb (Read_Aranges_Entry): Adjust to the
3064 address/offset type changes.
3065 (Aranges_Lookup): Likewise.

3090 lm.l_addr as the Load_Address to Add_Module_To_Cache.
3092 2018-05-21 Piotr Trojanek <trojanek@adacore.com>
3094 * einfo.adb (Has_Discriminants): Stronger assertion.

3119 formal private type.
3121 2018-05-21 Hristian Kirtchev <kirtchev@adacore.com>
3123 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
3124 delegate the secondary stack management when there is no suitable
3125 transient context, and the transient scope was intended to manage the
3126 secondary stack because this causes premature reclamation. Change the
3127 transient scope creation logic by special casing assignment statements
3128 of controlled components for type initialization procedures.
3129 (Find_Node_To_Be_Wrapped): Renamed to Find_Transient_Context. Update
3130 the comment on usage.
3131 (Find_Transient_Context): Change the initinte loop into a while loop.

3133 contexts because they rely on special processing. Assignment statements
3134 are now treated as a normal transient context, special cases are
3135 handled by the caller. Add special processing for pragma Check.
3136 (Is_OK_Construct): Removed. Its functionality has been merged in
3137 routine Find_Transient_Context.
3138 * sem_ch5.adb (Check_Call): Reimplemented. Add code to properly
3139 retrieve the subprogram being invoked. Use a more accurate predicate
3140 (Requires_Transient_Scope) to determine that the function will emply
3141 the secondary stack.

3343 suitable construct to wrap, and the transient scope was intended to
3344 manage the secondary stack.
3345 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
3346 is a valid boundary for a transient expression which comes from the
3347 statements of the alternative, otherwise alternatives cannot be
3348 wrapped. Assignments of controlled objects which have controlled
3349 actions suppressed now stop the traversal as there is no point in
3350 looking for an enclosing construct. Add several N_xxx_Body choices to
3351 the termination conditions for completeness.

3359 actions are required by utilizing predicate Needs_Finalization rather
3361 (Resolve_Call): Type initialization procedures can now utilize
3362 transient scopes to manage the secondary stack, thus preventing leaks
3363 during initialization. Remove the previous kludgy algorithm which
3364 attempts to manage the secondary stack at the object creation site.

3412 in the generic unless they reference a formal subprogram. Clarify

3540 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3542 * sem_util.adb (Find_Enclosing_Scope): Return the unique defining
3543 entity when the enclosing construct is a body.
3545 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
3547 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
3548 Secondary_Stack_Size handling as a pragma is now generated for the
3549 corresponding aspect instead of an attribute. Pragma expression is
3550 relocated instead of evaluated. Discriminant of the corresponding
3551 record type is referenced rather than the type discriminant.
3552 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
3553 Secondary_Stack_Size rep item checks to only look for the pragma rep.
3554 * sem_ch13.adb (Analyze_One_Aspect): Transform
3555 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
3556 because the attribute does not have visibility on a task type's
3557 discriminants when the type's definition is expanded.
3558 (Analyze_Attribute_Definition_Clause): Remove handling of
3559 Attribute_Secondary_Stack_Size.
3560 * snames.adb-tmpl, snames.ads-tmpl: Remove
3561 Attribute_Secondary_Stack_Size, no longer used.

3565 * sem_ch8.adb: Minor comment fix.
3567 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3569 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
3570 individual action because the action may denote a complex expression,
3571 such as a case statement, which in turn may contain additional
3574 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3576 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
3577 analysis on a copy of the expression with a copy of the index variable,
3578 because full expansion will rewrite construct into a loop with the
3579 original loop variable.
3580 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
3581 expression is an iterated component association. Full analysis takes
3582 place when construct is rewritten as a loop.
3583 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
3584 is not safe for in-place assignment.
3585 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
3586 entity with no homonym and no other entity in the scope.
3588 2018-01-11 Justin Squirek <squirek@adacore.com>
3590 * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
3591 message to be printed on the pragma argument identifier.
3593 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3595 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
3596 entity of the generated invariant procedure in order to construct a
3597 proper entity chain.
3599 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
3601 * sem_ch13.adb (Build_Predicate_Functions): Fix minor issues in
3604 2018-01-11 Arnaud Charlet <charlet@adacore.com>
3606 * einfo.ads, einfo.adb (Activation_Record_Component,
3607 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
3608 Allow E_Discriminant.
3610 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
3612 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
3613 for atomic access once the component size is taken into account and
3614 also do it if the component type is Atomic or Volatile_Full_Access.
3616 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
3618 * gnatvsn.ads: Bump copyright year.
