182 * exp_ch13.adb (Expand_N_Freeze_Entity): Handle subtype declared for an
184 * freeze.adb (Freeze_Expression): Handle freeze of an entity defined
185 outside of a subprogram body. This case was previously handled during
186 preanalysis; the frozen entities were remembered and left pending until
187 we continued freezeing entities outside of the subprogram. Now, when
188 climbing the parents chain to locate the correct placement for the
189 freezeing node, we check if the entity can be frozen and only when no
190 enclosing node is marked as Must_Not_Freeze the entity is frozen.

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

196 (Analyze_Expression_Function, Process_Formals): Invoke
197 Preanalyze_Formal_Expression instead of Preanalyze_Spec_Expression
198 since the analysis of the formals may freeze entities.

200 class-wide clone for eliminated subprograms.
201 * sem_res.ads, sem_res.adb (Preanalyze_And_Resolve): New subprogram.
202 Its code is basically the previous version of this routine but extended
203 with an additional parameter which is used to specify if during
204 preanalysis we are allowed to freeze entities. If the new parameter is
205 True then the subtree root node is marked as Must_Not_Freeze and no
206 entities are frozen during preanalysis.
207 (Preanalyze_And_Resolve): Invokes the internal version of
208 Preanalyze_And_Resolve without entity freezing.
209 (Preanalyze_With_Freezing_And_Resolve): Invokes the internal version of
210 Prenalyze_And_Resolve with freezing enabled.

244 enclosing scope already handles the secondary stack, take into account
245 transient blocks nested in a block that do not manage the secondary
246 stack and are located within a loop.
248 2018-07-17 Ed Schonberg <schonberg@adacore.com>
250 * sem_util.adb (Enclosing_Subprogram): Protected entries and task
251 entries must be treated separately: task entries are within the

1125 as reachable from outside the current unit. This includes entry bodies
1126 and protected operations.
1128 2018-05-31 Ed Schonberg <schonberg@adacore.com>
1130 * exp_ch4.adb (Expand_Modular_Addition, Expand_Modular_Subtraction):
1131 Convert all operands of the generated code to Standard.Unsigned, to
1132 prevent spurious visibility errors. This is needed when the generated
1133 expansion involves a modular index type of an array type, and the index
1134 type is not immediately visible.

1197 (Start_Search): Modify to use Start_Search_Internal
1198 (Start_Search_Internal): Add to break out an extra flag for searching

1271 comment about the memset case.
1273 2018-05-30 Bob Duff <duff@adacore.com>
1275 * exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove the code
1276 to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
1277 We need to analyze it as part of analyzing the block, so that if the
1278 call to Element that initializes Elmt_Decl returns on the secondary
1279 stack, the block will ss_mark/ss_release. This block is inside the
1280 loop; we don't want to leak memory until the loop exits. The purpose
1281 of analyzing Elmt_Decl first was to catch the error of modifying it,
1282 which is illegal because it's a loop parameter. The above causes us to
1283 miss that error. Therefore, we add a flag Is_Loop_Parameter, and set
1284 it on the Element entity, so we end up with an E_Variable node with the
1286 * einfo.ads, einfo.adb (Is_Loop_Parameter): New flag.
1287 * sem_ch5.adb (Diagnose_Non_Variable_Lhs): Give the "assignment to loop
1288 parameter not allowed" error if Is_Loop_Parameter.
1289 * sem_util.adb (Is_Variable): Return False if Is_Loop_Parameter, to
1290 trigger the call to Diagnose_Non_Variable_Lhs.

1295 * sem_eval.adb (Check_Non_Static_Context, Out_Of_Range): Ignore out of
1296 range values for System.Priority in CodePeer mode since the actual
1297 target compiler may provide a wider range.

1301 * exp_unst.adb: Search specification of main unit as well, for
1304 2018-05-30 Ed Schonberg <schonberg@adacore.com>
1306 * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of
1307 a package body that is a compilation unit may contain blocks that
1308 declare local subprograms. In Subprogram_Unnesting Mode such
1309 subprograms must be handled as nested inside the (implicit) elaboration
1310 procedure that executes that statement part. To handle properly uplevel
1311 references we construct that subprogram explicitly, to contain blocks
1312 and inner subprograms, The statement part of the compilation unit
1313 becomes a call to this subprogram. This is only done if blocks are
1314 present in the statement list of the body.
1316 2018-05-30 Bob Duff <duff@adacore.com>

1326 for subprogram instantiations to enter callable entity into Subp table.

1333 package to account for the new secondary stack structure. Add types
1334 and subprograms for testing purposes. Add several documentation

1384 with a derivation of an untagged private type whose full view is a
1385 tagged type. In such case, collecting the list of primitives we may
1386 find two equality primitives: one associated with the untagged private

1587 * lib-writ.adb (Write_ALI): Cleanup: avoid use of global var; call new
1589 * libgnat/s-casuti.ads, libgnat/s-casuti.adb (To_Upper, To_Lower,
1590 To_Mixed): New functions.
1591 * osint.adb: Cleanup: use Is_Directory_Separator, which correctly
1592 allows both '\' and '/' on Windows.

1620 * exp_unst.adb (Visit_Node): For indexed components and attribute
1621 references, examine index expressions or associated expressions as well
1622 to record uplevel references.
1623 (Vist_Node): For function and procedure calls, if a formal is an
1624 unconstrained array and the actual is constrained, check whether bounds
1625 of actual have uplevel references.
1627 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1629 * einfo.ads, einfo.adb: Exceptions can be uplevel references, and thus
1630 they can appear as components of activation records.

1636 * exp_ch4.adb (Expand_Composite_Equality): Compute whether the size
1637 depends on a discriminant manually instead of using the predicate
1638 Size_Depends_On_Discriminant in the array type case.
1640 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1642 * exp_unst.adb (Check_Static_Type): For a record subtype, check
1643 discriminant constraints as well.
1644 (Visit_Node): For a selected component, check type of prefix, as is
1645 done for indexed components and slices.
1647 2018-05-28 Javier Miranda <miranda@adacore.com>
1649 * exp_ch4.adb (Real_Range_Check): Add a temporary to store the integer
1650 value when converting a float value to a fixed-point value. This is
1651 required for CCG because it handles fixed-point types by means of
1652 unsigned integer type variables. The range check is now performed using
1653 the integer value stored in this temporary.
1655 2018-05-28 Yannick Moy <moy@adacore.com>
1657 * sem_util.adb (Is_OK_Volatile_Context): Add attributes First, Last and

1668 (Inherited_Subprograms): Instance of Generic_Inherited_Subprograms with
1669 Sem_Disp.Find_Dispatching_Type.
1670 (Is_Overriding_Subprogram): Instance of
1671 Generic_Is_Overriding_Subprogram with Sem_Disp.Find_Dispatching_Type.

1673 with Sem_Disp.Find_Dispatching_Type.
1675 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
1677 * exp_ch4.adb (Expand_Composite_Equality): For a composite (or FP)
1678 component type, do not expand array equality using the unconstrained
1679 base type, except for the case where the bounds of the type depend on a
1682 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1684 * einfo.ads, einfo.adb (Needs_Activation_Record): New flag on
1685 access-to-subprogram types, to indicate that an indirect call through
1686 such a type requires an activation record when compiling for LLVM.
1687 * sem_ch3.adb (Access_Subprogram_Declaration): Set new flag as needed.
1689 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1691 * exp_ch4.adb (Real_Range_Check): Specialize float-to-fixed conversions
1692 when bounds of fixed type are static, to remove some spuerfluous
1693 implicit conversions and provide an accurate result when converting
1694 back and forth between the fixed point type and a floating point type.
1696 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1698 * exp_unst.adb (Unnest_Subprogram): Prevent creation of empty
1701 2018-05-28 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
1703 * exp_unst.adb (Check_Static_Type): Add argument to indicate node to be
1704 replaced, if any; all callers changed.
1705 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
1706 constant with private view so we take the address of that entity.
1707 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
1708 any; all callers changed. Handle N_Indexed_Component like
1709 N_Attribute_Reference. Add N_Type_Conversion case.
1710 (Visit_Node): Indexed references can be uplevel if the type isn't
1712 (Unnest_Subprograms): Don't rewrite if no reference given. If call has
1713 been relocated, set first_named pointer in original node as well.
1715 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1717 * exp_aggr.adb (Flatten): Copy tree of expression in a component
1718 association with a range or a set of discrete choices, rather than
1719 relocating the node. This avoids inconsistencies in the tree when
1720 handling nested subprograms with uplevel references for LLVM.

1724 * exp_util.adb (Possible_Bit_Aligned_Component): Always return False in

1733 * libgnat/a-convec.adb (Query_Element): Minor cleanup: remove an
1734 unnecessary use of 'Unrestricted_Access.
1736 2018-05-28 Hristian Kirtchev <kirtchev@adacore.com>
1738 * repinfo.adb (Expr_Value_S): New routine.
1739 (List_Linker_Section): Properly extract the value of the section
1742 2018-05-28 Patrick Bernardi <bernardi@adacore.com>
1744 * doc/gnat_ugn/building_executable_programs_with_gnat.rst: Update the
1745 description of the -D binder switch to reflect current usage.
1746 * gnat_ugn.texi: Regenerate.
1748 2018-05-28 Gary Dismukes <dismukes@adacore.com>

1773 2018-05-28 Hristian Kirtchev <kirtchev@adacore.com>
1775 * sem_prag.adb (Process_Atomic_Independent_Shared_Volatile): Include
1776 the declarations of single concurrent types because they fall in the
1777 category of full type and object declarations.
1779 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
1781 * repinfo.adb (Compute_Max_Length): Skip _Parent component.

1784 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1786 * sem_util.adb (Is_Function_Result): Add a warning if a postcondition
1787 includes a call to function to which it applies. This may mean an
1788 omission of an attribute reference 'Result, in particular if the
1789 function is pqrameterless.
1791 2018-05-28 Justin Squirek <squirek@adacore.com>

1798 * sem_res.adb (Resolve_Range): Re-resolve the low bound of a range in
1799 GNATprove mode, as the order of resolution (low then high) means that
1800 all the information is not available when resolving the low bound the
1803 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
1805 * repinfo.adb (List_Array_Info): Start with an explicit blank line and
1806 end with the linker section, if any.
1807 (List_Entities): Do not output the linker section for record types,
1808 array types and variables.
1809 (Print_Expr): Factor out common processing for unary operators and
1810 special values. Adjust and reorder the various cases.
1811 (List_Object_Info): End with the linker section, if any.
1812 (List_Record_Info): Likewise.
1813 (List_Type_Info): Do not start with a blank line.
1815 2018-05-25 Nicolas Roche <roche@adacore.com>
1817 * libgnat/s-valrea.adb (Scan_Real): Abort computation once it is sure
1818 that the result will be either -infinite or +infinite.
1820 2018-05-25 Patrick Bernardi <bernardi@adacore.com>
1822 * libgnat/s-parame.ads, libgnat/s-parame__vxworks.ads,
1823 libgnat/s-parame__ae653.ads, libgnat/s-parame__hpux.ads (Size_Type):
1824 Expand range of type to match the address space of the target.
1825 (Task_Storage_Size): Remove unused type.
1827 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1829 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
1830 of a fixed point type and the parent is a multiplying operation,
1831 resolve the operand with its own type because the context will impose a
1832 resulting type on the result of the multiplication by means of
1833 approriate conversion.
1835 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1837 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
1838 the in-place initialization aggregate created for pragmas
1839 Initialize_Scalars or Normalize_Scalars is performed with checks
1842 2018-05-25 Arnaud Charlet <charlet@adacore.com>
1844 * exp_aggr.adb (Convert_To_Positional): Bump default for
1845 Max_Others_Replicate to 32. Update comments.
1846 * osint.ads (Unknown_Attributes): No longer pretend this is a constant.
1847 (No_File_Info_Cache): Initialize separately.

1852 * sem_res.adb (Resolve_Membership_Op): Allow the use of the membership
1853 test when the left operand is a class-wide interface and the right
1854 operand is not a class-wide type.
1855 * exp_ch4.adb (Tagged_Membership): Adding support for interface as the
1858 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1860 * exp_aggr.adb (Flatten): A quantified expression cannot be duplicated
1861 in an others clause to prevent visibility issues with the generated
1863 (Component_OK_For_Backend): Return false for a quantified expression.
1864 (Check_Static_Component): Ditto.
1866 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1868 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
1869 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
1870 into three distring cases rather than in one loop which attempts to
1871 handle all three cases. This rewrite eliminates an issue where the last
1872 frame of the stack cannot be freed, thus causing the memory range of a
1873 new frame to approach the overflow point of the memory index type.
1874 Since the overflow is logically treated as a
1875 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
1876 (SS_Allocate_Static): New routine. The routine factorizes the static
1877 secondary stack-related code from the former SS_Allocate.
1879 2018-05-25 Sergey Rybin <rybin@adacore.com>
1881 * doc/gnat_ugn/gnat_and_program_execution.rst: Add description of '-U'
1882 option for gnatelim.
1884 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1886 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create
1887 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
1888 is created when the proper body of the stub is analyzed.
1889 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
1890 is the proper body of a subunit, the cloned body must be inserted in
1891 the declarative list that contains the stub.
1893 2018-05-25 Justin Squirek <squirek@adacore.com>
1895 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
1896 generate code for 6.5(8-10) so that we don't get an assertion error
1897 when dealing with an incomplete return type.
1899 2018-05-25 Arnaud Charlet <charlet@adacore.com>
1901 * pprint.adb (Expression_Name): Strip too long expressions to avoid
1902 carrying very large strings.

1928 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1930 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
1931 Validate_Derived_Type_Instance, to verify that all interfaces
1932 implemented by the formal type are also implemented by the actual. The
1933 verification is complicated when an interface of the formal is declared
1934 in a generic unit and the actual is declared in an instance of it.
1935 There is currently no mechanism to relate an interface declared within
1936 a generic to the corresponding interface in an instance, so we must
1937 traverse the list of interfaces of the actual, looking for a name
1938 match, and verifying that that interface is declared in an instance.
1940 2018-05-25 Piotr Trojanek <trojanek@adacore.com>
1942 * sem_util.adb (Iterate_Call_Parameters): Rewrite with extra
1943 assertions; replace function versions of Next_Formal/Next_Actual with
1944 their procedural versions (which are more concise).

1978 boolean type with convention C.
1979 * libgnat/i-cexten.ads (bool): Change to boolean with convention C.
1980 * gcc-interface/decl.c (gnat_to_gnu_entity): Add new local variable

1985 <E_Record_Type>: Force the size of a storage unit on empty classes.
1986 * gcc-interface/utils.c (make_type_from_size) <BOOLEAN_TYPE>: Skip
1987 boolean types with precision 1 if the size is the expected one.

2005 prefixes of array attributes, to prefixes that are entity names whose
2006 type is constrained.
2007 (Note_Uplevel_Bound): Verify that the bound is declared in an enclosing
2008 subprogram, as itype created for loops in pre/postcondition may appear
2009 in loops at the library level.
2011 2018-05-25 Ed Schonberg <schonberg@adacore.com>
2013 * sem_ch13.adb (Build_Predicate_Functions): The predicate function
2014 declaration is inserted into the tree and analyzed at that point, so
2015 should not be reinserted when the body is constructed. Inside a
2016 generic, ensure that the body is not inserted twice in the tree.

3050 (Unit_Entity): New routine.
3051 * sem_prag.adb (Analyze_Pragma): Reimplement the handling of pragma
3052 Elaboration_Checks. The analysis now ensures that the pragma appears at
3053 the configuration level, and on the initial declaration of a unit.
3054 Other placements are either flagged as illegal, or ignored.
3055 (Check_Duplicate_Elaboration_Checks_Pragma): New routine.
3056 (Ignore_Elaboration_Checks_Pragma): New routine.

3066 of empty string when argv[0] couldn't be found on PATH.
3067 (Enable_Cache): Raise Program_Error instead of attempting a null
3068 pointer dereference when the Exec_Module initialization failed.

3087 * sem_util.adb (Find_Simple_Properties): New routine.
3088 (Is_Enabled_External_Property): New routine.
3089 (State_Has_Enabled_Property): Reimplemented. The two flavors of option
3090 External have precedence over option Synchronous when determining
3091 whether a property is in effect.

3111 Address, and type of Low, High to Storage_Offset.
3112 (Low): Rename as Low_Address and convey that the return value is a
3113 runtime reference accounting for a load address.

3115 address/offset type changes.
3116 (Aranges_Lookup): Likewise.

3169 attribute reference is legal within a generic unit when the prefix is a
3170 formal private type.
3172 2018-05-21 Hristian Kirtchev <kirtchev@adacore.com>
3174 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
3175 delegate the secondary stack management when there is no suitable
3176 transient context, and the transient scope was intended to manage the
3177 secondary stack because this causes premature reclamation. Change the
3178 transient scope creation logic by special casing assignment statements
3179 of controlled components for type initialization procedures.
3180 (Find_Node_To_Be_Wrapped): Renamed to Find_Transient_Context. Update
3181 the comment on usage.
3182 (Find_Transient_Context): Change the initinte loop into a while loop.
3183 Iterations schemes and iterator specifications are not valid transient
3184 contexts because they rely on special processing. Assignment statements
3185 are now treated as a normal transient context, special cases are
3186 handled by the caller. Add special processing for pragma Check.
3187 (Is_OK_Construct): Removed. Its functionality has been merged in
3188 routine Find_Transient_Context.
3189 * sem_ch5.adb (Check_Call): Reimplemented. Add code to properly
3190 retrieve the subprogram being invoked. Use a more accurate predicate
3191 (Requires_Transient_Scope) to determine that the function will emply
3192 the secondary stack.

3394 suitable construct to wrap, and the transient scope was intended to
3395 manage the secondary stack.
3396 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
3397 is a valid boundary for a transient expression which comes from the

3410 actions are required by utilizing predicate Needs_Finalization rather
3412 (Resolve_Call): Type initialization procedures can now utilize
3413 transient scopes to manage the secondary stack, thus preventing leaks
3414 during initialization. Remove the previous kludgy algorithm which
3415 attempts to manage the secondary stack at the object creation site.

3550 completes the implementation of AI12-0166.
3552 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3554 * ali.adb: Document the remaining letters available for ALI lines.
3555 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
3556 * ali.ads: Update type With_Record. Field
3557 Implicit_With_From_Instantiation is no longer in use. Add field
3559 * csinfo.adb (CSinfo): Remove the setup for attribute
3560 Implicit_With_From_Instantiation.
3561 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
3562 either implicitly or explicitly withed.
3563 (Is_Implicit_With_Clause): New routine.
3564 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
3565 confusion with the with clause attribute by the same name.
3566 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
3567 * rtsfind.adb (Maybe_Add_With): Code cleanup.
3568 * sem_ch8.adb (Present_System_Aux): Code cleanup.
3569 * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
3571 (Implicit_With_On_Parent): Mark the with clause as generated for a
3573 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
3574 instantiation are no longer marked as Implicit_With_From_Instantiation
3575 because they are already marked as implicit.
3576 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
3577 which marks implicit with clauses as related to an instantiation.
3578 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
3579 (Parent_With): New routine.
3580 (Set_Implicit_With_From_Instantiation): Removed.
3581 (Set_Parent_With): New routine.
3582 * sinfo.ads: Update the documentation of attribute Implicit_With.
3583 Remove attribute Implicit_With_From_Instantiation along with
3584 occurrences in nodes. Add attribute Parent_With along with occurrences
3586 (Implicit_With_From_Instantiation): Removed along with pragma Inline.
3587 (Parent_With): New routine along with pragma Inline.
3588 (Set_Implicit_With_From_Instantiation): Removed along with pragma Inline.
3589 (Set_Parent_With): New routine along with pragma Inline.
3591 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3593 * sem_util.adb (Find_Enclosing_Scope): Return the unique defining
3594 entity when the enclosing construct is a body.
3596 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
3598 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
3599 Secondary_Stack_Size handling as a pragma is now generated for the
3600 corresponding aspect instead of an attribute. Pragma expression is
3601 relocated instead of evaluated. Discriminant of the corresponding
3602 record type is referenced rather than the type discriminant.
3603 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
3604 Secondary_Stack_Size rep item checks to only look for the pragma rep.
3605 * sem_ch13.adb (Analyze_One_Aspect): Transform
3606 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
3607 because the attribute does not have visibility on a task type's
3608 discriminants when the type's definition is expanded.
3609 (Analyze_Attribute_Definition_Clause): Remove handling of
3610 Attribute_Secondary_Stack_Size.
3611 * snames.adb-tmpl, snames.ads-tmpl: Remove
3612 Attribute_Secondary_Stack_Size, no longer used.
3614 2018-01-11 Justin Squirek <squirek@adacore.com>
3616 * sem_ch8.adb: Minor comment fix.
3618 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3620 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
3621 individual action because the action may denote a complex expression,
3622 such as a case statement, which in turn may contain additional
3625 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3627 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
3628 analysis on a copy of the expression with a copy of the index variable,
3629 because full expansion will rewrite construct into a loop with the
3630 original loop variable.
3631 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
3632 expression is an iterated component association. Full analysis takes
3633 place when construct is rewritten as a loop.
3634 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
3635 is not safe for in-place assignment.
3636 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
3637 entity with no homonym and no other entity in the scope.
3639 2018-01-11 Justin Squirek <squirek@adacore.com>
3641 * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
3642 message to be printed on the pragma argument identifier.
3644 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3646 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
3647 entity of the generated invariant procedure in order to construct a
3648 proper entity chain.
3650 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
3652 * sem_ch13.adb (Build_Predicate_Functions): Fix minor issues in
3655 2018-01-11 Arnaud Charlet <charlet@adacore.com>
3657 * einfo.ads, einfo.adb (Activation_Record_Component,
3658 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
3659 Allow E_Discriminant.
3661 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
3663 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
3664 for atomic access once the component size is taken into account and
3665 also do it if the component type is Atomic or Volatile_Full_Access.
3667 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
3669 * gnatvsn.ads: Bump copyright year.

3672 Alan Hayward <alan.hayward@arm.com>
3673 David Sherwood <david.sherwood@arm.com>
3675 * gcc-interface/misc.c (enumerate_modes): Treat GET_MODE_BITSIZE

3679 Alan Hayward <alan.hayward@arm.com>
3680 David Sherwood <david.sherwood@arm.com>

3686 Alan Hayward <alan.hayward@arm.com>
3687 David Sherwood <david.sherwood@arm.com>
3689 * gcc-interface/utils.c (gnat_types_compatible_p): Handle
3690 polynomial TYPE_VECTOR_SUBPARTS.
3692 2018-01-03 Richard Sandiford <richard.sandiford@linaro.org>
3693 Alan Hayward <alan.hayward@arm.com>
