1063 * sem_prag.adb (Analyze_Pragma): Reimplement the handling of pragma
1064 Elaboration_Checks. The analysis now ensures that the pragma appears at
1065 the configuration level, and on the initial declaration of a unit.
1066 Other placements are either flagged as illegal, or ignored.

1186 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
1187 delegate the secondary stack management when there is no suitable
1188 transient context, and the transient scope was intended to manage the

1190 transient scope creation logic by special casing assignment statements
1191 of controlled components for type initialization procedures.
1192 (Find_Node_To_Be_Wrapped): Renamed to Find_Transient_Context. Update
1193 the comment on usage.
1194 (Find_Transient_Context): Change the initinte loop into a while loop.

1196 contexts because they rely on special processing. Assignment statements
1197 are now treated as a normal transient context, special cases are
1198 handled by the caller. Add special processing for pragma Check.

1200 routine Find_Transient_Context.
1201 * sem_ch5.adb (Check_Call): Reimplemented. Add code to properly

1409 is a valid boundary for a transient expression which comes from the

1422 actions are required by utilizing predicate Needs_Finalization rather
1424 (Resolve_Call): Type initialization procedures can now utilize
1425 transient scopes to manage the secondary stack, thus preventing leaks
1426 during initialization. Remove the previous kludgy algorithm which
1427 attempts to manage the secondary stack at the object creation site.

1545 limit check so that the integer index does not overflow. Check the
1546 dynamic stack allocation does not cause the secondary stack pointer to
1548 (SS_Info): Align colons.
1549 (SS_Init): Cover the case when bootstraping with an old compiler that
1550 does not set Default_SS_Size.
1552 2018-01-11 Ed Schonberg <schonberg@adacore.com>
1554 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
1555 legality of an inherited operation that may require overriding, ignore
1556 primitive_wrappers that correspond to explicit operations that override
1557 an interface primitive.
1558 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
1559 operation to which the class-wide expression applies is a protected op.
1560 with a primitive_wrapper, verify that the updated inherited expression
1561 does not contain an internal call to a protected function. This
1562 completes the implementation of AI12-0166.
1564 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1566 * ali.adb: Document the remaining letters available for ALI lines.
1567 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
1568 * ali.ads: Update type With_Record. Field
1569 Implicit_With_From_Instantiation is no longer in use. Add field
1571 * csinfo.adb (CSinfo): Remove the setup for attribute
1572 Implicit_With_From_Instantiation.
1573 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
1574 either implicitly or explicitly withed.
1575 (Is_Implicit_With_Clause): New routine.
1576 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
1577 confusion with the with clause attribute by the same name.
1578 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
1579 * rtsfind.adb (Maybe_Add_With): Code cleanup.
1580 * sem_ch8.adb (Present_System_Aux): Code cleanup.
1581 * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
1583 (Implicit_With_On_Parent): Mark the with clause as generated for a
1585 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
1586 instantiation are no longer marked as Implicit_With_From_Instantiation
1587 because they are already marked as implicit.
1588 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
1589 which marks implicit with clauses as related to an instantiation.
1590 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
1591 (Parent_With): New routine.
1592 (Set_Implicit_With_From_Instantiation): Removed.
1593 (Set_Parent_With): New routine.
1594 * sinfo.ads: Update the documentation of attribute Implicit_With.
1595 Remove attribute Implicit_With_From_Instantiation along with
1596 occurrences in nodes. Add attribute Parent_With along with occurrences
1598 (Implicit_With_From_Instantiation): Removed along with pragma Inline.
1599 (Parent_With): New routine along with pragma Inline.
1600 (Set_Implicit_With_From_Instantiation): Removed along with pragma Inline.
1601 (Set_Parent_With): New routine along with pragma Inline.
1603 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1605 * sem_util.adb (Find_Enclosing_Scope): Return the unique defining
1606 entity when the enclosing construct is a body.
1608 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
1610 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
1611 Secondary_Stack_Size handling as a pragma is now generated for the
1612 corresponding aspect instead of an attribute. Pragma expression is
1613 relocated instead of evaluated. Discriminant of the corresponding
1614 record type is referenced rather than the type discriminant.
1615 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
1616 Secondary_Stack_Size rep item checks to only look for the pragma rep.
1617 * sem_ch13.adb (Analyze_One_Aspect): Transform
1618 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
1619 because the attribute does not have visibility on a task type's
1620 discriminants when the type's definition is expanded.
1621 (Analyze_Attribute_Definition_Clause): Remove handling of
1622 Attribute_Secondary_Stack_Size.
1623 * snames.adb-tmpl, snames.ads-tmpl: Remove
1624 Attribute_Secondary_Stack_Size, no longer used.
1626 2018-01-11 Justin Squirek <squirek@adacore.com>
1628 * sem_ch8.adb: Minor comment fix.
1630 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1632 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
1633 individual action because the action may denote a complex expression,
1634 such as a case statement, which in turn may contain additional
1637 2018-01-11 Ed Schonberg <schonberg@adacore.com>
1639 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
1640 analysis on a copy of the expression with a copy of the index variable,
1641 because full expansion will rewrite construct into a loop with the
1642 original loop variable.
1643 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
1644 expression is an iterated component association. Full analysis takes
1645 place when construct is rewritten as a loop.
1646 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
1647 is not safe for in-place assignment.
1648 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
1649 entity with no homonym and no other entity in the scope.
1651 2018-01-11 Justin Squirek <squirek@adacore.com>
1653 * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
1654 message to be printed on the pragma argument identifier.
1656 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1658 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
1659 entity of the generated invariant procedure in order to construct a
1660 proper entity chain.
1662 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
1664 * sem_ch13.adb (Build_Predicate_Functions): Fix minor issues in
1667 2018-01-11 Arnaud Charlet <charlet@adacore.com>
1669 * einfo.ads, einfo.adb (Activation_Record_Component,
1670 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
1671 Allow E_Discriminant.
1673 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
1675 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
1676 for atomic access once the component size is taken into account and
1677 also do it if the component type is Atomic or Volatile_Full_Access.
1679 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
1681 * gnatvsn.ads: Bump copyright year.
1683 2018-01-03 Richard Sandiford <richard.sandiford@linaro.org>
1684 Alan Hayward <alan.hayward@arm.com>
1685 David Sherwood <david.sherwood@arm.com>
1687 * gcc-interface/misc.c (enumerate_modes): Treat GET_MODE_BITSIZE

1691 Alan Hayward <alan.hayward@arm.com>
1692 David Sherwood <david.sherwood@arm.com>

1698 Alan Hayward <alan.hayward@arm.com>
1699 David Sherwood <david.sherwood@arm.com>
1701 * gcc-interface/utils.c (gnat_types_compatible_p): Handle
1702 polynomial TYPE_VECTOR_SUBPARTS.
1704 2018-01-03 Richard Sandiford <richard.sandiford@linaro.org>
1705 Alan Hayward <alan.hayward@arm.com>
1706 David Sherwood <david.sherwood@arm.com>
1708 * gcc-interface/misc.c (enumerate_modes): Handle polynomial
1711 2018-01-03 Jakub Jelinek <jakub@redhat.com>
1713 Update copyright years.
1715 * gnat_ugn.texi: Bump @copying's copyright year.
