1235 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
1236 delegate the secondary stack management when there is no suitable
1237 transient context, and the transient scope was intended to manage the

1242 the comment on usage.
1243 (Find_Transient_Context): Change the initinte loop into a while loop.

1537 * libgnat/a-direio.ads, libgnat/a-sequio.ads, libgnat/a-ststio.ads,
1538 libgnat/a-textio.ads, libgnat/a-witeio.ads, libgnat/a-ztexio.ads
1539 (File_Type): Add Default_Initial_Condition aspect.
1541 2018-01-11 Pascal Obry <obry@adacore.com>
1543 * libgnat/s-os_lib.adb (Normalize_Pathname): New implementation.
1545 2018-01-11 Bob Duff <duff@adacore.com>
1547 * doc/gnat_ugn/gnat_utility_programs.rst: Rewrite gnatpp documentation
1548 to match what the Libadalang-based version does.
1549 * doc/gnat_ugn/about_this_guide.rst: Update reference.
1551 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1553 * sem_res.adb (Uses_SS): A controlled type requires the secondary stack
1554 if it contains at least one component declaration employing a function
1555 call returning on the secondary stack.
1557 2018-01-11 Yannick Moy <moy@adacore.com>
1559 * doc/gnat_rm/standard_and_implementation_defined_restrictions.rst:
1560 Update description of restriction SPARK_05 with SPARK 2014.

1563 2018-01-11 Vasiliy Fofanov <fofanov@adacore.com>
1565 * doc/gnat_ugn/gnat_utility_programs.rst: Fix layout.
1567 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1569 * exp_aggr.adb, exp_ch9.adb, exp_util.adb, sem_aggr.adb, sem_ch3.adb,
1570 sem_res.adb, sem_util.adb: Minor reformatting.
1572 2018-01-11 Ed Schonberg <schonberg@adacore.com>
1574 * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
1575 has a delayed aspect which must be processed at the point the type is
1576 frozen. This mimics what is done when the predicate is provided by a
1579 2018-01-11 Doug Rupp <rupp@adacore.com>
1581 * init.c (vxworks): Add macro checks for __aarch64__.
1583 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1585 * exp_util.adb (Add_Failure_Expression): New routine.
1586 (Make_Predicate_Check): Reimplement the handling of Predicate_Failure.
1587 * sem_util.adb (Is_Current_Instance): Code cleanup.
1589 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
1591 * libgnat/s-parame*.adb, libgnat/s-parame*.ads: Remove unneeded
1592 Default_Sec_Stack_Size.
1593 * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
1594 limit check so that the integer index does not overflow. Check the
1595 dynamic stack allocation does not cause the secondary stack pointer to
1597 (SS_Info): Align colons.
1598 (SS_Init): Cover the case when bootstraping with an old compiler that
1599 does not set Default_SS_Size.
1601 2018-01-11 Ed Schonberg <schonberg@adacore.com>
1603 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
1604 legality of an inherited operation that may require overriding, ignore
1605 primitive_wrappers that correspond to explicit operations that override
1606 an interface primitive.
1607 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
1608 operation to which the class-wide expression applies is a protected op.
1609 with a primitive_wrapper, verify that the updated inherited expression
1610 does not contain an internal call to a protected function. This
1611 completes the implementation of AI12-0166.
1613 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1615 * ali.adb: Document the remaining letters available for ALI lines.
1616 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
1617 * ali.ads: Update type With_Record. Field
1618 Implicit_With_From_Instantiation is no longer in use. Add field
1620 * csinfo.adb (CSinfo): Remove the setup for attribute
1621 Implicit_With_From_Instantiation.
1622 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
1623 either implicitly or explicitly withed.
1624 (Is_Implicit_With_Clause): New routine.
1625 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
1626 confusion with the with clause attribute by the same name.
1627 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
1628 * rtsfind.adb (Maybe_Add_With): Code cleanup.
1629 * sem_ch8.adb (Present_System_Aux): Code cleanup.
1630 * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
1632 (Implicit_With_On_Parent): Mark the with clause as generated for a
1634 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
1635 instantiation are no longer marked as Implicit_With_From_Instantiation
1636 because they are already marked as implicit.
1637 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
1638 which marks implicit with clauses as related to an instantiation.
1639 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
1640 (Parent_With): New routine.
1641 (Set_Implicit_With_From_Instantiation): Removed.
1642 (Set_Parent_With): New routine.
1643 * sinfo.ads: Update the documentation of attribute Implicit_With.
1644 Remove attribute Implicit_With_From_Instantiation along with
1645 occurrences in nodes. Add attribute Parent_With along with occurrences
1647 (Implicit_With_From_Instantiation): Removed along with pragma Inline.
1648 (Parent_With): New routine along with pragma Inline.
1649 (Set_Implicit_With_From_Instantiation): Removed along with pragma Inline.
1650 (Set_Parent_With): New routine along with pragma Inline.
1652 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1654 * sem_util.adb (Find_Enclosing_Scope): Return the unique defining
1655 entity when the enclosing construct is a body.
1657 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
1659 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
1660 Secondary_Stack_Size handling as a pragma is now generated for the
1661 corresponding aspect instead of an attribute. Pragma expression is
1662 relocated instead of evaluated. Discriminant of the corresponding
1663 record type is referenced rather than the type discriminant.
1664 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
1665 Secondary_Stack_Size rep item checks to only look for the pragma rep.
1666 * sem_ch13.adb (Analyze_One_Aspect): Transform
1667 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
1668 because the attribute does not have visibility on a task type's
1669 discriminants when the type's definition is expanded.
1670 (Analyze_Attribute_Definition_Clause): Remove handling of
1671 Attribute_Secondary_Stack_Size.
1672 * snames.adb-tmpl, snames.ads-tmpl: Remove
1673 Attribute_Secondary_Stack_Size, no longer used.
1675 2018-01-11 Justin Squirek <squirek@adacore.com>
1677 * sem_ch8.adb: Minor comment fix.
1679 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1681 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
1682 individual action because the action may denote a complex expression,
1683 such as a case statement, which in turn may contain additional
1686 2018-01-11 Ed Schonberg <schonberg@adacore.com>
1688 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
1689 analysis on a copy of the expression with a copy of the index variable,
1690 because full expansion will rewrite construct into a loop with the
1691 original loop variable.
1692 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
1693 expression is an iterated component association. Full analysis takes
1694 place when construct is rewritten as a loop.
1695 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
1696 is not safe for in-place assignment.
1697 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
1698 entity with no homonym and no other entity in the scope.
1700 2018-01-11 Justin Squirek <squirek@adacore.com>
1702 * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
1703 message to be printed on the pragma argument identifier.
1705 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1707 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
1708 entity of the generated invariant procedure in order to construct a
1709 proper entity chain.
1711 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
1713 * sem_ch13.adb (Build_Predicate_Functions): Fix minor issues in
1716 2018-01-11 Arnaud Charlet <charlet@adacore.com>
1718 * einfo.ads, einfo.adb (Activation_Record_Component,
1719 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
1720 Allow E_Discriminant.
1722 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
1724 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
1725 for atomic access once the component size is taken into account and
1726 also do it if the component type is Atomic or Volatile_Full_Access.
1728 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
1730 * gnatvsn.ads: Bump copyright year.

1733 Alan Hayward <alan.hayward@arm.com>
1734 David Sherwood <david.sherwood@arm.com>

1747 Alan Hayward <alan.hayward@arm.com>
1748 David Sherwood <david.sherwood@arm.com>
1750 * gcc-interface/utils.c (gnat_types_compatible_p): Handle
1751 polynomial TYPE_VECTOR_SUBPARTS.
1753 2018-01-03 Richard Sandiford <richard.sandiford@linaro.org>
1754 Alan Hayward <alan.hayward@arm.com>
1755 David Sherwood <david.sherwood@arm.com>

1760 2018-01-03 Jakub Jelinek <jakub@redhat.com>
1762 Update copyright years.
1764 * gnat_ugn.texi: Bump @copying's copyright year.
