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

13 in a generic unit and the actual is declared in an instance of it.
14 There is currently no mechanism to relate an interface declared within
15 a generic to the corresponding interface in an instance, so we must
16 traverse the list of interfaces of the actual, looking for a name
17 match, and verifying that that interface is declared in an instance.

1253 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
1254 delegate the secondary stack management when there is no suitable
1255 transient context, and the transient scope was intended to manage the

1260 the comment on usage.
1261 (Find_Transient_Context): Change the initinte loop into a while loop.

1267 routine Find_Transient_Context.
1268 * sem_ch5.adb (Check_Call): Reimplemented. Add code to properly

1492 transient scopes to manage the secondary stack, thus preventing leaks
1493 during initialization. Remove the previous kludgy algorithm which
1494 attempts to manage the secondary stack at the object creation site.

1533 * doc/gnat_rm/implementation_defined_aspects.rst: Minor type/wording
1535 * gnat_rm.texi: Regenerate.
1537 2018-01-11 Ed Schonberg <schonberg@adacore.com>
1539 * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the
1540 formsl type corresponding to the actual fixed point type is private,
1541 because in this case there can be no suspicious arithmetic operations
1542 in the generic unless they reference a formal subprogram. Clarify
1545 2018-01-11 Javier Miranda <miranda@adacore.com>
1547 * exp_util.adb (Remove_Side_Effects): No action done for functions
1548 returning class-wide types since it requires generating code using
1549 'reference and the CCG target has no secondary stack.
1550 * gnat1drv.adb: Disable building static dispatch tables when generating
1553 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
1555 * libgnat/a-direio.ads, libgnat/a-sequio.ads, libgnat/a-ststio.ads,
1556 libgnat/a-textio.ads, libgnat/a-witeio.ads, libgnat/a-ztexio.ads
1557 (File_Type): Add Default_Initial_Condition aspect.
1559 2018-01-11 Pascal Obry <obry@adacore.com>
1561 * libgnat/s-os_lib.adb (Normalize_Pathname): New implementation.
1563 2018-01-11 Bob Duff <duff@adacore.com>
1565 * doc/gnat_ugn/gnat_utility_programs.rst: Rewrite gnatpp documentation
1566 to match what the Libadalang-based version does.
1567 * doc/gnat_ugn/about_this_guide.rst: Update reference.
1569 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1571 * sem_res.adb (Uses_SS): A controlled type requires the secondary stack
1572 if it contains at least one component declaration employing a function
1573 call returning on the secondary stack.
1575 2018-01-11 Yannick Moy <moy@adacore.com>
1577 * doc/gnat_rm/standard_and_implementation_defined_restrictions.rst:
1578 Update description of restriction SPARK_05 with SPARK 2014.
1579 * gnat_rm.texi: Regenerate.
1581 2018-01-11 Vasiliy Fofanov <fofanov@adacore.com>
1583 * doc/gnat_ugn/gnat_utility_programs.rst: Fix layout.
1585 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1587 * exp_aggr.adb, exp_ch9.adb, exp_util.adb, sem_aggr.adb, sem_ch3.adb,
1588 sem_res.adb, sem_util.adb: Minor reformatting.
1590 2018-01-11 Ed Schonberg <schonberg@adacore.com>
1592 * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
1593 has a delayed aspect which must be processed at the point the type is
1594 frozen. This mimics what is done when the predicate is provided by a
1597 2018-01-11 Doug Rupp <rupp@adacore.com>
1599 * init.c (vxworks): Add macro checks for __aarch64__.
1601 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1603 * exp_util.adb (Add_Failure_Expression): New routine.
1604 (Make_Predicate_Check): Reimplement the handling of Predicate_Failure.
1605 * sem_util.adb (Is_Current_Instance): Code cleanup.
1607 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
1609 * libgnat/s-parame*.adb, libgnat/s-parame*.ads: Remove unneeded
1610 Default_Sec_Stack_Size.
1611 * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
1612 limit check so that the integer index does not overflow. Check the
1613 dynamic stack allocation does not cause the secondary stack pointer to
1615 (SS_Info): Align colons.
1616 (SS_Init): Cover the case when bootstraping with an old compiler that
1617 does not set Default_SS_Size.
1619 2018-01-11 Ed Schonberg <schonberg@adacore.com>
1621 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
1622 legality of an inherited operation that may require overriding, ignore
1623 primitive_wrappers that correspond to explicit operations that override
1624 an interface primitive.
1625 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
1626 operation to which the class-wide expression applies is a protected op.
1627 with a primitive_wrapper, verify that the updated inherited expression
1628 does not contain an internal call to a protected function. This
1629 completes the implementation of AI12-0166.
1631 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1633 * ali.adb: Document the remaining letters available for ALI lines.
1634 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
1635 * ali.ads: Update type With_Record. Field
1636 Implicit_With_From_Instantiation is no longer in use. Add field
1638 * csinfo.adb (CSinfo): Remove the setup for attribute
1639 Implicit_With_From_Instantiation.
1640 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
1641 either implicitly or explicitly withed.
1642 (Is_Implicit_With_Clause): New routine.
1643 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
1644 confusion with the with clause attribute by the same name.
1645 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
1646 * rtsfind.adb (Maybe_Add_With): Code cleanup.
1647 * sem_ch8.adb (Present_System_Aux): Code cleanup.
1648 * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
1650 (Implicit_With_On_Parent): Mark the with clause as generated for a
1652 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
1653 instantiation are no longer marked as Implicit_With_From_Instantiation
1654 because they are already marked as implicit.
1655 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
1656 which marks implicit with clauses as related to an instantiation.
1657 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
1658 (Parent_With): New routine.
1659 (Set_Implicit_With_From_Instantiation): Removed.
1660 (Set_Parent_With): New routine.
1661 * sinfo.ads: Update the documentation of attribute Implicit_With.
1662 Remove attribute Implicit_With_From_Instantiation along with
1663 occurrences in nodes. Add attribute Parent_With along with occurrences
1665 (Implicit_With_From_Instantiation): Removed along with pragma Inline.
1666 (Parent_With): New routine along with pragma Inline.
1667 (Set_Implicit_With_From_Instantiation): Removed along with pragma Inline.
1668 (Set_Parent_With): New routine along with pragma Inline.
1670 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1672 * sem_util.adb (Find_Enclosing_Scope): Return the unique defining
1673 entity when the enclosing construct is a body.
1675 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
1677 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
1678 Secondary_Stack_Size handling as a pragma is now generated for the
1679 corresponding aspect instead of an attribute. Pragma expression is
1680 relocated instead of evaluated. Discriminant of the corresponding
1681 record type is referenced rather than the type discriminant.
1682 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
1683 Secondary_Stack_Size rep item checks to only look for the pragma rep.
1684 * sem_ch13.adb (Analyze_One_Aspect): Transform
1685 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
1686 because the attribute does not have visibility on a task type's
1687 discriminants when the type's definition is expanded.
1688 (Analyze_Attribute_Definition_Clause): Remove handling of
1689 Attribute_Secondary_Stack_Size.
1690 * snames.adb-tmpl, snames.ads-tmpl: Remove
1691 Attribute_Secondary_Stack_Size, no longer used.
1693 2018-01-11 Justin Squirek <squirek@adacore.com>
1695 * sem_ch8.adb: Minor comment fix.
1697 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1699 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
1700 individual action because the action may denote a complex expression,
1701 such as a case statement, which in turn may contain additional
1704 2018-01-11 Ed Schonberg <schonberg@adacore.com>
1706 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
1707 analysis on a copy of the expression with a copy of the index variable,
1708 because full expansion will rewrite construct into a loop with the
1709 original loop variable.
1710 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
1711 expression is an iterated component association. Full analysis takes
1712 place when construct is rewritten as a loop.
1713 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
1714 is not safe for in-place assignment.
1715 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
1716 entity with no homonym and no other entity in the scope.
1718 2018-01-11 Justin Squirek <squirek@adacore.com>
1720 * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
1721 message to be printed on the pragma argument identifier.
1723 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1725 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
1726 entity of the generated invariant procedure in order to construct a
1727 proper entity chain.
1729 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
1731 * sem_ch13.adb (Build_Predicate_Functions): Fix minor issues in
1734 2018-01-11 Arnaud Charlet <charlet@adacore.com>
1736 * einfo.ads, einfo.adb (Activation_Record_Component,
1737 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
1738 Allow E_Discriminant.
1740 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
1742 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
1743 for atomic access once the component size is taken into account and
1744 also do it if the component type is Atomic or Volatile_Full_Access.
1746 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
1748 * gnatvsn.ads: Bump copyright year.

1751 Alan Hayward <alan.hayward@arm.com>
1752 David Sherwood <david.sherwood@arm.com>

1765 Alan Hayward <alan.hayward@arm.com>
1766 David Sherwood <david.sherwood@arm.com>
1768 * gcc-interface/utils.c (gnat_types_compatible_p): Handle
1769 polynomial TYPE_VECTOR_SUBPARTS.
1771 2018-01-03 Richard Sandiford <richard.sandiford@linaro.org>
1772 Alan Hayward <alan.hayward@arm.com>
1773 David Sherwood <david.sherwood@arm.com>
