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

22 in a generic unit and the actual is declared in an instance of it.
23 There is currently no mechanism to relate an interface declared within
24 a generic to the corresponding interface in an instance, so we must
25 traverse the list of interfaces of the actual, looking for a name
26 match, and verifying that that interface is declared in an instance.

1262 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
1263 delegate the secondary stack management when there is no suitable
1264 transient context, and the transient scope was intended to manage the

1269 the comment on usage.
1270 (Find_Transient_Context): Change the initinte loop into a while loop.

1276 routine Find_Transient_Context.

1544 * gnat_rm.texi: Regenerate.
1546 2018-01-11 Ed Schonberg <schonberg@adacore.com>
1548 * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the
1549 formsl type corresponding to the actual fixed point type is private,
1550 because in this case there can be no suspicious arithmetic operations
1551 in the generic unless they reference a formal subprogram. Clarify
1554 2018-01-11 Javier Miranda <miranda@adacore.com>
1556 * exp_util.adb (Remove_Side_Effects): No action done for functions
1557 returning class-wide types since it requires generating code using
1558 'reference and the CCG target has no secondary stack.
1559 * gnat1drv.adb: Disable building static dispatch tables when generating
1562 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
1564 * libgnat/a-direio.ads, libgnat/a-sequio.ads, libgnat/a-ststio.ads,

1566 (File_Type): Add Default_Initial_Condition aspect.
1568 2018-01-11 Pascal Obry <obry@adacore.com>
1570 * libgnat/s-os_lib.adb (Normalize_Pathname): New implementation.
1572 2018-01-11 Bob Duff <duff@adacore.com>
1574 * doc/gnat_ugn/gnat_utility_programs.rst: Rewrite gnatpp documentation
1575 to match what the Libadalang-based version does.
1576 * doc/gnat_ugn/about_this_guide.rst: Update reference.
1578 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1580 * sem_res.adb (Uses_SS): A controlled type requires the secondary stack
1581 if it contains at least one component declaration employing a function
1582 call returning on the secondary stack.
1584 2018-01-11 Yannick Moy <moy@adacore.com>
1586 * doc/gnat_rm/standard_and_implementation_defined_restrictions.rst:

1596 * exp_aggr.adb, exp_ch9.adb, exp_util.adb, sem_aggr.adb, sem_ch3.adb,
1597 sem_res.adb, sem_util.adb: Minor reformatting.
1599 2018-01-11 Ed Schonberg <schonberg@adacore.com>
1601 * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
1602 has a delayed aspect which must be processed at the point the type is
1603 frozen. This mimics what is done when the predicate is provided by a
1606 2018-01-11 Doug Rupp <rupp@adacore.com>
1608 * init.c (vxworks): Add macro checks for __aarch64__.
1610 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1612 * exp_util.adb (Add_Failure_Expression): New routine.

1619 Default_Sec_Stack_Size.
1620 * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
1621 limit check so that the integer index does not overflow. Check the
1622 dynamic stack allocation does not cause the secondary stack pointer to
1624 (SS_Info): Align colons.
1625 (SS_Init): Cover the case when bootstraping with an old compiler that
1626 does not set Default_SS_Size.
1628 2018-01-11 Ed Schonberg <schonberg@adacore.com>
1630 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
1631 legality of an inherited operation that may require overriding, ignore
1632 primitive_wrappers that correspond to explicit operations that override
1633 an interface primitive.
1634 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
1635 operation to which the class-wide expression applies is a protected op.
1636 with a primitive_wrapper, verify that the updated inherited expression
1637 does not contain an internal call to a protected function. This
1638 completes the implementation of AI12-0166.
1640 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1642 * ali.adb: Document the remaining letters available for ALI lines.
1643 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
1644 * ali.ads: Update type With_Record. Field
1645 Implicit_With_From_Instantiation is no longer in use. Add field
1647 * csinfo.adb (CSinfo): Remove the setup for attribute
1648 Implicit_With_From_Instantiation.
1649 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
1650 either implicitly or explicitly withed.
1651 (Is_Implicit_With_Clause): New routine.
1652 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
1653 confusion with the with clause attribute by the same name.
1654 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
1655 * rtsfind.adb (Maybe_Add_With): Code cleanup.
1656 * sem_ch8.adb (Present_System_Aux): Code cleanup.
1657 * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
1659 (Implicit_With_On_Parent): Mark the with clause as generated for a
1661 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
1662 instantiation are no longer marked as Implicit_With_From_Instantiation
1663 because they are already marked as implicit.
1664 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
1665 which marks implicit with clauses as related to an instantiation.
1666 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
1667 (Parent_With): New routine.
1668 (Set_Implicit_With_From_Instantiation): Removed.
1669 (Set_Parent_With): New routine.
1670 * sinfo.ads: Update the documentation of attribute Implicit_With.
1671 Remove attribute Implicit_With_From_Instantiation along with
1672 occurrences in nodes. Add attribute Parent_With along with occurrences
1674 (Implicit_With_From_Instantiation): Removed along with pragma Inline.
1675 (Parent_With): New routine along with pragma Inline.
1676 (Set_Implicit_With_From_Instantiation): Removed along with pragma Inline.
1677 (Set_Parent_With): New routine along with pragma Inline.
1679 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1681 * sem_util.adb (Find_Enclosing_Scope): Return the unique defining
1682 entity when the enclosing construct is a body.
1684 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
1686 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
1687 Secondary_Stack_Size handling as a pragma is now generated for the
1688 corresponding aspect instead of an attribute. Pragma expression is
1689 relocated instead of evaluated. Discriminant of the corresponding
1690 record type is referenced rather than the type discriminant.
1691 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
1692 Secondary_Stack_Size rep item checks to only look for the pragma rep.
1693 * sem_ch13.adb (Analyze_One_Aspect): Transform
1694 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
1695 because the attribute does not have visibility on a task type's
1696 discriminants when the type's definition is expanded.
1697 (Analyze_Attribute_Definition_Clause): Remove handling of
1698 Attribute_Secondary_Stack_Size.
1699 * snames.adb-tmpl, snames.ads-tmpl: Remove
1700 Attribute_Secondary_Stack_Size, no longer used.
1702 2018-01-11 Justin Squirek <squirek@adacore.com>

1706 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1708 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
1709 individual action because the action may denote a complex expression,
1710 such as a case statement, which in turn may contain additional
1713 2018-01-11 Ed Schonberg <schonberg@adacore.com>
1715 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
1716 analysis on a copy of the expression with a copy of the index variable,
1717 because full expansion will rewrite construct into a loop with the
1718 original loop variable.
1719 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
1720 expression is an iterated component association. Full analysis takes
1721 place when construct is rewritten as a loop.
1722 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
1723 is not safe for in-place assignment.
1724 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
1725 entity with no homonym and no other entity in the scope.
1727 2018-01-11 Justin Squirek <squirek@adacore.com>
1729 * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
1730 message to be printed on the pragma argument identifier.
1732 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1734 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
1735 entity of the generated invariant procedure in order to construct a
1736 proper entity chain.
1738 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
1740 * sem_ch13.adb (Build_Predicate_Functions): Fix minor issues in
1743 2018-01-11 Arnaud Charlet <charlet@adacore.com>
1745 * einfo.ads, einfo.adb (Activation_Record_Component,
1746 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
1747 Allow E_Discriminant.
1749 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
1751 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
1752 for atomic access once the component size is taken into account and
1753 also do it if the component type is Atomic or Volatile_Full_Access.
1755 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
1757 * gnatvsn.ads: Bump copyright year.
