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

37 There is currently no mechanism to relate an interface declared within
38 a generic to the corresponding interface in an instance, so we must
39 traverse the list of interfaces of the actual, looking for a name
40 match, and verifying that that interface is declared in an instance.

1276 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
1277 delegate the secondary stack management when there is no suitable
1278 transient context, and the transient scope was intended to manage the

1283 the comment on usage.
1284 (Find_Transient_Context): Change the initinte loop into a while loop.

1290 routine Find_Transient_Context.

1560 2018-01-11 Ed Schonberg <schonberg@adacore.com>
1562 * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the
1563 formsl type corresponding to the actual fixed point type is private,
1564 because in this case there can be no suspicious arithmetic operations
1565 in the generic unless they reference a formal subprogram. Clarify

1570 * exp_util.adb (Remove_Side_Effects): No action done for functions
1571 returning class-wide types since it requires generating code using
1572 'reference and the CCG target has no secondary stack.
1573 * gnat1drv.adb: Disable building static dispatch tables when generating
1576 2018-01-11 Piotr Trojanek <trojanek@adacore.com>

1582 2018-01-11 Pascal Obry <obry@adacore.com>
1584 * libgnat/s-os_lib.adb (Normalize_Pathname): New implementation.
1586 2018-01-11 Bob Duff <duff@adacore.com>
1588 * doc/gnat_ugn/gnat_utility_programs.rst: Rewrite gnatpp documentation
1589 to match what the Libadalang-based version does.

1592 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1594 * sem_res.adb (Uses_SS): A controlled type requires the secondary stack
1595 if it contains at least one component declaration employing a function
1596 call returning on the secondary stack.

1613 2018-01-11 Ed Schonberg <schonberg@adacore.com>
1615 * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
1616 has a delayed aspect which must be processed at the point the type is
1617 frozen. This mimics what is done when the predicate is provided by a
1620 2018-01-11 Doug Rupp <rupp@adacore.com>
1622 * init.c (vxworks): Add macro checks for __aarch64__.

1633 Default_Sec_Stack_Size.
1634 * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack

1640 does not set Default_SS_Size.
1642 2018-01-11 Ed Schonberg <schonberg@adacore.com>
1644 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
1645 legality of an inherited operation that may require overriding, ignore
1646 primitive_wrappers that correspond to explicit operations that override
1647 an interface primitive.
1648 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
1649 operation to which the class-wide expression applies is a protected op.
1650 with a primitive_wrapper, verify that the updated inherited expression
1651 does not contain an internal call to a protected function. This
1652 completes the implementation of AI12-0166.
1654 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1656 * ali.adb: Document the remaining letters available for ALI lines.
1657 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
1658 * ali.ads: Update type With_Record. Field
1659 Implicit_With_From_Instantiation is no longer in use. Add field
1661 * csinfo.adb (CSinfo): Remove the setup for attribute
1662 Implicit_With_From_Instantiation.
1663 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
1664 either implicitly or explicitly withed.
1665 (Is_Implicit_With_Clause): New routine.
1666 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
1667 confusion with the with clause attribute by the same name.
1668 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
1669 * rtsfind.adb (Maybe_Add_With): Code cleanup.
1670 * sem_ch8.adb (Present_System_Aux): Code cleanup.
1671 * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
1673 (Implicit_With_On_Parent): Mark the with clause as generated for a
1675 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
1676 instantiation are no longer marked as Implicit_With_From_Instantiation
1677 because they are already marked as implicit.
1678 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
1679 which marks implicit with clauses as related to an instantiation.
1680 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
1681 (Parent_With): New routine.
1682 (Set_Implicit_With_From_Instantiation): Removed.
1683 (Set_Parent_With): New routine.
1684 * sinfo.ads: Update the documentation of attribute Implicit_With.

1695 * sem_util.adb (Find_Enclosing_Scope): Return the unique defining
1696 entity when the enclosing construct is a body.
1698 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
1700 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
1701 Secondary_Stack_Size handling as a pragma is now generated for the
1702 corresponding aspect instead of an attribute. Pragma expression is
1703 relocated instead of evaluated. Discriminant of the corresponding
1704 record type is referenced rather than the type discriminant.
1705 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
1706 Secondary_Stack_Size rep item checks to only look for the pragma rep.
1707 * sem_ch13.adb (Analyze_One_Aspect): Transform
1708 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
1709 because the attribute does not have visibility on a task type's
1710 discriminants when the type's definition is expanded.
1711 (Analyze_Attribute_Definition_Clause): Remove handling of
1712 Attribute_Secondary_Stack_Size.
1713 * snames.adb-tmpl, snames.ads-tmpl: Remove
1714 Attribute_Secondary_Stack_Size, no longer used.

1720 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1722 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
1723 individual action because the action may denote a complex expression,
1724 such as a case statement, which in turn may contain additional
1727 2018-01-11 Ed Schonberg <schonberg@adacore.com>
1729 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
1730 analysis on a copy of the expression with a copy of the index variable,
1731 because full expansion will rewrite construct into a loop with the
1732 original loop variable.
1733 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
1734 expression is an iterated component association. Full analysis takes
1735 place when construct is rewritten as a loop.
1736 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
1737 is not safe for in-place assignment.
1738 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
1739 entity with no homonym and no other entity in the scope.
1741 2018-01-11 Justin Squirek <squirek@adacore.com>
1743 * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
1744 message to be printed on the pragma argument identifier.
1746 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1748 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
1749 entity of the generated invariant procedure in order to construct a
1750 proper entity chain.

1759 * einfo.ads, einfo.adb (Activation_Record_Component,
1760 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
1761 Allow E_Discriminant.
1763 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
1765 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
1766 for atomic access once the component size is taken into account and
1767 also do it if the component type is Atomic or Volatile_Full_Access.
1769 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
1771 * gnatvsn.ads: Bump copyright year.
