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

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

1291 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
1292 delegate the secondary stack management when there is no suitable
1293 transient context, and the transient scope was intended to manage the

1298 the comment on usage.
1299 (Find_Transient_Context): Change the initinte loop into a while loop.

1527 actions are required by utilizing predicate Needs_Finalization rather
1529 (Resolve_Call): Type initialization procedures can now utilize
1530 transient scopes to manage the secondary stack, thus preventing leaks
1531 during initialization. Remove the previous kludgy algorithm which
1532 attempts to manage the secondary stack at the object creation site.

1573 * gnat_rm.texi: Regenerate.
1575 2018-01-11 Ed Schonberg <schonberg@adacore.com>
1577 * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the
1578 formsl type corresponding to the actual fixed point type is private,
1579 because in this case there can be no suspicious arithmetic operations
1580 in the generic unless they reference a formal subprogram. Clarify
1583 2018-01-11 Javier Miranda <miranda@adacore.com>
1585 * exp_util.adb (Remove_Side_Effects): No action done for functions
1586 returning class-wide types since it requires generating code using
1587 'reference and the CCG target has no secondary stack.
1588 * gnat1drv.adb: Disable building static dispatch tables when generating
1591 2018-01-11 Piotr Trojanek <trojanek@adacore.com>

1597 2018-01-11 Pascal Obry <obry@adacore.com>
1599 * libgnat/s-os_lib.adb (Normalize_Pathname): New implementation.
1601 2018-01-11 Bob Duff <duff@adacore.com>
1603 * doc/gnat_ugn/gnat_utility_programs.rst: Rewrite gnatpp documentation
1604 to match what the Libadalang-based version does.

1607 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1609 * sem_res.adb (Uses_SS): A controlled type requires the secondary stack
1610 if it contains at least one component declaration employing a function
1611 call returning on the secondary stack.

1628 2018-01-11 Ed Schonberg <schonberg@adacore.com>
1630 * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
1631 has a delayed aspect which must be processed at the point the type is
1632 frozen. This mimics what is done when the predicate is provided by a
1635 2018-01-11 Doug Rupp <rupp@adacore.com>
1637 * init.c (vxworks): Add macro checks for __aarch64__.

1648 Default_Sec_Stack_Size.
1649 * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack

1653 (SS_Info): Align colons.
1654 (SS_Init): Cover the case when bootstraping with an old compiler that
1655 does not set Default_SS_Size.
1657 2018-01-11 Ed Schonberg <schonberg@adacore.com>
1659 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
1660 legality of an inherited operation that may require overriding, ignore
1661 primitive_wrappers that correspond to explicit operations that override
1662 an interface primitive.
1663 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
1664 operation to which the class-wide expression applies is a protected op.
1665 with a primitive_wrapper, verify that the updated inherited expression
1666 does not contain an internal call to a protected function. This
1667 completes the implementation of AI12-0166.
1669 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1671 * ali.adb: Document the remaining letters available for ALI lines.
1672 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
1673 * ali.ads: Update type With_Record. Field
1674 Implicit_With_From_Instantiation is no longer in use. Add field
1676 * csinfo.adb (CSinfo): Remove the setup for attribute
1677 Implicit_With_From_Instantiation.
1678 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
1679 either implicitly or explicitly withed.
1680 (Is_Implicit_With_Clause): New routine.
1681 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
1682 confusion with the with clause attribute by the same name.
1683 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
1684 * rtsfind.adb (Maybe_Add_With): Code cleanup.
1685 * sem_ch8.adb (Present_System_Aux): Code cleanup.

1688 (Implicit_With_On_Parent): Mark the with clause as generated for a
1690 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
1691 instantiation are no longer marked as Implicit_With_From_Instantiation
1692 because they are already marked as implicit.
1693 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
1694 which marks implicit with clauses as related to an instantiation.
1695 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
1696 (Parent_With): New routine.
1697 (Set_Implicit_With_From_Instantiation): Removed.
1698 (Set_Parent_With): New routine.

1710 * sem_util.adb (Find_Enclosing_Scope): Return the unique defining
1711 entity when the enclosing construct is a body.
1713 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
1715 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
1716 Secondary_Stack_Size handling as a pragma is now generated for the
1717 corresponding aspect instead of an attribute. Pragma expression is
1718 relocated instead of evaluated. Discriminant of the corresponding
1719 record type is referenced rather than the type discriminant.
1720 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
1721 Secondary_Stack_Size rep item checks to only look for the pragma rep.
1722 * sem_ch13.adb (Analyze_One_Aspect): Transform
1723 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
1724 because the attribute does not have visibility on a task type's
1725 discriminants when the type's definition is expanded.
1726 (Analyze_Attribute_Definition_Clause): Remove handling of
1727 Attribute_Secondary_Stack_Size.
1728 * snames.adb-tmpl, snames.ads-tmpl: Remove
1729 Attribute_Secondary_Stack_Size, no longer used.

1735 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1737 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
1738 individual action because the action may denote a complex expression,
1739 such as a case statement, which in turn may contain additional
1742 2018-01-11 Ed Schonberg <schonberg@adacore.com>
1744 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
1745 analysis on a copy of the expression with a copy of the index variable,
1746 because full expansion will rewrite construct into a loop with the
1747 original loop variable.
1748 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
1749 expression is an iterated component association. Full analysis takes
1750 place when construct is rewritten as a loop.
1751 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
1752 is not safe for in-place assignment.
1753 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
1754 entity with no homonym and no other entity in the scope.
1756 2018-01-11 Justin Squirek <squirek@adacore.com>
1758 * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
1759 message to be printed on the pragma argument identifier.
1761 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1763 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
1764 entity of the generated invariant procedure in order to construct a
1765 proper entity chain.
1767 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
1769 * sem_ch13.adb (Build_Predicate_Functions): Fix minor issues in

1774 * einfo.ads, einfo.adb (Activation_Record_Component,
1775 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
1776 Allow E_Discriminant.
1778 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
1780 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
1781 for atomic access once the component size is taken into account and
1782 also do it if the component type is Atomic or Volatile_Full_Access.
1784 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
1786 * gnatvsn.ads: Bump copyright year.
