9 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
11 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
12 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
13 into three distring cases rather than in one loop which attempts to
14 handle all three cases. This rewrite eliminates an issue where the last
15 frame of the stack cannot be freed, thus causing the memory range of a
16 new frame to approach the overflow point of the memory index type.
17 Since the overflow is logically treated as a
18 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
19 (SS_Allocate_Static): New routine. The routine factorizes the static
20 secondary stack-related code from the former SS_Allocate.

33 is the proper body of a subunit, the cloned body must be inserted in
34 the declarative list that contains the stub.

73 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
74 Validate_Derived_Type_Instance, to verify that all interfaces
75 implemented by the formal type are also implemented by the actual. The
76 verification is complicated when an interface of the formal is declared
77 in a generic unit and the actual is declared in an instance of it.
78 There is currently no mechanism to relate an interface declared within
79 a generic to the corresponding interface in an instance, so we must
80 traverse the list of interfaces of the actual, looking for a name
81 match, and verifying that that interface is declared in an instance.
83 2018-05-25 Piotr Trojanek <trojanek@adacore.com>
85 * sem_util.adb (Iterate_Call_Parameters): Rewrite with extra

1531 * exp_ch6.adb (Expand_Call_Helper): Update the call to
1532 Establish_Transient_Scope.
1533 (Make_Build_In_Place_Call_In_Object_Declaration): Update the call to
1534 Establish_Transient_Scope.
1535 * exp_ch7.adb (Establish_Transient_Scope): Restructured. Delegate the
1536 management of the secondary stack to an enclosing scope if there is no
1537 suitable construct to wrap, and the transient scope was intended to
1538 manage the secondary stack.
1539 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
1540 is a valid boundary for a transient expression which comes from the
1541 statements of the alternative, otherwise alternatives cannot be
1542 wrapped. Assignments of controlled objects which have controlled
1543 actions suppressed now stop the traversal as there is no point in
1544 looking for an enclosing construct. Add several N_xxx_Body choices to
1545 the termination conditions for completeness.
1546 * exp_ch7.ads (Establish_Transient_Scope): Update the parameter profile
1547 and the associated comment on usage.
1548 * exp_smem.adb (Add_Shared_Var_Lock_Procs): Update the call to
1549 Establish_Transient_Scope.
1550 (Add_Write_After): Update the call to Establish_Transient_Scope.
1551 * sem_res.adb (Check_Initialization_Call): Removed.
1552 (Resolve_Actuals): Account for additional cases where finalization
1553 actions are required by utilizing predicate Needs_Finalization rather
1555 (Resolve_Call): Type initialization procedures can now utilize
1556 transient scopes to manage the secondary stack, thus preventing leaks
1557 during initialization. Remove the previous kludgy algorithm which
1558 attempts to manage the secondary stack at the object creation site.
1560 2018-01-11 Jerome Lambourg <lambourg@adacore.com>
1562 * libgnat/g-soliop__qnx.ads: New.

1599 * gnat_rm.texi: Regenerate.
1601 2018-01-11 Ed Schonberg <schonberg@adacore.com>
1603 * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the
1604 formsl type corresponding to the actual fixed point type is private,
1605 because in this case there can be no suspicious arithmetic operations
1606 in the generic unless they reference a formal subprogram. Clarify
1609 2018-01-11 Javier Miranda <miranda@adacore.com>
1611 * exp_util.adb (Remove_Side_Effects): No action done for functions
1612 returning class-wide types since it requires generating code using
1613 'reference and the CCG target has no secondary stack.
1614 * gnat1drv.adb: Disable building static dispatch tables when generating
1617 2018-01-11 Piotr Trojanek <trojanek@adacore.com>

1621 (File_Type): Add Default_Initial_Condition aspect.
1623 2018-01-11 Pascal Obry <obry@adacore.com>
1625 * libgnat/s-os_lib.adb (Normalize_Pathname): New implementation.
1627 2018-01-11 Bob Duff <duff@adacore.com>
1629 * doc/gnat_ugn/gnat_utility_programs.rst: Rewrite gnatpp documentation
1630 to match what the Libadalang-based version does.
1631 * doc/gnat_ugn/about_this_guide.rst: Update reference.
1633 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1635 * sem_res.adb (Uses_SS): A controlled type requires the secondary stack
1636 if it contains at least one component declaration employing a function
1637 call returning on the secondary stack.
1639 2018-01-11 Yannick Moy <moy@adacore.com>
1641 * doc/gnat_rm/standard_and_implementation_defined_restrictions.rst:

1651 * exp_aggr.adb, exp_ch9.adb, exp_util.adb, sem_aggr.adb, sem_ch3.adb,
1652 sem_res.adb, sem_util.adb: Minor reformatting.
1654 2018-01-11 Ed Schonberg <schonberg@adacore.com>
1656 * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
1657 has a delayed aspect which must be processed at the point the type is
1658 frozen. This mimics what is done when the predicate is provided by a
1661 2018-01-11 Doug Rupp <rupp@adacore.com>
1663 * init.c (vxworks): Add macro checks for __aarch64__.
1665 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>

1669 * sem_util.adb (Is_Current_Instance): Code cleanup.
1671 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
1673 * libgnat/s-parame*.adb, libgnat/s-parame*.ads: Remove unneeded
1674 Default_Sec_Stack_Size.
1675 * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
1676 limit check so that the integer index does not overflow. Check the
1677 dynamic stack allocation does not cause the secondary stack pointer to
1679 (SS_Info): Align colons.
1680 (SS_Init): Cover the case when bootstraping with an old compiler that
1681 does not set Default_SS_Size.
1683 2018-01-11 Ed Schonberg <schonberg@adacore.com>
1685 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
1686 legality of an inherited operation that may require overriding, ignore
1687 primitive_wrappers that correspond to explicit operations that override
1688 an interface primitive.
1689 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
1690 operation to which the class-wide expression applies is a protected op.
1691 with a primitive_wrapper, verify that the updated inherited expression
1692 does not contain an internal call to a protected function. This
1693 completes the implementation of AI12-0166.
1695 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1697 * ali.adb: Document the remaining letters available for ALI lines.
1698 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
1699 * ali.ads: Update type With_Record. Field
1700 Implicit_With_From_Instantiation is no longer in use. Add field
1702 * csinfo.adb (CSinfo): Remove the setup for attribute
1703 Implicit_With_From_Instantiation.
1704 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
1705 either implicitly or explicitly withed.
1706 (Is_Implicit_With_Clause): New routine.
1707 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
1708 confusion with the with clause attribute by the same name.
1709 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
1710 * rtsfind.adb (Maybe_Add_With): Code cleanup.
1711 * sem_ch8.adb (Present_System_Aux): Code cleanup.
1712 * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
1714 (Implicit_With_On_Parent): Mark the with clause as generated for a
1716 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
1717 instantiation are no longer marked as Implicit_With_From_Instantiation
1718 because they are already marked as implicit.
1719 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
1720 which marks implicit with clauses as related to an instantiation.
1721 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
1722 (Parent_With): New routine.
1723 (Set_Implicit_With_From_Instantiation): Removed.
1724 (Set_Parent_With): New routine.
1725 * sinfo.ads: Update the documentation of attribute Implicit_With.
1726 Remove attribute Implicit_With_From_Instantiation along with
1727 occurrences in nodes. Add attribute Parent_With along with occurrences

1736 * sem_util.adb (Find_Enclosing_Scope): Return the unique defining
1737 entity when the enclosing construct is a body.
1739 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
1741 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
1742 Secondary_Stack_Size handling as a pragma is now generated for the
1743 corresponding aspect instead of an attribute. Pragma expression is
1744 relocated instead of evaluated. Discriminant of the corresponding
1745 record type is referenced rather than the type discriminant.
1746 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
1747 Secondary_Stack_Size rep item checks to only look for the pragma rep.
1748 * sem_ch13.adb (Analyze_One_Aspect): Transform
1749 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
1750 because the attribute does not have visibility on a task type's
1751 discriminants when the type's definition is expanded.
1752 (Analyze_Attribute_Definition_Clause): Remove handling of
1753 Attribute_Secondary_Stack_Size.
1754 * snames.adb-tmpl, snames.ads-tmpl: Remove
1755 Attribute_Secondary_Stack_Size, no longer used.

1761 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1763 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
1764 individual action because the action may denote a complex expression,
1765 such as a case statement, which in turn may contain additional
1768 2018-01-11 Ed Schonberg <schonberg@adacore.com>
1770 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
1771 analysis on a copy of the expression with a copy of the index variable,
1772 because full expansion will rewrite construct into a loop with the
1773 original loop variable.
1774 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
1775 expression is an iterated component association. Full analysis takes
1776 place when construct is rewritten as a loop.
1777 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
1778 is not safe for in-place assignment.
1779 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
1780 entity with no homonym and no other entity in the scope.
1782 2018-01-11 Justin Squirek <squirek@adacore.com>
1784 * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
1785 message to be printed on the pragma argument identifier.
1787 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1789 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
1790 entity of the generated invariant procedure in order to construct a
1791 proper entity chain.
1793 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
1795 * sem_ch13.adb (Build_Predicate_Functions): Fix minor issues in

1800 * einfo.ads, einfo.adb (Activation_Record_Component,
1801 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
1802 Allow E_Discriminant.
1804 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
1806 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
1807 for atomic access once the component size is taken into account and
1808 also do it if the component type is Atomic or Volatile_Full_Access.
1810 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
