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

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

89 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
90 Validate_Derived_Type_Instance, to verify that all interfaces
91 implemented by the formal type are also implemented by the actual. The
92 verification is complicated when an interface of the formal is declared
93 in a generic unit and the actual is declared in an instance of it.
94 There is currently no mechanism to relate an interface declared within
95 a generic to the corresponding interface in an instance, so we must
96 traverse the list of interfaces of the actual, looking for a name
97 match, and verifying that that interface is declared in an instance.
99 2018-05-25 Piotr Trojanek <trojanek@adacore.com>

1532 * sem_ch10.adb (Check_Private_Child_Unit): Ensure that the enclosing
1533 scope of package Ada is Standard.
1535 2018-01-11 Ed Schonberg <schonberg@adacore.com>
1537 * sem_ch13.adb (Replace_Type_Ref): Handle properly reference to a
1538 subcomponent of the current entity when building the body for a dynamic
1539 predicate function for a record with composite subcomponents.
1541 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1543 * exp_aggr.adb (Convert_Aggr_In_Object_Decl): Update the call to
1544 Establish_Transient_Scope.
1545 (Convert_To_Assignments): Update the call to Establish_Transient_Scope.
1546 (Expand_Array_Aggregate): Update the call to Establish_Transient_Scope.
1547 * exp_ch6.adb (Expand_Call_Helper): Update the call to
1548 Establish_Transient_Scope.
1549 (Make_Build_In_Place_Call_In_Object_Declaration): Update the call to
1550 Establish_Transient_Scope.
1551 * exp_ch7.adb (Establish_Transient_Scope): Restructured. Delegate the
1552 management of the secondary stack to an enclosing scope if there is no
1553 suitable construct to wrap, and the transient scope was intended to
1554 manage the secondary stack.
1555 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
1556 is a valid boundary for a transient expression which comes from the
1557 statements of the alternative, otherwise alternatives cannot be
1558 wrapped. Assignments of controlled objects which have controlled
1559 actions suppressed now stop the traversal as there is no point in
1560 looking for an enclosing construct. Add several N_xxx_Body choices to
1561 the termination conditions for completeness.
1562 * exp_ch7.ads (Establish_Transient_Scope): Update the parameter profile
1563 and the associated comment on usage.
1564 * exp_smem.adb (Add_Shared_Var_Lock_Procs): Update the call to
1565 Establish_Transient_Scope.
1566 (Add_Write_After): Update the call to Establish_Transient_Scope.
1567 * sem_res.adb (Check_Initialization_Call): Removed.
1568 (Resolve_Actuals): Account for additional cases where finalization
1569 actions are required by utilizing predicate Needs_Finalization rather
1571 (Resolve_Call): Type initialization procedures can now utilize
1572 transient scopes to manage the secondary stack, thus preventing leaks
1573 during initialization. Remove the previous kludgy algorithm which
1574 attempts to manage the secondary stack at the object creation site.
1576 2018-01-11 Jerome Lambourg <lambourg@adacore.com>
1578 * libgnat/g-soliop__qnx.ads: New.
1579 * adaint.c, adaint.h, cstreams.c, s-oscons-tmplt.c, sysdep.c: Update
1582 2018-01-11 Bob Duff <duff@adacore.com>

1585 a null procedure occurs in a protected definition.
1587 2018-01-11 Bob Duff <duff@adacore.com>
1589 * binderr.ads, namet.ads: Minor reformatting.
1591 2018-01-11 Bob Duff <duff@adacore.com>

1601 2018-01-11 Ed Schonberg <schonberg@adacore.com>
1603 * sem_ch6.adb (Freeze_Expr_Types): If an access value is the
1604 controlling argument of a dispatching call. freeze the corresponding
1607 2018-01-11 Ben Brosgol <brosgol@adacore.com>
1609 * doc/Makefile: Add Sphinx option -W to treat warnings as errors.
1611 2018-01-11 Ben Brosgol <brosgol@adacore.com>
1613 * doc/gnat_rm/implementation_defined_aspects.rst: Minor type/wording
1615 * gnat_rm.texi: Regenerate.
1617 2018-01-11 Ed Schonberg <schonberg@adacore.com>
1619 * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the
1620 formsl type corresponding to the actual fixed point type is private,
1621 because in this case there can be no suspicious arithmetic operations
1622 in the generic unless they reference a formal subprogram. Clarify
1625 2018-01-11 Javier Miranda <miranda@adacore.com>
1627 * exp_util.adb (Remove_Side_Effects): No action done for functions
1628 returning class-wide types since it requires generating code using
1629 'reference and the CCG target has no secondary stack.
1630 * gnat1drv.adb: Disable building static dispatch tables when generating
1633 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
1635 * libgnat/a-direio.ads, libgnat/a-sequio.ads, libgnat/a-ststio.ads,
1636 libgnat/a-textio.ads, libgnat/a-witeio.ads, libgnat/a-ztexio.ads
1637 (File_Type): Add Default_Initial_Condition aspect.
1639 2018-01-11 Pascal Obry <obry@adacore.com>
1641 * libgnat/s-os_lib.adb (Normalize_Pathname): New implementation.
1643 2018-01-11 Bob Duff <duff@adacore.com>
1645 * doc/gnat_ugn/gnat_utility_programs.rst: Rewrite gnatpp documentation
1646 to match what the Libadalang-based version does.
1647 * doc/gnat_ugn/about_this_guide.rst: Update reference.
1649 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1651 * sem_res.adb (Uses_SS): A controlled type requires the secondary stack
1652 if it contains at least one component declaration employing a function
1653 call returning on the secondary stack.
1655 2018-01-11 Yannick Moy <moy@adacore.com>
1657 * doc/gnat_rm/standard_and_implementation_defined_restrictions.rst:
1658 Update description of restriction SPARK_05 with SPARK 2014.
1659 * gnat_rm.texi: Regenerate.
1661 2018-01-11 Vasiliy Fofanov <fofanov@adacore.com>
1663 * doc/gnat_ugn/gnat_utility_programs.rst: Fix layout.
1665 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1667 * exp_aggr.adb, exp_ch9.adb, exp_util.adb, sem_aggr.adb, sem_ch3.adb,
1668 sem_res.adb, sem_util.adb: Minor reformatting.
1670 2018-01-11 Ed Schonberg <schonberg@adacore.com>
1672 * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
1673 has a delayed aspect which must be processed at the point the type is
1674 frozen. This mimics what is done when the predicate is provided by a
1677 2018-01-11 Doug Rupp <rupp@adacore.com>
1679 * init.c (vxworks): Add macro checks for __aarch64__.
1681 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1683 * exp_util.adb (Add_Failure_Expression): New routine.
1684 (Make_Predicate_Check): Reimplement the handling of Predicate_Failure.
1685 * sem_util.adb (Is_Current_Instance): Code cleanup.
1687 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
1689 * libgnat/s-parame*.adb, libgnat/s-parame*.ads: Remove unneeded
1690 Default_Sec_Stack_Size.
1691 * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
1692 limit check so that the integer index does not overflow. Check the
1693 dynamic stack allocation does not cause the secondary stack pointer to
1695 (SS_Info): Align colons.
1696 (SS_Init): Cover the case when bootstraping with an old compiler that
1697 does not set Default_SS_Size.
1699 2018-01-11 Ed Schonberg <schonberg@adacore.com>
1701 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
1702 legality of an inherited operation that may require overriding, ignore
1703 primitive_wrappers that correspond to explicit operations that override
1704 an interface primitive.
1705 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
1706 operation to which the class-wide expression applies is a protected op.
1707 with a primitive_wrapper, verify that the updated inherited expression
1708 does not contain an internal call to a protected function. This
1709 completes the implementation of AI12-0166.
1711 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1713 * ali.adb: Document the remaining letters available for ALI lines.
1714 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
1715 * ali.ads: Update type With_Record. Field
1716 Implicit_With_From_Instantiation is no longer in use. Add field
1718 * csinfo.adb (CSinfo): Remove the setup for attribute
1719 Implicit_With_From_Instantiation.
1720 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
1721 either implicitly or explicitly withed.
1722 (Is_Implicit_With_Clause): New routine.
1723 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
1724 confusion with the with clause attribute by the same name.
1725 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
1726 * rtsfind.adb (Maybe_Add_With): Code cleanup.
1727 * sem_ch8.adb (Present_System_Aux): Code cleanup.
1728 * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
1730 (Implicit_With_On_Parent): Mark the with clause as generated for a
1732 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
1733 instantiation are no longer marked as Implicit_With_From_Instantiation
1734 because they are already marked as implicit.
1735 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
1736 which marks implicit with clauses as related to an instantiation.
1737 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
1738 (Parent_With): New routine.
1739 (Set_Implicit_With_From_Instantiation): Removed.
1740 (Set_Parent_With): New routine.
1741 * sinfo.ads: Update the documentation of attribute Implicit_With.
1742 Remove attribute Implicit_With_From_Instantiation along with
1743 occurrences in nodes. Add attribute Parent_With along with occurrences
1745 (Implicit_With_From_Instantiation): Removed along with pragma Inline.
1746 (Parent_With): New routine along with pragma Inline.
1747 (Set_Implicit_With_From_Instantiation): Removed along with pragma Inline.
1748 (Set_Parent_With): New routine along with pragma Inline.
1750 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1752 * sem_util.adb (Find_Enclosing_Scope): Return the unique defining
1753 entity when the enclosing construct is a body.
1755 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
1757 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
1758 Secondary_Stack_Size handling as a pragma is now generated for the
1759 corresponding aspect instead of an attribute. Pragma expression is
1760 relocated instead of evaluated. Discriminant of the corresponding
1761 record type is referenced rather than the type discriminant.
1762 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
1763 Secondary_Stack_Size rep item checks to only look for the pragma rep.
1764 * sem_ch13.adb (Analyze_One_Aspect): Transform
1765 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
1766 because the attribute does not have visibility on a task type's
1767 discriminants when the type's definition is expanded.
1768 (Analyze_Attribute_Definition_Clause): Remove handling of
1769 Attribute_Secondary_Stack_Size.
1770 * snames.adb-tmpl, snames.ads-tmpl: Remove
1771 Attribute_Secondary_Stack_Size, no longer used.
1773 2018-01-11 Justin Squirek <squirek@adacore.com>
1775 * sem_ch8.adb: Minor comment fix.
1777 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1779 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
1780 individual action because the action may denote a complex expression,
1781 such as a case statement, which in turn may contain additional
1784 2018-01-11 Ed Schonberg <schonberg@adacore.com>
1786 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
1787 analysis on a copy of the expression with a copy of the index variable,
1788 because full expansion will rewrite construct into a loop with the
1789 original loop variable.
1790 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
1791 expression is an iterated component association. Full analysis takes
1792 place when construct is rewritten as a loop.
1793 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
1794 is not safe for in-place assignment.
1795 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
1796 entity with no homonym and no other entity in the scope.
1798 2018-01-11 Justin Squirek <squirek@adacore.com>
1800 * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
1801 message to be printed on the pragma argument identifier.
1803 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1805 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
1806 entity of the generated invariant procedure in order to construct a
1807 proper entity chain.
1809 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
1811 * sem_ch13.adb (Build_Predicate_Functions): Fix minor issues in
1814 2018-01-11 Arnaud Charlet <charlet@adacore.com>
1816 * einfo.ads, einfo.adb (Activation_Record_Component,
1817 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
1818 Allow E_Discriminant.
1820 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
1822 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
1823 for atomic access once the component size is taken into account and
1824 also do it if the component type is Atomic or Volatile_Full_Access.
1826 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
1828 * gnatvsn.ads: Bump copyright year.
