4 that the result will be either -infinite or +infinite.

10 Expand range of type to match the address space of the target.
11 (Task_Storage_Size): Remove unused type.
13 2018-05-25 Ed Schonberg <schonberg@adacore.com>
15 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
16 of a fixed point type and the parent is a multiplying operation,
17 resolve the operand with its own type because the context will impose a
18 resulting type on the result of the multiplication by means of
19 approriate conversion.
21 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
23 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of

25 Initialize_Scalars or Normalize_Scalars is performed with checks

54 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
55 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
56 into three distring cases rather than in one loop which attempts to
57 handle all three cases. This rewrite eliminates an issue where the last
58 frame of the stack cannot be freed, thus causing the memory range of a
59 new frame to approach the overflow point of the memory index type.
60 Since the overflow is logically treated as a
61 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
62 (SS_Allocate_Static): New routine. The routine factorizes the static
63 secondary stack-related code from the former SS_Allocate.

75 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
76 is the proper body of a subunit, the cloned body must be inserted in
77 the declarative list that contains the stub.
79 2018-05-25 Justin Squirek <squirek@adacore.com>
81 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
82 generate code for 6.5(8-10) so that we don't get an assertion error

116 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
117 Validate_Derived_Type_Instance, to verify that all interfaces
118 implemented by the formal type are also implemented by the actual. The
119 verification is complicated when an interface of the formal is declared
120 in a generic unit and the actual is declared in an instance of it.
121 There is currently no mechanism to relate an interface declared within
122 a generic to the corresponding interface in an instance, so we must
123 traverse the list of interfaces of the actual, looking for a name
124 match, and verifying that that interface is declared in an instance.
126 2018-05-25 Piotr Trojanek <trojanek@adacore.com>
128 * sem_util.adb (Iterate_Call_Parameters): Rewrite with extra

1530 as Part_Of consituents of single protected types are illegal when they
1531 take place inside a protected function.
1532 (Diagnose_Non_Variable_Lhs): Use Within_Function to check for an
1534 (Is_Protected_Part_Of_Constituent): New routine.
1535 (Within_Function): New routine.

1541 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1543 * binde.adb, par-ch6.adb, par-ch9.adb, sem_ch12.adb, sem_ch13.adb:
1546 2018-01-11 Justin Squirek <squirek@adacore.com>
1548 * par-ch6.adb (Scan_Body_Or_Expression_Function): Add additional check
1549 to make sure a given expression function is properly parenthesized.
1551 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1553 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Check the
1554 categorization of a subprogram body which does not complete a previous
1557 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1559 * sem_ch10.adb (Check_Private_Child_Unit): Ensure that the enclosing
1560 scope of package Ada is Standard.
1562 2018-01-11 Ed Schonberg <schonberg@adacore.com>
1564 * sem_ch13.adb (Replace_Type_Ref): Handle properly reference to a
1565 subcomponent of the current entity when building the body for a dynamic
1566 predicate function for a record with composite subcomponents.
1568 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1570 * exp_aggr.adb (Convert_Aggr_In_Object_Decl): Update the call to
1571 Establish_Transient_Scope.
1572 (Convert_To_Assignments): Update the call to Establish_Transient_Scope.

1574 * exp_ch6.adb (Expand_Call_Helper): Update the call to
1575 Establish_Transient_Scope.
1576 (Make_Build_In_Place_Call_In_Object_Declaration): Update the call to
1577 Establish_Transient_Scope.
1578 * exp_ch7.adb (Establish_Transient_Scope): Restructured. Delegate the
1579 management of the secondary stack to an enclosing scope if there is no
1580 suitable construct to wrap, and the transient scope was intended to
1581 manage the secondary stack.
1582 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
1583 is a valid boundary for a transient expression which comes from the
1584 statements of the alternative, otherwise alternatives cannot be
1585 wrapped. Assignments of controlled objects which have controlled
1586 actions suppressed now stop the traversal as there is no point in
1587 looking for an enclosing construct. Add several N_xxx_Body choices to
1588 the termination conditions for completeness.
1589 * exp_ch7.ads (Establish_Transient_Scope): Update the parameter profile
1590 and the associated comment on usage.
1591 * exp_smem.adb (Add_Shared_Var_Lock_Procs): Update the call to
1592 Establish_Transient_Scope.
1593 (Add_Write_After): Update the call to Establish_Transient_Scope.
1594 * sem_res.adb (Check_Initialization_Call): Removed.
1595 (Resolve_Actuals): Account for additional cases where finalization
1596 actions are required by utilizing predicate Needs_Finalization rather
1598 (Resolve_Call): Type initialization procedures can now utilize
1599 transient scopes to manage the secondary stack, thus preventing leaks
1600 during initialization. Remove the previous kludgy algorithm which
1601 attempts to manage the secondary stack at the object creation site.
1603 2018-01-11 Jerome Lambourg <lambourg@adacore.com>
1605 * libgnat/g-soliop__qnx.ads: New.

1642 * gnat_rm.texi: Regenerate.
1644 2018-01-11 Ed Schonberg <schonberg@adacore.com>
1646 * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the
1647 formsl type corresponding to the actual fixed point type is private,
1648 because in this case there can be no suspicious arithmetic operations
1649 in the generic unless they reference a formal subprogram. Clarify
1652 2018-01-11 Javier Miranda <miranda@adacore.com>
1654 * exp_util.adb (Remove_Side_Effects): No action done for functions
1655 returning class-wide types since it requires generating code using
1656 'reference and the CCG target has no secondary stack.
1657 * gnat1drv.adb: Disable building static dispatch tables when generating

1670 2018-01-11 Bob Duff <duff@adacore.com>
1672 * doc/gnat_ugn/gnat_utility_programs.rst: Rewrite gnatpp documentation
1673 to match what the Libadalang-based version does.
1674 * doc/gnat_ugn/about_this_guide.rst: Update reference.
1676 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1678 * sem_res.adb (Uses_SS): A controlled type requires the secondary stack
1679 if it contains at least one component declaration employing a function
1680 call returning on the secondary stack.
1682 2018-01-11 Yannick Moy <moy@adacore.com>

1697 2018-01-11 Ed Schonberg <schonberg@adacore.com>
1699 * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
1700 has a delayed aspect which must be processed at the point the type is
1701 frozen. This mimics what is done when the predicate is provided by a

1714 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
1716 * libgnat/s-parame*.adb, libgnat/s-parame*.ads: Remove unneeded
1717 Default_Sec_Stack_Size.
1718 * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
1719 limit check so that the integer index does not overflow. Check the
1720 dynamic stack allocation does not cause the secondary stack pointer to
1722 (SS_Info): Align colons.
1723 (SS_Init): Cover the case when bootstraping with an old compiler that
1724 does not set Default_SS_Size.
1726 2018-01-11 Ed Schonberg <schonberg@adacore.com>
1728 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
1729 legality of an inherited operation that may require overriding, ignore
1730 primitive_wrappers that correspond to explicit operations that override
1731 an interface primitive.
1732 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
1733 operation to which the class-wide expression applies is a protected op.
1734 with a primitive_wrapper, verify that the updated inherited expression
1735 does not contain an internal call to a protected function. This
1736 completes the implementation of AI12-0166.
1738 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1740 * ali.adb: Document the remaining letters available for ALI lines.
1741 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
1742 * ali.ads: Update type With_Record. Field
1743 Implicit_With_From_Instantiation is no longer in use. Add field
1745 * csinfo.adb (CSinfo): Remove the setup for attribute
1746 Implicit_With_From_Instantiation.
1747 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
1748 either implicitly or explicitly withed.
1749 (Is_Implicit_With_Clause): New routine.
1750 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
1751 confusion with the with clause attribute by the same name.
1752 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
1753 * rtsfind.adb (Maybe_Add_With): Code cleanup.
1754 * sem_ch8.adb (Present_System_Aux): Code cleanup.
1755 * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
1757 (Implicit_With_On_Parent): Mark the with clause as generated for a
1759 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
1760 instantiation are no longer marked as Implicit_With_From_Instantiation
1761 because they are already marked as implicit.
1762 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
1763 which marks implicit with clauses as related to an instantiation.
1764 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
1765 (Parent_With): New routine.
1766 (Set_Implicit_With_From_Instantiation): Removed.
1767 (Set_Parent_With): New routine.
1768 * sinfo.ads: Update the documentation of attribute Implicit_With.
1769 Remove attribute Implicit_With_From_Instantiation along with

1780 entity when the enclosing construct is a body.
1782 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
1784 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
1785 Secondary_Stack_Size handling as a pragma is now generated for the
1786 corresponding aspect instead of an attribute. Pragma expression is
1787 relocated instead of evaluated. Discriminant of the corresponding
1788 record type is referenced rather than the type discriminant.
1789 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
1790 Secondary_Stack_Size rep item checks to only look for the pragma rep.
1791 * sem_ch13.adb (Analyze_One_Aspect): Transform
1792 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
1793 because the attribute does not have visibility on a task type's
1794 discriminants when the type's definition is expanded.
1795 (Analyze_Attribute_Definition_Clause): Remove handling of
1796 Attribute_Secondary_Stack_Size.
1797 * snames.adb-tmpl, snames.ads-tmpl: Remove
1798 Attribute_Secondary_Stack_Size, no longer used.

1806 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
1807 individual action because the action may denote a complex expression,
1808 such as a case statement, which in turn may contain additional
1811 2018-01-11 Ed Schonberg <schonberg@adacore.com>
1813 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
1814 analysis on a copy of the expression with a copy of the index variable,
1815 because full expansion will rewrite construct into a loop with the
1816 original loop variable.
1817 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
1818 expression is an iterated component association. Full analysis takes
1819 place when construct is rewritten as a loop.
1820 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
1821 is not safe for in-place assignment.
1822 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
1823 entity with no homonym and no other entity in the scope.
1825 2018-01-11 Justin Squirek <squirek@adacore.com>
1827 * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
1828 message to be printed on the pragma argument identifier.
1830 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1832 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
1833 entity of the generated invariant procedure in order to construct a
1834 proper entity chain.

1843 * einfo.ads, einfo.adb (Activation_Record_Component,
1844 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
1845 Allow E_Discriminant.
1847 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
1849 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
1850 for atomic access once the component size is taken into account and
1851 also do it if the component type is Atomic or Volatile_Full_Access.
1853 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
