1058 (Unit_Entity): New routine.
1059 * sem_prag.adb (Analyze_Pragma): Reimplement the handling of pragma
1060 Elaboration_Checks. The analysis now ensures that the pragma appears at
1061 the configuration level, and on the initial declaration of a unit.
1062 Other placements are either flagged as illegal, or ignored.

1180 2018-05-21 Hristian Kirtchev <kirtchev@adacore.com>
1182 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
1183 delegate the secondary stack management when there is no suitable
1184 transient context, and the transient scope was intended to manage the

1186 transient scope creation logic by special casing assignment statements
1187 of controlled components for type initialization procedures.
1188 (Find_Node_To_Be_Wrapped): Renamed to Find_Transient_Context. Update
1189 the comment on usage.
1190 (Find_Transient_Context): Change the initinte loop into a while loop.

1192 contexts because they rely on special processing. Assignment statements
1193 are now treated as a normal transient context, special cases are
1194 handled by the caller. Add special processing for pragma Check.

1196 routine Find_Transient_Context.
1197 * sem_ch5.adb (Check_Call): Reimplemented. Add code to properly

1405 is a valid boundary for a transient expression which comes from the

1418 actions are required by utilizing predicate Needs_Finalization rather
1420 (Resolve_Call): Type initialization procedures can now utilize
1421 transient scopes to manage the secondary stack, thus preventing leaks
1422 during initialization. Remove the previous kludgy algorithm which
1423 attempts to manage the secondary stack at the object creation site.

1544 (SS_Info): Align colons.
1545 (SS_Init): Cover the case when bootstraping with an old compiler that
1546 does not set Default_SS_Size.
1548 2018-01-11 Ed Schonberg <schonberg@adacore.com>
1550 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
1551 legality of an inherited operation that may require overriding, ignore
1552 primitive_wrappers that correspond to explicit operations that override
1553 an interface primitive.
1554 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
1555 operation to which the class-wide expression applies is a protected op.
1556 with a primitive_wrapper, verify that the updated inherited expression
1557 does not contain an internal call to a protected function. This
1558 completes the implementation of AI12-0166.
1560 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1562 * ali.adb: Document the remaining letters available for ALI lines.
1563 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
1564 * ali.ads: Update type With_Record. Field
1565 Implicit_With_From_Instantiation is no longer in use. Add field
1567 * csinfo.adb (CSinfo): Remove the setup for attribute
1568 Implicit_With_From_Instantiation.
1569 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
1570 either implicitly or explicitly withed.
1571 (Is_Implicit_With_Clause): New routine.
1572 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
1573 confusion with the with clause attribute by the same name.
1574 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
1575 * rtsfind.adb (Maybe_Add_With): Code cleanup.
1576 * sem_ch8.adb (Present_System_Aux): Code cleanup.
1577 * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
1579 (Implicit_With_On_Parent): Mark the with clause as generated for a
1581 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
1582 instantiation are no longer marked as Implicit_With_From_Instantiation
1583 because they are already marked as implicit.
1584 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
1585 which marks implicit with clauses as related to an instantiation.
1586 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
1587 (Parent_With): New routine.
1588 (Set_Implicit_With_From_Instantiation): Removed.
1589 (Set_Parent_With): New routine.
1590 * sinfo.ads: Update the documentation of attribute Implicit_With.
1591 Remove attribute Implicit_With_From_Instantiation along with
1592 occurrences in nodes. Add attribute Parent_With along with occurrences
1594 (Implicit_With_From_Instantiation): Removed along with pragma Inline.
1595 (Parent_With): New routine along with pragma Inline.
1596 (Set_Implicit_With_From_Instantiation): Removed along with pragma Inline.
1597 (Set_Parent_With): New routine along with pragma Inline.
1599 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1601 * sem_util.adb (Find_Enclosing_Scope): Return the unique defining
1602 entity when the enclosing construct is a body.
1604 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
1606 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
1607 Secondary_Stack_Size handling as a pragma is now generated for the
1608 corresponding aspect instead of an attribute. Pragma expression is
1609 relocated instead of evaluated. Discriminant of the corresponding
1610 record type is referenced rather than the type discriminant.
1611 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
1612 Secondary_Stack_Size rep item checks to only look for the pragma rep.
1613 * sem_ch13.adb (Analyze_One_Aspect): Transform
1614 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
1615 because the attribute does not have visibility on a task type's
1616 discriminants when the type's definition is expanded.
1617 (Analyze_Attribute_Definition_Clause): Remove handling of
1618 Attribute_Secondary_Stack_Size.
1619 * snames.adb-tmpl, snames.ads-tmpl: Remove
1620 Attribute_Secondary_Stack_Size, no longer used.
1622 2018-01-11 Justin Squirek <squirek@adacore.com>
1624 * sem_ch8.adb: Minor comment fix.
1626 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1628 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
1629 individual action because the action may denote a complex expression,
1630 such as a case statement, which in turn may contain additional
1633 2018-01-11 Ed Schonberg <schonberg@adacore.com>
1635 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
1636 analysis on a copy of the expression with a copy of the index variable,
1637 because full expansion will rewrite construct into a loop with the
1638 original loop variable.
1639 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
1640 expression is an iterated component association. Full analysis takes
1641 place when construct is rewritten as a loop.
1642 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
1643 is not safe for in-place assignment.
1644 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
1645 entity with no homonym and no other entity in the scope.
1647 2018-01-11 Justin Squirek <squirek@adacore.com>
1649 * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
1650 message to be printed on the pragma argument identifier.
1652 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1654 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
1655 entity of the generated invariant procedure in order to construct a
1656 proper entity chain.
1658 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
1660 * sem_ch13.adb (Build_Predicate_Functions): Fix minor issues in
1663 2018-01-11 Arnaud Charlet <charlet@adacore.com>
1665 * einfo.ads, einfo.adb (Activation_Record_Component,
1666 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
1667 Allow E_Discriminant.
1669 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
1671 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
1672 for atomic access once the component size is taken into account and
1673 also do it if the component type is Atomic or Volatile_Full_Access.
1675 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
1677 * gnatvsn.ads: Bump copyright year.
1679 2018-01-03 Richard Sandiford <richard.sandiford@linaro.org>
1680 Alan Hayward <alan.hayward@arm.com>
1681 David Sherwood <david.sherwood@arm.com>
1683 * gcc-interface/misc.c (enumerate_modes): Treat GET_MODE_BITSIZE

1687 Alan Hayward <alan.hayward@arm.com>
1688 David Sherwood <david.sherwood@arm.com>

1694 Alan Hayward <alan.hayward@arm.com>
1695 David Sherwood <david.sherwood@arm.com>
1697 * gcc-interface/utils.c (gnat_types_compatible_p): Handle
1698 polynomial TYPE_VECTOR_SUBPARTS.
1700 2018-01-03 Richard Sandiford <richard.sandiford@linaro.org>
1701 Alan Hayward <alan.hayward@arm.com>
1702 David Sherwood <david.sherwood@arm.com>

1707 2018-01-03 Jakub Jelinek <jakub@redhat.com>
1709 Update copyright years.
1711 * gnat_ugn.texi: Bump @copying's copyright year.
