* a-rttiev.ads, a-rttiev.adb:
This is a significant redesign primarily for the sake of automatic
timer task termination but also to fix a design flaw.
Therefore we are now using an RTS lock, instead of a protected
object, to provide mutual exclusion to the queue of pending events
and the type Timing_Event is no longer a protected type.

qualification from an expression. There are numerous places where this
ought to be used, but we currently only deal properly with zero or one
level.

child unit is not within an instantiation, even though the parent
instance is on the scope stack.
(Safe_To_Capture_Value): Exclude the case of variables that are
renamings.
(Check_Obsolescent): Removed

the current value condition case.
(Has_Compatible_Alignment): New function
(Is_Dependent_Component_Of_Mutable_Object): Revise the tests for mutable
objects to handle the Ada 2005 case, where aliasedness no longer implies
that the object is constrained. In particular, for dereferenced names,

that covers abstract interface subprograms we register it in all the
secondary dispatch tables associated with abstract interfaces.

in a procedure, ensure that the queried node is a procedure
specification.

their counterparts of the renaming already impose them.
(In_Generic_Scope): New local routine to Analyze_Object_Renaming.
Determine whether an entity is inside a generic scope.
(In_Open_Scope): First pass of documentation update.
(Find_Expanded_Name): Add support for shadow entities associated with
limited withed packages. This is required to handle nested packages.
(Analyze_Package_Renaming): Remove the restriction imposed by AI-217
that makes a renaming of a limited withed package illegal.

* sem_ch7.adb (Check_Anonymous_Access_Types): New procedure, subsidiary
of Analyze_Package_Body, to create Itype references for anonymous
access types created in the package declaration, whose designated types
may have only a limited view.
(Analyze_Package_Specification): For the private part of a nested
package, install private_with_clauses of enclosing compilation unit if
we are in its visible part.
(Declare_Inherited_Private_Subprograms): Complete barrier
to ensure that the primitive operation has an alias to some parent
primitive. This is now required because, after the changes done for the
implementation of abstract interfaces, the contents of the list of
primitives has entities whose alias attribute references entities of
such list of primitives.
(Analyze_Package_Specification): Simplify code that handles parent units
of instances and formal packages.
(Uninstall_Declarations): Check the convention consistency among
primitive overriding operations of a tagged record type.

* sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
procedure cannot be a protected operation (it is a basic_declaration,
not a subprogram_declaration).
(Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
Subp. Add logic for entry processing.
(Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.
Determine whether an entry or subprogram of a protected or task type
override an inherited primitive of an implemented interface.
(New_Overloaded_Entity): Add calls to Check_Synchronized_Overriding.
Update the actual used in calls to Check_Overriding_Indicator.
(Analyze_Generic_Subprogram_Body): If the subprogram is a child unit,
generate the proper reference to the parent unit, for cross-reference.
(Analyze_Subprogram_Declaration): Protect Is_Controlling_Formal with
Is_Formal.
Add -gnatd.l --Use Ada 95 semantics for limited function returns,
(Add_Extra_Formal): Revise procedure to allow passing in associated
entity, scope, and name suffix, and handle setting of the new
Extra_Formals field.
(Create_Extra_Formals): Change existing calls to Add_Extra_Formal to
pass new parameters. Add support for adding the new extra access formal
for functions whose calls are treated as build-in-place.
(Analyze_A_Return_Statement): Correct casing in error message.
Move Pop_Scope to after Analyze_Function_Return, because an extended
return statement really is a full-fledged scope. Otherwise, visibility
doesn't work right. Correct use of "\" for continuation messages.
(Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
evilly trying to call Analyze_Object_Declaration directly. Otherwise,
the node doesn't get properly marked as analyzed.
(Analyze_Subprogram_Body): If subprogram is a function that returns
an anonymous access type that denotes a task, build a Master Entity
for it.
(Analyze_Return_Type): Add call to Null_Exclusion_Static_Checks. Verify
proper usage of null exclusion in a result definition.
(Process_Formals): Code cleanup and new error message.
(Process_Formals): Detect incorrect application of null exclusion to
non-access types.
(Conforming_Types): Handle conformance between [sub]types and itypes
generated for entities that have null exclusions applied to them.
(Maybe_Primitive_Operation): Add an additional type retrieval when the
base type is an access subtype. This case arrises with null exclusions.
(New_Overloaded_Entity): Do not remove the overriden entity from the
homonym chain if it corresponds with an abstract interface primitive.
(Process_Formals): Replace membership test agains Incomplete_Kind with a
call to the synthesized predicate Is_Incomplete_Type.
(Analyze_Subprogram_Body): Check wrong placement of abstract interface
primitives.
(Analyze_Subprogram_Declaration): Check that abstract interface
primitives are abstract or null.
(Analyze_Subprogram_Specification): Remove previous check for abstract
interfaces because it was not complete.
(Has_Interface_Formals): Removed.

(Analyze_Assignment_Statement): Call Warn_On_Useless_Assignment
(Process_Bounds): If the bounds are integer literals that result from
constant-folding, and they carry a user-defined type, preserve that type
rather than treating this as an integer range.
(Analyze_Exit_Statement): Test for E_Return_Statement in legality check.
(Analyze_Goto_Statement): Test for E_Return_Stateemnt in legality check.
(Analyze_Assignment_Statement): Add call to Check_Elab_Assign for
left hand side of assignment.

* sem_ch4.adb (Try_Primitive_Operation): Code cleanup to ensure that we
generate the same errors compiling under -gnatc.
(Try_Object_Operation): If no candidate interpretation succeeds, but
there is at least one primitive operation with the right name, report
error in call rather than on a malformed selected component.
(Analyze_Selected_Component): If the prefix is an incomplete type from
a limited view, and the full view is available, use the full view to
determine whether this is a prefixed call to a primitive operation.
(Operator_Check): Verify that a candidate interpretation is a binary
operation before checking the type of its second formal.
(Analyze_Call): Add additional warnings for function call contexts not
yet supported.
(Analyze_Allocator): Move the check for "initialization not allowed for
limited types" after analyzing the expression. This is necessary,
because OK_For_Limited_Init looks at the structure of the expression.
Before analysis, we don't necessarily know what sort of expression it
is. For example, we don't know whether F(X) is a function call or an
indexed component; the former is legal in Ada 2005; the latter is not.
(Analyze_Allocator): Correct code for AI-287 -- extension aggregates
were missing. We also didn't handle qualified expressions. Now also
allow function calls. Use new common routine OK_For_Limited_Init.
(Analyze_Type_Conversion): Do not perform some legality checks in an
instance, because the error message will be redundant or spurious.
(Analyze_Overloaded_Selected_Component): Do not do style check when
setting an entity, since we do not know it is the right entity yet.
(Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
(Analyze_Overloaded_Selected_Component): Same change
(Analyze_Selected_Component): Remove unnecessary prefix type retrieval
since regular incomplete subtypes are transformed into corresponding
subtypes of their full views.
(Complete_Object_Operation): Treat name of transformed subprogram call
as coming from source, for browsing purposes.
(Try_Primitive_Operation): If formal is an access parameter, compare
with base type of object to determine whether it is a primitive
operation.
(Operator_Check): If no interpretation of the operator matches, check
whether a use clause on any candidate might make the operation legal.
(Try_Class_Wide_Operation): Check whether the first parameter is an
access type whose designated type is class-wide.

as defined by 8.3(23) as amended by AI-195.
(New_Stream_Subprogram): New procedure, factoring behaviour from both
New_Stream_Function and New_Stream_Procedure.

* sem_ch12.ads, sem_ch12.adb (Save_References): If node is an operator
that has been constant-folded, preserve information of original tree,
for ASIS uses.
(Analyze_Formal_Derived_Type): Set the limited present flag of the newly
generated private extension declaration if the formal derived type is
synchronized. Carry synchronized present over to the generated private
extension.
(Validate_Derived_Type_Instance): Ensure that the actual of a
synchronized formal derived type is a synchronized tagged type.
(Instantiate_Formal_Package): When creating the instantiation used to
validate the actual package of a formal declared without a box, check
whether the formal itself depends on a prior actual.
(Instantiate_Formal_Subprogram): Create new entities for the defining
identifiers of the formals in the renaming declaration, for ASIS use.
(Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
a renaming declaration or a subtype declaration for an actual in an
instance, capture location information of declaration in generic, for
ASIS use.
(Instantiate_Formal_Package): Add comments on needed additional tests.
AI-317 (partial parametrization) is fully implemented.
(Validate_Private_Type_Instance): Add check for actual which
must have preelaborable initialization
Use new // insertion for some continuation messages
(Analyze_Formal_Object_Declaration): Change usage of Expression to
Default_Expression. Add type retrieval when the declaration has an
access definition. Update premature usage of incomplete type check.
(Check_Access_Definition): New subsidiary routine. Check whether the
current compilation version is Ada 05 and the supplied node has an
access definition.
(Instantiate object): Alphabetize local variables. Handle the creation
of new renaming declarations with respect to the kind of definition
used - either an access definition or a subtype mark. Guard against
unnecessary error message in the context of anonymous access types after
they have been resolved. Add check for required null exclusion in a
formal object declaration.
(Switch_View): A private subtype of a non-private type needs to be
switched (the base type can have been switched without its private
dependents because of the last branch of Check_Private_View.
(Check_Private_View): Do not recompute Base_Type (T), instead use cached
value from BT.
(Instantiate_Type): Emit an error message whenever a class-wide type of
a tagged incomplete type is used as a generic actual.
(Find_Actual_Type): Extend routine to handle a component type in a child
unit that is imported from a formal package in a parent.
(Validate_Derived_Type_Instance): Check that analyzed formal and actual
agree on constrainedness, rather than checking against ultimate ancestor
(Instantiate_Subprogram_Body): Create a cross-reference link to the
generic body, for navigation purposes.

properly an attempt to apply Unchecked_Access to a protected operation.
(OK_Self_Reference): New subprogram to check the legality of an access
attribute whose prefix is the type of an enclosing aggregate.
Generalizes previous mechanism to handle attribute references nested
arbitrarily deep within the aggregate.
(Analyze_Access_Attribute): An access attribute whose prefix is a type
can appear in an aggregate if this is a default-initialized aggregate
for a self-referential type.
(Resolve_Attribute, case Access): Ditto.
Add support for new implementation defined attribute Stub_Type.
(Eval_Attribute, case Attribute_Stub_Type): New case.

Has_Specified_Stream_Attribute flag.
Disallow Storage_Size and Storage_Pool for access to subprogram
(Resolve_Attribute, case 'Access et al): Take into account anonymous
access types of return subtypes in extended return statements. Remove
accessibility checks on anonymous access types when Unchecked_Access is
used.
(Analyze_Attribute): Add support for the use of 'Class to convert
a class-wide interface to a tagged type.
Add support for the attribute Priority.
(Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
whether the designated type is discriminated with a constrained partial
view and require static matching in that case.
Add local variable Des_Btyp. The Designated_Type
of an access to incomplete subtype is either its non-limited view if
coming from a limited with or its etype if regular incomplete subtype.
* sem_cat.ads, sem_cat.adb (Validate_Remote_Access_To_Class_Wide_Type):
Fix predicate to identify and allow cases of (expander-generated)
references to tag of designated object of a RACW.
(Validate_Static_Object_Name): In Ada 2005, a formal object is
non-static, and therefore cannot appear as a primary in a preelaborable
package.

Has_Read_Write_Attributes.
(Has_Read_Write_Attributes): Reimplement in termes of

for P.Q then a with_clause for P in the same body is not redundant,
even if the spec also has a with_clause on P.
Add missing continuation mark to error msg
(Build_Limited_Views): A limited view of a type is tagged if its
declaration includes a record extension.
(Analyze_Proper_Body): Set Corresponding_Stub field in N_Subunit
node, even if the subunit has errors. This avoids malfunction by
Lib.Check_Same_Extended_Unit in the presence of syntax errors.
(Analyze_Compilation_Unit): Add circuit to make sure we get proper
generation of obsolescent messages for with statements (cannot do
this too early, or we cannot implement avoiding the messages in the
case of obsolescent units withing obsolescent units).
(Install_Siblings): If the with_clause is on a remote descendant of
an ancestor of the current compilation unit, find whether there is
a sibling child unit that is immediately visible.
(Remove_Private_With_Clauses): New procedure, invoked after completing
the analysis of the private part of a nested package, to remove from
visibility the private with_clauses of the enclosing package
declaration.
(Analyze_With_Clause): Remove Check_Obsolescent call, this checking is
now centralized in Generate_Reference.
(Install_Limited_Context_Clauses): Remove superfluous error
message associated with unlimited view visible through use
and renamings. In addition, at the point in which the error
is reported, we add the backslash to the text of the error
to ensure that it is reported as a single error message.
Use new // insertion for some continuation messages
(Expand_Limited_With_Clause): Use copy of name rather than name itself,
to create implicit with_clause for parent unit mentioned in original
limited_with_clause.
(Install_Limited_With_Unit): Set entity of parent identifiers if the
unit is a child unit. For ASIS queries.
(Analyze_Subunit): If the subunit appears within a child unit, make all
ancestor child units directly visible again.

* Makefile.in: Set EH mechanism to ZCX for FreeBSD.
(NO_REORDER_ADAFLAGS): New var defined to -fno-toplevel-reorder if
possible.
(a-except.o): Pass it to the compiler.
(gnatlib-shared-vms): Removed -nostartfiles switch in link step.
(LIBGNAT_TARGET_PAIRS for Windows): Avoid the use of the specific
a-calend-mingw.adb version.
* Makefile.rtl: Added s-dsaser.
Add object entries for Ada.Calendar.[Arithmetic/Formatting/Time_Zones]
(GNATRTL_TASKING_OBJS): Add Ada.Dispatching and
Ada.Dispatching.Round_Robin.
Added new unit Ada.Containers.Restricted_Bounded_Doubly_Linked_Lists
* Make-lang.in: Remove all references to gt-ada-decl.h.
Add concatenation (s-strops/s-sopco3/s-sopco4/s-sopco5) to compiler
sources.
Add dependency on ada/s-restri.o for GNAT1 and GNATBIND objects.
Update dependencies.
* system-freebsd-x86.ads: Make ZCX the default EH mechanism for FreeBSD

* lib-load.adb (Load_Unit): Skip the test for a unit not found when
its file has already been loaded, according to the unit being loaded,
not to the current value of Multiple_Unit_Index.

* layout.adb (Layout_Record_Type): Deal with non-static subtypes of
variant records
(Layout_Variant_Record): Retrieve the discriminants from the entity
rather than from the type definition, because in the case of a full
type for a private type we need to take the discriminants from the
partial view.
(Layout_Component_List): When applying the Max operator to variants with
a nonstatic size, check whether either operand is static and scale that
operand from bits to storage units before applying Max.
(Layout_Type): In VMS, if a C-convention access type has no explicit
size clause (and does not inherit one in the case of a derived type),
then the size is reset to 32 from 64.
