(Matches_Prefixed_View_Profile): Use common predicate Conforming_Types,
rather than local Same_Formal_Type, to check whether protected operation
overrides an inherited one.
(Same_Formal_Type): New predicate, used when matching signatures of
overriding synchronized operations, to handle the case when a formal
has a type that is a generic actual.
(Is_Aliased_View): Replace check on E_Task_Type and E_Protected_Type by
predicate Is_Concurrent_Type. This ensures supportin case of subtypes.
(Needs_One_Actual): New predicate, for Ada 2005 use, to resolve

(Abstract_Interface_List): New subprogram that returns the list of

(Collect_Abstract_Interfaces): Add support for concurrent types

* sem_ch7.ads, sem_ch7.adb (Inspect_Deferred_Constant_Completion): Move

(Analyze_Package_Declaration): When the package declaration being
analyzed does not require an explicit body, call Check_Completion.
(May_Need_Implicit_Body): An implicit body is required when a package
spec contains the declaration of a remote access-to-classwide type.
(Analyze_Package_Body): If the package contains RACWs, append the
pending subprogram bodies generated by exp_dist at the end of the body.
(New_Private_Type,Unit_Requires_Body): Split Is_Abstract flag into
Is_Abstract_Subprogram and Is_Abstract_Type.

* sem_ch4.adb (Try_Primitive_Operation): The call is legal if the
prefix type is a discriminated subtype of the type of the formal.
(Analyze_Allocator): Collect all coextensions regardless of the context.
Whether they can be allocated statically is determined in exp_ch4.
(Analyze_Selected_Component): If the prefix is a limited view and the
non-limited view is available, use the non-limited one.
(Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
therefore illegal), suggest a qualified expression rather than a type
conversion, because a type conversion would be illegal in this context.
(Anayze_Allocator): Trace recursively all nested allocators so that all
coextensions are on the corresponding list for the root. Do no mark
coextensions if the root allocator is within a declaration for a stack-
allocated object, because the access discriminants will be allocated on
the stack as well.
(Analyze_Call): Remove restriction on calls to limited functions for the
cases of generic actuals for formal objects, defaults for formal objects
and defaults for record components.
(Analyze_Allocator): Before analysis, chain coextensions on the proper
element list. Their expansion is delayed until the enclosing allocator
is processed and its finalization list constructed.
(Try_Primitive_Operation): If the prefix is a concurrent type, looks
for an operation with the given name among the primitive operations of
the corresponding record type.
(Analyze_Selected_Component): If the prefix is a task type that
implements an interface, and there is no entry with the given name,
check whether there is another primitive operation (e.g. a function)
with that name.
(Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
properly the indexing of a function call written in prefix form, where
the function returns an array type, and all parameters of the function
except the first have defaults.
(Analyze_Equality_Op): If this is a call to an implicit inequality, keep
the original operands, rather than relocating them, for efficiency and
to work properly when an operand is overloaded.
(Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
(Analyze_Selected_Component): If the prefix is a private extension, only
scan the visible components, not those of the full view.
(Try_Primitive_Operation): If the operation is a procedure, collect all
possible interpretations, as for a function, because in the presence of
classwide parameters several primitive operations of the type can match
the given arguments.

* sem_ch12.adb (Check_Generic_Actuals): Use first subtype of actual
when capturing size information, instead of base type, which for a
formal array type will be the unconstrained type.
(Analyze_Formal_Object_Declaration): Add check for illegal default
expressions for a formal in object of a limited type.
(Instantiate_Object): Ditto.
(Check_Formal_Package_Instance): Skip entities that are formal objects,
because they were defaulted in the formal package and no check applies
to them.
(Check_Formal_Package_Instance): Extend conformance check to other
discrete types beyond Integer.
(Process_Default): Copy directly the unmatched formal. A generic copy
has already been performed in Analyze_Formal_Package.
(Analyze_Associations): If a formal subprogram has no match, check for
partial parametrization before looking for a default, to prevent
spurious errors.
(Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation): Do
not set the instantiation environment before analyzing the actuals.
Fixes regression on 8515-003 with implementation of AI-133.
Set_Instance_Env checks whether the generic unit is a predefined
unit, in which case the instance must be analyzed with the latest Ada
mode. This setting must take place after analysis of the actuals,
because the actuals must be analyzed and frozen in the Ada mode extant
outside of the current instantiation.
(Save_Env, Restore_Env): Preserve and restore the configuration
parameters so that predefined units can be compiled in the proper Ada
mode.
(Analyze_Formal_Object_Declaration,Analyze_Formal_Subprogram,
Instantiate_Type): Split Is_Abstract flag into Is_Abstract_Subprogram

* gnat-style.texi: Fix typo

* lib-xref.ads, lib-xref.adb:
Modify the loop that collects type references, to include interface
types that the type implements. List each of these interfaces when
building the entry for the type.
(Generate_Definition): Initialize component Def and Typ of new entry
in table Xrefs, to avoid to have these components unitialized.
(Output_References): Split Is_Abstract flag into
Is_Abstract_Subprogram and Is_Abstract_Type.
(Generate_Reference): Add barrier to do not generate the warning
associated with Ada 2005 entities with entities generated by the
expander.

* lib-writ.adb (Write_With_Lines): Factor duplicated code between the
cases where a given dependency has a body or not.
(Write_With_File_Names): New subprogram, common code for the two cases
above.

switches from previously loaded tree

* init.c: Reuse PA/HP-UX code for IA-64/HP-UX, except
__gnat_adjust_context_for_raise.
(__gnat_init_float): on x86 vxworks 5.x and 6.x, we use the same
implementation of floating point operations as native x86 targets.
So the FPU should be initialized in the same way using finit. Fix
floating point operations accuracy issues.
(__gnat_install_handler, case FreeBSD): Use proper type for sa_sigaction
member in struct sigaction, so as to avoid warning for incompatible
pointer types.
