a Character or Wide_Character type, set the flag TYPE_STRING_FLAG,
so that debug writers can distinguish it from ordinary integers.

safety test to make sure no alignment is set to a smaller value than
the alignment of the field type.

non dummy GCC tree for a Concurrent_Record_Type, as it might
legitimately have been elaborated while processing the associated
Concurrent_Type prior to this explicit freeze node.
(Identifier_to_gnu): Do not make a variable referenced in a SJLJ
exception handler volatile if it is of variable size.
(process_type): Remove bypass for types coming from a limited_with
clause.

actual, convert the corresponding gnu_actual to the real destination
type when necessary.
(add_decl_expr): Set the DECL_READONLY_ONCE_ELAB flag on variables
originally TREE_READONLY but whose elaboration cannot be performed
statically.

(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.

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

(Analyze_Allocator): Move the check for "initialization not allowed for

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.

* g-awk.ads: Use overloaded subprograms in every case where we used to
have a default of Current_Session. This makes the code closer to be
correct for both Ada 95 and 2005.

N_Extended_Return_Statement and N_Return_Object_Declaration.
* sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
type is in the same category as type of context before applying check,
to prevent anomalies in instantiations.
(Resolve_Aggregate): Remove test for limited components in aggregates.
It's unnecessary in Ada 95, because if it has limited components, then
it must be limited. It's wrong in Ada 2005, because limited aggregates
are now allowed.
(Resolve_Record_Aggregate): Move check for limited types later, because
OK_For_Limited_Init requires its argument to have been resolved.
(Get_Value): When copying the component default expression for a
defaulted association in an aggregate, use the sloc of the aggregate
and not that of the original expression, to prevent spurious
elaboration errors, when the expression includes function calls.
(Check_Non_Limited_Type): 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.

with space can upper case letter).

(Build_Discriminant_Constraints): Use updated form of
Denotes_Discriminant.
(Process_Subtype): If the subtype is a private subtype whose full view

anomalies in gigi.
(Build_Derived_Record_Type, Collect_Interface_Primitives,
Record_Type_Declaration): The functionality of the subprograms
Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
is now performed by a single routine.
(Build_Derived_Record_Type): If the type definition includes an explicit
indication of limitedness, then the type must be marked as limited here
to ensure that any access discriminants will not be treated as having
a local anonymous access type.
(Check_Abstract_Overriding): Issue a detailed error message when an
abstract subprogram was not overridden due to incorrect mode of its
first parameter.
(Analyze_Private_Extension_Declaration): Add support for the analysis of
synchronized private extension declarations. Verify that the ancestor is
a limited or synchronized interface or in the generic case, the ancestor
is a tagged limited type or synchronized interface and all progenitors
are either limited or synchronized interfaces.
Derived_Type_Declaration): Check for presence of private extension when
dealing with synchronized formal derived types.
Process_Full_View): Enchance the check done on the usage of "limited" by
testing whether the private view is synchronized.
Verify that a synchronized private view is completed by a protected or
task type.
(OK_For_Limited_Init_In_05): New function.
(Analyze_Object_Declaration): Move check for limited types later,
because OK_For_Limited_Init requires its argument to have been resolved.
Add -gnatd.l --Use Ada 95 semantics for limited function returns,
in order to alleviate the upward compatibility introduced by AI-318.
(Constrain_Corresponding_Record): If the constraint is for a component
subtype, mark the itype as frozen, to avoid out-of-scope references to
discriminants in the back-end.
(Collect_Implemented_Interfaces): Protect the recursive algorithm of
this subprogram against wrong sources.
(Get_Discr_Value, Is_Discriminant): Handle properly references to a
discriminant of limited type completed with a protected type, when the
discriminant is used to constrain a private component of the type, and
expansion is disabled.
(Find_Type_Of_Object): Do not treat a return subtype that is an
anonymous subtype as a local_anonymous_type, because its accessibility
level is the return type of the enclosing function.
(Check_Initialization): In -gnatg mode, turn the error "cannot
initialize entities of limited type" into a warning.
(OK_For_Limited_Init): Return true for generated nodes, since it
sometimes violates the legality rules.
(Make_Incomplete_Declaration): If the type for which an incomplete
declaration is created happens to be the currently visible entity,
preserve the homonym chain when removing it from visibility.
(Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
inherited subprograms.
(Access_Definition): If this is an access to function that is the return
type of an access_to_function definition, context is a type declaration
and the scope of the anonymous type is the current one.
(Analyze_Subtype_Declaration): Add the defining identifier of a regular
incomplete subtype to the set of private dependents of the original
incomplete type.
(Constrain_Discriminated_Type): Emit an error message whenever an
incomplete subtype is being constrained.
(Process_Incomplete_Dependents): Transform an incomplete subtype into a

and subtypes.

(Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
of the explicit dereference of the allocator to the result subtype of
the build-in-place function. This is needed to satisfy type checking
in cases where the caller's return object is created by an allocator for
a class-wide access type and the type named in the allocator is a
specific type.
(Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
conversion of the reference to the declared object to the result subtype
of the build-in-place function. This is needed to satisfy type checking
in cases where the declared object has a class-wide type. Also, in the
class-wide case, change the type of the object entity to the specific
result subtype of the function, to avoid passing a class-wide object
without explicit initialization to the back end.
(Register_Interface_DT_Entry): Moved outside the body of

involve init of a separate object (for example, actuals of subprogram
calls).
(Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
handling calls to build-in-place functions as the initialization of an

(Expand_Inlined_Call.Process_Formals): When replacing occurrences of
formal parameters with occurrences of actuals in inlined body, establish
visibility on the proper view of the actual's subtype for the body's
context.
(Freeze_Subprogram): Do nothing if we are compiling under full ABI
compatibility mode and we have an imported CPP subprogram because
for now we assume that imported CPP primitives correspond with
objects whose constructor is in the CPP side (and therefore we
don't need to generate code to register them in the dispatch table).

aligned selected component.

point where the RACW was declared, validate the primitive operations
with respect to E.2.2(14) when it finally is frozen.
(Build_Initialization_Call,Expand_Record_Controller): Rename
Is_Return_By_Reference_Type to be Is_Inherently_Limited_Type, because
return-by-reference has no meaning in Ada 2005.

with controlled types (because the dispatch table of the ancestor is
null and hence these entries cannot be inherited). This is required to
elaborate well the dispatch table.

(Expand_N_Attribute_Reference, case Attribute_Constrained): For Ada_05,

an aliased prefix must be known to be constrained in order to use True

* sem_res.adb (Resolve_Unary_Op): Add warning for use of unary minus
with multiplying operator.
(Expected_Type_Is_Any_Real): New function to determine from the Parent
pointer whether the context expects "any real type".
(Resolve_Arithmetic_Op): Do not give an error on calls to the
universal_fixed "*" and "/" operators when they are used in a context
that expects any real type. Also set the type of the node to
Universal_Real in this case, because downstream processing requires it
(mainly static expression evaluation).
Reword some continuation messages
Add some \\ sequences to continuation messages
(Resolve_Call): Refine infinite recursion case. The test has been
sharpened to eliminate some false positives.
Check for Current_Task usage now includes entry barrier, and is now a
warning, not an error.
(Resolve): If the call is ambiguous, indicate whether an interpretation
is an inherited operation.
(Check_Aggr): When resolving aggregates, skip associations with a box,
which are priori correct, and will be replaced by an actual default
expression in the course of expansion.
(Resolve_Type_Conversion): Add missing support for conversion from
a class-wide interface to a tagged type. Minor code cleanup.
(Valid_Tagged_Converion): Add support for abstact interface type
conversions.
(Resolve_Selected_Component): Call Generate_Reference here rather than
during analysis, and use May_Be_Lvalue to distinguish read/write.
(Valid_Array_Conversion): New procedure, abstracted from
Valid_Conversion, to incorporate accessibility checks for arrays of
anonymous access types.
(Valid_Conversion): For a conversion to a numeric type occurring in an
instance or inlined body, no need to check that the operand type is
numeric, since this has been checked during analysis of the template.
Remove legacy test for scope name Unchecked_Conversion.
