If the -gnatwf switch is used to activate warnings on unreferenced
formal parameters, the warning is no longer given if the subprogram is
dispatching, because such warnings tend to be noise. It is quite common
to have a parameter that is necessary just because the subprogram is
overriding, or just because we need a controlling parameter for the
dispatch.

This patch corrects the code generated by the -gnateV switch in the case
of a private type whose full type is a modular type, removing spurious
run-time failures.
In addition, this corrects the initialization of exception occurrences
in exception handlers to avoid leaving data uninitialized, which caused
-gnateV to raise spurious errors.

* exp_attr.adb (Attribute_Valid): Correct the handling of

fail. The 'Valid attribute is illegal for such types, but we
generate such illegal attribute_references for 'Valid_Scalars,
and we generate 'Valid_Scalars when the -gnateV switch is used.

confusing.

This change lifts the restriction that was still present in the new
on-demand instantiation scheme for the body of generics instantiated in
non-main units.
The instantiations that are compilation units were still dealt with in
the old-fashioned way, that is to say the decision of instantiating the
body was still made up front during the analysis of the instance
declaration, instead of being deferred until after a call to an inlined
subprogram is encountered.
This should save a few more cycles when full inlining across units is
enabled, but there should otherwise be no functional changes.

For tagged types not defined at library level that derive from library
level tagged types the compiler may generate code to initialize their
dispatch table of predefined primitives copying from the parent type
data stored in memory after the dispatch table of the parent; that is,
at runtime the initialization of dispatch tables overflows reading the
parent dispatch table.
This problem does not affect the execution of the program since the
target dispatch table always has enough space to store the extra data,
and after such copy the compiler generates code to complete the
initialization of the dispatch table.
The following test must compile and execute without errors.
package pkg_a is
type Root is tagged null record;
end pkg_a;
with pkg_a;
procedure main is
type Derived is new pkg_a.Root with null record; -- Test

The recent introduction of GNAT.Sockets IPv6 support broke support for

This fixes a fallout of a recent change clearing the
Is_Generic_Actual_Type on the implicit full view of a private actual
type in an instance. This flag is used to help disambiguating formal
types instantiated on the same actual type within an instance, but it
should be cleared outside the instance to let the usual disambiguation
rules apply again to these types outside the instance.
This in particular means that Exp_Dist cannot rely on it to detect
subtypes representing generic actual types, hence the need for the new
predicate.

This patch modifies the handling of warnings on unused formal parameters
of generic subprograms. Previously such warnings were placed on the
formal appearing in the subprogram declaration, in contrast with
warnings on non-generic subprograms, where the warning is placed on the
corresponding entity in the body of the subprogram. This patch makes the
handling of both cases uniform. It is preferable to place the warning in
the body because this also provides a better suggestion for the
placement of an Unreferenced pragma to suppress the warning when desired.

This patch fixes an old-standing problem with premature freezing. When a
derived type declaration includes a constraint, we generate a subtype
declaration of an anonymous base type, with the constraint given in the
original type declaration, Conceptually, the bounds are converted to the
new base type, and this conversion freezes (prematurely) that base type,
when the bounds are simply literals. As a result, a representation
clause for the derived type is then rejected or ignared. This procedure
recognizes the simple case of literal bounds in derived enumeration type
declarations, which allows us to indicate that the conversions are not
freeze points, and the subsequent representation clause can be accepted.

This gets rid of a small issue in the inlining machinery: under very
peculiar circumstances, it would add a pending instantiation for the
body of a generic package at the point of call to an inlined subprogram
of the instance. That's theoritically problematic because the saved
context is that of the call and not that of the instance in this case,
although the strict conditions ensure that this doesn't make a real
difference in practice.
Now that the machinery can perform the pending instantiations on demand,
we can optimistically add more of them when the instantiations are
analyzed and thus remove the problematic handling at the point of call.
No functional changes.

failed.

In gccgo, we insert the write barriers in the frontend, and so we
cannot completely prevent write barriers on stack writes. So it
is possible for a bad pointer appearing in the write barrier
buffer. When flushing the write barrier, treat it the same as
sacnning the stack. In particular, don't mark a pointer if it
does not point to an allocated object. We already have similar
logic in greyobject. With this, hopefully, we can prevent an
unallocated object from being marked completely.
