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

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.

This fixes a fallout of a recent change clearing the

rules apply again to these types outside the instance.

This patch modifies the handling of warnings on unused formal parameters

From-SVN: r274642

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.

From-SVN: r274640

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.

PR target/91441 - Turn off -fsanitize=kernel-address if TARGET_ASAN_SHADOW_OFFSET is not implemented.

 - -fsanitize=kernel-address will call targetm.asan_shadow_offset ()
   at asan_shadow_offset, so it will crash if TARGET_ASAN_SHADOW_OFFSET
   is not implemented, that's mean -fsanitize=kernel-address is not
   supported for target without TARGET_ASAN_SHADOW_OFFSET implementation.

gcc/ChangeLog:

	PR target/91441
	* toplev.c (process_options): Check TARGET_ASAN_SHADOW_OFFSET is
	implemented for -fsanitize=kernel-address, and merge check logic
	with -fsanitize=address.

testsuite/ChangeLog:

	PR target/91441
	* gcc.target/riscv/pr91441.c: New.

There is no reasonable chance that the SDKs in question will be re-
issued, so the only viable solution is a fixincludes.

This test needs the cpu and machine asserts to be implemented
which hadn't been done for PPC Darwin.  Fixed thus.
