PR target/91441 - Turn off -fsanitize=kernel-address if… · 6490e255

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.

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

    When a defer is executed at most once in a function body,

runtime: scan write barrier buffer conservatively · 777c0282

    
    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.

[gensupport] PR 91255: Do not error out immediately on set_attr_alternative with define_subst · 12f78d8b

I'm trying to add a define_subst use in the arm backend but am getting many build errors complaining about:
`set_attr_alternative' is unsupported by `define_subst'

Looking at the gensupport.c code it iterates over all define_insns and errors if any of them have set_attr_alternative.

The usecase I'm targetting doesn't involve patterns with set_attr_alternative, so I would like to make the define_subst handling
more robust to only error out if the define_subst is actually attempted on a set_attr_alternative.

This patch produces the error only if the set_attr_alternative attr matches the subst name.
This allows a build of the arm backend with a define_subst usage to succeed.
