I see the same on s390x. The culprit appears to be revision 185564.

Now I do: I've just built a 32-bit C-only compiler on
sparc-sun-solaris2.11 at r185563 (i.e. immediately before the culprit
patch), and both the ICE in gcc.dg/torture/pr51106-2.c and the other
execution failures reported are gone.

If they are related (which I doubt), removing the call to cleanup_cfg
in cfgexpand.c should fix them. That's the only real change in
this patch - previously the cleanup_cfg call was conditional on a
present EH region tree (thus, all of these issues are latent and
just require a slightly different testcase)

Indeed: with your patch applied and the call #if 0'd, the tests still pass.

and with #if 1 they fail? As they are wrong-code regressions on
an architecture I have no access to, can you see what is the issue here?
Thanks.

Right. I've compared assembler output for

So, which exact testcase still fails on which target with what options?
Tried gcc.dg/torture/20090618-1.c with -O1 -m32 with sparc-linux cross and
can't reproduce - foo contains
add %sp, -96, %sp
mov 1, %o0
jmp %o7+8
add %sp, 96, %sp
which is correct.

It seems I did this while updating the "Last reconfirmed" date. As I
understand it,
it's a Firefox feature that arises when the web page is inconsistent
with cached
browser page.

Created attachment 28778

gcc48-pr52650.patch
P1 for an error-recovery bug sounds way too high, those should be P4-ish.
Anyway, sounds much easier to me to just not delete the invalid asm goto at all
and instead just drop the invalid inputs (and template to avoid further
warnings/failures). asm goto doesn't have outputs, and the expander should
ensure all the labels are LABEL_REFs, so that part of check_asm_operands
shouldn't fail.

I just restored the previous setting. No objection to revising
it downward.
