Well, the instantiate virtual regs pass just deletes the asm as having
impossible constraints and does not clean up cfg after itself. As the asm is
actually a jump in this case, everything blows up.
The trivial patch below makes this work for -O[012]. Any other places in
function.c need patching up? Jakub, what do you think?

Shorter testcase for gcc.c-torture/compile/ :
int
foo (int x)
{
asm goto ("" : : "i" (x) : : lab);
return 1;
lab:
return 0;
}
Yeah, I think delete_insn_and_edges is the right fix here. You might also add
into the testsuite:
int
bar (int x)
{
asm goto ("" : : "i" (x) : : lab);
__builtin_unreachable ();
lab:
return 0;
}
(fortunately at this point the bb ending with the asm goto still has a fallthru
successor, otherwise purge_dead_edges wouldn't work).

It's failing not only on sh, but on x86-64 too, started with (no surprise here)
r185564:
2012-03-20 Richard Guenther <rguenther@suse.de>
* tree-pass.h (pass_rtl_eh): Remove.
Richard, the issue here was that when removing the wrong asm jump, we need also
to fixup the cfg. This can be done by the purge_dead_edges call because as
Jakub mentioned in comment #3 the basic block with the asm has two successor
edges, one of them is fallthru. After your patch (probably because of the new
call to cleanup_cfg) there is no more fallthru edge but a single edge. Which
blows up purge_dead_edges called from delete_insn_and_edges. So probably
purge_dead_edges should be fixed to expect not having a fallthru edge -- Jakub
may have more context here.

Yes, I would say it is the same. It's strange that Richard didn't see this in
his testing.

So, something like the below patch, or even better -- as we want to fold all
RTL-build related pseudo passes into expand, make pass_instantiate_virtual_regs
also the expand part (thus, until the into_cfglayout pass), and then the new
cleanup_cfg will nicely work at the end of expand.

Looks reasonable. Though I think that whoever removed the fallthru
edge should have adjusted the flags on the others.

That's simply delete_basic_block at cfgcleanup.c:2612 -- we have block 2 with
two successors 4 and 5, and block 4 is trivially dead (empty, no succ, etc.),
so when removing block 4 we just remove the 2->4 edge which is the only
fallthru one. Which seems fine as the asm in question is seen by the rest of
code as an unconditional jump then. Only when we remove it, we get no jump and
still no fallthru bit, which confuses purge_dead_edges.

Not quite, the last message was
