I'm not certain if this is AIX-specific or more fallout from wchar
size. I could ignore with target powerpc-ibm-aix* or with target !
Any further insight / preference?
I didn't try to address that specific failure yet -- my patch just fixed
two earlier warnings.
That specific failure either requires a deeper testsuite fix for
possibly even a fix to the compiler -- I haven't really analyzed it yet
(it's a failure to optimize issue and I've generally avoided looking at
You could xfail it on 4byte_wchar_t.
I fixed similar failures in gcc.c-torture/execute/memchr-1.c some
time ago by adjusting the test (r265020) so I suspect something
along those lines would work here as well if we would rather avoid
