--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Is this a regression though?
I see the
FAIL: gcc.dg/pr44194-1.c scan-rtl-dump dse1 "global deletions = (2|3)"
even with gcc 4.7.x, 4.8.x, 4.9.x on ppc64.
There was an attempt to avoid running this test on ppc64-linux:
https://gcc.gnu.org/ml/gcc-patches/2014-08/msg00299.html
r213657 and r213677
but clearly that is not working well.
Don't have a ppc64 box readily available now, so can't quickly analyze what's
going on though. I see:

PASS: gcc.dg/pr44194-1.c scan-rtl-dump-not final "insn[: ][^\n]*set

in the gcc.log from our rpm build, so I'd expect that powerpc_elfv2 is 0 and
therefore the pr44194-1.c test should be skipped as unsupported.
