Oops sorry, forgot redhat/gcc-4_4-branch has this function backported.
Fixed now.

It does not look like: the patch in comment #6 does not fix pr44229.

I also did a powerpc64-linux bootstrap and regtest (both 32-bit and 64-bit) and
I didn't see any new failures and I also did not see any extra UNSUPPORTED
tests. The only time UNSUPPORTED showed up in the test_sum

For me it bootstrapped/regtested on 4.4 branch without any testsuite changes
(both 32-bit and 64-bit).
To see the unsupported tests difference, you can

Bootstrap of trunk went fine. Regression test (contrib/test_summary) showed the
following difference between base/patched versions, but didn't have any
testcases show up in the diff, so not sure what to make of th

If you could, it would be very much appreciated. Starting 4.4

No I didn't bootstrap/regtest. I can take care of trunk if you want to do 4.4.

Have you also bootstrapped/regtested the patch? I can do so (easily for 4.4
branch, with more effort for the trunk), but haven't done that yet.

rs6000.c already has rs6000_emit_stack_tie and calls it in several places in
the epilogue generation, I guess we just should add another call to this.

Yes, it is related, but solving it in the scheduler in generic way isn't going
to be trivial.
E.g. x86_64 emits memory_blockage early in ix86_expand_epilogue:
