14 spec2006 tests also fail after the commit 187459,
(compiled with -O2 -march=corei7 -mtune=corei7 -mavx -m64)
However without -mavx they pass.

I didn't say it did and I didn't merge the PRs. In particular, a PA
issue
was merged with a x86_64 issue. For PA, the patch avoids the
problematic
code in the middle-end and improves call optimization.
There is a generic fix posted for PR53381 that might resolve the x86_64
ICE reported here. I assume the ICE occurs because the x86_64 call
pattern
contains an UNSPEC. See also comment 7 in PR53381.

gcc build for me with -march=native equivalent to -march=bdver1 (and therefore
-mavx)
