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.
