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.
