--- Comment #1 from Joel Sherrill <joel at gcc dot gnu.org> ---
I ran a git bisect and it didn't narrow it down much but I hope this helps.
After the list of candidates, I am posting the full git bisect log.
Bisecting: 27 revisions left to test after this (roughly 5 steps)
[9d0ddb1d2f78d8f75d1663c450bfb79a434316a4] -fuse-caller-save - Enable for MIPS
running /users/joel/test-gcc/test.sh
There are only 'skip'ped commits left to test.
The first bad commit could be any of:
