[Bug rtl-optimization/31944] [4.1/4.2/4.3 Regression] Endless loop while building a 64-bit 2.6.20 kernel
------- Comment #26 from steven at gcc dot gnu dot org 2008-01-10 23:58 -------
Mark, wrt. the release, I recommend this PR shouldn't be a blocker. The
problem is old and is currently latent on the trunk, where it is only exposed
with non-default options (-fno-inline-small-functions).
Obviously, the problem is that the hash of reg 66 is changed after a hash table
element is created for it in the bucket for the original hash. I have no idea
yet whether this is expected, or if not, what is going wrong.
Messing with CSE at this stage may be more dangerous than accepting the status
quo.
