Subject: [Bug target/34087] New: ICE in regrename.c for movdf_hardfloat64_mfpgpr
Date: Tue, 13 Nov 2007 21:07:00 -0000 [thread overview]
Message-ID: <bug-34087-14936@http.gcc.gnu.org/bugzilla/> (raw)
The following attatchment from the cpu20006 benchmark leslie3d ICEs in the
following manner. The problem appears to be a latent bug that has come and gone
a couple times (I saw it earlier on the gamess benchmark too). Recent
mainlines compile it fine, but revision 128829 exhibits the problem. Opening a
bugzilla since I haven't been able to spend as much time digging into it as I'd
thought/hoped, and don't want to lose track of it.
