Hi,
Trunk GCC shows massive (2 compile-time and 6 run-time) failures on SPEC
CPU2000 and CPU2006 at i386 and x86_64 on -O2 optimization level.
Regression introduced somewhere between revision 122487 and 122478.
There are three checkins, candidates for the root of regression:
http://gcc.gnu.org/viewcvs?view=rev&revision=122487
http://gcc.gnu.org/viewcvs?view=rev&revision=122484
http://gcc.gnu.org/viewcvs?view=rev&revision=122479
Here is the list of failures:
