The test gcc.target/i386/pr45352.c has started to fail (see
http://gcc.gnu.org/ml/gcc-regression/2013-01/msg00148.html) between revisions
195208 (OK) and 195212 (ICE
/opt/gcc/work/gcc/testsuite/gcc.target/i386/pr45352.c: In function 'foo':
/opt/gcc/work/gcc/testsuite/gcc.target/i386/pr45352.c:25:1: internal compiler
error: in add_insn_mem_dependence, at sched-deps.c:1717
}
The options -O3 -march=amdfam10 -fselective-scheduling2 are enough to trigger
the ICE.
It is likely due to revision 195211
