Thanks for working on this. Unfortunately it seems the
http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=195211
change (commit message didn't make it into this PR because of an extra pr after
/ ) regressed i386/pr45352.c testcase on i?86.
./cc1 -m32 -O3 -march=amdfam10 -fselective-scheduling2 -fsel-sched-pipelining
-funroll-all-loops gcc.target/i386/pr45352.c
ICEs now with:
internal compiler error: in add_insn_mem_dependence, at sched-deps.c:1717
