I used "-O3 -funroll-loops -msse2 -mfpmath=sse -ffast-math" to
compile it.

I've started to work on this. Probably it will take day or two to fix it is
hard to find a wrong code in a big program as apsi.

--- Comment #6 from Vladimir Makarov <vmakarov at redhat dot com> 2011-03-31 01:05:33 UTC ---
The problem was in a typo in ira-costs.c which in some cases results in
assigning INT_MAX to memory_cost and as consequence ALL_REGS to some allocnos.
After some optimizations the allocno which got a hard reg and corresponds to
loop which contains subloops and never referenced in its loop is spilled in
function move_spill_restore and because it is never referenced in the loop, it
got zero costs for all hard regs.
In reload, the allocno is assigned to a mmx hard register through IRA which
corrupted by sse registers usage in other program places.
I'll sent a patch soon to fix this.
