I've confirmed that the problem is caused by '-ftree-vectorize' passed to
compile gcc. More precisely, a 'movdqa' instruction in constraint_operands()

CFLAGS? I added -march=pentium-m -ftree-vectorize -mfpmath=sse,387 and
-fomit-frame-pointer in addition to -O2.

Sorry, forgot to mention that I use -mfpmath=sse,387 in my spec file.
