I saw the failures in mipsisa64-elf and mipsisa64-elfoabi:

FAIL: gcc.dg/fixed-point/binary.c execution test
FAIL: gcc.dg/fixed-point/convert.c execution test
FAIL: gcc.dg/fixed-point/func-struct.c execution test

I've included your patch in recent mipsisa64-elf testruns and can
confirm that it fixes the failures without introducing any others.

Thanks. I'll test on x86-64 bootstrap shortly.
