I think sysdeps/ieee754/dbl-64/e_remainder.c is ok. But I am not sure
about the rest of ieee754. I noticed quite a few ieee754 bugs while
working on ia64. But that was before libm from IBM was imported. Since
ia64 has its own ieee754 math library now, I am afraid the current IBM
ieee754 math library is not well tested as before. Do we have a
configure option to disable the x86 asm version of ieee754 math so that
we can test the IBM ieee754 math library on x86?
