What does md5sum have to do with floating point?
The speedup on md5sum probably comes from doubling the number of integer registers, and thereby reducing register spills to the stack.
At any rate, doubling the integer register file should have a minimal impact on floating point codes, since all floating point computation occurs in the floating point register file. One area floating point code will see speedups is in block copies. Non-computational manipulation of floating point data in the integer register file (stuff like memcpy(), structure assignment, array initialization) will speed up.
