[PATCH 00/10] softfloat: misc cleanups |
Date: |

This is a grab-bag collection of cleanups, at least one of which
have been on the to-do list since day we abandoned compatibility
with upstream softfloat.
The compare changes have near-zero effect for float32/float64, since
that's the way they are implemented now. For float128, it simply
removes unneeded complexity.
For floatx80, this fixes bugs vs pseudo-denormals which were only
fixed in floatx80_compare_internal. We could just remove them, as
these interfaces are not used by x87. But I thought it'd be best
to keep the interface compatibility for now.
