[PATCH 00/10] softfloat: misc cleanups


From: Richard Henderson
Subject: [PATCH 00/10] softfloat: misc cleanups
Date: Fri, 15 May 2020 12:01:43 -0700

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.
