Hi,
this series was originally posted by Peer Adelt some time ago[1], but still had
some problems which I tried to fix with this patch set.
The tricky bits here were the FTOUZ and MADD/MSUB.F instructions. The latter
had the problem of not giving back the correct NAN when the result of the
add/sub of muladd/sub was invalid. I addressed that by fixing up the value
later, which feels hacky. I feel the better solution would be extending
softfloat to recognize ADD_NAN's and emitting the correct NAN there. On the
other hand it's a change in softfloat for a small edge case. Any comments on
that?
Additionally this patch set adds the UPDFL instructions.
Cheers,
Bastian
