Hello,
This removes the fmac related combine helper construct that was used
before fma.
Tested with
make -k check RUNTESTFLAGS="--target_board=sh-sim
\{-m2/-ml,-m2/-mb,-m2a/-mb,-m2a-single/-mb,-m4/-ml,-m4/-mb,-m4-single/-ml,
-m4-single/-mb,-m4a-single/-ml,-m4a-single/-mb}"
and no new failures.
CSiBE (-O2 -m4-single-ml -mpretend-cmove) shows no changes in
result-size.
OK?
Cheers,
Oleg
ChangeLog:
* config/sh/sh.md (mulsf3_ie): Delete.
(mulsf3_i4): Rename to mulsf3_i.
(mulsf3): Emit mulsf3_i insn.
