Hello,
The attached patch improves code generated for byte swap expressions
such as ((x & 0xFF) << 8) | ((x >> 8) & 0xFF).
It seems that currently the tree optimizers only detect bswap32 and
bswap64 but not bswap16 patterns. The patch adds detection for bswap16
patterns by playing along with the

Hello,
The attached patch adds support for the bswap32 built-in on SH.
Tested with
make -k -j8 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.
Cheers,
