Hi,
The gcc.target/sh/pr54089-1.c test case started to fail for SH2A. Due
to different combine paths the expected rotcr insn is sometimes not
generated as expected at -O1. Changing it to -O2 produces the expected
insn sequences. Tested with
make -k check-gcc RUNTESTFLAGS="sh.exp=pr54089-1.c --target_board=sh-sim
\{-m2/-ml,-m2/-mb,-m2a/-mb,-m4/-ml,-m4/-mb,-m4a/-ml,-m4a/-mb}"
Committed as r218795.
Cheers,
Oleg
