Hi,
The attached patch adds some more test cases for PR 50751.
Tested on sh-sim with
make check-gcc RUNTESTFLAGS=sh.exp=pr50751* --target_board=sh-sim
\{-m2/-ml,-m2/-mb,-m2a-single/-mb,-m4-single/-ml,
-m4-single/-mb,-m4a-single/-ml,-m4a-single/-mb}
to confirm that the tests pass as expected.
OK?
Cheers,
Oleg
