Hello,
I'd like to add the attached SH test cases to verify the auto-inc-dec
pass operation on the SH target.
Checked by invoking the individual test cases manually with make
check-gcc on sh-sim. Some of the tests pass, some of them don't because
of the auto-inc-dec issues mentioned in the PR.
Cheers,
Oleg
