Hi,
The attached patch is to fix PR target/50068. sh_output_mi_thunk
calls dbr_schedule which doesn't expect to be called in that
situation. Although we could set the environment in output_mi_thunk
in such a way to enable dbr_schedule, it looks a bit overkill for
this relatively rare optimization.
The patch simply removes that use of dbr_schedule. Tested on
sh4-unknown-linux-gnu with no new failures. Applied on trunk.
Regards,
kaz
