--- Comment #5 from Oleg Endo <olegendo at gcc dot gnu.org> ---
I have tried this on current trunk (GCC 10) and it shows the same issue.
During SH specific sign/zero extension optimizations, the function
sh_extending_set_of_reg::use_as_extended_reg drops the REG_INC note from the
memory insn, when it converts the non-extending memory load (with post-inc
address) into sign-extending memory load.
