--- Comment #4 from Oleg Endo <olegendo at gcc dot gnu.org> --- (In reply to Oleg Endo from comment #3) > Created attachment 34982 [details] > Add sh_pre_ra RTL pass Right now I can think of two alternatives for this PR: - convert respective insns into insn_and_split and emit a pseudo + move in split1 - catch imm8,r0 insns in sh_legitimate_combined_insn in the same way as it's done by the sh_pre_ra pass above. I think that an SH specific pre-RA RTL pass could be useful in the future, for example to improve R0 utilization, even with LRA. Kaz, do you have any opinions?
