Hi,

This patch improves model_order_p to use non-reg-pressure version of rank_for_schedule when it needs to break the tie.  At the moment it is comparing INSN_PRIORITY by itself, and it seems prudent to outsource that to rank_for_schedule.

Bootstrapped on x86_64-linux-gnu and regtested on arm-linux-gnueabihf and aarch64-linux-gnu.

OK to apply?

Thank you,
