When regrename is enabled, it makes new copies of its replacement registers, which means that pointer equality tests can't be used afterwards to check whether two regs are equal. sched_insn_conditions_mutex_p has one such test, and it causes pessimized code in some situations on C6X.The following patch fixes it. Regression tested with a 4.5 c6x-elf compiler. I tried to bootstrap ia64, but that has PR48496. Ok?
Sure, It is ok. Thanks, Bernd.
