Remove global call sets: cfgcleanup.c
old_insns_match_p just tests whether two instructions are similar enough to merge. With insn_callee_abi it makes more sense to compare the ABIs directly. 2019-09-30 Richard Sandiford <richard.sandiford@arm.com> gcc/ * cfgcleanup.c (old_insns_match_p): Compare the ABIs of calls instead of the call-clobbered sets.
