From ff18ad15259c8978f85344934b146ff7b9ee07e1 Mon Sep 17 00:00:00 2001 From: Richard Sandiford Date: Tue, 10 Sep 2019 18:56:43 +0000 Subject: [PATCH] Make more use of regs_invalidated_by_call This cleans up a couple of places in which the previous patch had: call_used_or_fixed_regs & ~fixed_reg_set In that context, regs_invalidated_by_call is IMO more obvious. 2019-09-10 Richard Sandiford gcc/ * config/frv/frv.c (frv_ifcvt_modify_tests): Use regs_invalidated_by_call & ~fixed_reg_set instead of call_used_or_fixed_regs & ~fixed_reg_set. * config/sh/sh.c (output_stack_adjust): Likewise.
