From cf66c831c1e05bbea0ef859ed3ae0027c476c618 Mon Sep 17 00:00:00 2001 From: Richard Biener Date: Tue, 26 Mar 2019 14:56:30 +0000 Subject: [PATCH] tree-inline.c (remap_gimple_stmt): Cache gimple_block. 2019-03-26 Richard Biener * tree-inline.c (remap_gimple_stmt): Cache gimple_block. (copy_debug_stmt): Likewise. (expand_call_inline): Likewise. (copy_bb): Avoid redundant lookup & set of gimple_block. * gimple-low.c (lower_gimple_return): Likewise. (lower_builtin_setjmp): Likewise.
