From b05eab9dc56ac179dd59c3c5cba7931c9ec4ff23 Mon Sep 17 00:00:00 2001 From: Richard Sandiford Date: Thu, 29 Oct 2015 15:23:51 +0000 Subject: [PATCH] Remove redundant variable from tree-call-cdce.c shrink_wrap_one_built_in_call had both guard_bb and guard_bb0. It looks like an earlier version of the pass may have updated one of the variables in the while loop, but now they're just two names for the same thing. Tested on x86_64-linux-gnu, aarch64-linux-gnu and arm-linux-gnueabi. gcc/ * tree-call-cdce.c (shrink_wrap_one_built_in_call): Remove guard_bb0 and use guard_bb throughout.
