Subject: loop-iv: make find_simple_exit static
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b888a051deb7df7587acbe8865513b86d2a1d49f;p=gcc.git

loop-iv: make find_simple_exit static

Function 'find_simple_exit' is used only from loop-iv.c
In 2004-2006 it was also used in predict.c, but since r118694
(992c31e62304ed5d34247dbdef2db276d08fac05) it does not.

gcc/ChangeLog:
	* loop-iv.c (find_simple_exit): Make it static.
	* cfgloop.h: Remove the corresponding prototype.
