Subject: Fix ICE building deepsjeng with -fprofile-use
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=cfb04e0de6aa438df9d8b83a3d8c7f93789b5c9f;p=thirdparty%2Fgcc.git

Fix ICE building deepsjeng with -fprofile-use

The problem here is division by zero, since adjusted 0 > precise 0. Fixed by
using right test.

gcc/ChangeLog:

	PR ipa/119924
	* ipa-cp.cc (update_counts_for_self_gen_clones): Use nonzero_p.
	(update_profiling_info): Likewise.
	(update_specialized_profile): Likewise.
