Subject: [AUTOFDO] Enable ipa-split for auto-profile
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=53fb5a1a98a2d72ada7786f28e94a724916a39b1;p=thirdparty%2Fgcc.git

[AUTOFDO] Enable ipa-split for auto-profile

ipa-split is not now run for auto-profile. IMO this was an oversight.
This patch enables it similar to PGO runs.

gcc/ChangeLog:

	* ipa-split.cc (pass_feedback_split_functions::clone): New.
	* passes.def: Enable pass_feedback_split_functions for
	pass_ipa_auto_profile.
