Subject: [PATCH] Run feedback directed ipa-split for flag_auto_profile
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0f2f068d19a2eed08aaf731fb9070606f0dd2f82;p=thirdparty%2Fgcc.git

[PATCH] Run feedback directed ipa-split for flag_auto_profile

IPA split is now running before auto-profile annotation. Changing it
after annotation as it is done for PGO.

gcc/ChangeLog:

2025-07-21  Kugan Vivekanandarajah  <kvivekananda@nvidia.com>

	* ipa-split.cc (pass_split_functions::gate): Do not run when
	flag_auto_profile.
	(pass_feedback_split_functions::gate): Run when flag_auto_profile.
