Subject: ipa-profile.c (ipa_propagate_frequency_1): Use count instead of frequency.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=7349698ee4147cf36862081e21736d4c2b96b9d9;p=gcc.git

ipa-profile.c (ipa_propagate_frequency_1): Use count instead of frequency.

	* ipa-profile.c (ipa_propagate_frequency_1): Use count instead of
	frequency.
	* cgraph.c (cgraph_edge::dump_edge_flags): Dump sreal frequencies.
	(cgraph_edge::maybe_hot_p): Use sreal frequencies.
