Subject: predict.c (maybe_hot_frequency_p): Use opt_for_fn.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=7525bb7d7fe6d44c4634401e7468c408cee94d81;p=gcc.git

predict.c (maybe_hot_frequency_p): Use opt_for_fn.


	* predict.c (maybe_hot_frequency_p): Use opt_for_fn.
	(optimize_function_for_size_p): Likewise.
	(probably_never_executed): Likewise; replace cfun by fun.
