Subject: cgraph.h (cgraph_optimize_for_size_p): Declare.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=e6416b305e7c6d1e6d4b1f92bc5875f3c8f4e729;p=gcc.git

cgraph.h (cgraph_optimize_for_size_p): Declare.

	* cgraph.h (cgraph_optimize_for_size_p): Declare.
	* ipa-cp.c (ipcp_insert_stage): Use cgraph_optimize_for_size_p.
	* predict.c (cgraph_optimize_for_size_p): Break out from ...
	(optimize_function_for_size_p) ... here.
