Browse Source 
2020-01-07  Martin Liska  <mliska@suse.cz>

	PR tree-optimization/92860
	* common.opt: Make in Optimization option
	as it is affected by -O0, which is an Optimization
	option.
	* tree-inline.c (tree_inlinable_function_p):
	Use opt_for_fn for warn_inline.
	(expand_call_inline): Likewise.
