Subject: ipa/94947 - avoid using externally_visible_p ()
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b9250b3cb91b667cd67943e0fac94bf39ac089a8;p=gcc.git

ipa/94947 - avoid using externally_visible_p ()

externally_visible_p wasn't the correct predicate to use (even if it
worked), instead we should use DECL_EXTERNAL || TREE_PUBLIC.

2020-05-07  Richard Biener  <rguenther@suse.de>

	PR ipa/94947
	* tree-ssa-structalias.c (refered_from_nonlocal_fn): Use
	DECL_EXTERNAL || TREE_PUBLIC instead of externally_visible.
	(refered_from_nonlocal_var): Likewise.
	(ipa_pta_execute): Likewise.
