Subject: ipa/94245 - avoid folding when we want an ADDR_EXPR
X-Git-Tag: upstream/12.2.0~17703
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=7a2090b04e54ffccc64ad2dfd5b46eb4bb8ce482;p=platform%2Fupstream%2Fgcc.git

ipa/94245 - avoid folding when we want an ADDR_EXPR

Another case where build_fold_addr_expr is harmful.

2020-03-23  Richard Biener  <rguenther@suse.de>

	PR ipa/94245
	* ipa-prop.c (ipa_read_jump_function): Build the ADDR_EXRP
	directly rather than also folding it via build_fold_addr_expr.
