Subject: Fix H.J. Lu's alpha-linux bug with TImode constructors.
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=21002281e55cbe5b1c8fbacc9074629612dd1b4a;p=platform%2Fupstream%2Fgcc.git

Fix H.J. Lu's alpha-linux bug with TImode constructors.

	* expr.c (expand_expr): Remove previous incorrect change.
	If target and slot has no DECL_RTL, then call mark_addressable
	again for the slot after we give it RTL.
