Subject: Use variadic template functions for the gimple_build forwarders
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=684c97dd084b7a535deb400ab8b26b914d011c5c;p=platform%2Fupstream%2Fgcc.git

Use variadic template functions for the gimple_build forwarders

The following consolidates the forwarders to gimple_build with
UNKNOWN_LOCATION by using two variadic template functions.  This
makes the code visually less disturbing and is in preparation
of adding more forwarders with different stmt insertion schemes.

2022-05-11  Richard Biener  <rguenther@suse.de>

	* gimple-fold.h (gimple_build): Use variadic template
	functions for the gimple_build API forwarders without
	location_t argument.
