Subject: glsl: Do not call lhs->variable_referenced() multiple times
X-Git-Tag: upstream/10.3~2085
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a143fbb3220e4c40cd2c75eca6f3e94fba0fe324;p=platform%2Fupstream%2Fmesa.git

glsl: Do not call lhs->variable_referenced() multiple times

Instead take the result from the first call and use it where needed.
