Subject: st/glsl_to_tgsi: handle doubles in array shrinking code.
X-Git-Tag: upstream/17.1.0~13508
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=14506dcae20d89ae9380c7a4f1843586c59db16d;p=platform%2Fupstream%2Fmesa.git

st/glsl_to_tgsi: handle doubles in array shrinking code.

This code takes into account double inputs in the array
shrinking code. This fixes some issues with doubles
and geom/tess inputs.
