From: Eric Anholt Date: Wed, 12 Jun 2013 23:57:11 +0000 (-0700) Subject: mesa: Use shared code for converting shader targets to short strings. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=faf3dbad0d30ed36ae6010a90ca2513edb591148;p=mesa.git mesa: Use shared code for converting shader targets to short strings. We were duplicating this code all over the place, and they all would need updating for the next set of shader targets.
