From: Marek Olšák Date: Fri, 1 Jul 2016 14:22:05 +0000 (+0200) Subject: radeonsi: clean up shader value metadata code X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=bccf9de4df93a53cad7a3a6ffdcea1ebc956487d;p=mesa.git radeonsi: clean up shader value metadata code No change in behavior. BTW, tbaa_md_kind == 1, which was the magic number in the code.
