From: Nicolai Hähnle Date: Tue, 2 May 2017 14:21:30 +0000 (+0200) Subject: radeonsi: split per-patch from per-vertex indices X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=cb2ac69628a89a601ff682fdc3bc3c8ee5e306b3;p=mesa.git radeonsi: split per-patch from per-vertex indices Make it a bit clearer that the index spaces are logically seperate by having them defined in different functions.
