From 0a155538eb7e7870b99fb8b3fd8e2a268361d2c8 Mon Sep 17 00:00:00 2001 From: Ilia Mirkin Date: Sat, 27 Jun 2015 17:38:57 -0400 Subject: gallium/ttn: mark location specially in nir for color0-writes-all We need to distinguish a shader that has separate writes to each MRT from one which is supposed to write the data from MRT 0 to all the MRTs. In TGSI this is done with a property. NIR doesn't have that, so encode it as a funny location and decode on the other end.
