From 03b2e0fcdf92c76411a957c3ea898233fb4ce1be Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Fri, 29 Apr 2011 12:17:02 -0700 Subject: [PATCH] i965: Fix fragcoord_w on gen6 with 16-wide. The payload regs can go all the way up to register 60+, so just give them 8 bits to be addressed by instead of 3-4 (which made source_w_reg of 8 end up 0). There's no reason to aggressively pack these fields, as they are just used as compiler information, where being easier to access is probably more important than shaving a byte or two off of the structure. Fixes piglit fragcoord_w.
