From ea7b4d25c8da352f4ca0dcaefa4fadb9e202636e Mon Sep 17 00:00:00 2001 From: Francisco Jerez Date: Fri, 6 Feb 2015 15:06:05 +0200 Subject: [PATCH] i965/fs: Fix lower_load_payload() to take into account non-zero reg_offset. Fixes metadata guess when instructions in the program specify a destination register with non-zero reg_offset and when the payload of a LOAD_PAYLOAD spans several registers.
