From 9f64bb2312dece0bba02bcbaf0c48d27d2f69daf Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Mon, 16 Sep 2013 23:41:57 -0700 Subject: [PATCH] i965: Fix brw_gs_prog_data_compare to actually check field members. &a and &b are the address of the local stack variables, not the actual structures. Instead of comparing the fields of a and b, we compared ...some stack memory. Not a candidate for stable since GS code doesn't exist in 9.2.
