From bcc7eb115ed6e74b87566bbc3a51c444814f1ebe Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Mon, 1 Dec 2014 13:44:04 -0800 Subject: i965: Add var->location != -1 assertions. We shouldn't receive variables with invalid locations set - adding these assertions should help catch problems before they cause crashes later. Inspired by similar code in st_glsl_to_tgsi.
