From 4e990b67cef9a90f362e5a3791234ef779f47bea Mon Sep 17 00:00:00 2001 From: Francisco Jerez Date: Thu, 21 Jul 2016 21:58:56 -0700 Subject: i965: Fix undefined signed overflow in INTEL_MASK for bitfields of 31 bits. Most likely we had only ever used this macro on bitfields of less than 31 bits -- That's going to change shortly.
