From f3e06fcc6add67ed3eeecbce600994ef3220ec1c Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Mon, 19 Jan 2015 23:11:54 -0800 Subject: [PATCH] i965/nir: Print NIR on INTEL_DEBUG=fs. This is useful for debugging and looking for optimization opportunities. It will need to be expanded when we add support for other scalar stages.
