From 3313cc269bd428ca96a132d86da5fddc0f27386a Mon Sep 17 00:00:00 2001 From: Anuj Phogat Date: Mon, 13 Jan 2014 12:26:55 -0800 Subject: i965: Add an option to ignore sample qualifier This will be useful in my next patch which depends on a functionality of _mesa_get_min_invocations_per_fragment() to ignore the sample qualifier (prog->IsSample) based on a flag passed to it.
