From 537d3df97466835ad6438fe2c9121283e0da1bcd Mon Sep 17 00:00:00 2001 From: Francisco Jerez Date: Fri, 26 Feb 2016 17:04:38 -0800 Subject: [PATCH] i965: Pass symbolic swizzle to brw_swizzle() as a single argument. And replace brw_swizzle1() with brw_swizzle(). Seems slightly cleaner and will allow reusing brw_swizzle() in the vec4 back-end more easily.
