From 203f37540a698a812f0a66e2f3f1fff954af22ab Mon Sep 17 00:00:00 2001 From: Rob Clark Date: Wed, 18 Mar 2015 19:26:13 -0400 Subject: [PATCH] freedreno/ir3: add ir3 builder helpers Add helpers for constructing SSA forms of instructions. Only partial cat5/cat6 coverage.. but we can add stuff as needed.
