From 8b92052f1092048306cb85abb29599918ac33bd7 Mon Sep 17 00:00:00 2001 From: Rob Clark Date: Wed, 23 Oct 2019 09:50:22 -0700 Subject: freedreno/ir3/ra: move regs_count==0 check Fold it in to writes_gpr() (since a register that does not reference any registers by definition does not write a register). This lets us avoid having to handle this case in a few other places.
