From 72cbd2d4e77c782fa67b96ab12e2d2ed60cc7fb7 Mon Sep 17 00:00:00 2001 From: Alyssa Rosenzweig Date: Fri, 30 Aug 2019 10:48:41 -0700 Subject: [PATCH] pan/midgard: Allow NULL argument in mir_has_arg It's sometimes convenient to call this with no instruction specified. By definition, a missing instruction cannot reference any argument, so let's check for NULL and shortciruit to false.
