From 43595db30274f714e2b1f6120c2f5ec4c41614fe Mon Sep 17 00:00:00 2001 From: Bas Nieuwenhuizen Date: Wed, 23 Aug 2017 22:28:06 +0200 Subject: [PATCH] ac/nir: Cast sources of integer ops to int. The int32->float semantic conversion got dropped in a testcase, because the src was already float. On closer inspection I decided to add a few more casts for integer op operands to be safe too.
