From 3dc39d0bca0f06454cb5cddf7571facb7671767a Mon Sep 17 00:00:00 2001 From: Roy Spliet Date: Fri, 6 Feb 2015 22:46:55 +0100 Subject: [PATCH] nv50/ir: Add emit support for MAD IMM format But don't enable generation of it in the opProperties, because we can't guarantee the SDST==SRC2 constraint until after register assignment. We'll add a post-RA folding pass to utilise this.
