From 713c123bfa90fa845cf603a2d82a338b363cb4ee Mon Sep 17 00:00:00 2001 From: Matt Turner Date: Tue, 21 Jan 2020 10:44:59 -0800 Subject: [PATCH] intel/compiler: Don't disassemble align1 3-src operands on Gen < 10 Since the platforms don't support align1 3-src instructions, the contents of these operands are not going to be meaningful. Just don't print them to avoid hitting some assertions in brw_inst functions.
