From 8a7cee2fcf1520efea6103ab67e34b5fdc4a44fa Mon Sep 17 00:00:00 2001 From: Liu Jing Date: Mon, 14 Oct 2024 16:01:16 +0800 Subject: [PATCH] target/ppc: Zero second doubleword for VSX madd instructions MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit In 205eb5a89e we updated most VSX instructions to zero the second doubleword, as is requested by PowerISA since v3.1. However, VSX_MADD helper was left behind unchanged, while it is also affected and should be fixed as well. This patch applies the fix for MADD instructions.
