From: Víctor Colombo Date: Tue, 6 Sep 2022 12:55:20 +0000 (-0300) Subject: target/ppc: Zero second doubleword for VSX madd instructions X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=9f097daa5483cdb7d745740606232c931d32b796;p=qemu.git target/ppc: Zero second doubleword for VSX madd instructions 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.
