From 4d979c9ffbe19931bd8b44810eb3c1c396798911 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?V=C3=ADctor=20Colombo?= Date: Wed, 4 May 2022 18:05:33 -0300 Subject: target/ppc: Remove msr_ir macro MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit msr_ir macro hides the usage of env->msr, which is a bad behavior Substitute it with FIELD_EX64 calls that explicitly use env->msr as a parameter.
