Subject: [PATCH 1/6] target/ppc: use locally stored msr and avoid indirect access
Date: Mon, 20 May 2024 16:03:24 +0530 [thread overview]
Message-ID: <20240520103329.381158-2-harshpb@linux.ibm.com> (raw)
In-Reply-To: <20240520103329.381158-1-harshpb@linux.ibm.com>
hreg_compute_hflags_value already stores msr locally to be used in most
of the logic in the routine however some instances are still using
env->msr which is unnecessary. Use locally stored value as available.
