Subject: [PATCH 1/8] target/ppc: Print out literal exception names in logs
Date: Wed, 22 Dec 2021 07:40:18 +0100	[thread overview]
Message-ID: <20211222064025.1541490-2-clg@kaod.org> (raw)
In-Reply-To: <20211222064025.1541490-1-clg@kaod.org>

It facilitates reading the logs when mask CPU_LOG_INT is activated. We
should do the same for error codes.
