Subject: [PULL 08/26] target/mips: Also display exception names in user-mode
Date: Sun, 13 Dec 2020 21:19:28 +0100 [thread overview]
Message-ID: <20201213201946.236123-9-f4bug@amsat.org> (raw)
In-Reply-To: <20201213201946.236123-1-f4bug@amsat.org>
Currently MIPS exceptions are displayed as string in system-mode
emulation, but as number in user-mode.
Unify by extracting the current system-mode code as excp_name()
and use that in user-mode.
