Subject: [PATCH v5 09/15] cpu: Move CPUClass::get_crash_info to SysemuCPUOps
Date: Thu, 22 Apr 2021 12:46:58 +0200	[thread overview]
Message-ID: <20210422104705.2454166-10-f4bug@amsat.org> (raw)
In-Reply-To: <20210422104705.2454166-1-f4bug@amsat.org>

cpu_get_crash_info() is called on GUEST_PANICKED events,
which only occur in system emulation.
