Subject: [PULL 01/18] target/ppc: Improve syscall exception logging
Date: Thu,  7 May 2020 15:02:11 +1000	[thread overview]
Message-ID: <20200507050228.802395-2-david@gibson.dropbear.id.au> (raw)
In-Reply-To: <20200507050228.802395-1-david@gibson.dropbear.id.au>

From: Nicholas Piggin <npiggin@gmail.com>

system calls (at least in Linux) use registers r3-r8 for inputs, so
include those registers in the dump.

This also adds a mode for PAPR hcalls, which have a different calling
convention.
