Subject: [PATCH 8/8] target/ppc: 405: System call exception cleanup
Date: Mon, 10 Jan 2022 15:15:46 -0300 [thread overview]
Message-ID: <20220110181546.4131853-9-farosas@linux.ibm.com> (raw)
In-Reply-To: <20220110181546.4131853-1-farosas@linux.ibm.com>
There's no sc 1.
We also only used env->nip because of the vhyp code, so change to
'vector' now.
