Subject: [Qemu-devel] [PATCH v3 3/3] target/ppc: Enable reporting of SPRs to GDB
Date: Tue, 15 Jan 2019 17:37:50 -0200	[thread overview]
Message-ID: <20190115193750.17234-4-farosas@linux.ibm.com> (raw)
In-Reply-To: <20190115193750.17234-1-farosas@linux.ibm.com>

This allows reading and writing of SPRs via GDB:

(gdb) p/x $srr1
$1 = 0x8000000002803033

(gdb) p/x $pvr
$2 = 0x4b0201
(gdb) set $pvr=0x4b0000
(gdb) p/x $pvr
$3 = 0x4b0000

They can also be shown as a group:
(gdb) info reg spr
