From: Peter Crosthwaite <crosthwaitepe...@gmail.com>
Move the target_disas() cris specifics to the QOM disas_set_info() hook
and delete the cris specific code in disas.c.
This also now adds support for monitor_disas() to cris.
E.g.
(qemu) xp 0x40004000
0000000040004000: 0x1e6f25f0
And before this patch:
(qemu) xp/i 0x40004000
0x40004000: Asm output not supported on this arch
After:
(qemu) xp/i 0x40004000
0x40004000: di
(qemu) xp/i 0x40004002
0x40004002: move.d 0xb003c004,$r1
Note: second example is 6-byte misaligned instruction!
