- Subject: [patch] m68k: Rename %mbb to %mbo.
Hi,
Attached is a patch to rename %mbb to %mbo, which is a CPU register in
fido, a m68k variant.
Various documents consistently use MBO for the Memory Base Offset
register. I don't remember why I picked MBB in the first place.
For backward compatibility, gas still accepts %mbb, but the
disassembly comes out as %mbo.
Tested by running the gas testsuite. OK to apply?

* config/m68k-parse.h (m68k_register): Use MBO instead of MBB.
(last_movec_reg): Change to MBO.
* config/tc-m68k.c (fido_ctrl): Use MBO instead of MBB.
(m68k_ip): Use MBO instead of MBO.
(init_table): Use MBO instead of MBO. Add an entry for mbo.
