[PATCH] opcodes: blackfin: constify formatting related structures

[Mike Frysinger <vapier at gentoo dot org>]

No need for these local structures related to formatting of output to
be writable, so constify the whole shebang.

Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2010-09-21  Mike Frysinger  <vapier@gentoo.org>

	* bfin-dis.c (constant_formats): Constify the whole structure.
	(fmtconst): Add const to return value.
	(reg_names): Mark const.
	(decode_multfunc): Mark s0/s1 as const.
	(decode_macfunc): Mark a/sop as const.
