- Subject: [PATCH] gas/opcodes: blackfin: punt BYTEOP2M insn support
The BYTEOP2M insn was part of the initial Blackfin designs, but never made
it into any actual silicon. So punt support for it.
Signed-off-by: Mike Frysinger <vapier@gentoo.org>
gas/:
2010-02-04 Mike Frysinger <vapier@gentoo.org>
* config/bfin-lex.l (BYTEOP2M): Remove tokenization.
* config/bfin-parse.y (BYTEOP2M): Delete token.
(asm_1): Remove BYTEOP2M insn matching.
