- Subject: [PATCH] gas: blackfin: add missing register move insns
From: Robin Getz <robin.getz@analog.com>
The Blackfin ISA supports moving just about anything to/from EMUDAT, so
make sure the assembler accepts these insns too.

* config/bfin-defs.h (IS_EMUDAT): New define.
* config/bfin-parse.y: Accept EMUDAT for any register move.
