Subject: gas: blackfin: clarify some errors with register usage in insns
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=a2c28b80f1bc424f2b8858118634ea8428ffe985;p=binutils-gdb.git

gas: blackfin: clarify some errors with register usage in insns

why exactly we're barfing on these unsupported insns.
