- Subject: [PATCH] gas: blackfin: support ABORT debug insn
There is a pseudo debug insn named ABORT that is commonly used in
simulation, so support it in the assembler too. The disassembler
already supports it.

* bfin-lex.l (abort): Accept case-insensitive abort insn.
* bfin-parse.y (ABORT): Handle the ABORT token.
