From 73a63ccf2f0f856eebf7fee67309fe2a276c39d6 Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Wed, 22 Sep 2010 20:59:00 +0000 Subject: opcodes/gas: blackfin: support OUTC debug insn The disassembler has partial (but incomplete/broken) support already for the pseudo debug insn OUTC, so let's fix it up and finish it. And now that the disassembler can handle it, make sure our assembler can output it too.
