From: Mike Frysinger Date: Wed, 22 Sep 2010 21:26:13 +0000 (+0000) Subject: gas: blackfin: fix DBG/DBGCMPLX insn encoding X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=a01eda858f5dc30309e79650b4cc9775416665af;p=binutils-gdb.git gas: blackfin: fix DBG/DBGCMPLX insn encoding Some extended registers when given to the DBG/DBGCMPLX pseudo insns are not encoded properly. So fix them, fix the display of them when being disassembled, and add testcases.
