Subject: [Qemu-devel] [PATCH 2/7] disas/mips: Add R6 jr/jr.hb to disassembler
Date: Wed, 30 Sep 2015 16:30:22 +0100 [thread overview]
Message-ID: <1443627027-2193-3-git-send-email-james.hogan@imgtec.com> (raw)
In-Reply-To: <1443627027-2193-1-git-send-email-james.hogan@imgtec.com>
MIPS r6 encodes jr as jalr zero, and jr.hb as jalr.hb zero, so add these
encodings to the MIPS disassembly table.
