Subject: [Qemu-devel] [PULL 05/10] disas/mips: Add R6 jr/jr.hb to disassembler
Date: Wed, 21 Oct 2015 11:42:54 -1000 [thread overview]
Message-ID: <1445463779-5823-6-git-send-email-rth@twiddle.net> (raw)
In-Reply-To: <1445463779-5823-1-git-send-email-rth@twiddle.net>
From: James Hogan <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.
