Subject: [Qemu-devel] [PATCH 3/7] tcg/mips: Add use_mips32r6_instructions definition
Date: Wed, 30 Sep 2015 16:30:23 +0100 [thread overview]
Message-ID: <1443627027-2193-4-git-send-email-james.hogan@imgtec.com> (raw)
In-Reply-To: <1443627027-2193-1-git-send-email-james.hogan@imgtec.com>
Add definition use_mips32r6_instructions to the MIPS TCG backend which
is constant 1 when built for MIPS release 6. This will be used to decide
between pre-R6 and R6 instruction encodings.
