Subject: [PATCH v2 01/17] target/arm: Convert Neon 3-reg-same VQRDMLAH/VQRDMLSH to decodetree
Date: Tue, 12 May 2020 17:38:48 +0100 [thread overview]
Message-ID: <20200512163904.10918-2-peter.maydell@linaro.org> (raw)
In-Reply-To: <20200512163904.10918-1-peter.maydell@linaro.org>
Convert the Neon VQRDMLAH and VQRDMLSH insns in the 3-reg-same group
to decodetree. These don't use do_3same() because they want to
operate on VFP double registers, whose offsets are different from the
neon_reg_offset() calculations do_3same does.
Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
---
v1->v2: use do_3same() rather than custom do_vqrdlmah() function
