Subject: [Qemu-devel] [PATCH 0/2] target-arm: fix Neon VUZP, VZIP instructions
Date: Fri, 11 Feb 2011 16:13:59 +0000 [thread overview]
Message-ID: <1297440841-17979-1-git-send-email-peter.maydell@linaro.org> (raw)
This patch series is a pair of patches from the meego tree which
fix bugs in the Neon VZIP and VUZP instructions by abandoning
the existing inline implementations in favour of calling out to
a straightforward helper function. The inline routines could
generate 50+ TCG ops each, which is well over the recommended
limit in tcg/README for using helpers instead; they also did
not give the correct results...
I've tested these patches using the usual random instruction
generation approach.
