[Qemu-devel] [PATCH 00/10] Fix Neon shift instructions


From: Peter Maydell
Subject: [Qemu-devel] [PATCH 00/10] Fix Neon shift instructions
Date: Tue, 15 Feb 2011 13:44:40 +0000

This patch series fixes bugs in the Neon shift instructions
VRSHR, VRSRA, VQRSHRN, VQRSHRUN, VRSHRN, VQSHRN, VSHRN, VQSHRUN,
VRSHL, and VQRSHL. It is based on the v3 patchset Christophe
sent recently, with some fixes for minor nits in those patches,
plus some patches from me which fix problems with shifts by
large shift counts and an issue with overlapping source and
destination registers.

With this patchset qemu passes random instruction sequence
testing for all these instruction patterns.

Christophe Lyon (5):
  target-arm: Fix rounding constant addition for Neon shifts
  target-arm: Fix unsigned VRSHL.s8 and .s16 right shifts by type width
  target-arm: fix unsigned 64 bit right shifts.
  target-arm: fix Neon VQSHRN and VSHRN.
  target-arm: fix decoding of Neon 64 bit shifts.

Peter Maydell (5):
  target-arm: Fix signed VRSHL by large shift counts
  target-arm: Fix saturated values for Neon right shifts
  target-arm: Fix signed VQRSHL by large shift counts
  target-arm: Fix unsigned VQRSHL by large shift counts
  target-arm: Fix shift by immediate and narrow where src,dest overlap
