This patchset fixes bugs in the decode and implementation
of the ARM Neon VQSHL (register) instruction form. It is
a split out version of those parts of the maemo-qemu tree
commit 03a2445a which deal with this instruction form;
the remainder which address VQSHL (immediate) I'll send
in a separate patchset.

The 'Fix VQSHL of signed 64 bit values by shift counts >= 64'
patch is a bug fix which does not appear in the maemo-qemu
patch. 'Correct result in saturating cases for VQSHL of s8/16/32'
does appear, but I refactored it a little to be clearer;
these two therefore have me as the author.

These patches have been tested by running random instruction
sequences and comparing against A8 hardware.


Juha Riihimäki (3):
  ARM: Fix arguments passed to VQSHL helpers
  ARM: Fix VQSHL of signed 64 bit values
  ARM: remove pointless else clause in VQSHL of u64

Peter Maydell (2):
  ARM: Fix VQSHL of signed 64 bit values by shift counts >= 64
  ARM: Correct result in saturating cases for VQSHL of s8/16/32
