[Qemu-devel] [PATCH 0/5] ARM: fix VQSHL (register)
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.
