[PATCH] ARM: Fix VEXT encoding

[Amaury de la Vieuville]

Hi,

This patch enforces the following rule at the MC layer for the VEXT instruction:

A8.8.316 VEXT
if Q == '0' && imm4<3> == '1' then UNDEFINED;

When not used as a quadword operation, VEXT's imm4 operand must be of the form 0b1xxx.

Thanks,
Amaury
