[PULL 02/39] target/arm: Fix alignment for VLD4.32 |
Date: |

From: Clément Chigot <chigot@adacore.com>
When requested, the alignment for VLD4.32 is 8 and not 16.
See ARM documentation about VLD4 encoding:
ebytes = 1 << UInt(size);
if size == '10' then
alignment = if a == '0' then 1 else 8;
else
alignment = if a == '0' then 1 else 4*ebytes;
