[Qemu-devel] [PATCH] target-arm: raise exception on misaligned LDREX operands

Qemu does not generally perform alignment checks. However, the ARM ARM requires implementation of alignment exceptions for a number of cases including LDREX, and Windows-on-ARM relies on this. This change adds a helper function to raise an alignment exception (data abort), a framework for
