For example the Xscale datasheet defines:
" Both LDRD and STRD instructions will generate an alignment exception
when the address bits [2:0] = 0b100."

LDRD and STRD are load/store double instructions, and they are used when
using an u64 variable in C code, when compiling with the latest CSL
compiler with the new ARM EABI.

Why does the ARM926 require 64-bit alignment?
