15 unaligned accesses, why you need to write code that doesn't cause them,
19 The definition of an unaligned access
22 Unaligned memory accesses occur when you try to read N bytes of data starting
25 reading 4 bytes of data from address 0x10005 would be an unaligned memory
52 Why unaligned access is bad
55 The effects of performing an unaligned memory access vary from architecture
59 - Some architectures are able to perform unaligned memory accesses
61 - Some architectures raise processor exceptions when unaligned accesses
62 happen. The exception handler is able to correct the unaligned access,
