[PATCH v4 03/16] powerpc: Use a datatype for instructions

2020-03-19 Thread Jordan Niethe
Currently unsigned ints are used to represent instructions on powerpc. This has worked well as instructions have always been 4 byte words. However, a future ISA version will introduce some changes to instructions that mean this scheme will no longer work as well. This change is Prefixed
