When reversing Operating Systems on ARM, it is quite common to see machine-specific-registers (MSR) being used. However, IDA doesn't have a builtin database for those, and instead displays cryptic sequences:. Past solutions include Brandon Azad's script to add comments to these instructions. However, it takes a while for these script to run and you will need to run it again upon marking new data as code. This plugin attempts to solve this problem by hooking into functions that are responsible for displaying instructions in IDA. The result is that these cryptic sequences are replaced with standard MSR names... IDA caches these printing so the hook is generally only invoked once every session. The performance overhead is generally unnoticable. The plugin left the commas behind in order to avoid corrupting disassembler's data. I haven't had a problem with doing that; however, I decided not to in order to avoid corruptions.
