In my efforts to create a formal specification of the Arm architecture, I have focussed on the parts written in “pseudocode”. I have reverse engineered the ASL language hiding inside the pseudocode to create a formal, executable specification that I can execute and test. In the process, I have tended to ignore all the natural language prose that makes up the bulk of the 6,000 page Arm Architecture Reference Manual. In defiance of Betteridge’s Law, this article is going to explain how I finally found a use for all that prose.
