It seems potentially a "call for help":<p>"I appreciate help if this is the kind of rabbit hole you'd like to burrow in."<p>The current status is of the conversion:<p>"a lot of instructions being generated are invalid and the code generator has to be reviewed."<p>If it is, and the author is reading this, I suggest documenting exactly one by one the open issues. There are surely readers here that are able to "see" and propose a fix for some details without investing a lot of energy upfront to first figure out what the issues are.
