This document describes a new implementation of CMU Common Lisp (nee Spice Lisp) as it is implemented on the IBM RT PC running Mach, a Berkeley Unix 4.3 binary compatible operating system. This design is undergoing rapid change, and for the present is not guaranteed to accurately describe any past, present, or future implementation of CMU Common Lisp. All questions and comments on this material should be directed to David B. McDonald (David.McDonald@CS.CMU.EDU).
This document specifies the hand-coded assembler routines (miscops) and virtual memory architecture of the IBM RT PC CMU Common Lisp system. This is a working document, and it will change frequently as the system is developed and maintained. If some detail of the system does not agree with what is specified here, it is to be considered a bug.
