They only require HOL4; the necessary Lem library files are included. +A recent checkout of HOL4 from the repository at +<https://github.com/HOL-Theorem-Prover/HOL/> is required. This snapshot was +successfully built with commit `7ed3f12`, for example. Some older versions +will fail with a Holdep error due to a lexer bug in HOL that has now been +fixed. + Note that HOL4 takes a substantial amount of time to process the definition of the `regstate` record. In particular, allow over an hour for the MIPS model. |
