| 2017-08-24 | Improve and simplify handling of mutable local variables | Thomas Bauereiss | |
| 2017-08-24 | Begin refactoring Sail library | Thomas Bauereiss | |
| - Add back support for bit list representation of bit vectors, for backwards compatibility in order to ease integration with the interpreter. For this purpose, split out a file sail_operators.lem from sail_values.lem, and add a variant sail_operators_mwords.lem for the machine word representation of bitvectors. Currently, Sail is hardcoded to use machine words for the sequential state monad, and bit lists for the free monad, but this could be turned into a command line flag. - Add a prelude_wrappers.sail file for glueing the Sail prelude to the Lem library. The wrappers make use of sizeof expressions to extract type information from bitvectors (length, start index) in order to pass it to the Lem functions. - Add early return support to the free monad, using a new constructor "Return of 'r". As with the sequential monad, functions with early return are wrapped into "catch_early_return", which extracts the return value at the end of the function execution. | |||

| 2017-08-08 | Glue together Sail prelude and Lem library | Thomas Bauereiss | |
| 2017-06-21 | Pretty-print bitvector expressions | Thomas Bauereiss | |
| - Add case distinctions between bitvector types and vectors of other element types (e.g. registers) and use the corresponding operations (i.e. "bvslice", "bvaccess", etc for the former, and "slice", "access", etc for the latter) when pretty-printing expressions - Add type annotations to expressions when the type includes bitvectors with concretely known length - Update state.lem to use bitvectors (in the interface, at least; internally, bitvectors are still stored as bit lists for now, since that makes it easier to support storing different registers with different lengths) This has been tested with the CHERI-MIPS model with some success, but some things are still missing: - Bitvector patterns are not handled yet - Some bitvector length monomorphisation is needed in a few places of the model - Some type annotations are missing, because the (old) Sail type checker does not infer bitvector lengths in some instances where one would hope it to do that; this should be checked with the new type checker | |||
