2017-12-19Support user-defined exceptions in Lem shallow embeddingThomas Bauereiss
The type-checker already supports a user-defined "exception" type that can be used in throw and try-catch expressions. This patch adds support for that to the Lem shallow embedding by adapting the existing exception mechanisms of the state and prompt monads. User-defined exceptions are distinguished from builtin exception cases. For example, the state monad uses type ex 'e = | Exit | Assert of string | Throw of 'e to distinguish between calls to "exit", failed assertions, and user-defined exceptions, respectively. Early return is also handled using the exception mechanism, by lifting to a monad with "either 'r exception" as the exception type, where 'r is the expected return type and "exception" is the user-defined exception type.

2017-12-06Make AST after rewriting for Lem backend type-checkableThomas Bauereiss
- Add support for some internal nodes to type checker - Add more explicit type annotations during rewriting - Remove hardcoded rewrites for E_vector_update etc from Lem pretty-printer; these will be resolved by the type checker during rewriting now

2017-08-24Begin refactoring Sail libraryThomas 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.
