2020-03-19Improve a particularly unhelpful type errorAlasdair
From: No type variable 'ex14# to: Type error: [../and_let_bool.sail]:6:19-50 6 | and_bool(let y : bool = x in not_bool(y), x) | ^-----------------------------^ | The type variable 'ex14# would leak into an outer scope. | | Try adding a type annotation to this expression. | This error was caused by: | [../and_let_bool.sail]:6:23-24 | 6 | and_bool(let y : bool = x in not_bool(y), x) | | ^ | | Type variable 'ex14# was introduced here |
2020-03-18Add documentation for CLion/PyCharm/IntelliJ syntax highlightingAlex Richardson
Turns out the TextMate Bundles plugin can load the vscode extension and provide some basic syntax highlighting.
2020-03-18Expose details of failed lexp bounds checksThomas Bauereiss
Allows ASL-to-Sail translation to automatically patch lexp bounds check errors.

2020-02-21Add barriers to regfp.sail for full ARMv8Alasdair Armstrong
Again use an $ifdef to avoid breaking RMEM. We can't use the same barrier_kind, because we *really* want a plain enumeration both for its simple SMT representation and a simple 1 to 1 mapping to the cat models used by herd. Technically for Isla, all the read_kind/write_kind/barrier_kind etc types can be defined separately on a per-architecture basis anyway, so maybe using this file at all is a bit of an anachronism.
2020-02-21Make sure we test that struct literals have a complete set of fields. Fixes #60Alasdair Armstrong
2020-02-21Distinguish type identifiers in topological sortingThomas Bauereiss
Fixes #61
2020-02-21Fix bug in last patch to topological sorting (e5ee087f)Thomas Bauereiss
2020-02-21SMT: Implement a few more primopsThomas Bauereiss
2020-02-21Nl_flow: Consider early returnsThomas Bauereiss
Tells the typechecker that, for example, in a block after if (i < 0) then { return (); } else { ... } the constraint not(i < 0) holds. This is a useful pattern when type-checking code generated from ASL.
2020-02-21Move topological sorting code to graph.mlThomas Bauereiss
2020-02-20More list C codegen fixes for issue #59Alasdair Armstrong
2020-02-20Fix missing code generation builtins for lists. Fixes #59Alasdair Armstrong
Also uncovered a few other issues w.r.t lists

2020-02-06Make sure tdiv_int and tmod_int are recognised by sail -iAlasdair Armstrong
2020-02-05Tweak Coq scopes for 8.11Brian Campbell
2020-02-03Add an __instr_announce builtin in regfp.sailAlasdair Armstrong
Allows keeping track of which instructions actually get executed in a trace
2020-02-03Update regfp.sail with ifetch changes from poly_mapping branchAlasdair Armstrong
However, use an ifdef to make sure the ifetch changes only appear for the ARM spec, because otherwise the generated lem for RMEM will break.
2020-01-31Fix soundness bug found by MarkAlasdair
When returning a type from a letbinding we need to be careful that the type it returns does not refer to any type variable that only exists for the lifetime of the letbinding (because it was bound by it). Normally this fails because any type variable bound in the inner letbinding won't exist in the outer scope, but if it is shadowed this can cause an issue.
2020-01-30Make sure external pprint is listed as a dependency for sail when used as an ↵Alasdair Armstrong

2020-01-21Reduce the amount of unnecessary parentheses in Coq outputBrian Campbell
2020-01-21Use hex/bin literals in Coq backendBrian Campbell
Also be more careful to avoid pattern bindings with identifiers to avoid parsing clashes, eg `let 'bytes := ...` which is confused with the notation for binary literals.

Useful for tracking down non-determinism
2020-01-16Allow effects on mappingsAlasdair Armstrong
2020-01-16Cleanup type-checking rule for LEXP_fieldAlasdair Armstrong
Was being overly conservative with nested structs and used an incorrect location for the error message
