| 2015-05-13 | Add dynamic footprint dependency check event/outcome | Kathy Gray | |
| Also fix type checker bug in not reporting modifications to parameter values | |||
| 2015-03-26 | Add subtraction to nexp grammar (removing the need to do a + (-1 * b)) | Kathy Gray | |
| Fix up parsing on 2** precedence Fix errors on type variables in function definition | |||
| 2015-02-17 | Bring type rules more into modern state of type checker | Kathy Gray | |
| 2015-02-13 | Actually use new dependency information in generation of lem/etc. | Kathy Gray | |
| Also stop rewriting code in the pretty printer, instead move it all into a new general rewriting pass | |||
| 2015-01-12 | Add specialised support for numeric singleton types (i.e. what used to be ↵ | Kathy Gray | |
| range<'N,'N>) Non-sugar syntax is -- forall Nat 'N. atom<'N> Sugar syntax is -- [: 'N :] Also begin adding pp support for generating ocaml from ast types. | |||
| 2014-12-03 | Type rules unto coercion now represented in ott | Kathy Gray | |
| 2014-11-27 | Start having a manual of sorts. At least specify the built in functions | Kathy Gray | |
| (list not complete) | |||
| 2014-09-30 | Add type annotations to funcls to track effects and constraints from one ↵ | Kathy Gray | |
| function-clause | |||
| 2014-07-29 | A file can now declare that a default order is either inc or dec, and this ↵ | Kathy Gray | |
| will be reflected in short hand type syntax, inc is still the default if undeclared So: default order dec register bit[32] t (* Declares t as a decreasing vector, starting at 31 on the left and decreasing to 0 *) default order inc register bit[32] o (* Declares o as an increasing vector, starting at 0 on the left and increasing to 31 *) It is presently possible to change the default mid-file; this is almost certainly bad and I will turn it into an error soon. | |||
| 2014-07-18 | Writing to concatenated aliases | Kathy Gray | |
| 2014-07-08 | Extend language to support register aliases and to support interrupts, traps ↵ | Kathy Gray | |
| and the like. | |||
| 2014-06-26 | Adding better support for unspecified values in indexed vectors | Kathy Gray | |
| Also begining to add support for nondeterministic blocks and cleaning up some of the Many warnings on pattern matches | |||
| 2014-06-25 | Add support for memory barrier | Kathy Gray | |
| 2014-06-25 | Add support for actions that read just a slice or single bit of a register | Kathy Gray | |
| 2014-06-04 | Fixup type coercions and overloading | Kathy Gray | |
| Reduce the number of implicit coercions we're doing, expanding overloading and fixing up types of functions. Warning: test_power does not run as not all overloaded funcitons are implemented Warning: vector concatenation does not pretty print to sail source yet | |||
| 2014-05-14 | More interface update for connecting externally (interp_interface provides ↵ | Kathy Gray | |
| functions for connecting the interpreter to a memory model) Also adding default values to index vectors for supporting sparse vectors/maps | |||
| 2014-04-08 | Reduce redundant information in AST | Kathy Gray | |
| 2014-04-02 | Solve more constraints; fix up test suite bugs uncovered by solving more ↵ | Kathy Gray | |
| constraints. Clean up Lem output a little for readability while debugging. | |||
| 2014-04-01 | Allow negative "nat" internally | Gabriel Kerneis | |
| to_num and to_vec probably still need to be fixed | |||
| 2014-03-27 | Check simple constraints (i.e. ones using only constants). | Kathy Gray | |
| Changes syntax of tuple type from * to , so that nexps of the form 8 * 'n can be supported in the parser, which was apparently not true before. | |||
| 2014-03-26 | More steps towards solving and using constraint information | Kathy Gray | |
| 2014-03-03 | Fixing assorted bugs. Adding ability to put a type on the identifier being ↵ | Kathy Gray | |
| assigned to in assignments. | |||
| 2014-02-28 | Correct bug in parsing and handling a['a:'b] types | Kathy Gray | |
| 2014-02-21 | Add type annotations to lem grammar, including printing out the annotated ↵ | Kathy Gray | |
| ast, and extending the interpreter to expect annotations. Annotations and locations are still not used by the interpreter. | |||
| 2014-02-18 | Add function's name for external tag, using register when a register | Kathy Gray | |
| 2014-02-18 | Adding explicit order to for loops | Kathy Gray | |
| 2014-02-14 | update syntax of vector slicing. | Kathy Gray | |
| 2014-02-12 | Change nat to natural in ott | Kathy Gray | |
| Type checking now recurses through assign, but doesn’t do the proper checks yet | |||
| 2014-01-07 | lem homs and type headers | Kathy Gray | |
| 2013-12-17 | Convert coerce to a relation that generates a new expression, inserting ↵ | Kathy Gray | |
| coercion function calls where applicable. | |||
| 2013-12-10 | Fixed bug in interpreter | Kathy Gray | |
| 2013-12-03 | Syntax changes per discussion with Peter, as well as L2.ott document clean up. | Kathy Gray | |
| Could not at this time return lists to [| |] from [|| ||] as the parser cannot distinguish a cast with enum’s syntactic sugar from the start of a parenthesised list (i.e. ( [|3|] ) And there are still conflicts with moving enums to [3], so those changes can’t be pushed in with current parser technology. | |||
| 2013-11-29 | Push syntax changes to type rules | Kathy Gray | |
| 2013-11-28 | Updated syntax with working examples | Kathy Gray | |
| 2013-11-22 | Syntax changes per discussions on Thursday. | Kathy Gray | |
| First pass parser to identify type names is in progress (current test files fail, will correct once pre-parser is in place) | |||
| 2013-11-07 | Port L2 to new Lem | Gabriel Kerneis | |
| Tests compile and run properly. There is a lot of hackery going on to workaround the rough edges of new Lem. Use at your own risk (you need the "library-format" branch of lem). | |||
| 2013-11-07 | Most of the function type system | Kathy Gray | |
| 2013-11-01 | Moved metatheory grammars into l2_rules.ott | Kathy Gray | |
| Added val extern specification to language, parser, printer, and interpreter Added various def level type system support, expressions type system in place Except for assignment | |||
| 2013-10-25 | More type rules | Kathy Gray | |
| 2013-10-23 | Thread type environment through expressions because of block adding new ↵ | Kathy Gray | |
| variables, say in each branch of an if, that we want to be visible beyond it. | |||
| 2013-10-23 | Don't export list of types to ML AST | Gabriel Kerneis | |
| 2013-10-18 | Typeing rules for patterns and easy expressions | Kathy Gray | |
| 2013-10-11 | Supporting all expressions, although vector cacentation pattern matching can ↵ | Kathy Gray | |
| only match simple patterns (until type information is available). | |||
| 2013-10-09 | Adding memory writes. Cleaning up the let in the ott file to reflect what ↵ | Kathy Gray | |
| actually parses | |||
| 2013-10-09 | extend language of lexp to include memory writes | Kathy Gray | |
| 2013-09-26 | Adding undefined | Kathy Gray | |
| Also interpreter now supports reading and writing of basic registers (i.e with no subranges yet) | |||
| 2013-09-09 | Fixes bugs in pretty printer to generate legal lem syntax; split ott grammar ↵ | Kathy Gray | |
| and rules for lem ast generation; created a new directory for the lem interpreter and moved the Lem ast to it. | |||
| 2013-09-09 | Pretty printer to Lem ast added; accessed by -lem_ast on the command line | Kathy Gray | |
| 2013-09-05 | workaround likely aux rule bug | Peter Sewell | |
| 2013-09-05 | More type checking, and trying to generate Lem from the ott | Kathy Gray | |
