sail - Formal specification language for ISAs

Age	Commit message (Collapse)	Author
2014-05-29	Check constraints in power.sail; this required using big_int instead of int ↵	Kathy Gray
	to support 264. Note: now nat (short hand for range<0,infinity>) should only be used if you really mean a nat instead of a bounded number (i.e. range<0,232>)
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
2014-03-26	More steps towards solving and using constraint information	Kathy Gray

2014-03-11	Change treatment of type abbreviations so that name and full type are ↵	Kathy Gray
	available for field lookups of registers; this feature still not fully working.
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	Adding explicit order to for loops	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

2013-12-10	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).
2013-11-01	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
2013-10-23	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
2013-10-04	Clean up build system	Gabriel Kerneis
