sail - Formal specification language for ISAs

Age	Commit message (Collapse)	Author
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.
2014-07-14	Initial support for aliases and exit through the type system and the ↵	Kathy Gray
	interpreter. An alias can be read within the interpreter, but not written to. Exits aren't yet taken in the interpreter.
2014-07-03	Introduce a Sail library	Gabriel Kerneis
	Used by the Power XML extraction tool.
2014-06-12	Add uint* to default type names for lexer	Gabriel Kerneis
	This is necessary to avoid a parse error. It might make sense to merge this list and the one in type_internal.ml somehow, to avoid duplication and similar bugs in the future.
2014-03-31	Extend constraint checking, and add casts for base of a vector shifts (i.e. ↵	Kathy Gray
	from 0 to 32 etc, doesn't change order yet.).
2014-03-26	Steps towards solving constraints	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.
2014-02-03	More type checking, including coercing 0 and 1 into bits when appropriate ↵	Kathy Gray
	(in limited circumstances at the moment due to which expressions are actually checked, so test files should not yet be changed)
2014-01-17	Type check through type definitions and val specifications, building ↵	Kathy Gray
	definition environment. Skipping function definition, let bind, and expression checking for this commit (to come).
2013-11-28	Updated syntax with working examples	Kathy Gray

2013-11-27	More front-end passes for type identifiers	Kathy Gray

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).
2013-10-10	Rename Ast to Interp_ast for the interpreter	Gabriel Kerneis

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

2013-08-20	Set some initial kind environments; start pretty printing	Kathy Gray

2013-08-08	More forms converting from parse_ast to ast; also removed some annot aux ↵	Kathy Gray
	homs for terms that only need locations and not full annotations
2013-08-07	Starting checks and translation from parse_ast to ast, including an internal ↵	Kathy Gray
	representation of types to support unification; importing support modules from Lem including pp and util
2013-08-01	Lex and discard comments	Gabriel Kerneis

2013-07-31	Adding reporting basic from Lem development, also adding basic error ↵	Kathy Gray
	messages for syntax and lexical errors (i.e. syntax error and location information)
2013-07-26	Remove white space/terminal tracking	Kathy Gray

2013-07-25	Clean trailing whitespace	Gabriel Kerneis

2013-07-24	Parser compiles and compiles some very small test programs.	Kathy Gray
	Output is only given in the event of a parse or lex failure (with poor reporting for now) There are still 10 shift/reduce conflicts that may need further investigating and a few syntax changes that need discussion.
2013-07-12	Parser in progress, and more src files for plumbing parsing, lexing and ↵	Kathy Gray
	eventual type checking together
