sail - Formal specification language for ISAs

Age	Commit message (Collapse)	Author
2016-01-06	Add new assert expression to Sail	Kathy Gray
	This splits the former functionality of exit into errors, which should now use assert(bool,option<string>), and a means of signalling actions such as instruction-level exceptions, interrupts, or other features that impact the ISA. The latter will now be tracked with an effect escape, and so any function containing exit and declared pure will generate a type error. WARNING: ARM spec will not build with this commit until I modify it. MIPS spec will not build with this commit until modified.
2015-11-24	Add BE_escape effect when an E_exit is seen	Kathy Gray
	Close #20
2015-10-19	progress on lem backend	Christopher Pulte

2015-10-08	Add another internal let for Christopher	Kathy Gray

2015-10-07	Start expanding annot for more refined effect tracking	Kathy Gray

2015-09-24	Parameterise the rewriter's for multiple different rewritings	Kathy Gray
	Add a new internal node for moving assignments into scope-preserving expressions that more explicitly define the scope
2015-06-24	Support new memory write events in the sail front end and pretty printer	Kathy Gray
	Events are eamem to signal the memory address to write to and wmv to pass the value to write
2015-05-13	Add dynamic footprint dependency check event/outcome	Kathy Gray
	Also fix type checker bug in not reporting modifications to parameter values
2015-05-09	towards buildability - l2.ml and l2_parse.ml as regenerated with current Ott	Peter Sewell

2015-05-09	use less confusing Ott binary	Peter Sewell

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
2015-02-13	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
2014-09-30	Add type annotations to funcls to track effects and constraints from one ↵	Kathy Gray
	function-clause
2014-08-13	Kathy, Peter tweak Makefile for interactive demo and src/myocamlbuild.ml to ↵	Peter Sewell
	temporarily use other version of Lem
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

2014-06-04	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

2014-03-26	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	Adding explicit order to for loops	Kathy Gray

2014-01-07	lem homs and type headers	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)
2013-11-01	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
