OVERVIEW



JSC (JavaScript Compiler) is a stand-alone front-end implementation

of the JS2 language specification. Its purpose is to demonstrate how

JS2 programs are statically prepared for execution by a JS2 interpreter. 

Its output is a psuedo intermediate language suitable for reading by

human beings.

Its output is assembly code that is assembled by the JS engine.

STATUS OF JSC



Dec-1-2000

----------

Signficant portions of the type system, compile-time constant evaluator,

and name management systems are working. Missing are semantics for 

using, import, export, and unit parsing. More tests are also needed.





ISSUES



* Intermediate form of references, classes, and interfaces.



CHANGES



Jan-26-2001

-----------

Added first cut at xml icode generation. In particular function definitions,

call and binary expressions are implemented. Object and array literals are

also implemented. Many of the tests used for verifying the parser and semantic

analyzer, are not yet working.



Dec-15-2000

-----------

Removed dependency on sun.tools packages.
