The emitter assumes it has access to a token stream; in order to implement AST reflection, refactor the compiler so that it's possible to emit code from an AST that doesn't have an associated token stream. struct JSSourceCompiler : JSCompiler struct JSAstCompiler : JSCompiler Patch forthcoming.

First attempt. Currently breaks tests: ecma_5/strict/11.3.1.js ecma_5/strict/11.3.2.js ecma_5/strict/11.4.4.js ecma_5/strict/11.4.5.js ecma_5/strict/11.13.1.js ecma_5/strict/11.13.2.js ecma_5/strict/12.2.1.js ecma_5/strict/12.14.1.js ecma_5/strict/13.1.js ecma_5/strict/regress-532254.js js1_5/Regress/regress-352197.js js1_8_1/strict/12.2.1.js js1_8_1/strict/generator-eval-arguments.js js1_8_1/strict/let-block-eval-arguments.js Most of these problems seem to be one bug: it's not enabling strict mode correctly.

All tests pass now. Still seems to have an error-display bug: doesn't print out the source line of the error anymore.

OK, fixed the bug where it wasn't reporting the source line of errors. And got rid of some dead comments. There's one XXX_dherman for review: I'm not sure what the proper ownership story is for JSCodeGenerator::filename.

uh, I didn't realize this was a 300k patch. We should probably run it through the benchmark Leary put together in bug 548621, just to be safe.

No argument here; I definitely want my work checked. Thanks, Dave

My apologies for the portly patch. I'm splitting this up into a number of smaller patches-- note the new dependencies on bug 518055, bug 550629, bug 550350, and bug 550630. Dave

Obsoleted by bug 558437. Dave
