2012-09-11fixed some mess with symbols/scope...- all symbols now have a `thedef` property which is a SymbolDef object, instead of the `uniq` that we had before (pointing to the first occurrence of the name as declaration). - for undeclared symbols we still create a SymbolDef object in the toplevel scope but mark it "undeclared" - we can now call figure_out_scope after squeezing, which is useful in order not to mangle names that were dropped by the squeezer Mihai Bazon
2012-09-11checkpoint...- discard statements with no side effects (unsafe? could be) - safer hoist_vars (needs some revamping of scope/mangling) Mihai Bazon
2012-09-10hoist_vars is pretty bad, it seems. cancelled it for now.Mihai Bazon

2012-09-05support for hoisting declarations...and finally it seems we beat v1 in terms of compression Mihai Bazon
2012-09-05cleaned up usage of AST_BlockStatement...The following nodes were instances of AST_BlockStatement: AST_Scope, AST_SwitchBlock, AST_SwitchBranch. Also, AST_Try, AST_Catch, AST_Finally were having a body instanceof AST_BlockStatement. Overloading the meaning of AST_BlockStatement this way turned out to be a mess; we now have an AST_Block class that is the base class for things having a block of statements (might or might not be bracketed). The `this.body` of AST_Scope, AST_Try, AST_Catch, AST_Finally is now an array of statements (as they inherit from AST_Block). Avoiding calling superclass's _walk function in walkers (turns out we walked a node multiple times). Mihai Bazon

2012-09-04more fiddling with boolean expressions, etc....optimize away while(false), and transform while(true) ==> for(;;). UNSAFE: some expressions are optimized away when we're in boolean context and can determine that the value will always be true or false. For example: x() || true ==> always `true` in boolean context x() && false ==> always `false` in boolean context It's not technically correct to drop these expressions since we drop the function call too (that might have side effects); on the other hand, I can't see any legitimate use for such expressions and they might simply indicate a bug (we do warn about it).

2012-09-03a LabeledStatement should be in fact a StatementWithBody...This fixes output for: if (foo) { moo: if (bar) { break moo; } } else { baz(); } (the labeled statement must be outputted inside brackets) Mihai Bazon
2012-09-03declare boolean optionsMihai Bazon
2012-09-03switch branches must be declared `required` so that the compressor doesn't...replace nodes with a single statement. looks stable for now, though mess begins to sink in. need to review the AST hierarchy. Mihai Bazon
2012-09-03Reverting "minor perf. improvements"...Revert "minor perf. improvements" This reverts commit 24bfd55a22afd791d4a97694641831cfbd27fb14. broke the parser somehow; too early to optimize, let's get the other stuff running. Mihai Bazon

2012-08-28fix code generator for this case:...if (foo) { with (bar) if (baz) x(); } else y(); (the compressor removes the brackets since the consequent consists of a single statement, but the codegen must include the brackets because otherwise the `else` would refer to the inner `if`) Mihai Bazon
