| 8e82d8d | Mihai Bazon | 11 September 2012, 12:42:28 UTC | fixed 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 | 11 September 2012, 12:42:28 UTC |

| 8633b00 | Mihai Bazon | 05 September 2012, 08:31:02 UTC | cleaned 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). | 05 September 2012, 08:39:43 UTC |

| 376667a | Mihai Bazon | 04 September 2012, 10:20:28 UTC | more 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). | 04 September 2012, 10:20:28 UTC |
