| 2017-03-27 | handle overlapped variable definitions (#1691)...Process variable definitions with or without assigned values against: - `arguments` - named function arguments - multiple definitions within same scope Essentially demote variable declarations with no value assignments. Also fixed invalid use of `AST_VarDef` over `arguments` - should use a member of `AST_SymbolDeclaration` instead. | Alex Lam S.L |
| 2017-03-26 | fix `delete` related issues in `collapse_vars` and `reduce_vars` (#1689) | Alex Lam S.L |
| 2017-03-25 | fix `reduce_vars` on `AST_Switch` (#1671)...Take conditional nature of switch branches into account. fixes #1670 | Alex Lam S.L |
| 2017-03-19 | make `expect_stdout` work on Node.js 0.12 (#1623)...That particular version of Node.js has messed up error messages, so provide a version-specific workaround. Also fixed an formatting issue which would cause `expect_stdout` to fail if error message contains excerpts of input. Apply `expect_stdout` to more applicable tests. | Alex Lam S.L |
| 2017-03-16 | fix `hoist_vars` on `reduce_vars` (#1607)...`hoist_vars` converts variable declarations into plain assignments, which then confuses `reduce_vars` fixes #1606 | Alex Lam S.L |
| 2017-03-11 | disallow parameter substitution for named IIFEs (#1596)...Self-referenced function has non-fixed values assigned to its parameters. Let `unused` & `!keep_fnames` do the scanning, then apply `reduce_vars` only to unnamed functions. fixes #1595 | Alex Lam S.L |
| 2017-03-09 | fix & improve function argument compression (#1584)...- one-use function call => IIFE should take `eval()` & `arguments` into account - if unused parameter cannot be eliminated, replace it with `0` fixes #1583 | Alex Lam S.L |
| 2017-03-08 | fix function name eliminiation (#1576)...Function expression can be assigned to a variable and be given a name. Ensure function name is the reduced variable before clearing it out. fixes #1573 fixes #1575 | Alex Lam S.L |
| 2017-03-07 | fix deep cloning of labels (#1565)...`AST_Label.references` get `.initialize()` to `[]` every time after `.clone()` So walk down the tree to pick up the cloned `AST_LoopControl` pieces and put it back together. | Alex Lam S.L |
| 2017-03-07 | transform function calls to IIFEs (#1560)...- expose function body to call sites for potential optimisations - suppress substitution of variable used within `AST_Defun` | Alex Lam S.L |
| 2017-03-07 | avoid substitution of global variables (#1557)...- unless `toplevel` is enabled - global `const` works as before | Alex Lam S.L |
| 2017-03-05 | handle variable declaration within catch blocks (#1546)...accounts for IE8- scoping | Alex Lam S.L |
| 2017-03-03 | properly cover all cases of for-in loop variables (#1536) | Alex Lam S.L |
| 2017-03-03 | fix reference marking in for-in loops (#1535)...fixes #1533 | Alex Lam S.L |
| 2017-03-02 | fix corner cases in `reduce_vars` (#1524)...Avoid variable substitution in the following cases: - use of variable before declaration - declaration within conditional code blocks - declaration within loop body fixes #1518 fixes #1525 | Alex Lam S.L |
| 2017-02-26 | consolidate `evaluate` & `reduce_vars` (#1505)...- improve marking efficiency - apply smarter `const` replacement to `var` fixes #1501 | Alex Lam S.L |
| 2017-02-21 | improve reduce_vars and fix a bug...- update modified flag between compress() passes - support IIFE arguments - fix corner case with multiple definitions closes #1473 | alexlamsl |
| 2017-01-26 | optimise binary operands with evaluate() (#1427)...- remove call to evaluate() in is_constant() and let nested optimize() does its job instead - reject RegExp in is_constant() and remove special case logic under collapse_vars - operands to conditionals optimisation are now always evaluate()-ed - throw error in constant_value() instead of returning undefined to catch possible bugs, similar to make_node_from_constant() - optimise binary boolean operators under `evaluate` instead of `conditionals` | Alex Lam S.L |
| 2017-01-26 | augment evaluate to extract within objects (#1425)...- gated by `unsafe` - replaces previous optimisation specific to String.length - "123"[0] => 1 - [1, 2, 3][0] => 1 - [1, 2, 3].length => 3 - does not apply to objects with overridden prototype functions | Alex Lam S.L |
| 2016-10-01 | Optimize unmodified variables | alexlamsl |
