2017-11-11implement compress option `reduce_funcs` (#2466)Alex Lam S.L
- inline single-use function declarations as expressions when permissible - depend on `reduce_vars` - enabled by default - disable for speed critical code fixes #2464

fixes #2233
2017-05-27extend `node_version` range on applicable tests (#2015)Alex Lam S.L
2017-05-26fix `dead_code` on block-scoped `function` under "use strict" (#2006)Alex Lam S.L
Technically not part of ES5, but commonly used code exists in the wild.
2017-05-14fix bugs with getter/setter (#1926)Alex Lam S.L
- `reduce_vars` - `side_effects` - property access for object - `AST_SymbolAccessor` as key names enhance `test/ufuzz.js` - add object getter & setter - property assignment to setter - avoid infinite recursion in setter - fix & adjust assignment operators - 50% `=` - 25% `+=` - 2.5% each for the rest - avoid "Invalid array length" - fix `console.log()` - bypass getter - curb recursive reference - deprecate `-E`, always report runtime errors
2017-05-12remove support for `const` (#1910)Alex Lam S.L
As this is not part of ES5.
2017-03-30optimize try-catch-finally (#1731)Alex Lam S.L
- eliminate empty blocks - flatten out if try-block does not throw
2017-03-19make `expect_stdout` work on Node.js 0.12 (#1623)Alex Lam S.L
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.
2017-03-07avoid substitution of global variables (#1557)Alex Lam S.L
- unless `toplevel` is enabled - global `const` works as before
2017-02-28warn & drop `#__PURE__` iff IIFE is dropped (#1511)Alex Lam S.L
- consolidate `side-effects` optimisations - improve string `+` optimisation - enhance literal & `conditionals` optimisations
2017-02-24enable `collapse_vars` & `reduce_vars` by defaultalexlamsl
- fix corner cases in `const` optimisation - deprecate `/*@const*/` fixes #1497 closes #1498

closes #1487
2016-01-20Tighten up @const regex.Samuel Reed
2016-01-20Use TreeWalker for more accurate @const results and update testsSamuel Reed
2016-01-19Mark vars with /** @const */ pragma as consts so they can be eliminated.Samuel Reed
Fixes older browser support for consts and allows more flexibility in dead code removal.
2015-02-11Clean up unit test breakageRichard van Velzen
In 992b6b9fcce47ca67ecb14675f10b172ce7a99b5 unit test broke (which I missed). This was due to undeclared variables not being side-effects free. However, since they're really not side-effect free, just declare them in the test cases.
2012-09-07always keep declarations found in unreachable codeMihai Bazon
a few more tests and some cleanups.
