2017-03-08fix 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 #1575Alex Lam S.L
2017-03-08only run benchmark & jetstream on CI (#1571)Alex Lam S.L
2017-03-08plan B for IE8 do-while semi-colon fix (#1572)...- omitting trailing semi-colon in do-while breaks non-browser parser, e.g. uglify-js 1.x - trailing semi-colon only breaks IE8 if followed by `else` or `while` - always use braces in do-while body to workaround 2nd case with no size loss in compression fixes #1568Alex Lam S.L
2017-03-08fix return from recursive IIFE (#1570)...`side-effects` did not account for IIFEs being able to reference itself thus making its return value potentially significantAlex Lam S.L
2017-03-07v2.8.8Alex Lam S.L
2017-03-07include benchmark.js in test suite (#1564)...- report file sizes and overall run time - exit with non-zero code upon errorAlex Lam S.L
2017-03-07fix 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
2017-03-07transform 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
2017-03-07avoid substitution of global variables (#1557)...- unless `toplevel` is enabled - global `const` works as beforeAlex Lam S.L
2017-03-07collapse_vars: do not replace a constant in loop condition or init (#1562)kzc
2017-03-06suppress semicolons after do/while (#1556)...- unless both `beautify` & `screw-ie8` are enabled - deprecate workaround for if-do-while-else fixes #186Alex Lam S.L
2017-03-05v2.8.7Alex Lam S.L
2017-03-05fixup for #1553 (#1555)...- `++a` is the one that is foldable - transform `a++` into `++a` for better optimisationAlex Lam S.L
2017-03-05v2.8.6Alex Lam S.L
2017-03-05collapse assignment with adjacent subsequent usage (#1553)...- consolidate `cascade` optimisations - support ++/-- postfixes - remove redundant optimisation identified in #1460 fixes #368Alex Lam S.L
2017-03-05handle variable declaration within catch blocks (#1546)...accounts for IE8- scopingAlex Lam S.L
2017-03-05improve `unsafe` on undefined (#1548)...`unsafe` turns undefined keyword into a variable of the same name if found, but that interferes with other related optimisations. Keep track of such transformations to ensure zero information loss in the process.Alex Lam S.L
2017-03-05stay safe with constants in IE8- (#1547)...- `undefined` etc. can be redefined at top-level for IE8-, so disable related optimisations - fixed `--support-ie8` catch mangle bugAlex Lam S.L
2017-03-05fix handling of shebang and preamble (#1545)...fixes #1332Alex Lam S.L
2017-03-05fix a corner case in #1530 (#1552)Alex Lam S.L

2017-03-04disallow collapse_vars constant replacement in for-in statements (#1543)kzc
2017-03-03process code with implicit return statement (#1522)...Bookmarklet for instance implicitedly assumes a "completion value" without using `return`. The `expression` option now supports such use cases. Optimisations on IIFEs also enhanced. fixes #354 fixes #543 fixes #625 fixes #628 fixes #640 closes #1293Alex Lam S.L
2017-03-03compress numerical expressions (#1513)...safe operations - `a === b` => `a == b` - `a + -b` => `a - b` - `-a + b` => `b - a` - `a+ +b` => `+b+a` associative operations (bit-wise operations are safe, otherwise `unsafe_math`) - `a + (b + c)` => `(a + b) + c` - `(n + 2) + 3` => `5 + n` - `(2 * n) * 3` => `6 * n` - `(a | 1) | (2 | d)` => `(3 | a) | b` fixes #412Alex Lam S.L
2017-03-03facilitate fix for #1531 (#1542)Alex Lam S.L
2017-03-03v2.8.5Alex Lam S.L
2017-03-03fix chained assignment with `unused` (#1540)...When #1450 optimises `a=b=42`, it stops after the first variable even if both are unused. fixes #1539Alex Lam S.L
2017-03-03collapse_vars should not replace constant in for-in init section (#1538)...fixes #1537kzc
2017-03-03properly cover all cases of for-in loop variables (#1536)Alex Lam S.L

2017-03-02trim unused invocation parameters (#1526)Alex Lam S.L
2017-03-02minor improvement to string optimisation (#1514)...- "" + "a" => "a" - "" + a + "b" => a + "b" - "a" + "" => "a" (improving on #45)Alex Lam S.L
2017-03-02v2.8.4Alex Lam S.L
2017-03-02fix 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 #1525Alex Lam S.L
2017-03-01v2.8.3Alex Lam S.L
2017-03-01fix crash on missing `props` to `string_template()` (#1523)...Patched up `make_node()` without `orig`. There may be other cases where `start` could be missing, so make it print "undefined" instead of crashing. fixes #1518Alex Lam S.L
2017-03-01v2.8.2Alex Lam S.L
2017-03-01invert `reduce_vars` tracking flag (#1519)...Modules like webpack and grunt-contrib-uglify still uses `ast.transform(compressor)` before `Compressor.compress(ast)` was introduced. Workaround this compatibility issue by deactivating `reduce_vars` in such case. Also fix use case with omitted `options` when calling `Compressor()`. fixes #1516Alex Lam S.L
