2018-05-03compress `AST_Sequence` within `AST_Call` (#3117)Alex Lam S.L
2018-02-28enhance `collapse_vars` (#2952)...- `a = b, b` => `a = b` - `a.b = c, c()` => `(a.b = c)()`Alex Lam S.L
2018-01-19enable `unsafe` for `test/ufuzz.js` (#2819)...- introduce `unsafe_undefined` - safer `.toString()` compression Miscellaneous - rename `unsafe_Function`Alex Lam S.L

2018-01-01enhance `join_vars` & `sequences` (#2697)...- nudge declarations without assignments - within `AST_BlockStatement` - across `AST_If`Alex Lam S.L
2017-12-14fold `cascade` functionality into `collapse_vars` (#2586)Alex Lam S.L
2017-12-01improve `AST_For.init` & `AST_Switch.expression` compression (#2546)Alex Lam S.L
2017-09-16handle LHS side-effects on `cascade` & `collapse_vars` (#2314)...fixes #2313Alex Lam S.L
2017-07-03improve parenthesis emission (#2196)...- eliminate `throw` usages - suppress extraneous parenthesis - `new function() {foo.bar()}.baz` - `for (function() { "foo" in bar; };;);`Alex Lam S.L
2017-06-07fix `cascade` on multi-branch evaluations (#2067)...Partially reverts #2059 as this has better coverage and performance. fixes #2062Alex Lam S.L
2017-05-12remove support for `const` (#1910)...As this is not part of ES5.Alex Lam S.L
2017-05-12fix invalid transform on `const` (#1919)...- preserve (re)assignment to `const` for runtime error - suppress `cascade` on `const`, as runtime behaviour is ill-definedAlex Lam S.L
2017-04-19extend `cascade` into `a.b` (#1829)...fixes #27Alex Lam S.L
2017-04-12convert `AST_Seq` from binary tree to array (#1460)...- rename `AST_Seq` to `AST_Sequence` - raise default sequences_limit from 200 to 800Alex Lam S.L
2017-04-08fix `delete` corner cases (#1799)...- assignment - boolean - conditional - sequenceAlex Lam S.L
2017-04-02fix corner cases in switch and undefined (#1762)...- fix side effects in switch condition for singular blocks - fix `undefined` confusion with local variable - gate `OPT(AST_Switch)` with `switches` fixes #1758 fixes #1759Alex Lam S.L
2017-03-27fix `cascade` on anonymous function reference (#1693)...Unlike normal variables and even function definitions, these cannot be reassigned, even though assignment expressions would "leak" the assigned value as normal.Alex Lam S.L
2017-03-26fix `cascade` on `delete` operator (#1687)...Conditions including strict mode would make `delete` return `true` or `false`, and are too complex to be evaluated by the compressor. Suppress assignment folding into said operator. fixes #1685Alex Lam S.L
2017-03-19make `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
2017-03-19fix AST_Binary.lift_sequences() (#1621)...Commit eab99a1c fails to account for side effects from compound assignments.Alex 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
2017-03-03process 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
2017-02-21clean up `negate_iife`...- remove extra tree scanning phase for `negate_iife` - `negate_iife` now only deals with the narrowest form, i.e. IIFE sitting directly under `AST_SimpleStatement` - `booleans`, `conditionals` etc. will now take care the rest via more accurate accounting - `a(); void b();` => `a(); b();` fixes #1288 closes #1451 alexlamsl
2017-02-21`-c sequences=N` suboptimal at N expression cutoff...N = 2: a; b; c; d; was: a, b; c; d; now: a, b; c, d; fixes #1455 closes #1457 alexlamsl
2014-09-28Referencing a global is assumed to have side effects....Close #550 Mihai Bazon
2013-11-06Better fix for #343...We can in fact lift sequences, but only if the operation is assignment and the left-hand side has no side effects nor property access -- that should guarantee that whatever we place before it cannot affect the sense of the assignment. Dropped contrived test case (too hard to support it now), added a more meaningful one. Mihai Bazon
2012-10-30don't move expressions containing the binary `in` operator into the `for` ini......(opera can't parse it) close #25 Mihai Bazon
2012-10-22more sequence optimizations (lift some sequences above binary/unary expressio...Mihai Bazon
2012-09-24minor tests fixMihai Bazon
2012-09-17one more test for sequencesMihai Bazon
2012-08-22wrote more of the compressor and added some testsMihai Bazon
