2017-12-01improve compression of `if` conditions (#2544)Alex Lam S.L
2017-11-29fix `inline` on nested substitutions (#2533)Alex Lam S.L
fixes #2531
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
2017-11-09fix multiple nested function substitutions (#2458)Alex Lam S.L
fixes #2449
2017-11-05inline single-use functions that are not constant expressions (#2434)Alex Lam S.L
fixes #2428
2017-10-22safer `properties` transform (#2391)Alex Lam S.L
`{ a: x, b: y }.a` => `[ x, y ][0]` - `x` cannot be function containing `this` `[ x, y, z ][1]` => `(x, z, y)` - only if `z` is side-effect-free
2017-10-22fix `unsafe` escape analysis in `reduce_vars` (#2387)Alex Lam S.L
2017-07-02improve `inline` efficiency (#2188)Alex Lam S.L
... by teaching `collapse_vars` some new tricks. fixes #2187
2017-06-27improve `unsafe_Func` (#2171)Alex Lam S.L
- minimise disturbance to `compute_char_frequency()` - remove extraneous quotation marks
2017-06-23synchronise `mangle.properties` for `minify()` & `test/compress` (#2151)Alex Lam S.L
2017-06-17make defensive copies when `inline` (#2116)Alex Lam S.L
fixes #2114
2017-06-16correctly determine scope of `AST_This` (#2109)Alex Lam S.L
fixes #2107
2017-06-15suppress `inline` of `this` (#2103)Alex Lam S.L
fixes #2101
2017-06-15compute `uses_arguments` correctly in `figure_out_scope()` (#2099)Alex Lam S.L
fixes #2097
2017-06-13fix variable accounting in `inline` (#2085)Alex Lam S.L
fixes #2084
2017-06-06implement function inlining (#2053)Alex Lam S.L
- empty body - single `AST_Return` - single `AST_SimpleStatement` - avoid `/*#__PURE__*/` Miscellaneous - enhance single-use function substitution fixes #281
2017-06-06workaround webkit parsing error (#2056)Alex Lam S.L
apply `webkit` to jetstream tests
2017-05-31introduce `unsafe_Func` (#2033)Alex Lam S.L
Separate flag for #203 functionality.
2017-05-27extend `node_version` range on applicable tests (#2015)Alex Lam S.L
2017-05-27fix `hoist_funs` on block-scoped `function` under "use strict" (#2013)Alex Lam S.L
Technically not part of ES5, but commonly used code exists in the wild.
2017-05-02improve literal return optimization (#1860)kzc
2017-04-24fix `unused` on for-in statements (#1843)Alex Lam S.L
Only need to avoid `var` within the initialisation block. fixes #1841
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.
2017-03-05fix a corner case in #1530 (#1552)Alex Lam S.L
2017-03-03process code with implicit return statement (#1522)Alex Lam S.L
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 #1293
2017-03-02optimize trivial IIFEs returning constants (#1530)kzc
2017-01-19Add preventive test involving non-ascii function identifiersAnthony Van de Gejuchte
