Alex Lam S.L	d1aa09c5c7	fix `reduce_vars` on conditionals (#1822 )	2017-04-18 01:44:23 +08:00
Alex Lam S.L	6d5f341999	fix `reduce_vars` on boolean binary expressions (#1819 ) Side effects of `&&` and `\|\|` have not mattered until #1814, which takes assignment expressions into account.	2017-04-17 17:24:29 +08:00
Alex Lam S.L	4ffb6fce76	compress duplicated variable definitions (#1817 ) These are surprisingly common, as people reuse the same variable name within loops or switch branches.	2017-04-17 17:11:29 +08:00
Alex Lam S.L	71a8d0d236	fix `reduce_vars` within try-block (#1818 ) Possible partial execution due to exceptions.	2017-04-17 14:03:29 +08:00

Alex Lam S.L	281e882d27	fix `reduce_vars` on catch variable (#1794 ) Improved catch handling in `figure_out_scope()` means special case treatment of IE8 is no longer valid in `reset_opt_flags()`. Also fixed recursive assignment in variable definition.	2017-04-07 12:32:56 +08:00
Alex Lam S.L	cc6aa3e5ac	fix incorrect context in variable substitution (#1791 ) `AST_Node.optimize()` is context-aware, so don't cache its results to be used elsewhere. Also fixed a few cases of AST corruption and beef up safety of `pure_getters`.	2017-04-07 03:42:17 +08:00

Alex Lam S.L	06cdb74279	improve `pure_getters` (#1786 ) - property access to `null` & `undefined` always has side effects - utilise `reduce_vars` to determine safe property access - may-be cases treated as side effects unless `unsafe`	2017-04-06 11:18:59 +08:00
Alex Lam S.L	ff289b90a9	implement delayed resolution for `reduce_vars` (#1788 ) Although it would be nice to enforce `AST_Node` cloning during transformation, that ship has sailed a long time ago. We now get the assigned value when resolving `AST_SymbolRef` instead of `reset_opt_flags()`, which has the added advantage of improved compressor efficiency. fixes #1787	2017-04-05 21:06:42 +08:00

Alex Lam S.L	a0c3836ba0	sort options in alphabetical order (#1743 ) They started off as functional groups I guess, but given the sheer number of options this is becoming too difficult to read.	2017-03-31 16:41:04 +08:00

Alex Lam S.L	eb48a035e7	fix corner case in `unused` (#1718 ) When fixing catch-related issue in #1715, it tries to optimise for duplicate definitions but did not take anonymous functions into account.

Alex Lam S.L	581630e0a7	fix typeof side effects (#1696 ) `statement_to_expression()` drops `typeof` even if it operates on undeclared variables. Since we now have `drop_side_effect_free()`, replace and remove this deprecated functionality.	2017-03-27 04:37:42 +08:00
Alex Lam S.L	f5952933a0	preserve side effects in switch expression (#1694 ) fixes #1690	2017-03-27 02:32:46 +08:00
Alex Lam S.L	f001e4cb9d	fix `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.	2017-03-27 01:58:21 +08:00
Alex Lam S.L	57ce5bd9e0	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.	2017-03-27 01:30:21 +08:00
Alex Lam S.L	861a79ac9f	fix `delete` related issues in `collapse_vars` and `reduce_vars` (#1689 )	2017-03-26 19:14:30 +08:00
Alex Lam S.L	e76fb354eb	fix `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 #1685	2017-03-26 18:08:44 +08:00
Alex Lam S.L	3276740779	fallthrough should not execute case expression (#1683 ) - de-duplicate trailing cases only, avoid all potential side-effects - enable switch statement fuzzing fixes #1680	2017-03-26 16:52:38 +08:00

Alex Lam S.L	b19aa58cff	fix `has_side_effects()` (#1675 ) `AST_Try` is an `AST_Block`, so besides try block we also need to inspect catch and finally blocks for possible side effects. Also extend this functionality to handle `AST_If` and `AST_LabeledStatement` while we are at it. fixes #1673	2017-03-25 23:03:26 +08:00

Alex Lam S.L	a30092e20f	fix invalid `AST_For.init` (#1657 ) Turns out the only place in `Compressor` which can generate invalid `AST_For.init` is within `drop_unused()`, so focus the fix-up efforts. supercedes #1652 fixes #1656	2017-03-25 03:18:36 +08:00

Alex Lam S.L	e918748d88	improve collapsible value detection (#1638 ) - #1634 bars variables with cross-scope references in between to collapse - but if assigned value is side-effect-free, no states can be modified, so it is safe to move	2017-03-24 02:55:32 +08:00

Alex Lam S.L	96f8befdd7	fix commit `88fb83a` (#1622 ) The following is wrong: `a == (b ? a : c)` => `b` Because: - `b` may not be boolean - `a` might have side effects - `a == a` is not always `true` (think `NaN`) - `a == c` is not always `false`	2017-03-19 11:59:42 +08:00
Alex Lam S.L	cd58635dcc	fix AST_Binary.lift_sequences() (#1621 ) Commit `eab99a1c` fails to account for side effects from compound assignments.	2017-03-19 03:04:22 +08:00
Alex Lam S.L	274331d0ea	transform String.charAt() to index access (#1620 ) Guarded by `unsafe` as `charAt()` can be overridden.	2017-03-19 02:17:15 +08:00
Alex Lam S.L	ac40301813	fix chained evaluation (#1610 ) `reduce_vars` enables substitution of variables but did not clone the value's `AST_Node`. This confuses `collapse_vars` and result in invalid AST and subsequent crash. fixes #1609	2017-03-17 00:26:48 +08:00

Alex Lam S.L	cf4bf4ceb1	fix stack issues with `AST_Node.evaluate()` (#1603 ) As patched in #1597, `make_node_from_constant()` makes inconsistent and sometimes incorrect calls to `optimize()` and `transform()`. Fix those issues properly by changing the semantics of `evaluate()` and `make_node_from_constant()`, with the side effect that `evaluate()` no longer eagerly converts constant to `AST_Node`.	2017-03-16 01:02:59 +08:00
Alex Lam S.L	8223b2e0db	fix `AST_Node.optimize()` (#1602 ) Liberal use of `Compressor.transform()` and `AST_Node.optimize()` presents an issue for look-up operations like `TreeWalker.in_boolean_context()` and `TreeWalker.parent()`. This is an incremental fix such that `AST_Node.optimize()` would now contain the correct stack information when called correctly.	2017-03-15 18:44:13 +08:00

Alex Lam S.L	cf45e2f79b	fixup for #1585 (#1589 ) As patched on `harmony`, `statement()` is the only user of `embed_tokens()` with a missing error branch. Updated test case and match up with `harmony` to facilitate future merging.	2017-03-10 10:49:41 +08:00

Alex Lam S.L	dedbeeff15	plan 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 #1568	2017-03-08 05:07:05 +08:00

Martijn Swaagman	98f330658f	Generate source map data from normalized files If using `inSourceMap` this fix will ensure the copying of `sourcesContent` is based on potentially normalized `sources` values (https://github.com/mozilla/source-map/blob/master/lib/source-map-consumer.js#L304-L309). For example `normalize` (https://github.com/mozilla/source-map/blob/master/lib/util.js#L80-L123) will rewrite `./dist/mySource.js` to `dist/mySource.js` in the target `_sources` of the `SourceMapConsumer`. As a result `orig_map.sourceContentFor(source, true);` would return `null` since the orginal `source` was no longer available in the consumer. By using the keys generating from the `SourceMapConsumer.constructor` consistency is ensured.	2016-11-29 20:42:56 +01:00

Anthony Van de Gejuchte	3a7d53f3cf	Move OctalEscapeSequence to read_escape_char This should simplify and improve implementation, make it easier to implement template strings, and keep master a bit more in sync with harmony. Previous implementation wasn't broken, though the loop gave me the impression it could read infinite numbers and annoyed me a bit.

Shrey Banga	e645ba84cf	Respect quote style in object literals The option added in `fbbaa42ee5` wasn't being respected inside object literals, so quoted property names would still be stripped out with this option. This is mostly a corner-case, but useful when the output is passed to something like the Closure compiler, where quoted property names can be used to prevent mangling.	2016-06-19 21:13:31 +02:00
