2015-10-07Add proper support for "use asm"; blocks. Disable -c optimization within ↵kzc
"use asm"; sections and preserve floating point literals in their original form. Non-asm.js sections are optimized as before. Asm.js sections can still be mangled and minified of whitespace. No special command line flags are required.

2015-08-25Don't change sequences that influence lexical binding in callsRichard van Velzen
Fixes #782
2015-08-10[Fix] --define replaces SymbolRefs in LHS of assignmentsChristopher Chedeau
See #208 for context
2015-07-29Advanced way to specify if a function call might have side effects. #400thorn0

2015-07-20Merge pull request #735 from kzc/masterMihai Bazon
optimizations for && and || where left side is constant expression

2015-05-18Fix compressing conditionalsMihai Bazon
Only transform foo() ? EXP(x) : EXP(y) into EXP(foo() ? x : y) if EXP has no side effects. Fix #710
2015-05-04Avoid spurious brackets when dropping unused varsMihai Bazon
Fix #702
2015-04-17Drop NaN -> 0/0 transformation.Mihai Bazon
Fix #687
2015-04-13Fix compression of conditionalsMihai Bazon
Don't move the condition on the right side of an assignment when the left side may have side effects. Fix #677
2015-03-23Fix compressing `![foo()];` as a statementMihai Bazon
need to check whether the literal has any side effects before replacing that with `false`.
2015-03-22[sequencesize] Actually even better:Mihai Bazon
do create the sequence even if the stat list is bigger than 2000 statements, but limit the sequence itself to 2000 expressions. Ref #414
2015-03-22Avoid sequencesize for more than 2000 statements.Mihai Bazon
It hardly saves any bytes for a sequence so long, and it risks blowing the stack with the recursive Seq functions. Ref #414
2015-03-22Add start/end nodes for NaN/Infinity transformationsMihai Bazon
2015-03-20Keep unused function arguments by defaultMihai Bazon
Discarding unused function arguments affects function.length, which can lead to some hard to debug issues. This optimization is now done only in "unsafe mode". Fix #121
2015-02-11Fix invalid removal of left side in && and || compressionRichard van Velzen
See #637. This does not produce the optimal result, but it does prevent the removal of non-side-effect-free code.
2015-01-31Drop all `console` statements properlyRichard van Velzen
Because the base reference can be an member expression as well, we have to dig a bit deeper to find the leftmost base reference. Fixes #451
2015-01-13Optimize conditionals where the consequent and alternative are both booleans ↵Tal Ater
and not equivalent
2015-01-12Replace the correct node when replacing in `void` sequencesRichard van Velzen
Close #611.
2015-01-11Merge pull request #482 from arty-name/inline-ng-injectMihai Bazon
added @ngInject support for inline functions
2015-01-07Fix make_node_from_constant for Regexp-sMihai Bazon
Close #588
2015-01-06aborts(AST_If) returns the `if` nodeMihai Bazon
Previously it returned the abort node from the alternative branch. This is not much use as it can be different from the one in the body branch (i.e. return vs. throw) and can trick us into issues like #591. Fix #591
2015-01-05Support keep_fnames in compressor, and --keep-fnames. #552Mihai Bazon
Passing `--keep-fnames` will enable it both for compressor/mangler, so that function names will not be dropped (when unused) nor mangled.
2015-01-04Fix #569Richard van Velzen
When no arguments are given to `new Function()`, it should be treated as a regular anonymous function (http://es5.github.io/#x15.3.2.1)
2014-12-31Fix #597Richard van Velzen
NaN and Infinity were replaced in the output generation, instead of during compression. This could lead to results where `1/0` was inserted without parens leading to invalid output. The nodes are replaced in the compression step now, and the output generation returns their regular names. This should not be a problem, since they're already only constructed from the original name.

2014-02-08Add option `keep_fargs`.Mihai Bazon
By default it's `false`. Pass `true` if you need to keep unused function arguments. Close #188.
