593677d2ff Add proper support for "use asm"; blocks. Disable -c optimization within "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. 2015-10-07 10:00:28 +02:00

5801fa39e9 [sequencesize] Actually even better: 
do create the sequence even if the stat list is bigger than 2000 statements,
but limit the sequence itself to 2000 expressions.

f0ab1b02e6 Avoid sequencesize for more than 2000 statements. 
It hardly saves any bytes for a sequence so long, and it risks blowing the
stack with the recursive Seq functions.

ecfd881ac6 Keep unused function arguments by default 
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".

992b6b9fcc Fix invalid removal of left side in && and || compression 
See #637. This does not produce the optimal result, but it does prevent the removal of non-side-effect-free code.

605362f89d Drop all console statements properly 
Because the base reference can be an member expression as well, we have to dig a bit deeper to find the leftmost base reference.

d2d716483a aborts(AST_If) returns the if node 
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.

e1f0747e4c Support keep_fnames in compressor, and --keep-fnames. #552 
Passing `--keep-fnames` will enable it both for compressor/mangler, so that
function names will not be dropped (when unused) nor mangled.

c75f5a1fd8 Fix #597 
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.
