7691bebea5 Rework has_directive
It's now available during tree walking, i.e. walker.has_directive("use
asm"), rather than as part of the scope.  It's thus no longer necessary
to call `figure_out_scope` before codegen.  Added special bits in the
code generator to overcome the fact that it doesn't inherit from
TreeWalker.

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.
