08623aa6a7 Fix output for "use asm" code from SpiderMonkey AST

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.

18d37ac761 Fix parsing invalid input 
i.e. `x = 1.xe` — because parseFloat("1.xe") returns 1, this parsed as
`x = 1`.

63d35f8f6d Prevent ReDoS by not using a regexp to verify floating point numbers 
`parseFloat` will return `NaN` for invalid numbers anyway, which is the check used to throw the parse error.

4d2f7d83af Fix handling of "use asm" when no command line flags are passed to uglifyjs. SCOPE_IS_NEEDED is unconditionally true now. Refactored floating point literal parsing to be more in keeping with the AST class design. 2015-10-07 13:10:53 -04:00

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

ae07714927 Add filename to the JS_Parse_Error exception. 
It would be nice to have access to the filename of the file that includes the code that causes a JavaScript error. This is especially handy if uglifying multiple files at once.

Only a small change is needed for this to happen as it's already available in the function that throws the error.

fbbaa42ee5 Add option to preserve/enforce string quote style 
`-q 0` (default) use single or double quotes such as to minimize the number of
 bytes (prefers double quotes when both will do); this is the previous
 behavior.

`-q 1` -- always use single quotes

`-q 2` -- always use double quotes

`-q 3` or just `-q` -- always use the original quotes.

Related codegen option: `quote_style`.

Close #495
Close #460

Some `yargs` guru please tell me why `uglifyjs --help` doesn't display the
help string for `-q` / `--quotes`, and why it doesn't output the expected
argument types anymore, like good old `optimist` did.

c5ed2292bf Fix parsing setters/getters (allow keywords for name). 
The "key" property was always "set" or "get", which didn't make much sense.
Now it'll be the actual name of the setter/getter (AST_Node), and the
AST_Accessor object itself, which represents the function, won't store any
name.

bb0a762d12 Only allow identifier start characters at the beginning of identifiers. 
Without this fix, the following source:

   x = {"\u200c": 42};

would incorrectly be converted into a quoteless key. But while \u200c is allowed
to be in identifiers, it cannot be at the beginning, as per ES5.

(For example, the SockJS client library doesn't work under uglify starting with
d9ad3c7c.)

85b527ba3d Disallow continue referring to a non-IterationStatement. Fix #287 
Simplifies handling of labels (their definition/references can be easily
figured out at parse time, no need to do it in `figure_out_scope`).
