Description Mike West 2013-03-06 14:17:29 PST
When generating code for constants in IDL files, we're currently pushing the values through "static_cast<signed int>" in order to ensure that values like "0xFFFFFFFF" are properly handled as "-1". There's no reason to do this work in C when Perl is perfectly capable of manipulating text.

The FIXME at http://trac.webkit.org/browser/trunk/Source/WebCore/bindings/scripts/CodeGeneratorV8.pm?rev=144976#L2933 has been around since 2009. Now's as good a time as any to take care of it.

Starting to dabble in bindings. Jochen, Dan, mind taking a look?

It broke the bindings generation tests. Could you fix it?
