Hello,

I would like to run some tests on v8 with and without JIT to compare performances. I know JIT will improve my average speed performance, but it would be nice for me to have some actual more detailed tests results as I want to work with mobile platforms.

I haven't found how to enable or disable JIT like it exists on Squirrelfish (cf. ENABLE_JIT in JavaScriptCore/wtf/Platform.h).

Does somebody knows how to do that with v8?

Thanks.

Alexandre

Writing PHP extension - Unable to load dynamic library

I'm writing a PHP extension similar to V8JS. The goal, like V8JS, is to embed the V8 engine into PHP so I can execute sandboxed JavaScript code in PHP. (The implementation is different.) The extension compiles fine, but when I attempt to run it I get: PHP Warning: PHP Startup: Unable to load… >>> More
