[webkit-dev] [PATCH] JSCore with GDB

[Filip Pizlo]

Can you combine this into a single patch and put it up for review on bugs.webkit.org?  Also please do add changelogs... It is our custom to have in the patches we put up for review. 

Which platforms is this tested on, btw?

Thanks for your work on this!
