[cfe-dev] Question on Objective-C Runtime(s)

[Gregory Gelfond]

Hi All,

This is my first posting to this list and I had some questions. I've
been attempting to read some of the archives and it appears that there
are a number of runtimes for Objective-C - the Apple runtime, GNU
runtime, and the one used by Etoile (developed by David Chisnall I
think). From what I read each has it's own possible benefits and
drawbacks, but reading this post by Chisnall on the Etoile blog:
http://etoileos.com/news/archive/2008/05/12/1719/ makes it appear that
his is a significant improvement over the GNU runtime.

Can anyone let me know what the various differences between the
runtime environments are. Also are there any plans to favor on over
another (or incorporate features from one to another)?

Thank you kindly for your time,
Gregory Gelfond
