Re: [xmlvm-users] Starting java->objc and a few initial questions

[Arno P. <ar...@pu...>]

just to add my feedback: we are constantly doing things inside of XMLVM 
to make the cross-compiled code more efficient. Converting to a 
register-based machine is just the tip of the ice berg. Right now we try 
to get rid of the NSAutoreleasePool which causes much runtime overhead.
