@rentzsch I'll try to remember to check today and file a bug if it does

@Catfish_Man I love it but messaging sending is a serious conceptual barrier toward optimization

@rentzsch aye. I got [NSDate date] fixed to not hit the ar pool though :)

@Catfish_Man very interesting! I’m not sure how that’s possible unless you’re playing some sort of cacheing magic

@rentzsch grep for callerAcceptsFastAutorelease here: http://opensource.apple.com/source/objc4/objc4-532.2/runtime/NSObject.mm …

turns out +[NSMutableArray array] and +[NSMutableArray new] should be near-equivalent in speed http://rentzsch.tumblr.com/post/75082194868/arcs-fast-autorelease … thanks @Catfish_Man

@rentzsch @Catfish_Man That doesn’t explain the +[NSData date]/gettimeofday() special case, though.

@mjtsai @rentzsch the optimization only works if the callee tail-calls the autorelease. In that case it failed to generate a tail call.
