You need a modern version of clang (one that supports ARC I suppose), so I think Xcode 4.2 is required. Compiling using -mmacosx-version-min=10.5 generates simple msg_send, and compiling for modern target generates call to _objc_autoreleasePoolPush/Pop. -- Jean-Daniel _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
