      @Catfish_Man I think +array still hits the autorelease pool under ARC

      @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.

      @Catfish_Man @rentzsch There was something about calling gettimeofday() that messed up the normal tail call optimization?

      @mjtsai @rentzsch yeah. Compilers are complicated apparently

          @Catfish_Man @rentzsch Anything in particular that would cause the same problem with other POSIX API calls?

          @mjtsai @rentzsch I can’t really guess. It’d be nice to have a “#error-if-not-tailcall” type of thing

          @Catfish_Man @mjtsai @rentzsch Write a test that runs otool to disassemble and verifies those functions do not end with `ret` or `bx lr`.

          @Catfish_Man @mjtsai @rentzsch Another idea: rdar://15951129 ER: Analyzer check for code that defeats ARC's autoreleased-return optimization

          @gparker @Catfish_Man @mjtsai @rentzsch: I have MRC code that does this intentionally.

          @numist @gparker @Catfish_Man @mjtsai @rentzsch I have ARC code that (ab)uses block's retaining of self for what are likely similar reasons.

          @zadr @numist @gparker @Catfish_Man @mjtsai @rentzsch Whoops. Meant to reply to @gparker's tweet about extending object lifetimes.
