I can fair use, can't I? Their NDA is built on top of copyright.

I don't want a posting here to become any grounds for Apple to cause any issues for GNUstep.GregoryOn Sat, Jun 15, 2013 at 5:57 AM, Maxthon Chan <address@hidden> wrote:
I am watching a video session from WWDC 2013 and Apple revealed their way of implementing tagged pointers: use the sole LSB, 1 for tagged pointer and 0 for normal ones. This is applied across all platforms, i386, amd64, armv7 and armv7s (compatible to armv7a in Coretx-A15 and partly compatible with AArch64 in 32-bit mode)
Okay technically I am still under NDA so this is pretty much what I can say.
