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

Maxthon,

Just a friendly reminder. :)

Please be very careful about what you disclose here, if you are under NDA.   I don't want a posting here to become any grounds for Apple to cause any issues for GNUstep.

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.
