I have not found where in Apple's doc that information is written. However,
here's what one of Apple's engineer has responded to me about that problem:


This is a courtesy email regarding Bug ID# 6910963.
Engineering has provided the following feedback regarding this issue:
Thank you for the additional information.
The asm code is wrong for 64-bit.  The software needs porting to work.  You
cannot use the "g" constraint for mov.  mov will take an "r" for example of
a constraint that will work.


Other than that, Apple's doc about porting code to 64-bits is here:
