一些体系结构的栈生长方向

x86          down
SPARC        in a circle, very clever architecture, see below.
PPC          down, I think.
System z     in a linked list, I kid you not.
             (but still down, at least for zLinux).
ARM          selectable (thanks, Michael Burr).
Mostek6502   down (but only 256 bytes).
RCA1802A     any way you want, subject to SCRT implementation.
PDP11        down.
