SunPro cc and gcc have an option that will generate code optimized for
the v8 sparc processor. The gcc option is -mv8, the cc option is
something like -xcg92.
How can a process tell which type of processor it is running on.
It is one thing to say look at the label, is it sparc 2, or ipc, or
sparc 10 or sparc 20?
But if a process is going to make some assumptions, what can it test?
