#23 Processor Targetting / Instruction Set Limiting

[irq3]

It'd be excellent if I could specify a target CPU (like
8086) and nasm would only recognize instructions for
that processor. Often one wants to make sure some
code is compatible with a lowest common denominator.
Given that simple instructions like "shr al, 3" are not
supported on older processors, it is easy to
write "incompatible" code.
So when you're done coding all of the important
features, put a target processor commandline option in
there for me ok? ;)

thanks,

There's the CPU directive currently available, but no
command-line equalent, I think...
