I think we can fix this easily by using __attribute_const_
on the print_mac() declaration. Let me play with that.
Actually it seems the 'pure' attribute is more important
here. Although it's not semantically a perfect match,
what we need to tell the compiler is basically that:
1) the return value depends upon the inputs
2) if the input is not used, it's safe to avoid the call
and 'pure' accomplishes that without any unwanted side-effects.
I think this will not result in any unwanted over-optimization.
Because if the inputs change in any way GCC has to emit the
call.
Any objections?
This seems fine to me, thanks Dave.
