[U-Boot] Low priority request for info about alternative to #ifdef

[U-Boot] Low priority request for info about alternative to #ifdef

[James Chargin]

Hi

I've seen periodic discussion on the U-Boot mailing list of alternatives 
to #ifdef. I need a bit more information about one specific alternative, 
but in my searches of the source for 2017.03, I can't find examples that 
might help me. Also, my memory of this is a dim so I'm not sure I'm 
looking for the right thing.

Is there something that is similar to "#ifdef CONFIG_*" but looks more 
like "if_defined(CONFIG_*)" and relies on compile/link time elimination 
of unused code?

Thanks for your time.

Jim

Did I make a mistake including "Low priority" in the subject?

If anyone remembers this discussion, I'd appreciate a pointer.

Thanks,
Jim
