Ha! I pulled+rebased and this code disappeared...I thought I had rebased on the wrong branch or committed work to master accidentally. Patch to stable-only inbound.
Side note: for stable, can you look into using _Generic() instead of __builtin_choose_expression() with typeof, or some __builtin_types_compatible_p() magic?
Yes, yes, we use __builtin_choose_expression() elsewhere, but we've started using _Generic(), and it's really the more natural model - in addition to being the standard C one.
Of course, there may be some reason why _Generic() doesn't work, but it _is_ the natural fit for any "for type X, do Y" kind of thing.
No?
Man, c'mon, I just got the __builtin_choose_expression() working! It's not...too bad...ish. (Besides, I'd actually have to learn how to use _Generic...I've never quite gotten anything I've written trying to use it to actually compile).
Do we have access to _Generic in GCC 4.9?
