Hi Richard/Anastasia,

I replied in the commit email, and here are some explains:

1. Without the space after comma the "//" will be aligned.
2. We want generic prototypes of the builtin functions, and we generate them in CodeGen. So there will be no use to perform conversion in sema for the function prototype.
3. We used generic prototypes and varadic function declration, the conversion in CodeGen use cast and won't change the original type for some arguments that maybe used elsewhere. (Also I do not understand very clear about how to convert in Sema)

Thanks
Xiuli

Here we need a different access qualifier then we have. I seems to complicated to generated a useless attribute here just for a name.
