Extended Description

Per description: intptr_t is an int on x86-32 Linux, but the clang stdint.h defines it as long.

I think we need target-specific code to deal with this.

This is really gross, is there any other option?

[efriedma-quic]

I can't think of any other good option... on Linux x86-32, intptr_t == int, and on Darwin, intptr_t == long (if I recall correctly). We can't really force a different definition onto the platform; among other things, it affects C++ name mangling.

[lattner]

I'd really rather keep stdint.h "target independent". Maybe PP.cpp should export an INTPTR_TYPE macro or something, which is int on linux and long on darwin?

[efriedma-quic]

That sounds like it'll work.

fixed, plz verify:
