[LLVMdev] Returning i1 type ints from C code ?

Good to know.   I tried that last night with llvm-gcc just in case, but alas, it didn't help.   Good to know that Clang supports it for the future though.

Thanks everyone,

Hi Gordon,

Clang can do it if you include <stdbool.h> .  I found this out when writing a LibC wrapper library for LLVM Bitcode.
