[LLVMdev] Returning i1 type ints from C code ? (original) (raw)

Hi Gordon,

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

Hi, I was wondering if there was any way to return an i1 type (or something that llvm would accept as one, internally) from a C function compiled with llvm-gcc.   My thought from searching around was that it might take rewriting (or at least writing a wrapper to %trunc the result) in assembly.   I’m fairly new to LLVM so I may have missed something important.  Any thoughts ? Thanks much, Gordon Keiser
