[LLVMdev] Portable I/O

I'm attempting to use file I/O across platforms from LLVM assembly using the standard GNU C library: fprintf(), stdin/stdout, etc. Ideally I'd like to simply provide a single bitcode file that could be compiled on each platform, but because the internals of the I/O on each platform is different, this is not currently workable.
So my question is this: How do you suggest doing I/O in a portable way from LLVM assembly?
My current thoughts run along two lines:
1. Writing a non-portable wrapper around the I/O routines to present a common interface to the calling module.
2. Conditional assembly for each platform, but I don't see any facilities for this in LLVM assembly.
Are there any other ways to do this or any projects in the works that may provide a solution?
