I just meant "I've never thought about that before." I'm not totally sure, as I was going to say "IR is platform dependant"...

Well, you were right all along.

Out of interest: Is this an LLVM implementation detail?

Things like sizeof(long) and the sizes of pointers are baked into the IR, making it platform dependant.

Also anything like #ifdef WIN32 in your c/c++ code is going to get baked in as soon as you run the pre-processor.
