Hhm, from the comment it seems that `idx` should always be contained in 32 bit, but the code apparently allows it to be bigger, provided that it's larger than `UINT64_MAX - INT32_MAX`. What's the actual intent?

The LLVM source casts it to an `unsigned int` without any further checking, so I think a warning if it's `> 0xffffffff` will suffice.
