...h.overflow.i64 which should take three arguments, the two i64's being added and an i1, being the carry from before. This and a similar usbb might be the only things missing to make IR efficient for developing low level routines for a bignum library! Bill.

Hi all, After searching for a decent compiler backend for ages (google sometimes isn't helpful), I recently stumbled upon LLVM. Woot!! I work on bignum arithmetic (I'm a professional mathematician) and have recently decided to switch from developing GPL'd bignum code to BSD licensed code. (See http://www.mpir.org/ which I contributed to for a while - a fork of GMP). Please bear with

I think from the C compiler's point of view, it is going to want it to work for any size above an i64, i.e. all the way up to an i128 so that if the user of the C compiler does this computation with __uint128_t's then it will Do The Right Thing TM. Basically, you want unsigned long a, b, c, d; .... const __uint128_t u = (__uint128_t) a + b; const unsigned long v = u >> 64; const

Hi all, I am wondering if there is a way to get a value by name in the C interface for the LLVM Jit? There seems to be a way to name values consistently, but no way to retrieve those LLVMValueRef's by name. I see it is possible to get a struct by name and a type by name and a function by name, and a few other esoteric things, but not a general value. The reason I am wanting this is that I

That's what I am doing of course, It;s just odd that I can get a global by name but not a local. Bill.
