Are there existing "generic" implementations for these functions under the same license as LLVM? By generic I mean C or IR that doesn't use any particular HW intrinsics. I read up on divides in Knuth's Seminumerical book, but decided to use base-2 long division on the first go-around for simplicity. I know it's not very efficient and I'm looking for shortcuts to

Hi Daniel, We're working on a complete ground-up implementation of the API vended by libgcc, including these routines, under the LLVM

Well, the answer is pretty obvious then. These calls are not generated by JIT. They are already in your bitcode - they are generated by llvm-gcc. The purpose of these calls were alreade explained by Eli. You should either
