...++ multithreading stuff, Java, etc) can have their synch needs met by LLVM. While doing both of these, we want the model to be something that is efficiently implementable on most architectures. Not every operation has to be equally efficient though: taking a spinlock to atomically update a i1234 variable is probably ok. :) Note that while LLVM doesn't have it's own -lllvm, it does use GCC's libgcc. libcc provides lib functions for things like "64-bit unsigned rem" for targets that don't support it. In 4.2, it also provides various synch support features. I...
