Writing fast, processor-independent code using C++ and LLVM bitcode

Writing fast, processor-independent code using C++ and LLVM bitcode Using inline assembly along with C/C++ code has long been the best choice for developers writing optimized code. However the approach had its shortcomings: - the need to write assembly for each architecture - the use of inline assembly hinders certain compiler optimizations (such as register allocation) But thanks to LLVM it is no
