I believe graph-coloring is no longer used for state-of-the-art register allocators, such as the one in LLVM. Apparently, for ISA with a small number of registers, graph-coloring is not as relevant because spillover is more important. https://lists.llvm.org/pipermail/llvm-dev/2017-December/119915.html https://lists.llvm.org/pipermail/llvm-dev/2017-December/1199...
