Get codebase completely working with LLVM You can now build Cosmopolitan with Clang: make -j8 MODE=llvm o/llvm/examples/hello.com The assembler and linker code is now friendly to LLVM too. So it's not needed to configure Clang to use binutils under the hood. If you love LLVM then you can now use pure LLVM.
