Compiling compiler-rt for baremetal CortexM on Ubuntu Linux
Hello, I want to build LLVM/Compiler-rt for baremetal targets like Cortex-M3. By adopting CMake options from http://llvm.1065342.n5.nabble.com/llvm-dev-Compiling-for-baremetal-ARMv4-on-Ubuntu-Linux-tp124226p124500.html, I can only build "libclang_rt.builtins-x86_64.a" in lib/linux, but what I want to build is "libclang_rt.builtins.arm.a". My CMake options are: cmake -G Ninja
