...to the user. We will also be working on ways of specifying lists of targets to the LLVM/Clang build so that you won’t need to set COMPILER_RT_DEFAULT_TARGET_ARCH, and so that you can easily build for multiple targets while you build clang.

Hi. I'm trying to use Clang/LLVM as a cross-compiling toolchain. In previous version of LLVM with the old configure/Makefile building system, I'm able to build Clang/LLVM for target architecture with the host GCC firstly and then use the generated cross compiler to compile the compiler-rt project, and, consequently, I can get a cross compiler as well as the compiler-rt library. However,
