Short answer: not for now, but I wish I would! For cross-compiling for embedded, I tried riscv64-unknown-elf-gcc (which might be riscv32-unknown-elf-gcc on other systems). It is as good and bad as GCC can be. Bugs (or me using it wrong?) led me to try LLVM/Clang. Clang, the other elephant in the room also worked, slightly better, but it is also much known for its very large code base, taking ages to compile. After a while night compiling clang, all I could get is: [ 83%] Linking CXX executable ../../bin/llvm-lto ld: error: undefined symbol: llvm::PassBuilder::OptimizationLevel::O0 Therefore, if I do a full clean rebuild of everything, I need to wait another night to get the next error. The LLVM people might each have a $10000 computer/server or have robust patience. I have not looked much further for now (getting ARM devices to blink for now). If I encounter something saner, I will let you know here.
