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 $1 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.
