[PATCH] D70401: [RISCV] Complete RV32E/ilp32e implementation

Hi, I'm working on CH32V003 for rust and it uses RV32EC core.
I tried replacing my distros llvm and clang with a patched version of this like this:

  git clone https://aur.archlinux.org/llvm-git.git
  cd llvm-git
  mkdir src
  cd src
  git clone https://github.com/llvm/llvm-project.git
  cd llvm-project
  arc patch D70401
  cd ../..
  mv llvm-config.h src/
  makepkg -es
  sudo pacman -Rd --nodeps clang llvm
  makepkg -eid

but that bricked my xfce-wayland-manjaro DE (one screen black)
And in config.toml if I put

  [build]
  target = "riscv32i-unknown-none-elf"
  rustflags = [
  	"-C", "target-feature=+e,+c"
  ]

then build with cargo build
LLVM still complains it doesn't implement CodeGen for RV32E yet
What am I doing wrong?
Ended up reverting to repository llvm and clang, desktop now works again but CodeGen is obviously missing.
