[PATCH] D109977: LLVM Driver Multicall tool

Thanks @mgorny I was able to get CMake to run. Although I didn't end up with the same error as you. I simply had warnings:

  CMake Warning (dev) at <redacted>/usr/local/lib/cmake/llvm/TableGen.cmake:103 (add_custom_command):
    Policy CMP0116 is not set: Ninja generators transform DEPFILEs from
    add_custom_command().  Run "cmake --help-policy CMP0116" for policy
    details.  Use the cmake_policy command to set the policy and suppress this
    warning.
  Call Stack (most recent call first):
    cmake/modules/AddClang.cmake:25 (tablegen)
    include/clang/AST/CMakeLists.txt:1 (clang_tablegen)
  This warning is for project developers.  Use -Wno-dev to suppress it.

When running just `cmake ../clang -G Ninja` did you delete CMakeCache.txt? If you didn't then perhaps something from the full command you gave stayed around and caused the error. I suspect then I will need the full command you have supplied above including gentoo_common_config.cmake. Likely I will not need gentoo_toolchain.cmake

Me too. For these tools to be installable as symlinks to the llvm driver, D127800 <https://reviews.llvm.org/D127800> will need to land, as well as a follow up after that patch. Maybe I could entice you to take a look :)
