    seems the kernel is not liking the parenthesis of the versioning of this clang version I cannot compile the kernel.
    Code:
    AMD clang version 12.0.0 (CLANG: AOCC_3.0.0-Build#78 2020_12_10) (based on LLVM Mirror.Version.12.0.0)
    include/config/auto.conf.cmd:1371: *** sintaxis no válida en condicional. Alto.

      I know this is of no help, but I just pulled the latest linux-tkg using aocc and it compiled successfully.

        Also Michael (Does that even work?).

        Could you possibly run some tests on AOCC for gaming. The last one you did (according to tagged articles) is 2017. It'd be nice to compare against GCC and LLVM with flto.

          No, it does not like the # character, not the parentheses. I fixed this in https://git.kernel.org/linus/c75173a...0bd012ce4cc2e7, cherry-pick that into whatever kernel you are compiling if not mainline.
