Compile Kernel 6.x with LLVM (Clang)

Hi, has anyone compiled this kernel with LLVM=1 (with clang) ?

I needed to test and adjust some Rust4Linux modules, and when I tried to compile with LLVM I got several minor errors.

Such as unused variables, cast conversions, in some drivers.

Any recommendation?

Another question, the Flag of the .config **Random memory address** is realy necessary to be enabled for VisionFive2?
