Further down in that file, we state:

AMD GCN GPU target.
Instead of GNU Binutils, you will need to install LLVM 13.0.1, or later, [...]
LLVM 13.0.1 may still be fine for gfx1030
('[...]/amdgcn-amdhsa/gfx1030/libgcc' does get built; I've not further
tested), but it's not sufficient for gfx1100 anymore:
Testing with the system compilers here, llvm-mc-14.0.6 also fails while
llvm-mc-15.0.7 accepts it.
Which version of LLVM should we be recommending?
>= LLVM 15, I think. How about the following wording? It still mentions
LLVM 13.0.1 for those that really need it but with for the default
setup, it requires 15+.
OK.
