It is generally not useful when building code, so I have emphasized that `clang -march=` does not support `all`. I think such a feature list does not exist in the disassembler.
There is some maintenance cost, but lacking some stuff when new target features emerge does not matter: people running llvm-objdump may notice and we can add new target features to "all".
