[PATCH] D78032: [llvm-objdump] Default to the "apple-latest" mcpu when disassembling arm64 Mach-O binaries

[Lang Hames via Phabricator via llvm-commits]

lhames added a comment.

I would prefer to keep this change in the tool for now (as this patch does).

For disassembly purposes it makes sense to assume the newest CPU in case the object uses instructions from it. As a MachOObject file client on the other hand I would have expected getArchTriple to be conservative (i.e. "this object uses / requires the CPU specified"). I'm open to changing / reinterpreting getArchTriple's behavior, but I think that's a separate discussion from this patch and shouldn't block this going in.
