[PATCH] D76250: [llvm-objdump] Only reject -long-option in objdump mode

[Fangrui Song via Phabricator via llvm-commits]

MaskRay added a comment.

I was also of the opinion that "llvm-objdump" (argv[0]) and "objdump" (argv[0]) should reject single-dash `-long-option`.

However, @compnerd mentioned that on Mach-O platforms, `-long-option` may be used. Xcode uses the source code of llvm-objdump but it is not clear how they use the tool. They have patches and tests which are not upstreamed. If they provided a concrete tool name, I would like to allow `--long-option` when argv[0] matches that tool name (may be otool or something).

If we know how they use the tool, for example, if they always pass `--macho`, we can get rid of the alias `-m`.
