[PATCH] D65430: Add `--dependency-files` option, which is equivalent to compiler option -MD.

[Fangrui Song via Phabricator via llvm-commits]

MaskRay added a comment.

I have mentioned this several times. You can just process `-t` output like `{ echo -n 'a: '; clang a.o -o a -Wl,-t | sed 's/(.*//' | sort -u | sed '$!s/$/ \\/';} > a.d`

The problems are summarized previously and I don't see they are addressed. Given an existing simple way listing dependencies, I don't think we need more -M* like options.
