[PATCH] D43571: [ELF] - Do not remove empty output sections that are explicitly assigned to phdr in script.

[George Rimar via Phabricator via llvm-commits]

grimar created this revision.
grimar added reviewers: ruiu, espindola.
Herald added subscribers: arichardson, emaste.

This continues direction shown in https://reviews.llvm.org/D43069.

I suggest to keep sections that are explicitly assigned to segment in script.
With that code can be simplified (as shown in diff).

Also with that it might be possible to get rid of `Live` flag of output section (if we want).
