[PATCH] D54747: Discard debuginfo for object files empty after GC

[Robert O'Callahan via Phabricator via llvm-commits]

rocallahan added a comment.

I am also pleased to report that for my real project <https://robert.ocallahan.org/2018/05/update-pernosco.html>, switching from `ld.bfd` to `lld` + this patch reduces the total size of our `dist` built binaries from 2.9GB to 2.0GB.

I'm not sure why it's become more effective, but several variables have changed, including some significant restructuring of the build artifacts for our project. Still, this seems like a pretty good result. (Perhaps even suspiciously good! But I can't find any missing debuginfo with cursory checks.)
