[PATCH] D23488: ThinLTO: add early "dead-stripping" on the Index

[Peter Collingbourne via Phabricator via llvm-commits]

pcc added a comment.

This information will probably need to be encoded in the summary somehow once we're at the point where we no longer need to load the module during symbol resolution.

I think at this point we just need to collect a set of GC roots in add{Regular,Thin}LTO in the same way that we collect the set of used variables with collectUsedGlobalVariables.
