[PATCH] D62434: [lld-link] diagnose undefined symbols before LTO when possible

[Bob Haarman via Phabricator via llvm-commits]

inglorion added a comment.

The basic idea here is:

reportRemainingUndefines did two things: it attempts to resolve undefined symbols, and it reports any that remain undefined.

This splits reportRemainingUndefines into two functions, one which reports symbols which we know are unresolvable (reportUnresolvable, which we run before LTO) and one which actually does the resolution (resolveRemainingUndefines, which we run after LTO).

Then there is a little bit of added code report undefined symbols in bitcode files.
