[PATCH] D38721: [ELF] - Teach LLD to report line numbers for data symbols.

[George Rimar via Phabricator via llvm-commits]

grimar created this revision.
Herald added a subscriber: emaste.

Currently LLD is unable to report line number when reporting duplicate
declaration of some variable.

That happens because for extracting line information we always use .debug_line section
content which describes mapping from machine instructions to source file locations,
what does not help for variables as does not describe them.

In this patch I am taking the approproate information about data symbol locations
from the .debug_info section.

It is PR34826.
