-; This testcase tests the following flow:
-; - File A defines a linkonce_odr version of @foo which has inlined into @bar.
-; - File B defines a weak_odr version of @foo (identical definition).
-; - Linkage rules state File B version of @foo wins.
-; - Debug info for the subprograms of @foo match exactly. Without
-; intervention, the same subprogram would show up in both compile units, and
-; it would get associated with the compile unit where it was linkonce.
-; - @bar has inlined debug info related to the linkonce_odr @foo.
-;
-; This checks a corner case for the fix for PR22792, where subprograms match
-; exactly. It's a companion for subprogram-linkonce-weak.ll.

-; The LW prefix means linkonce (this file) first, then weak (the other file).
