; First generate bitcode with a module summary index for each file
; RUN: opt -module-summary %s -o %t.o
; RUN: opt -module-summary %p/Inputs/thinlto_emit_linked_objects.ll -o %t2.o

; Next do the ThinLink step, specifying thinlto-index-only so that the gold
; plugin exits after generating individual indexes. The objects the linker
; decided to include in the link should be emitted into the file specified
; after 'thinlto-index-only='. Note that in this test both files should
; be included in the link, but in a case where there was an object in
; a library that had no strongly referenced symbols, that file would not
; be included in the link and listed in the emitted file. However, this
; requires gold version 1.12.
