2; RUN: opt -module-summary %s -o %t.o
3; RUN: opt -module-summary %p/Inputs/thinlto_emit_linked_objects.ll -o %t2.o

5; Next do the ThinLink step, specifying thinlto-index-only so that the gold
6; plugin exits after generating individual indexes. The objects the linker
7; decided to include in the link should be emitted into the file specified
8; after 'thinlto-index-only='. In this version of the test, only %t.o will
9; be included in the link, and not %t2.o since it is within
10; a library (--start-lib/--end-lib pair) and not strongly referenced.
11; Note that the support for detecting this is in gold v1.12.
12; RUN: rm -f %t.o.thinlto.bc
13; RUN: rm -f %t2.o.thinlto.bc
14; RUN: rm -f %t.o.imports

26; the linker decided not to include in the link.
