## Build an object with a trivial main function
# RUN: llvm-mc -filetype=obj -triple=x86_64 %t/main.s -o %t1.o

## Build %t.a which defines a global 'foo'
# RUN: llvm-mc -filetype=obj -triple=x86_64 %t/archive.s -o %t2.o
# RUN: rm -f %t2.a
# RUN: llvm-ar rc %t2.a %t2.o

# RUN: llvm-mc -filetype=obj -triple=x86_64 %t/shlib.s -o %t3.o
# RUN: ld.lld %t3.o -o %t3.so -shared

## Test that 'foo' from %t2.a is fetched to define 'foo' needed by %t3.so.
## Test both cases where the archive is before or after the shared library in
## link order.
