## 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'

## 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.
