## foo and bar interpose symbols in another DSO, so both are exported,
## even if --dynamic-list specifies only foo.

# SYM-DAG: bar
# SYM-DAG: foo

## bar is not specified in --dynamic-list, so it is not preemptable when
## producing a DSO, and its PLT does not have an associated JUMP_SLOT.

# REL:      .rela.plt {
# REL-NEXT:   R_X86_64_JUMP_SLOT foo 0x0
# REL-NEXT: }
