## Check that local private externs -- symbols without N_EXT but with N_PEXT set
## -- are translation-unit-scoped. These symbols may be generated by `ld -r`,
## which emits an object file. Since LLD does not yet support `-r`, we use
## yaml2obj to construct the input.
# RUN: rm -rf %t; mkdir %t
# RUN: yaml2obj %s > %t/foo.o
## No duplicate symbol conflict since _foo is not extern
# RUN: %lld -dylib %t/foo.o %t/foo.o -o %t/foo
# RUN: llvm-nm -m %t/foo | FileCheck %s
## Note that the symbols in the output are no longer marked as "was a private
## external".
# CHECK: (absolute) non-external _bar
# CHECK: (absolute) non-external _bar
# CHECK: (__DATA,__data) non-external _foo
# CHECK: (__DATA,__data) non-external _foo
