test/tools/llvm-readobj/ELF/needed-libs.test

## In this test we check the --needed-libs option.

# RUN: yaml2obj %s --docnum=1 -o %t1
# RUN: llvm-readobj --needed-libs %t1 2>&1 \
# RUN:   | FileCheck %s -DFILE=%t1 --implicit-check-not=warning: --strict-whitespace --check-prefix=NEEDED-LIBS
# RUN: llvm-readelf --needed-libs %t1 2>&1 \
# RUN:   | FileCheck %s -DFILE=%t1 --implicit-check-not=warning: --strict-whitespace --check-prefix=NEEDED-LIBS

## Check that library names are sorted when printed.
## Document that we also sort error entries.
