llvm/test/tools/llvm-nm/elf-extern-only.test

## Test that the --extern-only switch only shows external ELF symbols.

# RUN: yaml2obj %s -o %t.o
# RUN: llvm-nm %t.o --extern-only --no-sort | FileCheck %s
# RUN: llvm-nm %t.o -g --no-sort | FileCheck %s

## Using --no-sort ensures that the symbols appear in the symbol table order
## allowing our CHECK-NOTs to work as expected.
# CHECK-NOT: local
# CHECK: D global_data_symbol
# CHECK-NEXT: T global_function_symbol
# CHECK-NEXT: U undefined
# CHECK-NEXT: W weak_symbol
# CHECK-NOT: local
