## Test how llvm-readobj/llvm-readelf tools dump versioning sections.
## Check that SHT_GNU_versym dumper can see versions described in
## SHT_GNU_verdef and SHT_GNU_verneed sections.

# RUN: yaml2obj %s --docnum=1 -o %t1
# RUN: llvm-readobj -V %t1 | FileCheck %s --check-prefix=LLVM
# RUN: llvm-readelf -V %t1 | FileCheck %s --check-prefix=GNU
