## Test --add-section. This test dumps and removes the section first and checks
## that adding it back doesn't change the result.
# RUN: yaml2obj %s -o %t
# RUN: llvm-objcopy --dump-section=producers=%t.sec --remove-section=producers %t %t2
# RUN: llvm-objcopy --add-section=producers=%t.sec %t2 %t3
# RUN: obj2yaml %t3 | FileCheck %s
## Check that the producers section has been added back unchanged.
# CHECK: Name: producers
# CHECK-NEXT: Tools:
# CHECK-NEXT: - Name: clang
# CHECK-NEXT: Version: 9.0.0
# Check that the section is replaced with new content in one invocation.
# RUN: echo "123" > %t4

# RUN: obj2yaml %t5 | FileCheck %s --check-prefix=REPLACE
# REPLACE: - Type: CUSTOM
# REPLACE: Name: foo
# REPLACE: Payload: 3132330A
## Check that raw data bytes can be imported and exported unchanged especially the ones containing empty bytes.
