## 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: llvm-objcopy --remove-section=foo --add-section=foo=%t4 %t %t5
# 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.
# RUN: echo -e -n "\x02\x01\x00\x01\x02" > %t6
# RUN: llvm-objcopy --add-section=bar=%t6 %t %t7
# RUN: llvm-objcopy --dump-section=bar=%t8 %t7
# RUN: diff %t8 %t6
# RUN: obj2yaml %t7 | FileCheck %s --check-prefix=RAW-DATA

## Check that raw data is well formated in the file as well.
# RAW-DATA:      Name: bar
# RAW-DATA-NEXT: Payload: '0201000102'
