Sections:

## Test 1. When a section is renamed, its relocation section should be renamed
## similarly.
# CHECK: Name: .tst1.ren.foo{{ }}
# CHECK: Name: .rel.tst1.ren.foo{{ }}
# CHECK: Name: .rela.tst1.ren.bar{{ }}
# CHECK: Name: .tst1.ren.bar{{ }}
  - Name:  .tst1.foo
    Type:  SHT_PROGBITS
  - Name:  .rel.tst1.foo
    Type:  SHT_REL
    Info:  .tst1.foo
  - Name:  .rela.tst1.bar
    Type:  SHT_RELA
    Info:  .tst1.bar
  - Name:  .tst1.bar
    Type:  SHT_PROGBITS

## Test 2. A relocation section should be renamed together with its target
## section even if its name does not follow the typical pattern.
# CHECK: Name: .tst2.ren.foo{{ }}
# CHECK: Name: .rel.tst2.ren.foo{{ }}
  - Name:  .tst2.foo
    Type:  SHT_PROGBITS
  - Name:  .tst2.foo.rel
    Type:  SHT_REL
    Info:  .tst2.foo

## Test 3. A relocation section should not be renamed if an unrelated section
## with the same common name is renamed.
## Note that '.rel.tst3.foo' targets '.tst3.bar', not '.tst3.foo'
# CHECK: Name: .tst3.ren.foo{{ }}
# CHECK: Name: .tst3.bar{{ }}
# CHECK: Name: .rel.tst3.foo{{ }}
  - Name:  .tst3.foo
    Type:  SHT_PROGBITS
  - Name:  .tst3.bar
    Type:  SHT_PROGBITS
  - Name:  .rel.tst3.foo
    Type:  SHT_REL
    Info:  .tst3.bar

## Test 4. A relocation section can be renamed with an explicit --rename-section
## command. Explicit renaming overrides implicit one.
# CHECK: Name: .tst4.ren.foo{{ }}
# CHECK: Name: .tst4.ren.foo.rel{{ }}
  - Name:  .tst4.foo
    Type:  SHT_PROGBITS
  - Name:  .rel.tst4.foo
    Type:  SHT_REL
    Info:  .tst4.foo

## Test 5. Should not rename a relocation section if it or its target are not
## specified in --rename-section.
## Note that this diverges from GNU objcopy.
# CHECK: Name: .tst5.foo{{ }}
# CHECK: Name: .tst5.foo.rel{{ }}
  - Name:  .tst5.foo
    Type:  SHT_PROGBITS
  - Name:  .tst5.foo.rel
    Type:  SHT_REL
    Info:  .tst5.foo

## Test 6. A dynamic relocation section should not be renamed together with its
## target section.
# CHECK: Name: .tst6.rela.plt{{ }}
# CHECK: Name: .tst6.ren.got.plt{{ }}
  - Name:  .tst6.rela.plt
    Type:  SHT_RELA
    Flags: [ SHF_ALLOC ]
    Info:  .tst6.got.plt
  - Name:  .tst6.got.plt
    Type:  SHT_PROGBITS

## Test 7. A dynamic relocation section can be renamed with an explicit
## --rename-section command.
# CHECK: Name: .tst7.ren.rela.plt{{ }}
# CHECK: Name: .tst7.got.plt{{ }}
  - Name:  .tst7.rela.plt
    Type:  SHT_RELA
    Flags: [ SHF_ALLOC ]
    Info:  .tst7.got.plt
  - Name:  .tst7.got.plt
