| ## Test 1. When a section is renamed, its relocation section should be renamed |
| ## similarly. |

| ## 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.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{{ }} |

| 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{{ }} |

| Type: SHT_PROGBITS |

| 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{{ }} |

| ## 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 |

| ## 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{{ }} |
