| ## This test shows that llvm-objdump can handle sections with the same address |
| ## when symbols in those sections are referenced. In the past, the section |
| ## picked was non-deterministic, resulting in different symbols being found for |
| ## the section. The test uses YAML for the input, as we need a fully linked ELF |
| ## to reproduce the original failure. |
| |
| ## Two empty sections, one with symbol in, one without. |
