llvm/llvm/test/tools/llvm-dwarfdump/AMDGPU/amdgpu-relocs.yaml

## Tests llvm-dwarfdump handling of AMDGPU relocations. We provide a .debug_info
## section with multiple DW_AT_high_pc entries (that's one of the attributes for
## which relocations are resolved by llvm-dwarfdump) and we add a relocation for
## each of them. The first YAML document represents an amdgcn code object, and
## the second an r600 code object.
