[Alexey Lapshin via Phabricator via llvm-commits]

avl added inline comments.


================
Comment at: llvm/include/llvm/Object/ObjCopy/ELF/ELFObjcopy.h:41
+/// Applies the transformations described by \p Config and \p ELFConfig to
+/// \p In(FileFormat::ELF or FileFormat::Unspecified) and writes
+/// the result into \p Out.

I'm guessing that's just because earlier logic will detect that the input buffer is an ELF file if no explicit input format is specified, and feed it through to here. If that's the case, we shouldn't be mentioning this case, since in both cases, we're working with an ELF file.
The idea of these descriptions is to match with values which are in: 

```
struct CommonConfig {
...
  FileFormat InputFormat = FileFormat::Unspecified;
...
};

enum class FileFormat {
  Unspecified,
  ELF,
  Binary,
  IHex,
};

```
It would probably be better to make FileFormat more descriptive by adding values: COFF, MachO, Wasm instead of Unspecified; RawELF instead of Binary... But I think this refactoring should be done separately. The idea of current doc comments is to show connection of CommonConfig.InputFormat and corresponding executeObjcopyOn* functions.
