[PATCH] D137933: [llvm-debuginfo-analyzer] 10 - Smart Pointers

[Carlos Alberto Enciso via Phabricator via llvm-commits]

CarlosAlbertoEnciso added a comment.

The main logical unit is the LVReader, which is the main access point from the user point of view. Its functions are:

- Load the binary file
- Parse the debug information
- Create the `logical view` which is a tree composed of `logical elements` (`LVScopes`, `LVSymbols`, `LVTypes` and `LVLines`, etc.). Depending on the command line options, additional information is added to the those logical elements.
- Print the `logical view`.
- Select `logical elements` using user criterias.
- Compare two `logical views'.

This is a very broad relationship between the reader and the logical elements.

  class LVReader {
    ...
    LVScopeRoot *Root = nullptr;
    ...
    createScopes() {
      Root = createObject<LVScopeRoot>();
    }
    ...
    doPrint()
    ...
  }
  
  class LVELFReader <- LVReader {
    ...
  }
  
  class LVCodeViewReader <- LVReader {
    ...
  }

`Root` represents the loaded binary file.

The different `Readers` are created by the `Reader Handler` based on the binary files format. It records each created reader.

  class LVReaderHandler {
    LVReaders TheReaders;
    ...
    createReaders();
    printReaders();
    compareReaders();
    ...
  }

  class LVScope <- LVObject {
    std::unique_ptr<LVTypes> Types;
    std::unique_ptr<LVSymbols> Symbols;
    std::unique_ptr<LVScopes> Scopes;
    std::unique_ptr<LVLines> Lines;
  }
  
  class LVScopeRoot <- LVScope {
     ...
  }

A `LVScope` can represent a `compile unit`, `function`, `lexical block`, etc.

The other logical elements:

  class LVLine <- LVObject {
    ...
  }
  
  class LVSymbol <- LVObject {
    ...
  }
  
  class LVType <- LVObject {
    ...
  }
