[cfe-commits] [PATCH] Utilize the indents in -ast-dump to draw structural information

[Richard Trieu]

  Use '`' instead of '\' when printing the tree structure.  Example output:

  (TranslationUnitDecl 0x6864660 <<invalid sloc>>
  |-(TypedefDecl 0x6864ba0 <<invalid sloc>> __int128_t '__int128')
  |-(TypedefDecl 0x6864c00 <<invalid sloc>> __uint128_t 'unsigned __int128')
  |-(TypedefDecl 0x6864fc0 <<invalid sloc>> __builtin_va_list '__va_list_tag [1]')
  `-(FunctionDecl 0x68651c0 <simple2.cc:1:1, line:5:1> main 'int (int, char **)'
    |-(ParmVarDecl 0x6865020 <line:1:10, col:14> argc 'int')
    |-(ParmVarDecl 0x68650f0 <col:20, col:27> argv 'char **')
    `-(CompoundStmt 0x68918c0 <col:33, line:5:1>
      |-(DeclStmt 0x68652f8 <line:2:3, col:12>
      | `-(VarDecl 0x6865280 <col:3, col:11> x 'int'
      |   `-(IntegerLiteral 0x68652d8 <col:11> 'int' 5)))
      |-(DeclStmt 0x68917c0 <line:3:3, col:12>
      | `-(VarDecl 0x6865320 <col:3, col:11> y 'int'
      |   `-(IntegerLiteral 0x68917a0 <col:11> 'int' 2)))
      `-(ReturnStmt 0x68918a0 <line:4:3, col:16>
        `-(ParenExpr 0x6891880 <col:10, col:16> 'int'
          `-(BinaryOperator 0x6891858 <col:11, col:15> 'int' '*'
            |-(ImplicitCastExpr 0x6891828 <col:11> 'int' <LValueToRValue>
            | `-(DeclRefExpr 0x68917d8 <col:11> 'int' lvalue Var 0x6865280 'x' 'int'))
            `-(ImplicitCastExpr 0x6891840 <col:15> 'int' <LValueToRValue>
              `-(DeclRefExpr 0x6891800 <col:15> 'int' lvalue Var 0x6865320 'y' 'int'))))))))
