Developer Options (The GNU D Compiler)

### 1.7 Developer Options ¶

This section describes command-line options that are primarily of interest to developers or language tooling.

`-fdump-d-original` ¶

  Output the internal front-end AST after the `semantic3` stage. This option is only useful for debugging the GNU D compiler itself.

`-v` ¶

  Dump information about the compiler language processing stages as the source program is being compiled. This includes listing all modules that are processed through the `parse`, `semantic`, `semantic2`, and `semantic3` stages; all `import` modules and their file paths; and all `function` bodies that are being compiled.
