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.
