VMS Debug (GNU Compiler Collection (GCC) Internals)

#### 19.23.3 Macros for VMS Debug Format ¶

Here are macros for VMS debug format.

Macro: VMS_DEBUGGING_INFO ¶

  Define this macro if GCC should produce debugging output for VMS in response to the `-g` option. The default behavior for VMS is to generate minimal debug info for a traceback in the absence of `-g` unless explicitly overridden with `-g0`. This behavior is controlled by `TARGET_OPTION_OPTIMIZATION` and `TARGET_OPTION_OVERRIDE`.
