* PARAMETERS: SourceDesc - Object to be output to "Debug Object"
* Level - Indentation level (used for packages)
* Index - Current package element, zero if not pkg
*
* RETURN: None
*
* DESCRIPTION: Handles stores to the AML Debug Object. For example:
* Store(INT1, Debug)
*
* This function is not compiled if ACPI_NO_ERROR_MESSAGES is set.
*
* This function is only enabled if AcpiGbl_EnableAmlDebugObject is set, or
* if ACPI_LV_DEBUG_OBJECT is set in the AcpiDbgLevel. Thus, in the normal
* operational case, stores to the debug object are ignored but can be easily
* enabled if necessary.
