 * FUNCTION:    acpi_ex_do_debug_object

 *

 * PARAMETERS:  source_desc         - 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 acpi_gbl_enable_aml_debug_object is set, or

 * if ACPI_LV_DEBUG_OBJECT is set in the acpi_dbg_level. Thus, in the normal

 * operational case, stores to the debug object are ignored but can be easily

 * enabled if necessary.
