3.4.1.2 Omit Debugging Directives Listing Option

The -ad form of this option omits debugging directives from the listing. This option is useful when processing compiler-generated assembly code containing debugging information, as the compiler-generated debugging directives will not clutter the listing. The following example shows a listing using both the d and h sub-options. Compared to using the h sub-option alone (see the next section), the listing is much cleaner.
