A.1 How Option Information Is Organized

To help you find information, compiler option descriptions are separated into the following subsections. If the option is one that is replaced by or identical to some other option, see the description of the other option for full details.

Table A–1 Option Subsections



Option Definition 

A short definition immediately follows each option. (There is no heading for this category.) 


If the option has one or more values, this section defines each value. 


If the option has a primary or secondary default value, it is stated here. 

The primary default is the option value in effect if the option is not specified. For example, if –compat is not specified, the default is –compat=5.

The secondary default is the option in effect if the option is specified, but no value is given. For example, if –compat is specified without a value, the default is -compat=4.


If the option has a macro expansion, it is shown in this section. 


If an example is needed to illustrate the option, it is given here. 


If the option interacts with other options, the relationship is discussed here. 


If there are cautions regarding use of the option, they are noted here, as are actions that might cause unexpected behavior.

This section contains references to further information in other options or documents. 

“Replace with” “Same as” 

If an option has become obsolete and has been replaced by another option, the replacement option is noted here. Options described this way may not be supported in future releases. 

If there are two options with the same general meaning and purpose, the preferred option is referenced here. For example, “Same as -xO” indicates that -xO is the preferred option.
