Deprecated and Removed Compiler Options

This topic lists deprecated and removed compiler options and suggests replacement options, if any are available.

For more information on compiler options, see the detailed descriptions of the individual option descriptions in this section.

Deprecated Options

Occasionally, compiler options are marked as "deprecated." Deprecated options are still supported in the current release, but are planned to be unsupported in future releases.

Removed Options

Some compiler options are no longer supported and have been removed. If you use one of these options, the compiler issues a warning, ignores the option, and then proceeds with compilation.

The following two tables list options that are no longer supported.

Note that removed options are not limited to these lists.
