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 options. For example, for more information on -ax (Linux* OS and OS X*) or /Qax (Windows* OS), or -x (Linux* OS and OS X*) or /Qx (Windows* OS), see the compiler option description.

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.
