These terms refer to all supported Microsoft* Windows* operating systems.

These terms refer to all supported Linux* operating systems.

These terms refer to Intel®-based systems running the Mac OS* X operating system.

An asterisk at the end of a word or name indicates it is a third-party product trademark.

This term refers to Windows* OS options, Linux* OS options, or MAC OS* X options that can be used on the compiler command line.

A slash before an option name indicates the option is available on Windows OS. A dash before an option name indicates the option is available on Linux OS* and Mac OS* X systems. For example:
Windows option: /fast
Linux and Mac OS X option: -fast
Note: If an option is available on Windows* OS, Linux* OS, and Mac OS* X systems, no slash or dash appears in the general description of the option. The slash and dash will only appear where the option syntax is described.

Indicates that an option requires a argument (parameter). For example, you must specify an argument for the following options:
Windows OS option: /Qdiag-error-limit:n
Linux OS and Mac OS X option: -diag-error-limit n

Indicates that an option requires one of the keyword values.

Indicates that the option can be used alone or with an optional keyword.

Indicates that the option can be used alone or with an optional value; for example, in /Qfnalign[:n] and -falign-functions[=n], the n can be omitted or a valid value can be specified for n.

Indicates that a trailing hyphen disables the option; for example, /Qglobal_hoist- disables the Windows OS option /Qglobal_hoist.

Indicates that "no" or "no-" preceding an option disables the option. For example:
In the Windows OS option /[no]traceback, /traceback enables the option, while /notraceback disables it.
In the Linux OS and Mac OS X option -[no-]global_hoist, -global_hoist enables the option, while -no-global_hoist disables it.
In some options, the "no" appears later in the option name; for example, -fno-alias disables the -falias option.
