Indicates to the compiler a feature set that it may target, including which instruction sets it may generate. Many of the following descriptions refer to Intel® Streaming SIMD Extensions (Intel® SSE) and Supplemental Streaming SIMD Extensions (SSSE). Possible values are:
This compiler option also supports many of the -m option settings available with gcc. For more information on gcc -m settings, see the gcc documentation. |
Default
Linux* systems: -msse2 |

Description
This option tells the compiler which features it may target, including which instruction sets it may generate.
Code generated with these options should execute on any compatible, non-Intel processor with support for the corresponding instruction set.
Options -x and -m are mutually exclusive. If both are specified, the compiler uses the last one specified and generates a warning.
Linux* systems: For compatibility with gcc, the compiler allows the following options but they have no effect. You will get a warning error, but the instructions associated with the name will not be generated. You should use the suggested replacement options.
