IA-32, IntelŪ EM64T, IntelŪ ItaniumŪ architecture
| Linux and Mac OS: | -mcpu=cpu |
| Windows: | None |
| cpu | Is the cpu for which the compiler should optimize. Possible values on IA-32 systems are: |
|
| pentium | Optimizes for IntelŪ PentiumŪ processors. | |
| pentiumpro | Optimizes for IntelŪ PentiumŪ Pro, Intel Pentium II, and Intel Pentium III processors. | |
| pentium4 | Optimizes for Intel Pentium 4 processors. | |
| itanium | Optimizes for IntelŪ ItaniumŪ processors. | |
| itanium2 | Optimizes for Intel Itanium 2 processors. | |
| itanium2-p9000 | Optimizes for Dual-Core Intel® Itanium® 2 Processor 9000 Sequence processors. | |
| pentium4 | On IA-32 systems, the compiler optimizes for Intel Pentium 4 processors. |
| itanium2 | On Itanium-based systems, the compiler optimizes for Intel Itanium 2 processors. |
This option tells the compiler to optimize for a specified cpu. On IntelŪ EM64T systems, only -mcpu=pentium4 is supported.
