IA-32 architecture, IntelŪ 64 architecture
| Linux and Mac OS X: | -tune keyword |
| Windows: | /tune:keyword |
| keyword | Specifies the processor type. Possible values are: | |
| pn1 | Optimizes for the IntelŪ PentiumŪ processor. | |
| pn2 | Optimizes for the IntelŪ PentiumŪ Pro, IntelŪ PentiumŪ II, and IntelŪ PentiumŪ III processors. | |
| pn3 | Optimizes for the IntelŪ PentiumŪ Pro, IntelŪ PentiumŪ II, and IntelŪ PentiumŪ III processors. This is the same as specifying pn2. | |
| pn4 | Optimizes for the IntelŪ PentiumŪ 4 processor. | |
| pn4 | The compiler optimizes for the IntelŪ PentiumŪ 4 processor. |
This option determines the version of the architecture for which the compiler generates instructions.
On systems using IntelŪ 64 architecture, only keyword pn4 is valid.
