18 | The SIMD extension for x86 (AMD) (*if detected*). |
| 19 | Version number depends on the most recent detected extension. | |

47 | NOTE: This predef includes every other x86 SIMD extensions and also has other |
| 48 | more specific extensions (FMA4, XOP, SSE4a). You should use this predef | |
| 49 | instead of `BOOST_HW_SIMD_X86` to test if those specific extensions have | |
| 50 | been detected. | |
