According to GCC : |
| 2 |
CPUs based on AMD Family 10h cores with x86-64 instruction set support. |
| 3 |
(This supersets MMX, SSE, SSE2, SSE3, SSE4A, 3DNow!, enhanced 3DNow!, |
| 4 |
ABM and 64-bit instruction set extensions.) |
| 5 |

Best way to get that info : |
| 8 |
( simplest way ) cat /proc/cpuinfo |
| 9 |
( long form ) gcc -c -Q -march=native --help=target |
| 10 |
( short form ) gcc -### -march=native /usr/include/stdlib.h |
| 11 |
|
| 12 |
partial output of cat /proc/cpuinfo : |

| 41 |
-mmmx means USE FLAG "mmx" |
| 42 |
-msse == sse |
| 43 |
-msse2 == sse2 |
| 44 |
... etc. |
