Jak pravi `man gcc` ohledne -mfpmath=sse: |

|

"For i387 you need to use -march=cpu-type, -msse or -msse2 |
| 20 |
switches to enable SSE extensions and make this option effec- |
| 21 |
tive. For x86-64 compiler, these extensions are enabled by |
| 22 |
default." |
| 23 |
|
| 24 |
Z prvni vety to vypada, ze -march s vhodnym parametrem zaridi -msse, |
| 25 |
event. i -msse2. |
