So Walter's point would be that you could add |
| 9 |
|
| 10 |
mmx mmxext sse sse2 3dnow 3dnowext |
| 11 |
|
| 12 |
to your use flags, either globally in your make.conf file or for |
| 13 |
specific packages in package.use. Adding these flags will enable clode |
| 14 |
within the program being emerged specifically supporting those |
| 15 |
features. |
| 16 |
|
| 17 |
My point was that without adding these flags to the compile options |
| 18 |
(CXFLAGS) in make.conf I'm not clear that adding the flags in the USE |
| 19 |
section of make.conf does anything to generate actual sse or mmx code. |

I'd like to hear from some folks who really understand how gcc works |
| 22 |
about this. It's confused me for quite awhile. |
