I am now using core2 as I was having some really odd problems after |
| 41 |
mixing flags after multiple hardware changes along with native. Core2 |
| 42 |
is recommended for this processor, and I cant see the two flags changed |
| 43 |
via native making a difference, but the previous processors is no longer |
| 44 |
available to check. |
| 45 |
|
| 46 |
Perhaps someone could do the above and send me the result (the full "gcc |
| 47 |
-Q --help=target -march=native", using gcc-4.5) for an intel E4600? |
| 48 |
(the list probably wont be interested!) |
