Yes, if those 2 CPUs Kyle mentioned are Itanium processors - I doubt. I guess |
| 12 |
these are EM64T processors in which case the correct setting is somewhat |
| 13 |
misleading AMD64 . |
| 14 |
|
| 15 |
In case of EM64T, the system setting can be built upon this setting |
| 16 |
(in /etc/make.conf): |
| 17 |
|
| 18 |
CHOST="x86_64-pc-linux-gnu" |
| 19 |
CFLAGS="-march=nocona -O2 -pipe" |
| 20 |
CXXFLAGS="${CFLAGS}" |
| 21 |
|
| 22 |
The NOCONA setting is crucial, as Intel is slightly different from AMD. |
| 23 |
|
| 24 |
Also, look at your /proc/cpuinfo , flags section. Than set appropriate USE |
| 25 |
flags according to this table: |
| 26 |
|
| 27 |
CPU flag | set this |
| 28 |
present | USE flag |
| 29 |
-----------+--------- |
| 30 |
mmx | mmx |
| 31 |
sse | sse |
| 32 |
sse2 | sse2 |
| 33 |
pni | sse3 * |
| 34 |
mmxext | mmxext |
| 35 |
3dnowext **| 3dnowext |
| 36 |
3dnow **| 3dnow |
| 37 |
|
| 38 |
* No ebuild seems to use sse3 flag (yet) |
| 39 |
** Well, 3dnow is for AMD/AMD64, put here just for reference |
