Good point: |
| 22 |
|
| 23 |
-mcpu is deprecated, according to the examples file as of gcc 3.4, SO: |
| 24 |
|
| 25 |
CFLAGS="-Os -march=i586 -pipe -fomit-frame-pointer" |
| 26 |
CHOST="i586-pc-linux-gnu" |
| 27 |
|
| 28 |
changed to: |
| 29 |
CFLAGS="-Os -mtune=i586 -pipe -fomit-frame-pointer" |
| 30 |
or |
| 31 |
CFLAGS="-Os -march=i586 -mtune=i586 -pipe -fomit-frame-pointer" |
| 32 |
|
| 33 |
<????? Remember I want one set of binaries for both k6 and old pentiums> |

You're right, make it -mtune ;-). On the other hand, and according to |
| 43 |
Gentoo GCC optimization guide[1], both -mtune and -mcpu only take effect |
| 44 |
if there is no -march available, so I guess the later takes preference |
| 45 |
over the former. I'd use the first option of CFLAGS, hence. |
