Hi all, |

In make.conf we specify the optimization CXXFLAGS as follows: |
4 |
|
5 |
# For Pentium and k6/2 machines |
6 |
# ----------------------------- |
7 |
|
8 |
#CHOST="i586-pc-linux-gnu" |
9 |
#CFLAGS="-mpentium -march=pentium -O3 -pipe" |
10 |
#CXXFLAGS="-mpentium -march=pentium -O3 -pipe" |
11 |
|
12 |
Why don't we use -march=k6 -mcpu=k6? Wouldn't that allow use of mmx and |
13 |
3dnow, which a generic pentium doesn't have? |
14 |
|
15 |
|
16 |
# For PII PIII and Athlon machines |
17 |
# -------------------------------- |
18 |
|
19 |
#CHOST="i686-pc-linux-gnu" |
20 |
#CFLAGS="-mpentiumpro -march=pentiumpro -O3 -pipe" |
21 |
#CXXFLAGS="-mpentiumpro -march=pentiumpro -O3 -pipe" |
22 |

The same here: I believe (though I'm not sure as I don't have an Athlon) that |
24 |
the flags -mcpu=athlon -march=athlon might be of use. |
