ich habe auch Intel pentrium M procesor, ich habe mich nach diesen howto |

Pentium-M / Centrino (Intel) |

|

vendor_id : GenuineIntel |
| 14 |
cpu family : 6 |
| 15 |
model : 9 |

model name : Intel(R) Pentium(R) M processor XXXXMHz |

For gcc < 3.4.3: |
| 19 |
|
| 20 |
CHOST="i686-pc-linux-gnu" |
| 21 |
CFLAGS="-O2 -march=pentium3 -pipe -mfpmath=sse" |
| 22 |
CXXFLAGS="${CFLAGS}" |
| 23 |
|

Comment: I also have working system but no benchmark in speed difference |
| 25 |
to the above with: |
| 26 |
|
| 27 |
CHOST="i686-pc-linux-gnu" |
| 28 |
CFLAGS="-O2 -march=pentium4 -pipe -fomit-frame-pointer" |
| 29 |
CXXFLAGS="${CFLAGS}" |
| 30 |
|
| 31 |
For gcc >= 3.4.3: |
| 32 |
|
| 33 |
CHOST="i686-pc-linux-gnu" |
| 34 |
CFLAGS="-O3 -march=pentium-m -pipe -fomit-frame-pointer" |
| 35 |
CXXFLAGS="${CFLAGS}" |
| 36 |
|
| 37 |
Indeed it seems more a question of belief than of real speed if you use |
| 38 |
optimization level O2 or O3. O3 works well for me, but people may prefer |
| 39 |
to stick with O2. Options concerning SSE and such things sometimes may |
| 40 |
cause very long compile times until errors occur. |
