Hello all, |
2 |
|
3 |
Without wanting to become flame bait at all.. I'd just like to know why |
4 |
-O3 is the default (commented) -O in make.conf, even for x86 stage |
5 |
tarballs (I don't really know about the stageballs on other |
6 |
architectures). Although the usefulness / harm of this flag has been |
7 |
discussed to death, on the vast majority of x86 /desktop/ machines I |
8 |
don't really think this flag is that suitable, and I know many agree. |
9 |
|
10 |
The reason I ask is because many people who didn't really change the |
11 |
default flags beyond setting -march have come on #gentoo or on the |
12 |
forums unsatisfied with performance of Gentoo, and there are also |
13 |
several packages that still won't compile with -O3. |
14 |
|
15 |
As a default for x86, wouldn't -O2 be more suitable? My personal |
16 |
viewpoint is that if you want to set -O3 on x86, go ahead. But if you |
17 |
do, you should know why you want to do it, and what affects it will |
18 |
have. Many beginners who haven't really got their heads around CFLAGS |
19 |
will possibly read somewhere that -O3 gives the most optimisation and be |
20 |
sold there and then. |

Thanks, |
