求 gcc 的编译优化参数

一时心血来潮 想编译 X 和 mozilla
但论坛的搜索功能实在是太... 1个小时仍然找不到有用的...

请那位指点一下 小生不胜感激

CPU是AMD Athlon 1700+ 的 256MB的内存 主板是 sis的

发行版 slackware 10 GCC 3.3.4


版主不要删  发在基础版没人理  只好转发到这了
相信这个问题在这里是 小菜一碟
:p

d00m3d

CFLAGS="-march=pentium3 -O3 -pipe -fomit-frame-pointer"
CXXFLAGS="-march=pentium3 -O3 -pipe -fomit-frame-pointer"

This is save, not too aggressive and suggested by gentoo gurus.

Fleta

CFLAGS="-O3 -march=athlon-xp -funroll-loops -fprefetch-loop-arrays -pipe"
This is the setting for Gentoo Athlon-xp stage3 tarball.

Fleta

发重了。

athlon_r

谢谢 两位啦...    就这一句吗？

d00m3d兄是看我的签名了吧...   那个是错的配置... 不过还是谢谢...

d00m3d

Oops!  I overlooked you were talking about an Athlon, not the P3 in your signature.  Fleta's CFLAGS is more applicable.

MACHINE

CFLAGS="-pipe -march=athlon-xp -mfpmath=sse -mmmx -msse -m3dnow -maccumulate-outgoing-args -minline-all-stringops -momit-leaf-frame-pointer -O3 -ffast-math -fforce-addr -fomit-frame-pointer -fprefetch-loop-arrays -ftracer -funroll-loops"

CXXFLAGS="-pipe -march=athlon-xp -mfpmath=sse -mmmx -msse -m3dnow -maccumulate-outgoing-args -minline-all-stringops -momit-leaf-frame-pointer -O3 -ffast-math -fforce-addr -fomit-frame-pointer -fprefetch-loop-arrays -ftracer -funroll-loops -fno-rtti"

## GCC3.4 to add: -funit-at-a-time -fpeel-loops -funswitch-loops

LDFLAGS="-Wl,-O3 -Wl,--enable-new-dtags -Wl,--sort-common -s"

athlon_r

我的slackwre  下没有/etc/make.conf 文件
我自己建立一个 是否有效?

d00m3d

I don't think slackware read make.conf, it is gentoo specific.

You may export the CFLAGS in your own profile.

athlon_r

也就是说 在我的主目录下 建立 .profile文件
内容如下
==================

export CFLAGS="-pipe -march=athlon-xp -mfpmath=sse -mmmx -msse -m3dnow -maccumulate-outgoing-args -minline-all-stringops -momit-leaf-frame-pointer -O3 -ffast-math -fforce-addr -fomit-frame-pointer -fprefetch-loop-arrays -ftracer -funroll-loops"

export CXXFLAGS="-pipe -march=athlon-xp -mfpmath=sse -mmmx -msse -m3dnow -maccumulate-outgoing-args -minline-all-stringops -momit-leaf-frame-pointer -O3 -ffast-math -fforce-addr -fomit-frame-pointer -fprefetch-loop-arrays -ftracer -funroll-loops -fno-rtti"

==========================

是这样吧...
