About The best CFLAGS for longson2f?

[Wu Zhangjin]

Hi, All

Archlinux is a lightweight GNU/Linux distribution, which is optimized
for x86 system.

Now, I plan to build it for loongson2f, here is my plan:

1. build a basic system from scratch via lfs.

gcc 4.4.2, binutils 2.20 with the patch from Lemote, .... no X this
time.

2. build abs, pacman, srcpac for loongson2f

abs the basic building system of archlinux, pacman is the package
management tool, srcpac will help to install a package from source
code(something like the emerge from gentoo).

3. build the core packages for loongson2f

use abs to pull the whole source code directories and build the core
packages(and perhaps I need to build a local mirror). perhaps we can use
srcpac to build them directly. I need to find a automatical tool too.

Herein, I must find a suitable version of Xorg to ensure it work on
loongson2f, and also, anybody tried the tinyX? does it work on
loongson2f? and I plan to use lxde + openbox.

4. build the other important packages

....

Now, It's time to do the first job, to get a higher performance? which
CLFAGS we need to use?

looking forward to your reply!

Regards,
Wu Zhangjin

Just found a such tool, named pacbuilder, is available in the AUR of
archlinux, we can install it via yaourt.

The following two is not needed in latest xorg-server.
evdev is enough

[Ruan Beihong]

Just refer to the manual page of gcc.
-march=loongson2f -O3 should work.
BTW, I'm away from the 2F system for a long time.
