maybe.. but imho we must use all advangates of having source codes and one of them is to make highly optimized builds..

also, gcc accepts -mtune= -mcpu= -march= with "iwmmxt" parameter (all gives same internal results)
so you can easily turn on Wireless MMX optimizations by specifiing these parameters in tune-blabla.conf

Yes, you are right. For example in h3900.conf (I'm not Zaurus owner, I use Linux on Ipaq H3970):

# not using tune-xscale so as to retain backwards compatibility
include conf/machine/tune-strongarm.conf

so here I changed to tune-xscale.conf

I haven't performed any comparisons yet. I simply was very surprised when saw that optimizations are specially disabled and re-enabled them. I'll look into more details about new optimization flags introduced in new gcc versions.

Depends who we is; we do use it in OpenEmbedded iirc.

but XScale optimizations are disabled by default in OE!

I have feed with Opie build with optimizations inside OE. More info at [a href=\"http://mifki.ru/el-apps]http://mifki.ru/el-apps[/url]
