questions about 8.0-RELEASE

[Horst Günther Burkhardt III]

Ok.

So, I heard it on the 'tubes that 8.0 is in BETA atm, and will rock
pretty damned hard.

But, I have a few questions, being a PowerPC user, and also having some
disappointment with the state of things in 7.2 especially on this
platform.

First, has libm finally had the log2 functions defined in the C99 spec
added? (this is an issue dating back to 2005, standards/83845 )

Second, I'm aware that altivec support is implemented in -CURRENT, as of
some months ago, will this be stable enough for release?

Third (more a support question), what's a good and quick way to clean
out every port? I'll need to recompile everything (damn tier 2 ;))

Fourth, how is the new shared versioning meant to work?

Thanks in advance,

-- Horst.

Hello,

For the ports part:
pkg_delete -fa
rm -rf /usr/ports/*/*/work

That'll result in a clean system, without any ports, and a wiping
workdirs. If you also want to remove the currently specified OPTIONS,
than also wipe /var/db/ports/ .

man pkg_delete; and man ports will help you understand what are these
command doing.

I've been compiling everything with altivec for the past few months,
with no problems, and I abuse the hell out of my system, so I can
safely say that it's stable enough for release.  Base won't have it
enabled, but you can enable it for ports in make.conf.

As far as I know, no. Many of the complex functions (e.g. cexp) aren't
implemented either, which can be a huge pain.

There was Altivec in 7.2-RELEASE as well, and it is quite stable. Ports
that know about it will use it by themselves, or you can define
something like CPUTYPE=7450 in make.conf to have the compiler try to
autovectorize things.

8.0 has a bunch of other new PowerPC features like audio, SMP, G5
support, ATA DMA, ADB keyboard and mouse support, some basic power
management, including cpufreq, etc. Hopefully it will be a better
experience than 7.2 -- the big architectural differences between 8.0
PowerPC and 7.0 PowerPC have made it difficult to MFC things for some time.

Hi
Just in reference to this..... or perhaps entirely OT ....

Will the 8.0 CD's/DVD's release also have the "rescue-disk"  
capability ?

(having burnt myself once ... real badly.... this is something i  
really would like to see.....)


kind regards
