Now all the devel team has to do is convert everything to 64-bit and they got themselves a G5 :D

From the info I got from the dev mailing list and the wiki, AltiVec is software emulated at the moment. It should run on a 486 as well as on a P4.

Yes... that should be possible.
I would doubt that. Pear PC will be compiled for a 686 core. That core is very different from a 486 core

yeah, but sometimes bare facts aren't that exciting... :P

Not that anyone gets me wrong: I think it's a huge achievement that PearPC now virtually emulates a G4. If someone had told me so a year ago I probably would not have believed him...

But all this needs time to get where we want it to be. in the meatime it helps to stick with the facts...

don't forget that it compiles for 686+ only if you compile it optimized, the non-optimized build is plain ia-32 code which should run perfectly (but slowly) on a 486 or even a 386 (even slower).

I didn't mean just an optimisation for 686. Some programs refuse to run if they do not have a P6 core. Try running some versions of Sci Tech Display Doctor on a regular pentium, for example. It throws skitz and then says it won't work cos it specifically calls for 686 instructions. I am not saying that PearPC is like this, but it might be.

well, sebastian said that pearpc should run ok (but slowly) on a 486 as on a p4, and he's the main developer, so i would listen (i don't want to go and test my pearpc on the 486 a few meters away through a parallel cable)

Well , G3 emulation on 486....*faints*..Well , it will run slow...and PearPC really rocks with Velocity Engine...(G4 emulation)...

Hmm for some reason I am not getting the watched topic E-mails anymore....I'll have to run that past clockwise...ANYWAYS!

23 July 04 is updated....and I had family issues the other night that stopped me from loging on and doing it (didn't even touch the computer)...ALSO...

A few people have asked about *nix builds.....well if you send me the flags for it or a complete script for CYGWin on how to do it but your too lazy I'll do it for everyone....there that is my offer....

Is there a way to take advantage of both SSE and 3DNow! Pro in the Athlon XP Processors?

I have to apologize to everyone I was unable to build really anything today 23-24 July cause I had a windows issue. However I was able to compile and build a beta Altivec build (say that three times fast) and a Beta Altivec with fixed SDL to allow fullscreen....take alook at my site and the links are on the front.

what flags you you guys using for the optimized builds

i started with

Code: Select all

-march=pentium3 -O3 -pipe -fomit-frame-pointer
for my computer..along with the other default flags the config file sets up

here's my final setup for gcc 3.4

Code: Select all

-march=pentium3 -O3 -pipe -fomit-frame-pointer -momit-leaf-frame-pointer -ftracer -fno-crossjumping -mfpmath=sse -maccumulate-outgoing-args -fmove-all-movables -freduce-all-givs -ffast-math -fprefetch-loop-arrays -fforce-addr -falign-functions=4 -funroll-loops -fweb -Wundef -Wall -g -D_LARGEFILE_SOURCE -fsigned-char -D_FILE_OFFSET_BITS=64
the build made with the latter flags was 5 seconds faster booting darwin

well, i used -march=athlon-4 -O3 and it did run faster (don't ask me about darwin, but osx loaded 10-15 seconds faster)

using the first with just -march=pentium3 -O3 -pipe -fomit-frame-pointer vs. the really obnoxiusly long list of flags...i noticed the animations in OS X ran much smoother...mainly the menu fading....i'm quite impressed myself

I don't have a server right now to put it on

It was just a .2 release version anyways

I can make them using those flags for any processor...although i dunno what flags the other people making builds use so i can't gurantee a performance increase

Ok, it is PPC_diggers responsibility to teach everyone how to use CYGwin now...sound fair enough?

I want to help with the PearPC development as much as possible, so if someone posts a tutorial on how to compile using CYGwin then I will take the time to read it.

Then if people want I can compile the code and even try new patches to see if they work.

I think that all the people who can should test the patches, as these will help to add features and remove bugs.
