SUMMARY: pentium optimized debian discussion
It's been a long thread. Here's what've come up so far:
Speed increases of pentium optmized binaries:
- My tests whow around 15%.
- 50% increase one one program claimed.
- The pgcc group claims 5% to 15%, 30% in some cases. This is probably lower
for egcs, it's not as aggressive.
- No-one has indicated that they think these speed increses too low to make
the project not be worthwhile.
- "pentium" is a trademark of intel.
- Intel may dislike use of pentium, they are required by law to enforce
- Debian-ultrasparc has been renamed to debian-ultralinux because of
- egcc does use pentium ("-mpentium") to identify this optimization, not
- It's possible that the pentium optimizations will also make programs run
faster on pentium II, and on pentium clones (586 machines). Noone knowns.
I'd suggest, if anyone can find a noticible speed increase on a pentium
clone, we bypass the whole problem and call it 586. It may be worthwhile to
call it 586 anyhow so we don't have to worry about intel.
- We've decicded that it is better implemented by an architecture, rather
than the Optimization tag hack.
- I have made the necessary changes to dpkg so it looks at
- This change will likely help other ports as well, though I haven't heard
- I've posted my changes and a patch to debian-dpkg for review and comment.
No objectors so far.
If we can clear up the naming problem and people agree with the points in
this summary about speed, then I think we can set up the architecture on the
ftp site now.
