Various GCC compared (2.95.3 - 3.5-20040523) III

[Rene Rebe <rene at rocklinux-consulting dot de>]

Hi all,

My next "preleminary" results are now available for an athlon-xp:

 http://rocklinux-consulting.de/new-bt.png

(up-to-date g3 results will follow today after a sleep cycle and will
be named new-??-g3.png when available)

Notes:

 * -athlon results are built with "-O2 -mcpu=athlon-xp (or athlon or
   i686 or -xK respectively - depending on the compilers support)"
   The other results are built with "-O2" only for reference
 * There are some up and downs in the runtime. New versions do not always
   produce faster code.
 * my gcc-3.5-20040523 _has checking_ disabled
   there clearly is a compile time speed regreesion for all tests
 * The Botan (C++) bench runtime for 3.5 is not very low - but just
   not yet present since g++-3.5-20040523 ICEs. Maybe this is due to
   incorrect template code I used -fpermissive to work around - I'll
   try to fix the code properly and see if it does not ICE anymore.

Some notes:

 * all run GNU/Linux - Athlon-XP 2500
 * all gcc builds are bootstrap builds, that is no profiledbootstrap
   (if time permits I will add seperate results with profiledbootsrap)
 * test description can be found at:

   http://www.rocklinux-consulting.de/oss/openbench/tests.html

Tests I will add later:
   ogg/vorbis: compression decompression

I still search for a more C++ testsuits I could incooperate (xpdf was
proposed).

Any comments welcome!

Sincerely yours,
  René Rebe
