Bugzilla Bug 86142

Acovea doesn't link with gcc 4.0.0_beta20050305, complaining about a missing
definition of BOGUS_RUN_TIME. The following patch solves that, and makes it
possible to use acovea to tune your CFLAGS with gcc 4.0.0.

ebuild that applies the patch, it works for me...

configuration file

This is a sample configuration file that I made for my laptop (pentium-m). Some
options that should be included in gcc-4.0 according to the docs are not
recognised, so I commented them out. I hardcoded the path to the right compiler
(4.0.0_beta20050305) so it can be used with the default compiler different from
gcc4. All the benchmarks work, except for the treebench, but treebench never
worked for me...

Patch to make treebench work with the malloc-check in glibc

This patch makes treebench work with glibc compiled with malloc-check
activated.
This is the only benchmark where I have seen succesfull tree-vectorisation, so
it would be nice to be able to use this benchmark. This fix is non-gcc4
specific.

Bumping the package to the newest version would probably solve this problem. 
There are newer versions of libacovea, libcoyotl, and libevocosm on
http://www.coyotegulch.com/products/acovea/index.html  I didn't try it, but he
tested GCC4 with it, so I'm assuming he fixed the compilation issues.  Note, the
location of the files has changed, so the ebuilds will need to be updated
slightly.  There is also a new package on the site as well.

the new version solves the problem of not building on gcc 4.0, but the
treebench
problem still exists, it won't run on either gcc 3.4 or 4.0.
The patch works for the new version as well

Re-assign. 

acovea-5.1.1 is now in the tree, let me know if there are any more issues.
Thanks!
