Do you have any specifics? I imagine it would be pretty easy to find
interest for this project. I'd suggest that you come up with a detailed
proposal and post it on this list for comment. You may be interested in
the tree-SSA infrastructure, see:
http://gcc.gnu.org/projects/tree-ssa/
However, if you are just looking for suggestions, there are a number of
C++ scientific libraries that would be interested in increasing
performance, some of which are listed below.
- ginac (symbolic algebra)
http://www.ginac.de/
- pooma (parallel scientific computation)
http://www.codesourcery.com/pooma/pooma
- goose (stats)
http://www.gnu.org/software/goose/goose.html
- itk (algo parts)
http://www.itk.org
A first step might be doing performance analysis of these libraries,
finding bottlenecks, and then working to resolve these deficiencies.
There are, or have been, issues with performance of C++'s complex type.
Perhaps Joe Buck could give more information on this.
There are people on this list (or gcc developers) that seem to be
interested in this subject. Off the top of my head, these people include
Roger Sayle, Scott Synder, Scott Robert Ladd, Gabriel Dos Reis, etc. I'm
sure there are others.
good luck,
