Tree SSA has always been very conventional. If I had wanted to do
research, I would have started with my Concurrent SSA work.
The metrics and specifications have always been documented in the
project's web page (http://gcc.gnu.org/projects/tree-ssa/). Also, see
the papers I presented last year at Nordu2003 and GCC Summit.
I agree that some of the goals have only partially been met. Hence my
RFC to gather feedback from the community and weigh the pros and cons of
merging into mainline at this stage.
The discussion is also useful to discuss the status of the work in
detail, as well. As Kaveh pointed out, I failed to provide several
details that I was just taking for granted.
