Compiler Analysis: 3.3, 3.4, or tree-ssa?

A couple months ago, I gave a preliminary report on my project to
analyze the effectiveness of gcc optimizations via an evolutionary
algorithm. At that time, the responses I received lead me to spend time
reworking my research code into soemthing a bit more formal and modular.
Where the original framework was gcc and Intel specific, the current
program is both compiler and platform independent.
Now that I'm ready to publish Acovea (Analysis of Compiler Options Via
Evolutionary Algorithm), I'm wondering which version of gcc I should
analyze.
3.3.x is the current release; analyzing it would provide a baseline, but
any discoveries are unlikely to have much impact on 3.3's development at
this point.
3.4 is in active development, and is the subject of my current tests.
I've discovered a number of anomalies and an ICE; I'll report the
results here as soon the the entire test set is complete.
Should I also analyze tree-ssa, aka 3.5? Is there value in comparing
results from 3.3, 3.4, and 3.5?
Considered opinions will be appreciated.
