Yeah - that was me... Fact is we had a discussion about debug information earlier this year from which I took the conclusion that most people would appreciate an on-the-side representation to address the most limiting design issue of GCCs tree representation (only one variable per SSA_NAME to track). So I had the impression you worked in that direction and offered help. Now, you seemed to have come to the conclusion that this approach would not help your goal and started on a different route. Now the "mistake" maybe was to before starting this not to revive the former discussion based on your findings and elaborate on your goals. (I realize this is the way development for GCC works most of the time, but this is not what I consider good practice for open source development) Now - I think your goal is valid, and the choice of implementation might even be the best one for it. But we (the GCC community) have not yet decided if the combination of "your goal" and "this best implementation" is what we want. (I haven't decided myself either ;)) So my suggestion for you is to continue with your implementation and produce a white paper about your design (which you ideally would present during the next GCC summit, where we should do a discussion on this topic in some form). We (myself and Matz) will continue to implement what is "our goal" (because we internally committed to it, and to see limitations or problems with the approach) and possibly also will present about its outcome at the summit. Thanks, Richard.
