Having a central driver would certainly help--though only to the extent that anybody listened. I have seen people complain that the gcc developers are ornery and difficult to work with. I've been reading the mailing lists with that in mind, and I actually don't see that very much. However, it only takes a very small number of mean-spirited messages to give that impression. What I do see is that relatively few gcc developers take the time to reach out to new people and help them become part of the community. I also see a lot of external patches not reviewed, and I see a lot of back-and-forth about patches which is simply confusing and offputting to those trying to contribute. Joining the gcc community requires a lot of self-motivation, or it takes being paid enough to get over the obstacles. There is also the matter of the old code base, the lack of a clean separation between passes, and, most important, weak internal documentation. For example, in my view of internal documentation: How to write a new backend: good. Details of RTL IR: adequate. Details of GIMPLE IR: poor. Details of tree IR: poor. How to write a new optimization pass: poor. How to write a new frontend: nonexistent. General overview of compiler source: nonexistent. Overview of internal compiler datastructures: nonexistent. I am as responsible for this state of affairs as anybody. Ian
