I am much more worried about passes and plugins (and I am very
surprised to be almost the only one mentioning passes in plugin
discussions). I feel it is a major issue (not a matter of coding,
much
more a matter of convention & understanding). So far, I have (in MELT
branch) a very unsatisfactory bad solution. I defined a few passes,
which may (or not) be enabled by some plugins. What I would dream is
some machinery to be able to have the plugin ask 'insert my pass
foo_pass after the last pass which construct the IPA SSA tuple
representation' and this is not achievable today.
I think we also need that for general backend use, not only for
plugins. E.g., bt-load.c should move to config/sh, and at startup
time the SH backend should register the pass with the pass manager.
