I am much more worried about passes and plugins (and I am very

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.
Is the plugin machinery intended to eventually allow new (GPL
compatible) backends to be used? It would be nice to make llvm-gcc be
a plugin.
