I agree with that.

Can't we separate the projects? AFAIKS, there are a few issues:

a) parse the directives and make sure they are correct
b) propagate information to the middle end
c) decide how to deal with OpenMP in the middle end

All those things look to me pretty independent.

For instance, we (or some of us?) can start with the parser, a first step
would be to parse the openmp directives and deciding whether they are
correct or not, and ignoring them. When this is complete, a second step
would be to propagate them to the middle end and so forth.

Thoughts?
