OK for the trunk - and after some grace period - for the 4.6 branch?
Yes.
Do you think we could have a case where we have to delay module namespace
resolving as well (which we can't as we have to generate mod files)?
Committed as Rev. 172718.
Thanks for the review. I don't think delaying the module namespace makes
sense. In terms of the Fortran language, each module and each
subroutine/function/PROGRAM/BLOCK have their own scope. Thus, in
principle, a Fortran compiler does not know about any other item in the
program. As modules might be needed later, it makes sense to resolve
them in the initial order - and immediately.
The global view is only needed at resolve stage for argument checking
(i.e. diagnostics). For the code generation that's different. At that
stage one needs a global (whole file) view as the middle end regards
everything as a single translation unit.
