<grin> but only after duplicating about 20% of the tree-ssa work
(i.e. all function lowering, inlining and part of expansion), and the
generated code would be so horrible that no sane Fortran user would
dare touch it ;-)
Yes of course you might need to use some of the lowering code written
for tree-ssa to lower into older-style trees, but I don't see that as
significant. And I don't understand your last comment: unlike C++,
the important optimizations for Fortran are relatively low-level and
will benefit less from tree-ssa than other languages.
