The new GNU Fortran 95 compiler (gfortran) is deliberately tied to
tree-ssa; unless I'm mistaken, Fortran 95 support will only exist in
mainline GCC if tree-ssa becomes mainline.
I strongly doubt that's correct. A front-end that's designed to use tree-ssa
can very easily be reworked to use the 3.4 function-at-a-time approach. (The
other direction is harder, but not even that much harder. The hard case is
converting a front end that directly generates RTL into using tree-ssa.)
There's no reason to tie the release schedule of such a project to the
release schedule of tree-ssa: if the latter happens to slip significantly,
gfortran can still be released as a 3.4-based front end.
