Sort of:


To the best of my knowledge, the only Fortran 90 grammar generally
available at no cost is that of Eli, see


http://www.cs.colorado.edu/~eliuser/


and related pages. I have not tried using Eli, but, although the nominal
grammar is apparently not in YACC form, I believe they use YACC for
intermediate processing (i.e., they process their grammar to produce a
YACC compatible grammar), and it may be possible to use either the
original Eli grammar or the YACC compatible intermediate form for your
purposes.


A number of academic researchers that are doing work on parallelizing
Fortran code nominally work on supersets of Fortran 77 that are
gradually incorporating Fortran 90 features. It may be that one of them
has something close to what you want. Possiblitities include HPF and
SUIF

It may be that commercial vendors have grammars they are willing to
share with academic users, but most of those will involve either
handwritten parsers, or their own proprietary tools. As NAG has been the
only vendor that relied on C intermediate code, I suspect that they are
the most likely vendor to have what you want.


You may also want to check on PCCTS, JCC and other tools
