Please see my first post in this thread.

I've previously ported Fortran code from OpenVMS to gfortran on OS X, 
so that's certainly feasible for at least some Fortran code.  Whether 
the gcc source code port might or would be feasible with the Fortran 
code the OP is working with here, I do not know.   Whether the existing 
gfortran port is sufficient for the OP's particular needs — or if the 
OP or somebody else around is in a position to port and test and 
package and support the latest gfortran pieces — is also not known.

The last version of gcc I met for VMS was very old.  Specifically went 
looking for gcc for inclusion on the last Freeware, too.

gnv does not use the gcc tools; it uses wrappers around the HP compilers.

I don't know of an llvm port for OpenVMS.

Haven't seen a gcc or llvm discussion on the GNV lists, either.

I don't expect to see HP provide significant standards-level updates to 
the compilers or a project or plans to port open-source compilers on 
the OP's likely schedule, as that's the sort of detail that a marketeer 
would want to have discussed in the roadmaps and marketing, if the 
project is on target for a release in the near future.

OP has the reached the usual questions and discussions and the 
uncomfortable and potentially expensive decisions that various 
customers I've worked with have also encountered in recent years.  This 
is usually a porting project, sometimes of newer or different tools to 
the target platform, and variously of porting the application code to a 
different target platform.  Not fun.  (Well, not fun if you're in 
management and thus paying for all this port-age.  Can be fun if you're 
working on porting the code.)  Not cheap.
