Discussion on comp.compilers notwithstanding :-), I'm looking for a basic 
Fortran to Fortran function inliner.  The application is not demanding, 
and the relevant code is yet to be written, so I am not seeking an 
all-singing, all-dancing tool.  Any suggestions welcome.

Some background for the curious:  I'm rewriting some ancient code for 
modelling seismic wave propagation in stratified media, and I'd like to
be able to run the code on our Convex system as well as my workstation.
Good program design and my intention to develop certain aspects of the
program suggest that I should code the main algorithm - a series of
manipulations of small matrices - as a collection of subroutine calls.
The algorithm is certainly vectorizable, but the Convex compiler is 
apparently incapable of vectorizing a loop which contains such calls.  
An inliner would allow me to write and test the code in a legible, 
maintainable fashion on my workstation, and to transform it into 
vectorizable form for subsequent 'production' use on the Convex.  
I concede that I could perhaps produce readable code by careful use of 
a macro pre-processor, but I would prefer to construct modular code in
standard Fortran.

Thanks for your attention
