Code generation: How to define file-scope static variables?

[Robert Dubner]

I am part of a team working on a COBOL front end for GCC.

By reverse engineering other front ends, I learned, some months ago, how
to create a function_decl GENERIC node that is the root of a GENERIC tree
describing an entire function.   

By calling the routine cgraph_node::finalize_function() with that
function_decl, the assembly language for that function is created, and all
is well.

But now I need to be able to create the equivalent of a file-scope static
variable in C.

This C program file:

//////////////////
static int dubner_at_work = 123454321;
int main(int argc, char **argv)
  {
  }
//////////////////

produces, in part, this assembly language:

###############
        .file   "ccc.c"
        .text
        .data
        .align 4
        .type   dubner_at_work, @object
        .size   dubner_at_work, 4
dubner_at_work:
        .long   123454321
        .text
        .globl  main
        .type   main, @function
        [...]
###############

In my own GENERIC generation code, I believe that I am creating a proper
translation_unit_decl that contains the block and the vars nodes for
specifying "dubner_at_work".

But I have been unable, after several days of looking, to figure out the
equivalent of "cgraph_node::finalize_function" for a
translation_unit_decl.  The resulting assembly language doesn't have a
definition for "dubner_at_work".

Can anybody describe how I can tell the downstream processing that I need
the translation_unit_decl to actually define storage?

Thanks very much,

Bob Dubner.
