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.
