Hello!
I am writing some plugin and I have a problem with creating a function call.
For creating call (by gimple_build_call) I have to specify the
function_decl tree.
How can I get the list of all declarations (that used not only in
current function, I need get the all available declarations also from
included headers) in order to lookup by identifier function_decl which
I want to call?
For example:
/* lookup_fn_decl - It is some pseudo-function which searches a
function declaration by identifier */
/* all_decl_list_head - It is pointer to the head list of all
declarations. It is what I need */
tree found_decl = lookup_fn_decl(all_decl_list_head, "pthread_create");
if (found_decl == NULL) {
/* We need to create decl */
} else {
....
}
