Hey again i havent had much time to play with it but my main mis
understanding was in your post:
tree operation_type = build_method_type_directly (class_t, void_type_node,
NULL_TREE);
tree operation = build_decl(BUILTINS_LOCATION, FUNCTION_DECL,
get_identifier("MyOperation"), operation_type);
tree parm = build_decl (BUILTINS_LOCATION, PARM_DECL, get_identifier("this"),
build_pointer_type(class_t));
tree ptr_obj = build1(ADDR_EXPR, build_pointer_type(TREE_TYPE(object)),object);
tree __call_expr = build_call_expr(__field2, 1, ptr_obj);
What is your __field2 ? is this your function in your record_type for
your class? And if so what way do you declare it do you do build_decl
(function_decl) or is it Method_type ?
I really should play around with this now.
