Hello Phill,
I declare the operation as a build_decl like this:
tree myOperation1_decl = build_decl(BUILTINS_LOCATION, FUNCTION_DECL,
get_identifier("MyOperation1"), myOperation1_type);
tree myOperation1_tree = create_operation1(myClass_type, myOperation1_decl);
DECL_CONTEXT(myOperation1_tree) = myClass_type;
In create_operation1 function, I build the body of the operation that modify the
value of one attribute. thus filed2 is my attribute
here is the gimple that I produce.
the param is for the "this" to acceed the attribute (this.attribute)
main ()
gimple_bind <
<unnamed-signed:32> D.34;
struct MyClass x;
gimple_call <MyOperation1, NULL, &x>
gimple_call <MyOperation2, NULL, &x>
gimple_assign <integer_cst, D.34, 0, NULL>
gimple_return <D.34>
>
MyOperation2 (struct MyClass * this)
gimple_bind <
gimple_assign <integer_cst, this->MyAttribute2, 15, NULL>
gimple_return <NULL>
>
MyOperation1 (struct MyClass * this)
gimple_bind <
gimple_assign <integer_cst, this->MyAttribute1, 10, NULL>
gimple_return <NULL>

Do not hesitate if you have other questions,
Asma

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.
