one thing i found very useful in learning to code gcc front-ends is
added debug_tree (tree) in your gimplify expression lang_hook this
will print debug info about the tree's which get gimplified.

Hello,
thank you very much Ian and Phill, Now it works (I used the debug_tree that I
find also very helpfull especially for the newbies in coding gcc fe ;)
the error comes (as Ian said from the BIND_EXP) I added my 2 var decl to the
same tree (declare_vars) and I used TREE_CHAIN to obtain one tree (just like the
gcalc fe):
tree bind = NULL_TREE;
tree bl = build_block(declare_vars, NULL_TREE, main_fn_decl, NULL_TREE);
DECL_INITIAL(main_fn_decl) = bl;
bind = build3( BIND_EXPR, void_type_node, BLOCK_VARS(bl), NULL_TREE, bl );
now I want to add a class (a record type) with attributes and methods and after
in the main I will add an object of type myclass and call one of the methods.
shoud I add another bind ?
is there a documentation on how to write this using generic other than the
tree.def ?
I will try to do it and if I get erros (hope not) I will certainly ask in the
gcc-help mailing list ;)

Hello,
here I am ;)
I tried to add a class with attribute and method
my problem is that the method is never added to the TYPE_METHOD list of the
RECROD_TYPE:
tree class_type = make_node(RECORD_TYPE);
TYPE_PACKED(class_type) = false;
TYPE_NAME(class_type) = get_identifier("MyClass");
tree __field1 = build_decl(BUILTINS_LOCATION, FIELD_DECL,
get_identifier("MyAttribute"), integer_type_node);
DECL_CONTEXT(__field1) = class_type;
DECL_PACKED(__field1) = false;
TYPE_FIELDS(class_type) = __field1;
tree __field2 = build_decl(BUILTINS_LOCATION, FUNCTION_DECL,
get_identifier("MyOperation"), void_type_node);
DECL_CONTEXT(__field2) = class_type;
TREE_PUBLIC(__field2) = true;
DECL_ARGUMENTS(__field2) = NULL_TREE;
DECL_PACKED(__field2) = false;
TYPE_METHODS(class_type) = __field2;
layout_type(class_type);
rest_of_type_compilation(class_type, 1);
debug_tree(class_type);
the result of the debug class_type is : (with no ref to MyOperation )

did I miss sth to add the method in the record type ?
thanks
