I was able to just reuse the c-decl.c example: but i have to use: TREE_STATIC (address) = 1; TREE_READONLY (address) = 1; DECL_ARTIFICIAL (address) = 1; on the tmp_var or i get some error when it comes to varasm.c So basically i had to: tree type = build_array_type (char_type_node, build_index_type (size_int ( IDENTIFIER_LENGTH (DECL_NAME(decl)) ))); type = build_qualified_type (type, TYPE_QUAL_CONST); gpy_preserve_from_gc (type); tree str = build_string (IDENTIFIER_LENGTH (DECL_NAME(decl)), c_ident); TREE_TYPE (str) = type; Then MODIFY_EXPR with a tmp_var assigned to str; and i can use that tmp_var to access the string. Thanks Ian!
