Class のロード/リンク/初期化 ： リンク処理 (2) ： リンク処理の流れ

概要(Summary)

クラスのリンク処理は instanceKlass::link_class() (より正確には instanceKlass::link_class_impl()) で行われる.

リンク処理では, 以下の処理が行われる.

• バイトコードの verification 処理 (See: here for details)

• バイトコードの rewrite 処理, 及び rewrite に伴う再配置 (See: here for details)

• クラス内の vtable, itable の作成

処理の流れ (概要)(Execution Flows : Summary)

instanceKlass::link_class()
-> instanceKlass::link_class_impl()
   -> (1) バイトコードの verification を行う
          -> instanceKlass::verify_code()
              -> Verifier::verify()
                 -> (See: here for details)

      (1) バイトコードの rewrite 処理を行う
          -> instanceKlass::rewrite_class()
             -> Rewriter::rewrite()
                -> (See: here for details)

      (1) 
          -> instanceKlass::relocate_and_link_methods()
             -> Rewriter::relocate_and_link(instanceKlassHandle this_oop, TRAPS)
                -> (See: here for details)

      (1) vtable 及び itable を生成する
          -> klassVtable::initialize_vtable()
          -> klassItable::initialize_itable()
