これらは, HotSpot 内部でよく参照される名前(クラス名, メソッド名, 型を表すシグネチャ文字列, 等)に高速にアクセスするためのユーティリティ・クラス.
vmSymbols は, HotSpot 内部でよく使われる Symbol オブジェクトに高速にアクセスするためのユーティリティ・クラス (例えば, java_lang_Object や java_util_Arrays といったよく使われるシンボルに対して簡単かつ高速にアクセスできる. また型シグネチャに付いても, 例えば long_long_signature で "(J)J" が参照できる, 等)
vmIntrinsics は, よく使われるメソッドに対してそれを一意に識別するための整数値(ID)を割り当てている名前空間. 内部的に vmSymbols を用いて実装されている.
((cite: hotspot/src/share/vm/classfile/vmSymbols.hpp))
// The class vmSymbols is a name space for fast lookup of
// symbols commonly used in the VM.
//
// Sample usage:
//
// Symbol* obj = vmSymbols::java_lang_Object();
HotSpot 内部でよく使われる Symbol オブジェクトへの参照を納めた名前空間(AllStatic クラス).
((cite: hotspot/src/share/vm/classfile/vmSymbols.hpp))
// Class vmSymbols
class vmSymbols: AllStatic {
HotSpot 内の様々な箇所で使用されている (#TODO).
一覧は以下の通り.
(なお VM_SYMBOLS_DO() というマクロが定義されており, これを使うと vmSymbols 全体に対するメタな処理を定義することが出来る. (例えば「これらに対応するメソッドを定義する」とか「この一覧を iterate して何か処理を行う」とか))

HotSpot 内部でよく用いられるメソッドに対して, それを一意に示す定数値を定義した名前空間(AllStatic クラス).
((cite: hotspot/src/share/vm/classfile/vmSymbols.hpp))
// VM Intrinsic ID's uniquely identify some very special methods
class vmIntrinsics: AllStatic {
HotSpot 内の様々な箇所で使用されている (#TODO).
(例えば, JIT Compiler によるインライン展開処理で 「標準ライブラリ内の特定のメソッドに対してはそのメソッドに特化した展開処理を行いたい」といった場合に, メソッドを特定するために vmIntrinsics の ID による比較を行っていたりする. (See: here for details))
vmIntrinsics に登録されているメソッドには vmIntrinsics::ID 型の一意な整数値(ID)が振られる.
そして vmIntrinsics クラス内には, それぞれの vmIntrinsics::ID 値を表す定数(enum値)が定義されている (e.g. vmIntrinsics::dsin, vmIntrinsics::_hashCode, vmIntrinsics::fillInStackTrace, etc).
(なお, vmIntrinsics::ID 型は以下のように定義された enum 値. この定義では後述の VM_INTRINSICS_DO() マクロが使用されている)
((cite: hotspot/src/share/vm/classfile/vmSymbols.hpp))
enum ID {
_none = 0, // not an intrinsic (default answer)
#define VM_INTRINSIC_ENUM(id, klass, name, sig, flags) id,
VM_INTRINSICS_DO(VM_INTRINSIC_ENUM,
VM_SYMBOL_IGNORE, VM_SYMBOL_IGNORE, VM_SYMBOL_IGNORE, VM_ALIAS_IGNORE)
#undef VM_INTRINSIC_ENUM
ID_LIMIT,
LAST_COMPILER_INLINE = _prefetchWriteStatic,
FIRST_ID = _none + 1
};
(なお, メソッドの方からは ciMethod::intrinsic_id() や methodOopDesc::intrinsic_id() でそのメソッドの vmIntrinsics::ID 値を確認できる)
一覧は以下の通り.
(なお VM_INTRINSICS_DO() というマクロが定義されており, これを使うと vmIntrinsics 全体に対するメタな処理を定義することが出来る. (例えば「これらに対応するメソッドを定義する」とか「この一覧を iterate して何か処理を行う」とか))
(VM_INTRINSICS_DO() 内では, 各メソッドの情報は 5-tuple で表現される. 具体的には "(vmIntrinsics::ID 値, クラス名, メソッド名, 型を表すシグネチャ文字列, AccessFlags 情報を示す定数値)" という tuple. このタプルに含まれる名前(クラス名, メソッド名, シグネチャ文字列)には vmSymbols を用いている (というか vmSymbols として intern されてないといけないとのこと))
((cite: hotspot/src/share/vm/classfile/vmSymbols.hpp))
// Here are all the intrinsics known to the runtime and the CI.
// Each intrinsic consists of a public enum name (like _hashCode),
// followed by a specification of its klass, name, and signature:
// template(<id>, <klass>, <name>, <sig>, <FCODE>)
//
// If you add an intrinsic here, you must also define its name
// and signature as members of the VM symbols. The VM symbols for
// the intrinsic name and signature may be defined above.
//
// Because the VM_SYMBOLS_DO macro makes reference to VM_INTRINSICS_DO,
// you can also define an intrinsic's name and/or signature locally to the
// intrinsic, if this makes sense. (It often does make sense.)
//
// For example:
// do_intrinsic(_foo, java_lang_Object, foo_name, foo_signature, F_xx)
// do_name( foo_name, "foo")
// do_signature(foo_signature, "()F")
// klass = vmSymbols::java_lang_Object()
// name = vmSymbols::foo_name()
// signature = vmSymbols::foo_signature()
//
// The name and/or signature might be a "well known" symbol
// like "equal" or "()I", in which case there will be no local
// re-definition of the symbol.
//
// The do_class, do_name, and do_signature calls are all used for the
// same purpose: Define yet another VM symbol. They could all be merged
// into a common 'do_symbol' call, but it seems useful to record our
// intentions here about kinds of symbols (class vs. name vs. signature).
//
// The F_xx is one of the Flags enum; see below.
//
// for Emacs: (let ((c-backslash-column 120) (c-backslash-max-column 120)) (c-backslash-region (point) (point-max) nil t))
