AbstractRegisterImpl クラス(AbstractRegister)

AbstractRegisterImpl

概要(Summary)

Assembler クラス用の補助クラス.

オペランドとしての「レジスタ」を表すクラスの基底クラス (See: here for details).

なお, 具体的な RegisterImpl クラス (AbstractRegisterImpl のサブクラス) は cpu/ 下で定義されている (See: hotspot/src/cpu/${cpu}/vm/register_${cpu}.hpp).

    ((cite: hotspot/src/share/vm/asm/register.hpp))
    // The super class for platform specific registers. Instead of using value objects,
    // registers are implemented as pointers. Subclassing is used so all registers can
    // use the debugging suport below. No virtual functions are used for efficiency.
    // They are canonicalized; i.e., registers are equal if their pointers are equal,
    // and vice versa. A concrete implementation may just map the register onto 'this'.

    class AbstractRegisterImpl {

なお AbstractRegister という型も使われるが, これは AbstractRegisterImpl* のこと.

    ((cite: hotspot/src/share/vm/asm/register.hpp))
    typedef AbstractRegisterImpl* AbstractRegister;
