Abstract
Techniques for reducing the cost of dynamic class loading and initialization checks in compiled code are provided. Virtual machine instructions are compiled into one or more native machine instructions even if required runtime execution information is unavailable at the time of compilation. The native machine instructions include placeholder data where the required runtime execution information should be. The native machine instructions are overwritten with a native machine instruction that transfers control to a section of code or stub that, at runtime execution, replaces the placeholder data with the required runtime execution information and execution continues.
