A mechanism is provided for execution of an instruction having one or more parameters
that need to be resolved at runtime. Instructions being executed may be stored
in non-rewritable storage. The present invention allows costly parameter resolution
to be circumvented during subsequent executions of the same instruction. An interpreter
invokes an optimization module when it encounters an instruction with one or more
associated parameters that need to be resolved at runtime. If the optimization
module determines that resolved values associated with the instruction are available
in a cache, then optimization module obtains resolved values associated with the
instruction from the cache. Resolving parameters into their corresponding object
references is time-consuming and utilizes valuable computer resources. By obtaining
resolved values stored during a previous execution of an instruction, the optimization
module avoids repeatedly resolving parameters associated with an instruction. This
enables efficient execution of an instruction.
