public class SpecialCompiler
extends Object
extends Object

SpecialCompiler is a wrapper for compiling specialized byte code. It accepts an instance of ExecutionState, generates the specialized byte code, and compiles it to machine code instructions.

Constructor Summary
`SpecialCompiler()`

Method Summary
`static CompiledMethod`	`baselineCompile(ExecutionState state)`
`static CompiledMethod`	`optCompile(ExecutionState state)` 1. generate prologue PSEUDO_bytecode from the state. 2. make new bytecodes with prologue. 3. set method's bytecode to specialized one. 4. adjust exception map, line number map. 5. compile the method. 6. restore bytecode, exception, linenumber map to the original one.
`static CompiledMethod`	`recompileState(ExecutionState state, boolean invalidate)` recompile an execution state
