Class Summary |
| AdjustBCIndexes |
OSR_AdjustBCIndex is an optimizing phase performed on HIR. |
| BytecodeTraverser |
BytecodeTraverser does depth first search on a bytecode
array, determines the type information of locals and stacks at
Interesting point. |
| EncodedOSRMap |
EncodedOSRMap provides the similar function as GC map
in OptMachineCodeMap. |
| ExecutionState |
|
| ExecutionStateExtractor |
A ExecutionStateExtractor extracts a runtime state (VM scope descriptor)
of a method activation. |
| LocalRegPair |
An LocalRegPair keeps the type information and location of
a local variable/stack slot from byte code to machine code. |
| MethodVariables |
A class to hold variables for a method at one program point. |
| ObjectHolder |
ObjectHolder helps the specialized prologue to load reference
get around of GC problem |
| OSRMapIterator |
An iterator over an encoded OSR map. |
| OSRProfiler |
Maintain statistic information about on stack replacement events |
| SpecialCompiler |
SpecialCompiler is a wrapper for compiling specialized byte code. |
| TypeStack |
Utility class used by BytecodeTraverser. |
| VariableElement |
An instance of VariableElement represents a byte code variable
(local or stack element). |
| VariableMap |
VariableMap, non-encoded yet
VariableMap ---> LinkedList of VariableMapElement
VariableMapElement ---> (OsrPoint, LinkedList of MethodVariables)
MethodVariables ---> (Method, PC, List of LocalRegTuple)
LocalRegTuple ---> ( LocalNum, regOp, Type ) or ( StackNum, regOp, Type )

| VariableMapElement |
Variable map element (osr instruction, LinkedList MethodVariables) |
