Method Summary

Modifier and TypeMethod and Description
public ClosestSymbol
closestSymbolToPC()

Overrides sun.jvm.hotspot.debugger.cdbg.basic.BasicCFrame.closestSymbolToPC.

Implements sun.jvm.hotspot.debugger.cdbg.CFrame.closestSymbolToPC.

For the loadobject in which the PC lies, fetch the name of the closest exported symbol and the distance of the PC to that symbol.

private Address
getNextCFA(DwarfParser nextDwarf, ThreadContext context)

private Address
getNextPC(boolean useDwarf)

public static LinuxAMD64CFrame
getTopFrame(LinuxDebugger dbg, Address rip, ThreadContext context)

private boolean
isValidFrame(Address nextCFA, ThreadContext context)

public Address
localVariableBase()

Implements sun.jvm.hotspot.debugger.cdbg.CFrame.localVariableBase.

Gets the base pointer in this frame from which local variable offsets in the debug info are based.

public Address
pc()

Implements sun.jvm.hotspot.debugger.cdbg.CFrame.pc.

Get the program counter of this frame

public CFrame
sender(ThreadProxy thread)

Implements sun.jvm.hotspot.debugger.cdbg.CFrame.sender.

Returns null when no more frames on stack

public ClosestSymbol closestSymbolToPC()

Overrides sun.jvm.hotspot.debugger.cdbg.basic.BasicCFrame.closestSymbolToPC.

Implements sun.jvm.hotspot.debugger.cdbg.CFrame.closestSymbolToPC.

Doc from sun.jvm.hotspot.debugger.cdbg.CFrame.closestSymbolToPC.

For the loadobject in which the PC lies, fetch the name of the closest exported symbol and the distance of the PC to that symbol. Returns null if the PC was not within any of the loadobjects of the target process. FIXME: specify whether this is mangled/demangled.

public Address localVariableBase()

Implements sun.jvm.hotspot.debugger.cdbg.CFrame.localVariableBase.

Doc from sun.jvm.hotspot.debugger.cdbg.CFrame.localVariableBase.

Gets the base pointer in this frame from which local variable offsets in the debug info are based. Typically this is the base-of-frame pointer (EBP on x86, FP/I6 on SPARC).

pcback to summary
public Address pc()

Implements sun.jvm.hotspot.debugger.cdbg.CFrame.pc.

Doc from sun.jvm.hotspot.debugger.cdbg.CFrame.pc.

Get the program counter of this frame

public CFrame sender(ThreadProxy thread)

Implements sun.jvm.hotspot.debugger.cdbg.CFrame.sender.

Doc from sun.jvm.hotspot.debugger.cdbg.CFrame.sender.

Returns null when no more frames on stack
