Method Detail

visitFrame

public boolean visitFrame(org.graalvm.word.Pointer sp,
                          org.graalvm.nativeimage.c.function.CodePointer ip,
                          CodeInfo codeInfo,
                          DeoptimizedFrame deoptFrame)

Description copied from interface: StackFrameVisitor

Called for each frame that is visited. Note that unless this method is annotated with Uninterruptible or executing within a safepoint, the frame on the stack could be deoptimized at any safepoint check. Nevertheless, the passed codeInfo remains valid for accessing information about the code at the (possibly outdated) instruction pointer (this is ensured by the caller).

Specified by:

visitFrame in interface StackFrameVisitor

Parameters:

sp - The stack pointer of the frame being visited.

ip - The instruction pointer of the frame being visited.

codeInfo - Information on the code at the IP, for use with CodeInfoAccess.

deoptFrame - The information about a deoptimized frame, or null if the frame is not deoptimized.

Returns:

true if visiting should continue, false otherwise.

logFrame

protected void logFrame(Log log,
                        org.graalvm.word.Pointer sp,
                        org.graalvm.nativeimage.c.function.CodePointer ip,
                        CodeInfo codeInfo,
                        DeoptimizedFrame deoptFrame)

logFrameRaw

protected static void logFrameRaw(Log log,
                                  org.graalvm.word.Pointer sp,
                                  org.graalvm.nativeimage.c.function.CodePointer ip)
