Method Detail

readReturnAddress

public org.graalvm.nativeimage.c.function.CodePointer readReturnAddress(org.graalvm.word.Pointer sourceSp)

Specified by:

readReturnAddress in class FrameAccess

writeReturnAddress

public void writeReturnAddress(org.graalvm.word.Pointer sourceSp,
                               org.graalvm.nativeimage.c.function.CodePointer newReturnAddress)

Specified by:

writeReturnAddress in class FrameAccess

savedBasePointerSize

public int savedBasePointerSize()

Description copied from class: FrameAccess

Returns the size in bytes of the saved base pointer in the stack frame. The saved base pointer must be located immediately after the return address (if this is not the case in a new architecture, bigger modifications to code like the Deoptimizer is required).

Specified by:

savedBasePointerSize in class FrameAccess

stackPointerAdjustmentOnCall

public int stackPointerAdjustmentOnCall()

Description copied from class: FrameAccess

Gets the amount by which the stack pointer is adjusted by a call instruction.

Specified by:

stackPointerAdjustmentOnCall in class FrameAccess
