Method Detail

singleton

public static FrameAccess singleton()

readReturnAddress

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

writeReturnAddress

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

returnAddressSize

public static int returnAddressSize()

stackPointerAdjustmentOnCall

public abstract int stackPointerAdjustmentOnCall()

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

savedBasePointerSize

public abstract int savedBasePointerSize()

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).

wordSize

public static int wordSize()

uncompressedReferenceSize

public static int uncompressedReferenceSize()

getWordKind

public static jdk.vm.ci.meta.JavaKind getWordKind()

getWordStamp

public static org.graalvm.compiler.core.common.type.Stamp getWordStamp()
