Interface StackOverflowCheck.OSSupport

Enclosing interface:

StackOverflowCheck

public static interface StackOverflowCheck.OSSupport

Operating system abstraction: The OS needs to provide end of the physical stack memory. Note that currently there is no abstraction to influence the stack growth direction: We only support a stack that grows from higher addresses towards lower addresses. All supported platforms use this direction.

Method Summary

Modifier and Type	Method and Description
default org.graalvm.word.UnsignedWord	lookupStackBase() The highest address of the stack or zero if not supported.
org.graalvm.word.UnsignedWord	lookupStackEnd() The lowest address of the stack.
default org.graalvm.word.UnsignedWord	lookupStackEnd(org.graalvm.word.UnsignedWord requestedStackSize) The lowest address of the stack.

Method Detail

lookupStackBase

default org.graalvm.word.UnsignedWord lookupStackBase()

The highest address of the stack or zero if not supported.

lookupStackEnd

org.graalvm.word.UnsignedWord lookupStackEnd()

The lowest address of the stack.

lookupStackEnd

default org.graalvm.word.UnsignedWord lookupStackEnd(org.graalvm.word.UnsignedWord requestedStackSize)

The lowest address of the stack. If the OS reserved stack memory is larger than requestedStackSize, then the value for end of the stack memory returned may be before the real stack end.

Parameters:

requestedStackSize - requested stack size. If zero, then the value is ignored.
