protected ABIDescriptor
abiDescriptor()

Implements abstract jdk.internal.foreign.abi.aarch64.CallArranger.abiDescriptor.

protected TypeClass
getArgumentClassForBindings(MemoryLayout layout, boolean forVariadicFunction)

Overrides jdk.internal.foreign.abi.aarch64.CallArranger.getArgumentClassForBindings.

protected boolean
requiresSubSlotStackPacking()

Implements abstract jdk.internal.foreign.abi.aarch64.CallArranger.requiresSubSlotStackPacking.

Returns true if this ABI requires sub-slot (smaller than STACK_SLOT_SIZE) packing of arguments on the stack.
protected boolean
spillsVariadicStructsPartially()

Implements abstract jdk.internal.foreign.abi.aarch64.CallArranger.spillsVariadicStructsPartially.

Should some fields of structs that assigned to registers be passed in registers when there are not enough registers for all the fields of the struct?
protected boolean
useIntRegsForVariadicFloatingPointArgs()

Implements abstract jdk.internal.foreign.abi.aarch64.CallArranger.useIntRegsForVariadicFloatingPointArgs.

Are floating point arguments to variadic functions passed in general purpose registers instead of floating point registers?
protected boolean
varArgsOnStack()

Implements abstract jdk.internal.foreign.abi.aarch64.CallArranger.varArgsOnStack.

Are variadic arguments assigned to registers as in the standard calling convention, or always passed on the stack?
