Struct cranelift_codegen::isa::StackRef

pub struct StackRef {
    pub base: StackBase,
    pub offset: StackOffset,
}

A method for referencing a stack slot in the current stack frame.

Stack slots are addressed with a constant offset from a base register. The base can be the stack pointer, the frame pointer, or (in the future) a zone register pointing to an inner zone of a large stack frame.

Fields

base: StackBase

The base register to use for addressing.

offset: StackOffset

Immediate offset from the base register to the first byte of the stack slot.

Implementations

impl StackRef

pub fn masked(
    ss: StackSlot,
    mask: StackBaseMask,
    frame: &StackSlots
) -> Option<Self>

Get a reference to the stack slot ss using one of the base pointers in mask.

pub fn sp(ss: StackSlot, frame: &StackSlots) -> Self

Get a reference to ss using the stack pointer as a base.
