Struct cranelift_codegen::ir::entities::StackSlot

pub struct StackSlot(_);

[−] Expand description

An opaque reference to a stack slot.

Stack slots represent an address on the call stack.

StackSlots can be created with FunctionBuilder::create_stackslot.

StackSlots are most often used with stack_addr, stack_load, and stack_store.

While the order is stable, it is arbitrary and does not necessarily resemble the stack order.

Implementations

impl StackSlot

pub fn from_u32(x: u32) -> Self[−]

Create a new instance from a u32.

pub fn as_u32(self) -> u32[−]

Return the underlying index value as a u32.

impl StackSlot

pub fn with_number(n: u32) -> Option<Self>[−]

Create a new stack slot reference from its number.

This method is for use by the parser.
