Enum Location 

#[non_exhaustive]
pub enum Location {
    None,
    Reg(PReg),
    Slot(StackSlot),
}

Where a virtual register lives for its whole life after allocation.

Examples

use backend_lang::regalloc::Location;
use backend_lang::x86_64::RAX;

assert_eq!(Location::Reg(RAX), Location::Reg(RAX));

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

None

Not live anywhere reachable (never used, or only in dead code).

Reg(PReg)

A physical register.

Slot(StackSlot)

A stack slot (a spilled block parameter).
