Struct Implicit 

pub struct Implicit {
    pub reg: PReg,
    pub kind: ImplicitKind,
}

An implicit register operand attached to one instruction, beyond those its opcode always has: a call’s argument and return registers, a return’s result registers, a system call’s arguments.

Examples

use backend_lang::mir::{Effects, Function, ImplicitKind, Operand};
use backend_lang::x86_64::{op, SYSV, RAX};

let mut f = Function::new("f", &SYSV);
let b = f.block()?;
let ret = f.push_with(b, op::RET, &[], Effects::new().uses(&[RAX]))?;
assert_eq!(f.implicit(ret)[0].reg, RAX);
assert_eq!(f.implicit(ret)[0].kind, ImplicitKind::Use);

Fields

reg: PReg

The register.

kind: ImplicitKind

Read or written.
