Implementations

impl Imm

pub fn new(data: u32, width: u32) -> Imm

Generates an immediate from data + width

pub fn no_extend_u32(&self) -> u32

Return the immediate data as a u32

use rsim::processor::decode::Imm;
let i = Imm::new(0xF0FF, 16);
assert_eq!(i.no_extend_u32(), 0xF0FF);

pub fn no_extend_u64(&self) -> u64

Return the immediate data as a u64

use rsim::processor::decode::Imm;
let i = Imm::new(0xF0FF, 16);
assert_eq!(i.no_extend_u64(), 0xF0FF);

pub fn sign_extend_u32(&self) -> u32

Sign-extend the immediate value and return as a u32

use rsim::processor::decode::Imm;
let i = Imm::new(0xF0FF, 16);
assert_eq!(i.sign_extend_u32(), 0xFFFF_F0FF);
assert_eq!(Imm::new(0x00FF_0000, 32).sign_extend_u32(), 0x00FF_0000);

pub fn sign_extend_u64(&self) -> u64

Sign-extend the immediate value and return as a u64

use rsim::processor::decode::Imm;
let i = Imm::new(0xF0FF, 16);
assert_eq!(i.sign_extend_u64(), 0xFFFF_FFFF_FFFF_F0FF);

pub fn sign_extend_i32(&self) -> i32

Sign-extend the immediate value and return as a i32

use rsim::processor::decode::Imm;
let i = Imm::new(0xFFFF, 16);
assert_eq!(i.sign_extend_i32(), -1);

pub fn sign_extend_i64(&self) -> i64

Sign-extend the immediate value and return as a i64

use rsim::processor::decode::Imm;
let i = Imm::new(0xFFFF, 16);
assert_eq!(i.sign_extend_i64(), -1);
