Struct RegInfo 

pub struct RegInfo { /* private fields */ }

One physical register: its name, its class, and its hardware number.

Examples

use backend_lang::x86_64::{self, GPR, R12};

let r12 = x86_64::TARGET.reg(R12);
assert_eq!(r12.name(), "r12");
assert_eq!(r12.class(), GPR);
assert_eq!(r12.hw(), 12);

Implementations

impl RegInfo

pub const fn new(name: &'static str, class: RegClass, hw: u8) -> RegInfo

Describes a register named name in class, encoded as hw (the number the ISA’s instruction fields carry).

Examples

use backend_lang::RegClass;
use backend_lang::target::RegInfo;

let r = RegInfo::new("r0", RegClass::new(0), 0);
assert_eq!(r.name(), "r0");

pub const fn name(&self) -> &'static str

The register’s assembly name.

Examples

use backend_lang::x86_64::{self, XMM3};

assert_eq!(x86_64::TARGET.reg(XMM3).name(), "xmm3");

pub const fn class(&self) -> RegClass

The register’s class.

Examples

use backend_lang::x86_64::{self, VEC, XMM3};

assert_eq!(x86_64::TARGET.reg(XMM3).class(), VEC);

pub const fn hw(&self) -> u8

The register’s hardware number.

Examples

use backend_lang::x86_64::{self, RSP};

assert_eq!(x86_64::TARGET.reg(RSP).hw(), 4);
