Struct PassStats 

pub struct PassStats { /* private fields */ }

How often one pass ran and how often it changed something.

Examples

use ir_lang::{Linkage, Module, Signature, Type};
use opt_lang::PassKind;

let mut m = Module::new("m");
let f = m.declare_function("f", &Signature::new(&[], &[Type::I32]), Linkage::Export)?;
let mut b = m.build(f)?;
let dead = b.iconst(Type::I32, 1)?;
let live = b.iconst(Type::I32, 2)?;
b.ret(&[live])?;
let stats = opt_lang::optimize(&mut m)?;
let dce = stats.pass(PassKind::Dce);
assert!(dce.runs() >= 1 && dce.changes() >= 1);

Implementations

impl PassStats

pub const fn kind(&self) -> PassKind

The pass.

Examples

use opt_lang::{PassKind, Stats};

assert_eq!(Stats::default().pass(PassKind::Gvn).kind(), PassKind::Gvn);

pub const fn runs(&self) -> u64

How many times it ran (over all functions and iterations).

Examples

use opt_lang::{PassKind, Stats};

assert_eq!(Stats::default().pass(PassKind::Sccp).runs(), 0);

pub const fn changes(&self) -> u64

How many of those runs changed the function.

Examples

use opt_lang::{PassKind, Stats};

assert_eq!(Stats::default().pass(PassKind::Licm).changes(), 0);
