Struct EmittedFunction 

pub struct EmittedFunction { /* private fields */ }

One emitted function: its place in the code, its frame, and its call-site records.

Examples

use backend_lang::mir::Function;
use backend_lang::x86_64::{op, Emitter, SYSV};

let mut f = Function::new("f", &SYSV);
let b = f.block()?;
f.push(b, op::RET, &[])?;
let mut e = Emitter::new();
e.function(&f)?;
let p = e.finish()?;
let ef = &p.functions()[0];
assert_eq!((ef.name(), ef.offset(), ef.size()), ("f", 0, 6));

Implementations

impl EmittedFunction

pub fn name(&self) -> &str

The function’s name.

Examples

See EmittedFunction.

pub fn offset(&self) -> usize

The offset of its first byte.

Examples

See EmittedFunction.

pub fn size(&self) -> usize

Its size in bytes, jump tables included.

Examples

See EmittedFunction.

pub fn frame(&self) -> &FrameLayout

Its frame. With the stack pointer fixed in the body, the canonical frame address is the body’s stack pointer plus cfa_offset, which is all a stack walker needs to step from a call site to its caller.

Examples

See EmittedFunction.

pub fn call_sites(&self) -> &[CallSiteRecord]

Its call-site records, in code order.

Examples

See CallSiteRecord.
