Struct FunctionInfo 

pub struct FunctionInfo { /* private fields */ }

What emission decided about one function.

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();
let info = e.function(&f)?;
assert_eq!(info.frame().alloc(), 0);

Implementations

impl FunctionInfo

pub fn frame(&self) -> &FrameLayout

The frame as laid out, including any hidden slots edge moves needed (numbered after the function’s own).

Examples

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

let mut f = Function::new("f", &SYSV);
let s = f.stack_slot(SlotKind::Local { size: 8, align: 8 })?;
let b = f.block()?;
f.push(b, op::RET, &[])?;
let info = Emitter::new().function(&f)?;
assert!(info.frame().slot_offset(s).is_some());
