pub struct InstLayout { /* fields omitted */ }

Determines the order of instructions.

Methods

impl InstLayout

pub fn new() -> Self

Create a new instruction layout.

pub fn is_inst_inserted(&self, inst: Inst) -> bool

Check whether an instruction has been placed in the layout.

pub fn append_inst(&mut self, inst: Inst)

Append an instruction to the end of the function.

pub fn prepend_inst(&mut self, inst: Inst)

Prepend an instruction to the beginning of the function.

pub fn insert_inst_after(&mut self, inst: Inst, after: Inst)

Insert an instruction after another instruction.

pub fn insert_inst_before(&mut self, inst: Inst, before: Inst)

Insert an instruction before another instruction.

pub fn remove_inst(&mut self, inst: Inst)

Remove an instruction from the function.

pub fn insts<'a>(&'a self) -> impl Iterator<Item = Inst> + 'a

Return an iterator over all instructions in layout order.

pub fn first_inst(&self) -> Option<Inst>

Get the first instruction in the layout.

pub fn last_inst(&self) -> Option<Inst>

Get the last instruction in the layout.

pub fn prev_inst(&self, inst: Inst) -> Option<Inst>

Get the instruction preceding inst in the layout.

pub fn next_inst(&self, inst: Inst) -> Option<Inst>

Get the instruction following inst in the layout.
