Struct FuncDefBody

pub struct FuncDefBody {
    pub control_regions: EntityDefs<ControlRegion>,
    pub control_nodes: EntityDefs<ControlNode>,
    pub data_insts: EntityDefs<DataInst>,
    pub body: ControlRegion,
    pub unstructured_cfg: Option<ControlFlowGraph>,
}

The body of a Func definition.

Fields

control_regions: EntityDefs<ControlRegion>

control_nodes: EntityDefs<ControlNode>

data_insts: EntityDefs<DataInst>

body: ControlRegion

The ControlRegion representing the whole body of the function.

Function parameters are provided via body.inputs, i.e. they can be only accessed with Value::ControlRegionInputs { region: body, idx }.

When unstructured_cfg is None, this includes the structured return of the function, with body.outputs as the returned values.

unstructured_cfg: Option<ControlFlowGraph>

The unstructured (part of the) control-flow graph of the function.

Only present if structurization wasn’t attempted, or if was only partial (leaving behind a mix of structured and unstructured control-flow).

When present, it starts at body (more specifically, its exit), effectively replacing the structured return body otherwise implies, with body (or rather, its children) always being fully structured.

Implementations

impl FuncDefBody

pub fn at<P: Copy>(&self, position: P) -> FuncAt<'_, P>

Start immutably traversing the function at position.

pub fn at_mut<P: Copy>(&mut self, position: P) -> FuncAtMut<'_, P>

Start mutably traversing the function at position.

pub fn at_body(&self) -> FuncAt<'_, ControlRegion>

Shorthand for func_def_body.at(func_def_body.body).

pub fn at_mut_body(&mut self) -> FuncAtMut<'_, ControlRegion>

Shorthand for func_def_body.at_mut(func_def_body.body).
