Struct gf::pivot::fragment::FragmentCfg

pub struct FragmentCfg<'a, D: Direction> { /* fields omitted */ }

🟢 Control flow graph of a sealed fragment.

Forward CFGs are prebuilt for all sealed fragments, and can be retrieved via Fragment::cfg.

Implementations

impl<'a, D: Direction> FragmentCfg<'a, D>

pub unsafe fn from_unsealed(
    fragment: Fragment<'a>,
    unsealed: &'a UnsealedFragmentCfg<D>
) -> Self

Wrap an unsealed fragment CFG.

pub fn fragment(&self) -> Fragment<'a>

Return parent fragment.

pub fn entry(&self) -> BasicBlock<'a>

Return the entry basic block wrt to CFG direction.

pub fn exit(&self) -> BasicBlock<'a>

Return the exit basic block wrt to CFG direction.

pub fn pred(
    &self,
    basic_block: BasicBlock<'a>
) -> impl Iterator<Item = Edge<'a>> + '_

Return an iterator over predecessor edges of a basic block wrt to CFG direction.

Errors

• Panics if the basic block does not belong to this CFG.

pub fn succ(
    &self,
    basic_block: BasicBlock<'a>
) -> impl Iterator<Item = Edge<'a>> + '_

Return an iterator over successor edges of a basic block wrt to CFG direction.

Errors

• Panics if the basic block does not belong to this CFG.

pub fn preorder(&self) -> impl Iterator<Item = BasicBlock<'a>> + '_

Return a preorder iterator over basic blocks.

pub fn reverse_preorder(&self) -> impl Iterator<Item = BasicBlock<'a>> + '_

Return a reverse preorder iterator over basic blocks.

pub fn postorder(&self) -> impl Iterator<Item = BasicBlock<'a>> + '_

Return a postorder iterator over basic blocks.

pub fn reverse_postorder(&self) -> impl Iterator<Item = BasicBlock<'a>> + '_

Return a reverse postorder iterator over basic blocks.

Trait Implementations

impl<'a, D: Clone + Direction> Clone for FragmentCfg<'a, D>

fn clone(&self) -> FragmentCfg<'a, D>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
