ChangeStatus&
operator&=(
    ChangeStatus& l,
    ChangeStatus r);

Intersect LHS with *RHS in place.

template<unsigned int ElementSize>
bool
operator&=(
    SparseBitVector<ElementSize>& LHS,
    SparseBitVector<ElementSize> const* RHS);

Return Value

  • Whether the state or IR changed.

  • True if any bit in LHS changed.

  • True if any bit in *LHS changed.
