EquivalentAtoms

llvm::SmallVector<llvm::SmallVector<Atom> > clang::dataflow::SimplifyConstraintsInfo::EquivalentAtoms

List of equivalence classes of atoms.

For each equivalence class, the original constraints imply that all atoms in it must be equivalent. Simplification replaces all occurrences of atoms in an equivalence class with a single representative atom from the class. Does not contain equivalence classes with just one member or atoms contained in TrueAtoms or FalseAtoms.

FalseAtoms

llvm::SmallVector<Atom> clang::dataflow::SimplifyConstraintsInfo::FalseAtoms

Atoms that the original constraints imply must be false.

Simplification replaces all occurrences of these atoms by a false literal (which may enable additional simplifications).

TrueAtoms

llvm::SmallVector<Atom> clang::dataflow::SimplifyConstraintsInfo::TrueAtoms

Atoms that the original constraints imply must be true.

Simplification replaces all occurrences of these atoms by a true literal (which may enable additional simplifications).
