APValue - This class implements a discriminated union of [uninitialized] [APSInt] [APFloat],...

Decl - This represents one declaration (or definition), e.g.

This represents one expression.

A (possibly-)qualified type.

Holds all information required to evaluate constexpr code in a module.

An emitter which evaluates opcodes as they are emitted.

Defines the result of an evaluation.

std::optional< APValue > toRValue() const

If the result is an LValue, convert that to an RValue and return it.

APValue toAPValue() const

Returns an APValue for the evaluation result.

QualType getSourceType() const

bool checkReturnValue(InterpState &S, const Context &Ctx, const Pointer &Ptr, const SourceInfo &Info)

Check that none of the blocks the given pointer (transitively) points to are dynamically allocated.

llvm::PointerUnion< const Decl *, const Expr * > DeclTy

bool checkFullyInitialized(InterpState &S, const Pointer &Ptr) const

Check that all subobjects of the given pointer have been initialized.

EvaluationResult(const Context *Ctx)

void dump() const

Dump to stderr.

A pointer to a memory block, live or dead.

Describes the statement/declaration an opcode was generated from.

llvm::PointerUnion< const Decl *, const Expr * > DeclTy

The JSON file list parser is used to communicate input to InstallAPI.
