  Program (Context &Ctx)     ~Program ()   unsigned  getOrCreateNativePointer (const void *Ptr)   Marshals a native pointer to an ID for embedding in bytecode.
  const void *  getNativePointer (unsigned Idx)   Returns the value of a marshalled native pointer.
  unsigned  createGlobalString (const StringLiteral *S, const Expr *Base=nullptr)   Emits a string literal among global data.
  Pointer  getPtrGlobal (unsigned Idx) const   Returns a pointer to a global.
  Block *  getGlobal (unsigned Idx)   Returns the value of a global.
  std::optional< unsigned >  getGlobal (const ValueDecl *VD)   Finds a global's index.
  std::optional< unsigned >  getGlobal (const Expr *E)   std::optional< unsigned >  getOrCreateGlobal (const ValueDecl *VD, const Expr *Init=nullptr)   Returns or creates a global an creates an index to it.
  unsigned  getOrCreateDummy (const DeclTy &D)   Returns or creates a dummy value for unknown declarations.
  std::optional< unsigned >  createGlobal (const ValueDecl *VD, const Expr *Init)   Creates a global and returns its index.
  std::optional< unsigned >  createGlobal (const Expr *E)   Creates a global from a lifetime-extended temporary.
  template<typename... Ts> Function *  createFunction (const FunctionDecl *Def, Ts &&...Args)   Creates a new function from a code range.
  template<typename... Ts> Function *  createFunction (Ts &&...Args)   Creates an anonymous function.
  Function *  getFunction (const FunctionDecl *F)   Returns a function.
  Record *  getOrCreateRecord (const RecordDecl *RD)   Returns a record or creates one if it does not exist.
  Descriptor *  createDescriptor (const DeclTy &D, PrimType Type, Descriptor::MetadataSize MDSize=std::nullopt, bool IsConst=false, bool IsTemporary=false, bool IsMutable=false)   Creates a descriptor for a primitive type.
  Descriptor *  createDescriptor (const DeclTy &D, const Type *Ty, Descriptor::MetadataSize MDSize=std::nullopt, bool IsConst=false, bool IsTemporary=false, bool IsMutable=false, const Expr *Init=nullptr)   Creates a descriptor for a composite type.
