Methods

¶InterpStack()

Declared at: clang/lib/AST/Interp/InterpStack.h:24

¶template <typename T>
constexpr size_t aligned_size() const

Description

All stack slots are aligned to the native pointer alignment for storage. The size of an object is rounded up to a pointer alignment multiple.

Declared at: clang/lib/AST/Interp/InterpStack.h:67

Templates

T

¶void clear()

Description

Clears the stack without calling any destructors.

Declared at: clang/lib/AST/Interp/InterpStack.h:62

¶template <typename T>
void discard()

Description

Discards the top value from the stack.

Declared at: clang/lib/AST/Interp/InterpStack.h:44

Templates

T

¶void* grow(size_t Size)

Description

Grows the stack to accommodate a value and returns a pointer to it.

Declared at: clang/lib/AST/Interp/InterpStack.h:73

Parameters

size_t Size

¶void* peek(size_t Size)

Description

Returns a pointer from the top of the stack.

Declared at: clang/lib/AST/Interp/InterpStack.h:75

Parameters

size_t Size

¶template <typename T>
T& peek()

Description

Returns a reference to the value on the top of the stack.

Declared at: clang/lib/AST/Interp/InterpStack.h:51

Templates

T

¶template <typename T>
T pop()

Description

Returns the value from the top of the stack and removes it.

Declared at: clang/lib/AST/Interp/InterpStack.h:35

Templates

T

¶template <typename T, typename... Tys>
void push(Tys&&... Args)

Description

Constructs a value in place on the top of the stack.

Declared at: clang/lib/AST/Interp/InterpStack.h:30

Templates

T

Tys

Parameters

Tys&&... Args

¶void shrink(size_t Size)

Description

Shrinks the stack.

Declared at: clang/lib/AST/Interp/InterpStack.h:77

Parameters

size_t Size

¶size_t size() const

Description

Returns the size of the stack in bytes.

Declared at: clang/lib/AST/Interp/InterpStack.h:59

¶void* top()

Description

Returns a pointer to the top object.

Declared at: clang/lib/AST/Interp/InterpStack.h:56

¶~InterpStack()

Description

Destroys the stack, freeing up storage.

Declared at: clang/lib/AST/Interp/InterpStack.h:27
