class Block

Declaration

class Block { /* full declaration omitted */ };

Description

A memory block, either on the stack or in the heap. The storage described by the block immediately follows it in memory.

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

Member Variables

protected clang::interp::Pointer* Pointers = nullptr

Start of the chain of pointers.

protected llvm::Optional<unsigned int> DeclID

Unique identifier of the declaration.

protected bool IsStatic = false

Flag indicating if the block has static storage duration.

protected bool IsExtern = false

Flag indicating if the block is an extern.

protected bool IsDead = false

Flag indicating if the pointer is dead.

protected clang::interp::Descriptor* Desc

Pointer to the stack slot descriptor.
