Detailed Description

A pointer to a memory block, live or dead.

This object can be allocated into interpreter stack frames. If pointing to a live block, it is a link in the chain of pointers pointing to the block.

In the simplest form, a Pointer has a Block* (the pointee) and both Base and Offset are 0, which means it will point to raw data.

The Base field is used to access metadata about the data. For primitive arrays, the Base is followed by an InitMap. In a variety of cases, the Base is preceded by an InlineDescriptor, which is used to track the initialization state, among other things.

The Offset field is used to access the actual data. In other words, the data the pointer decribes can be found at Pointee->rawData() + Pointer.Offset.

/// Pointee                      Offset
/// │                              │

Compute an integer that can be used to compare this pointer to another one.

Compute an offset that can be used to compare the pointer to another one with the same base.

This is usually NOT the same as the pointer offset regarding the AST record layout.

To get accurate results, we basically have to compute the lvalue offset using the ASTRecordLayout.

FIXME: We're still mixing values from the record layout with our internal offsets, which will inevitably lead to cryptic errors.

startLifetime()

void Pointer::startLifetime

Start the lifetime of this pointer.

This works for pointer with an InlineDescriptor as well as primitive array elements. Pointers are usually alive by default, unless the underlying object has been allocated with std::allocator. This function is used by std::construct_at.
