AnonymousPointerCreator

Initial value:

Represents an object file section.

unique_function is a type-erasing functor similar to std::function.

Creates a new pointer block in the given section and returns an Anonymous symbol pointing to it.

The pointer block will have the following default values: alignment: PointerSize alignment-offset: 0 address: highest allowable

Definition at line 2015 of file JITLink.h.

AsyncLookupResult

Initial value:

A map of symbol names to resolved addresses.

Definition at line 1901 of file JITLink.h.

Enumerator
Strong
Weak

Definition at line 396 of file JITLink.h.

Scope

Defines the scope in which this symbol should be visible: Default – Visible in the public interface of the linkage unit.

Hidden – Visible within the linkage unit, but not exported from it. SideEffectsOnly – Like hidden, but symbol can only be looked up once to trigger materialization of the containing graph. Local – Visible only within the LinkGraph.
