Public Types
using LoadDynamicLibrary
A function that will be called with the name of dll file that must be loaded.
Public Member Functions
ExecutionSession & getExecutionSession () const
ObjectLinkingLayer & getObjectLinkingLayer () const
Error setupJITDylib (JITDylib &JD) override
This method will be called outside the session lock each time a JITDylib is created (unless it is created with EmptyJITDylib set) to allow the Platform to install any JITDylib specific standard symbols (e.g __dso_handle).
Error teardownJITDylib (JITDylib &JD) override
This method will be called outside the session lock each time a JITDylib is removed to allow the Platform to remove any JITDylib-specific data.
Error notifyAdding (ResourceTracker &RT, const MaterializationUnit &MU) override
This method will be called under the ExecutionSession lock each time a MaterializationUnit is added to a JITDylib.
Error notifyRemoving (ResourceTracker &RT) override
This method will be called under the ExecutionSession lock when a ResourceTracker is removed.

static Expected< DenseMap< JITDylib *, SymbolMap > > lookupInitSymbols (ExecutionSession &ES, const DenseMap< JITDylib *, SymbolLookupSet > &InitSyms)
A utility function for looking up initializer symbols.
static void lookupInitSymbolsAsync (unique_function< void(Error)> OnComplete, ExecutionSession &ES, const DenseMap< JITDylib *, SymbolLookupSet > &InitSyms)
Performs an async lookup for the given symbols in each of the given JITDylibs, calling the given handler once all lookups have completed.

Mediates between COFF initialization and ExecutionSession state.

◆ LoadDynamicLibrary

Initial value:

StringRef - Represent a constant reference to a string, i.e.

Represents a JIT'd dynamic library.

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

A function that will be called with the name of dll file that must be loaded.

◆ Create() [1/2]

◆ Create() [2/2]
