LLVM: llvm::orc::Platform Class Reference (original) (raw)
Platforms set up standard symbols and mediate interactions between dynamic initializers (e.g. More...

| Public Member Functions | |
|---|---|
| virtual | ~Platform () |
| virtual Error | setupJITDylib (JITDylib &JD)=0 |
| 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). | |
| virtual Error | teardownJITDylib (JITDylib &JD)=0 |
| 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. | |
| virtual Error | notifyAdding (ResourceTracker &RT, const MaterializationUnit &MU)=0 |
| This method will be called under the ExecutionSession lock each time a MaterializationUnit is added to a JITDylib. | |
| virtual Error | notifyRemoving (ResourceTracker &RT)=0 |
| This method will be called under the ExecutionSession lock when a ResourceTracker is removed. |
Platforms set up standard symbols and mediate interactions between dynamic initializers (e.g.
C++ static constructors) and ExecutionSession state. Note that Platforms do not automatically run initializers: clients are still responsible for doing this.

◆ lookupInitSymbols()
A utility function for looking up initializer symbols.
Performs a blocking lookup for the given symbols in each of the given JITDylibs.
Note: This function is deprecated and will be removed in the near future.

◆ lookupInitSymbolsAsync()
Performs an async lookup for the given symbols in each of the given JITDylibs, calling the given handler once all lookups have completed.
