Detailed Description
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.

◆ notifyAdding()
|
pure virtual |
This method will be called under the ExecutionSession lock each time a MaterializationUnit is added to a JITDylib.
Implemented in llvm::orc::ELFNixPlatform, llvm::orc::MachOPlatform, and llvm::orc::COFFPlatform.
◆ notifyRemoving()
|
pure virtual |
This method will be called under the ExecutionSession lock when a ResourceTracker is removed.
Implemented in llvm::orc::ELFNixPlatform, llvm::orc::MachOPlatform, and llvm::orc::COFFPlatform.
◆ setupJITDylib()
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).
Implemented in llvm::orc::ELFNixPlatform, llvm::orc::MachOPlatform, and llvm::orc::COFFPlatform.
◆ teardownJITDylib()
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.
Implemented in llvm::orc::ELFNixPlatform, llvm::orc::MachOPlatform, and llvm::orc::COFFPlatform.
