This new system is flexible enough to permit two very different platform implementations for LLJIT that are already available in tree: GenericLLVMIRPlatform and MachOPlatform. The former essentially re-implements the existing llvm.global_ctor scanning scheme: It promotes functions that appear in the llvm.global_ctors array, then looks them up by name and executes them when requested. On the other hand, MachOPlatform implements a scheme that mimics the behavior of the Da...

In this case, the MachOPlatform installs a plugin that scans objects for __objc_classlist and __objc_selref sections and uses them to register JIT'd co...
