Hi All,

The initializer patch review at https://reviews.llvm.org/D74300 has been
updated. The new version contains a MachOPlatform implementation that
demonstrates how Platforms and ObjectLinkingLayer::Plugins can work
together to implement platform specific initialization. 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 code with the
Objective-C runtime. This allows LLJIT instances (and the lli command line
tool) to run IR compiled from Objective-C and Swift sources.

Discussion on the review is ongoing (thanks especially to Stefan Granitz
for his review comments!) but I will aim to have the patch tidied up and
landed in the coming week.
