Hi Nikita, Glad to hear that Rust code can benefit a lot from this. I have put patches to enable merge-similar functions with thinLTO. https://reviews.llvm.org/D52896 etc. <https://reviews.llvm.org/D52896> This is more powerful than existing merge-functions pass and all we need to do is port these patches to trunk llvm.

Hi, I'm interested in finding ways to reduce code size. LLVM's MergeFunctions pass seems like a promising option, and I'm curious about its status in tree. Enabling MergeFunctions gives a 1% code size reduction across the entire iOS shared cache (a collection of a few hundred system-critical DSO's). The numbers are even more compelling for Swift code. In fact, the swift compiler

Hi Vishal, Ruijie, Thanks for your interest in the project. To get started, the first task would be to merge the 5 patches on top of trunk llvm. The list of patches are listed in the project description: http://llvm.org/OpenProjects.html#llvm_mergesim Please create an account in llvm phabricator (reviews.llvm.org) if you haven't already, and put your patches there. Let me know if you have
