XOC provides multi-level IR, it can express and model a program at very high level semantic, whereas gcc/llvm could not. With our experience, keeping all well-tuned transformation and optimization on same IR expression(multi-level) are very important. XOC used to be JavaVM AOT IR, C/C++ compiler IR, JavaScriptVM AOT IR, and it was doing very well. In some new project, XOC even could be used as Deep Learning compiler IR. So XOC is very scalable. In my opinion, perhaps the most interesting feature is its memory description that runs through the framework.
