   The doc is being written. Until it is ready, I think it might be helpful to build a testcase such as xgen/test/compile/void.c, and debug the xocc.exe to see how it generate IR and lowest IR (wasm) from C-language AST tree.

   Good question! In a simply word, GCC&LLVM compilers are good at traditional RISC-like hardware, namely, IR expected to be load/store/compute/branch, etc. More important is, these compilers do not allow user to add custom

   Sure, not only Alibaba, there are lots of applications of XOC. XOC has been used in Java AOT compiler, JavaScript AOT compiler and Type Inference Engine, VLIW/DSP compiler, etc. And XOC is also used in some teaching. For now, XOC is us

   Thanks for your attention! XOC infrastructure has been widely used in many field. Recently, some famous AI chip design manufacturers has implemented DSL compiler of AI chip based on XOC. We hope the AI compiler will be open source soon.

    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
