generated code.
Beyond the specific items on the list below, it's worth noting that the most
mature frontend for LLVM is Clang. As a result, the further your IR gets from what Clang might emit, the less likely it is to be effectively optimized. It

Studying Clang's CodeGen directory can also be a good source of ideas. Note
