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 +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 can often be useful to write a quick C program with the semantics you're trying to model and see what decisions Clang's IRGen makes about what IR to emit. Studying Clang's CodeGen directory can also be a good source of ideas. Note |
