...course, we can target the same program to ARM or X86 for performance comparison. The questions is: We have to recognize the patterns for modular arithmetic from optimized IR and translate into corresponding instructions. After investigation, I think LLVM can not do a good job on such a simple but unordinary instruction set. Is it possible that the patterns still recognizable after optimization? On the whole, is this viable using LLVM or is it better to write a compiler for this particular DSL from scratch?
