I have written a code and used a function for pass manager in llvmlite. I used the following function: def create_pass_manager_builder(opt=3, loop_vectorize=False, slp_vectorize=False): pmb = llvm.create_pass_manager_builder() pmb.opt_level = opt pmb.loop_vectorize = loop_vectorize pmb.populate = populate pmb.add_dead_code_elimination_pass = add_dead_code_elimination_pass pmb.slp_vectorize = slp_vectorize pmb.inlining_threshold = _inlining_threshold(opt) pmb.add_global_dce_pass = add_global_dce_pass pmb.add_global_optimizer_pass = add_global_optimizer_pass pmb.add_ipsccp_pass = add_ipsccp_pass return pmb
I tried to run my module pass manager. However, when i change the level of optimization, I can not see any differences on output of my code in term of optimization. I think there should be a difference between opt-level = 0 and opt-level = 3. does anyone have any idea about that?
