Hi, I am trying to tune flags for SPEC2006's libquantum. I am looking for a set of flags that I can use to start with. I found this thread: http://lists.cs.uiuc.edu/pipermail/llvmdev/2014-January/069430.html Are there flags other than: -mllvm -vectorize-num-stores-pred=1 -mllvm enable-loadstore-runtime-unroll -mllvm -enable-ind-var-reg-heur I think I need to use -O3 -flto -emit-llvm with the compile command and -flto -O3 at linking, to enable LTO. Appreciate pointers on other SPEC INT programs Best, Ramshankar -------------- next part -------------- An HTML attachment was scrubbed...
