I am looking for ideas. I have a C++ program that I would like to optimize. I have tried -O3 and some other options and -O2 actually does better than -O3
Anyone have any suggestions for combinations of options that might improve over -O2 -fomit-frame-pointer -fexpensive-optimizations did not help, actually made it worse. Does making a cpu specific executable (-march=i686 ) make any differenence? The program I am looking at is related to chessbench and I was told it is almost twice as fast in windows as linux. I don't see anything obvious (and have not tested a windows version myself, no windows compiling for me!). Best regards. Tony Preston Cancer is Curable, Ask me why!
