Hi everybody, I have a question about reduccing test : - I found a program on the net, and tried to built it. But I find something wrong in one file : when I built it with g++ -g -O0 the binary is about 1,2M. when I built it with g++ -g -Os the binary is about 33M. about 25M for O1 O2, O3 when I built it with clang++, the size is always about 1,4M without debug option, the file has about the same size with any optimization flags I tried to remove a few small functions, or pieces of code, but most of the time, the code size moves for +/- 1 to 4M. I don't know how do reduce the case, because the result is unpredictable, and it takes 20s to compile with 01, the fastest. So, if you could give me some advices. P.S: I have gcc 4.4.5 Regards
