Hello All, When I started using gcc-4.8.1 I was glad to observe a substantial speed-up of about 10% in my code, as compared with gcc-4.7.3.
Usually, switching to newer compilers has a relatively minor effect and definitely not a 10% speed-up. Was there anything significant in gcc-4.8.1 which may explain this dramatic improvement? My code is C++98 which is compiled with profile-driven optimizations, with -O2. My target is generic 32 bit Intel architecture. The result is run on Intel Xeon. The application is CPU intensive. Michael
