Cold spots are those parts of code that are rarely used (or executed); and the Hot spots are those parts of the code, that are very frequently used. Doing this analysis in the development stage, helps: (i) improving the performance of the application by tuning the hot spots, and (ii) removing the dead code and/or rewriting or moving the cold spots, in such a way that the code will be executed for decent number of...

Sun Studio C/C++: Profile Feedback Optimization II

Most of the related information is already available at: Sun Studio C/C++: Profile Feedback Optimization. This blog post tries to cover the missing {from previous blog post} pieces of PFO (aka Feedback Based Optimization, FBO).Compiling with multiple profilesEven though it was not mentioned explicitly {in plain english} in the C++ compiler options, Sun C/C++ compilers accept multiple profiles on the compile line, with multiple -xprofile=use:<dir> options. -xprofile=use:<dir>:<dir>..<dir> results in a compilation error.eg.,CC...
