How to test a compiler using a variety of open source code available on the Internet

This presentation describes results of a pilot project set up by QA team responsible for the process of Intel Compiler testing. The idea is the following – try download source code files written in C/C++ and to compile them using Intel Compiler. To distinguish bad source code from valid source code, it’s suggested to compile each source file twice: with Intel Compiler and with GCC compiler. When we process just several dozens of open source files we don’t face a lot of bugs, but when we compile a million of files, a number of bugs increases.
