Practical fuzzing for C/C++ compilers
Speaker: Oliver Stannard
------
-----
In this talk, I will give an overview of the fuzzers which I use to test Clang and GCC. These include open-source fuzzers like csmith, as well as some custom code-generators I have written to target specific parts of the compiler.
I'll also talk about how I run these fuzzers, testing a large number of compiler options. In particular, I have found this to be very useful for finding bugs caused by the interaction of seemingly unrelated compiler features.
Finally, I'll talk about some useful techniques for turning fuzzer failures into good bug reports, and how to continue running fuzzers before the bugs they find have been fixed.
