[cfe-dev] clang-tidy / static analysis

[Jonas Toth via cfe-dev]

Hi,

clang-tidy seems to be the correct point to start. It is made to rewrite
source code and is easy to begin with.

Take a look into the clang-tools-extra repository and browse the code,
there are a lot of examples. There is a dedicated tutorial in the docs
to get started as well.
