Hi,

I am interested in this as well and I am confused by what you are
saying. Even if a compilation database is used with cmake for example,
you still need to perform the analysis on the file in the compilation
database. What am I missing here? Is there a tool besides scan-build
that reads the compilation database and performs the analysis? I know of
https://github.com/rizsotto/scan-build but this is not even part of the
LLVM project so I assume there's something else you know about.
