Build Interceptor captures the .i files of any project while it is built from source using the gcc toolchain. Anyone who has tried this on a large scale will find out that it is non-trivial to build a project from source and obtain the .i files generated during the build process. Step-by-step instructions are given on how to use the provided scripts to do this without any modification to the build process of the project you are trying to capture. These scripts were used to capture the build process of 92.5% of the projects in the Red Hat Linux 7.3 distribution.
Oink is a collaboration of backends for the Elsa C and C++ frontend. It aims to be industrial-strength for immediate utility in finding bugs, extensible for ease in adding backends, and composable for ease in combining existing ones. It computes expression-level and type-level data flow, and statement-level intra-procedural control flow (by delegating to Elsa). It's easy to get started by using the two demo backends that print graphs of these flows. It also comes with a client of the data flow analysis that does type qualifier inference: Cqual++, a C/C++ frontend for Cqual. Whole-program analyses may be attempted using the linker imitator.
