This is a cross-check inserter for C programs implemented as a clang compiler plugin.

1. Build libfakechecks (optional, useful for testing):

    $ cd ../../libfakechecks
    $ make all
   

2. Build the clang plugin using the build script:

    $ ../../../scripts/build_cross_checks.py
   

3. To compile code using the plugin, either wrap the compilation command with the cc_wrapper.sh script from this directory:

  $ cc_wrapper.sh <path/to/clang> .../CrossChecks.so <rest of command line...>

or add the following arguments manually to the clang command line, e.g., using CFLAGS:

-Xclang -load -Xclang .../CrossChecks.so -Xclang -add-plugin -Xclang crosschecks

and link against libruntime.a. In both cases, the target binary must then be linked against one of the rb_xcheck implementation libraries: libfakechecks.so or libclevrbuf.so.

This plugin can be tested in this directory by running make test.
