This patch adds CaGe, the call graph generator plugin for LLVM developed by @TimHeldmann.
This version is slightly modified from the original project to fit in with the rest of the MetaCG project.
So far, this patch only contains functionality to register the pass and build the call graph.
It does not include any call graph embedding functionality or runtime library for now.
To make this project easily extendable for different use cases, the pass can register different
CallGraphConsumers.At the moment, the only available consumer is the
FileExporter, which writes the call graph to a file.I adopted the integration tests from CGC2, removing those that are either incompatible or irrelevant.
Tests can be run by executing
./runCaGeTests.shin<build_dir>/tools/cage/test/.
