This documents the support for computing, storing, and restoring call graphs with LLVM. This adds the options and the design documentation for computing and storing the call graphs. To enable, use `-fcall-graph-section`. Inferring indirect call targets from a binary is challenging without source-level information. Hence, the reconstruction of a fine-grained call graph from the binary is unfeasible for indirect/virtual calls. To address this, designed solution is to collect the necessary information to construct the call graph while the source information is present, and store it in a non-code section of the binary.
