A tool to visualize call graphs

vrc

vrc is a tool to read the call graph from GCC RTL dumps. It is inspired by the egypt tool ("egypt" is rot13 for "rtlcg" aka RTL call graph), with a lot of new functionality:

• interactive mode with readline + completion

• query call graph in addition to generating DOT file

• consult compile_commands.json to find/build dumps automatically

• virtual (manually created) nodes and edges

The name is unfortunately not rot13 anymore. It stands for "visit RTL callgraph".

Installation

pip install --user . will install an executable called vrc.

Usage

Run it in a directory that has a compile_commands.json file.

Documentation coming soon. For now, the help command and TAB completion are your friends.
