Who Called Me?

A basic tool for showing the callgraph to one function for c code projects.

Usage

1. Add the flag -fdump-rtl-expand to the GCC command line wich emits RTL files ending in .expand

2. Add the .expand file data to a database

   wcm_create_db.py database.db folder1/*.expand folder2/*.expand...

3. Query the database by running wcm.py. The is using fzf to be able to do "fuzzy finding" of the variable
