gdbundle-verilator-mem-if

This package implements the gdb_loader method required by gdbundle for loading Python custom commands into GDB.

Your .gdbinit file should be updated with the following:

python
import subprocess, sys
from pathlib import Path

# Execute Python using the user's shell and pull out the sys.path (for site-packages)
paths = subprocess.check_output('python -c "import os,sys;print(os.linesep.join(sys.path).strip())"',shell=True).decode("utf-8").split()

# Extend GDB's Python search path
sys.path.extend(paths)

# Init and load plugins
import gdbundle
gdbundle.init()
end
