1. Disable or uninstall the official C/C++ plugin.
2. Install the clangd plugin.
3. Build the kernel with clang:

/path/to/kernel_source$ make CC=clang defconfig
/path/to/kernel_source$ make CC=clang -j16

4. Generate the compile_commands.json:

/path/to/kernel_source$ python ./scripts/clang-tools/gen_compile_commands.py

# Requirements:
#   clang - The classes/structs you want to dump must be used in code at least once, not just defined.
#   MSVC  - The classes/structs you want to dump must have "MEOW" in the name for "reportSingleClass" to work.
# Usage:
#   $ make dump_vtables file=test.cpp
dump_vtables:
  clang -cc1 -fdump-record-layouts -emit-llvm  $(file) > clang-vtable-layout-$(file).txt
  clang -cc1 -fdump-vtable-layouts -emit-llvm  $(file) > clang-record-layout-$(file).txt
  g++ -fdump-lang-class=$(file).txt $(file)
  cl.exe $(file) /d1reportSingleClassLayoutMEOW > msvc-single-class-vtable-layout-$(file).txt

This is a technique for extracting all imported modules from a packaged Python application as .pyc files, then decompiling them. The target program needs to be run from scratch, but no debugging symbols are necessary (assuming an unmodified build of Python is being used).

This was originally performed on 64-bit Linux with a Python 3.6 target. The Python scripts have since been updated to handle pyc files for Python 2.7 - 3.9.

Theory

In Python we can leverage the fact that any module import involving a .py* file will eventually arrive as ready-to-execute Python code object at this function:

PyObject* PyEval_EvalCode(PyObject *co, PyObject *globals, PyObject *locals);

Architecture calling conventions

Every architecture has its own way of invoking and passing arguments to the kernel. The details for various architectures are listed in the two tables below.

The first table lists the instruction used to transition to kernel mode, (which might not be the fastest or best way to transition to
