Introduction

A tool to map binary trace to source code with help of objdump and Emacs.

Compile

    cd src
    make

Emacs Configuration

Put 'tracemapping.el' to your Emacs plugin directory, such as ~/.emacs.d. Then put the following code in your .emacs, init.el, site-load.el, or other relevant file

(add-to-list 'load-path "path-to-tracemapping.el")
(require 'tracemapping)

Source File Generation

    objdump -dl vmlinux > example.dl
    ./sourceline example.dl > example.sourceline

Generate tracemap

'example.trace' is a binary trace file you got from qemu or other dynamic program analysis tools.

    ./tracemap example.sourceline example.trace > example.tracemap

Generate Function Index From tracemap File

    ./get-fun.py example.tracemap > example.fun

Usage

Open example.tracemap with Emacs, "Ctrl+z" to jump to source code, you may need to select your source code directory first.

Open example.fun with Emacs, click to jump to source code or tracemap file.
