dwarfy

Let's evaluate debugging user experience. The tool automates the process of putting breakpoints and evaluating the quality of backtraces. At the moment, it supports only GDB, but I will add support for LLDB as well.

Examples

Process all functions of the program

dwarfy-bt -count-entry-vals ./a.out
== dwarfy ==
version 1.0


Do you want to specify functions for breakpoints? (y/n) n
Are you sure you want to go through to all functions of the program? (y/n) y
Please wait...

Processing backtraces...

====================================
Num of backtraces proccessed 2
<optimized out> parameters 16.67%
@entry values 0.0%
====================================

Process just a function

dwarfy-bt -count-entry-vals ./a.out
== dwarfy ==
version 1.0


Do you want to specify functions for breakpoints? (y/n) y
Please specify function to set breakpoint on it:
fn2
More functions? (y/n) n
Processing backtraces...

====================================
Num of backtraces proccessed 1
<optimized out> parameters 33.33%
@entry values 0.0%
====================================

Process core-files

dwarfy-bt -process-core-files /home/testing/ /home/testing/a.out
== dwarfy ==
version 1.0
====================================
Num of backtraces proccessed 1
<optimized out> parameters 0.0%
====================================
