SYNOPSIS

bloat-blame [options] binary

DESCRIPTION

bloat-blame is a tool for working out how many bytes each line of source code takes up in a C++ program. It uses addr2line and readelf to parse debug info.

OPTIONS

• --extent [all|.text]: Specifies which bytes within the binary should be analysed

DEPENDENCIES

bloat-blame depends on:

• Python
• addr2line - a part of GNU binutils
• objdump - also a part of GNU binutils

HOWTO

1. Build your program/library with debug info turned on:

    $ CFLAGS='-g' make
   

2. Run bloat-blame on the resulting binary:

    $ bloat-blame ./myprog
   

bloat-blame will output something like:

22     src/main.c:22
213    src/main.c:23
7653   src/bloat.c:324

This is a list in ascending order of size. The first column is the number of bytes apportioned to the file/line in the second column.
