Binary Size Analysis

This repository is used to generate interactive linker statistics and revive the former repo. Please have a look at our interactive example.

Installation

Then clone the tool to a local directory

git clone https://github.com/hegdi/linker_report

This will use GNU nm from your selected toolchain. The toolchain can be selected by setting nm accordingly in config.py. To customise your target further you can change the color mappings in sequences.js.

Running the Analysis

Symbol level analysis - gcc compiler

Now run the ELF linker statistics tool:

# Process Data: provide one or more elf files for analysis
> elfsize.py -i <your file>.elf -b

This will open up a browser page automatically with the visualisation.

Advanced usage

More Options

> elfsize.py -h
usage: elfsize.py [-h] -i [BINARY [BINARY ...]] [-o OUTPUT] [-b]

Analyse binary built by gcc and generate json containing binary size
information

optional arguments:
  -h, --help            show this help message and exit
  -i [BINARY [BINARY ...]], --binary [BINARY [BINARY ...]]
                        path to the binary. You can also specify multiple
                        binaries: -i <path1> <path2>
  -o OUTPUT, --output OUTPUT
                        path of output json, defaults to
                        /Users/leozhou/projects/mbed-os-linker-report/html
                        /data-flare.js, default filename to data-flare.js if a
                        folder is specified
  -b, --browser         launch the pie chart visualisation in a browser
