Comparing Build Sizes {#comparing-build-sizes}
=====================
There is a make target for build size comparison. You can use it like that:
~~~~~~~~~~~~~~~~~~~
$ cd RIOT/test/test_something
$ git checkout master
$ BINDIRBASE=master-bin make buildtest
$ git checkout my-branch
$ BINDIRBASE=my-branch-bin make buildtest
$ OLDBIN=master-bin NEWBIN=my-branch-bin make info-buildsizes-diff
text data bss dec BOARD/BINDIRBASE
0 0 0 0 avsextrem **← this line contains the diff**
57356 1532 96769 155657 master-bin
57356 1532 96769 155657 my-branch-bin
...
~~~~~~~~~~~~~~~~~~~
Check it out, the output contains colors. ;)
