Just posting a tip that I found. If you are like me and hate combing through a map file just for a quick look at a project's codesize, then luckily there is a nice utility built into Kinetis Design Studio from the GCC Toolchain. I noticed that the switch to turn this on is in a different place than it was in CodeWarrior.
Go to Project…Properties…C/C++ Build…Settings…
On the Toolchains tab check Print size
Now you will see code size information in the Console window when you build the entire project.
