Bare Metal Kinetis Startup in CW10.1

I have a Kinetis K40 Tower Kit which I'm programming with CW10.1.

 

When I create a new project without Device Initialization or Project Expert, and I go to the Project Properties, I can see that the Entry Point is __thumb_startup.

 

My question is...  Where is __thumb_startup?

 

kinetis_sysinit.c shows the prototype and I see it in the vector table, but I don't see the actual function. Oddly though, the code compiles and runs just fine starting at the first line in main().
