; All of these globals should pass through uninstrumented because of their
; custom section name. The .CRT section is the standard way to register custom
; initializers, and the ATL uses the ATL section to register other stuff.
; Either way, if the section has a '$' character, it is probably participating
; in section sorting, and we should probably not put a redzone around it.
