/FUNCTIONPADMIN (Create Hotpatchable Image)
Prepares an image for hotpatching.
In order for the linker to produce a hotpatchable image, the .obj files must have been compiled with /hotpatch (Create Hotpatchable Image).
When you compile and link an image with a single invocation of cl.exe, /hotpatch implies /functionpadmin.
