BTW, for those who want to save an extra second or so in rebuilding hotspot:
make hotspot VM_VERSION_OBJ=xxx
This doesn't rebuild vm_version.o (which is usually built in a separate
pass after all other objects have been built).
There are some caveats. See my comments in JDK-8218577.

Right, exactly. And when you're working on just one file in HotSpot,
this can make a very significant difference to the programmer experience.
