Non-static inline functions are always generated so that they can be
called from other translation units. It's only when a function is both
static and inline that you can (normally) eliminate the function body
altogether.

Yes.

The debugger might still require the function to be in scope (i.e. the
active stack frame must be in the same translation unit) in order to
call it, but that's down to how the debugger resolves symbols which
are entered by the user.

gdb doesn't have this requirement.

Add a minimal main.c so that you can run it as a program.
