how to pass params to inline functions by reference or value?

Is the context C++ or C?

For C++, that [#1] is incorrect for non-regular types, and likely incorrect
for regular types.  (But for C++ you probably should use a const& for the
inline function's parm, which would do what you want.)

For C, I'm not sure, but I suspect that [#1] is incorrect.

What happens when you test compile the two variants with --save-temps and
-O2, and look at the resulting .s files?
