It's not necessarily a code size savings in any case.
It can be, but the real benefits are stylistic
consistency and lack of mismatch between function
name and message.
If the code is refactored or copy/pasted into another
function, a moderately common defect is not modifying
the embedded function name in the message.
There may be some smallish savings if ever these
__func__ uses were converted to use %pf via some
internal standardized mechanism.
A negative to that approach is inlined functions would
take the function name of the parent not keep the
inlined function name.
