The size of the function use nm tool

I used the command line nm --print-size --size-sort --radix=d abc.o and had a result like this:

0000000001843744 0000000000019313 W  _ZN4onnx15InternedString
0000000001843744 0000000000019313 W _ZN4onnx15InternedStrin
0000000000919072 0000000000078787 T _ZN4onnc15VanillaMathP

So, Is the size of the function and object 78787 bytes right?
