You have to measure.
Indeed.
Here's a start:
The program has way too many things pre-defined, and the semantics are such that workWithDoubles can be completely eliminated... So you are not measuring what you want to be measuring. Make stuff depend on argc, and print the result of calculations or do something else such that the calculation must be performed. When measuring without LTO, probably attaching @weak onto the workWith* functions will work too. (pragma(inline, false) does not prevent reasoning about the function)
