This is hard to detect because the +generated code is normally invisible to the programmer. + +This flag helps identify such cases.

For each distinct macro, it counts how many times it is used, and the +net effect on code size (in terms of lines of code, and bytes of code). The +code size evaluation uses the compiler's internal pretty-printing, and so will +be independent of the formatting in the original code. + +Note that the net effect of a macro may be negative.
