It is: "Lengths are measured in addressable storage units (bytes)." (which is in the manual just fine; gccint of course, not the user manual). > Which suggests that it should be mentioned in the manual (whatever > label it ends up with).

It is documented with -dp (I'll document it prints insn cost too). Segher
