------- Comment #10 from aph at gcc dot gnu dot org 2009-04-23 16:23 ------- Officially, java doesn't have unsigned types for economy: believe it or not, Java was once intended to be a small language. However, there are not many unused bytecodes left, and a full set of signed instructions would use them all.
