slop
1. A one-sided fudge factor, that is, an allowance for error but in only one of two directions. For example, if you need a piece of wire 10 feet long and have to guess when you cut it, you make very sure to cut it too long, by a large amount if necessary, rather than too short by even a little bit, because you can always cut off the slop but you can' t paste it back on again. When discrete quantities are involved, slop is often introduced to avoid the possibility of being on the losing side of a fencepost error. 2. The percentage of "extra" code generated by a compiler over the size of equivalent assembly code produced by hand-hacking i.e. the space (or maybe time) you lose because you didn' t do it yourself. This number is often used as a measure of the quality of a compiler slop below 5% is very good, and 10% is usually acceptable. Modern compilers, especially on RISCs, may actually have *negative* slop that is, they may generate better code than humans. This is one of the reasons assembler programming is becoming less common.
