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.
