$Revision: 5.0.2.3 $
Package: COMPILER
The value of this variable can be t, nil, or a function object that accepts four arguments and returns t or nil. The arguments passed to the function will be the values of the safety, space, speed, and debug optimization qualities, in that order. nil is equivalent to a function that always returns nil and t to a function that always returns t. When we say t (or true) or nil (or false) in the text below, we mean that the function returns, respectively, t or nil.
When true, the compiler performs peephole optimization. Peephole optimizations include removing redundant instructions, such as a jump to the immediately following location. Initially true when speed is greater than 0.
