peephole-optimize-switch

As with all compiler switch variables, the value of this variable can be t, nil, or a function object that accepts five arguments and returns t or nil. The arguments passed to the function will be the values of the safety, space, speed, debug, and compilation-speed 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 the value is a function and 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.

See compiling.htm for information on the compiler.
