internal-optimize-switch

As with most 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 register-linking internal optimization is performed, resulting in faster but harder to debug code, which takes longer to compile. Initially true when compilation-speed is less than 2 and either speed is greater than 2 or debug is less than 3. Initially returns nil when compilation-speed is 2 or 3 regardless of other values.

See also optimize-large-functions-switch. See compiling.htm for information on the compiler.
