tail-call-self-merge-switch

As with all compiler switch variables, 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 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.

If true, compiler will perform self-tail-merging (for functions which call themselves). This switch will affect code only when true at the beginning of the function being self-called (and no other time).

See Tail merging discussion for more information on tail-merging. Initially true when speed is greater than 0.

See compiling.htm for information on the compiler.
