tail-call-self-merge-switch

$Revision: 5.0.2.3 $

Variable

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.]

If true, compiler will perform self-tail-merging (for functions which call themselves). See 8.6 Tail merging discussion in compiling.htm for more information on tail-merging. Initially true when speed is greater than 0.

See compiling.htm for information on the compiler.
