optimize-fslot-value-switch

$Revision: 5.0.2.5 $

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 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, calls to ff:fslot-value-typed will be opencoded if possible. See fftype.htm. Initially true when speed is greater than safety.

See compiling.htm for information on the compiler.

See introduction.htm for a general description of the documentation and index.htm for an index.
