trust-declarations-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, the compiler will trust declarations in code (perhaps other than dynamic-extent declarations -- see trust-dynamic-extent-declarations-switch) and produce code (when it can) that is optimized given the declarations. These declarations typically specify the type of values of variables. If nil, declarations will be ignored -- except (declare notinline) and (declare special) which are always complied with.

See compiling.htm for information on the compiler.
