| Allegro CL version 8.2 Significantly revised from 8.1. 8.1 version |
As with all 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
.
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.
