3.2.2.6 Minimal Compilation

Minimal compilation is defined as follows:

*

All compiler macro calls appearing in the source code being compiled are expanded, if at all, at compile time; they will not be expanded at run time.

*

All macro and symbol macro calls appearing in the source code being compiled are expanded at compile time in such a way that they will not be expanded again at run time. macrolet

and symbol-macrolet

are effectively replaced by forms corresponding to their bodies in which calls to macros are replaced by their expansions.

*

The first argument in a load-time-value

form in source code processed by compile

is evaluated at compile time; in source code processed by compile-file , the compiler arranges for it to be evaluated at load time. In either case, the result of the evaluation is remembered and used later as the value of the load-time-value form at execution time.
