Compiler Arguments
block compilation arguments
The :block-compile and :entry-points arguments toextensions:compile-from-stream and (page
)compile-file provide overall
control of block compilation, and allow block compilation without requiring
modification of the program source.
There are three possible values of the :block-compile argument:
- nil
- Do no compile-time resolution of global function
names, not even for self-recursive calls. This inhibits any
start-block declarations appearing in the file, allowing all
functions to be incrementally redefined.
- t
- Start compiling in block compilation mode. This is
mainly useful for block compiling small files that contain no
start-block declarations. See also the :entry-points
argument.
- :specified
- Start compiling in form-at-a-time mode, but
exploit start-block declarations and compile self-recursive
calls as local calls. Normally :specified is the default for
this argument (see ** (page
)block-compile-default.)
The :entry-points argument can be used in conjunction with:block-compile t to specify the entry-points to a
block-compiled file. If not specified or nil, all global functions
will be compiled as entry points. When :block-compile is not
t, this argument is ignored.
[Variable]
**
block-compile-default
This variable determines the default value for the
:block-compile argument to compile-file and
compile-from-stream. The initial value of this variable is
:specified, but nil is sometimes useful for totally
inhibiting block compilation.
