This section documents the variables that control
native-compilation.
@defvar inhibit-automatic-native-compilation
If your Emacs has support for native compilation, Emacs will (by
default) compile the Lisp files you're loading in the background, and
then install the native-compiled versions of the functions. If you
wish to disable this, you can set this variable to non-@code{nil}. If
you want to set it permanently, this should probably be done from the
early init file, since setting it in the normal init file is probably
too late.
While setting this variable disables automatic compilation of Lisp
files, the compiler may still be invoked to install @dfn{trampolines}
if any built-in functions are redefined. However, these trampolines
will not get written to your cache directory.
You can also use the @samp{EMACS_INHIBIT_AUTOMATIC_NATIVE_COMPILATION}
environment variable to disable native compilation.

@defvar native-comp-jit-compilation
This variable, if non-@code{nil}, enables asynchronous (a.k.a.@:
@dfn{just-in-time}, or @acronym{JIT}) native compilation of the
@file{*.elc} files loaded by Emacs for which the corresponding
@file{*.eln} files do not already exist. This JIT compilation uses
separate Emacs sub-processes running in batch mode, according to the
value of @code{native-comp-async-jobs-number}. When the JIT
compilation of a Lisp file finishes successfully, the resulting
@file{.eln} file is loaded and its code replaces the definition of
functions provided by the @file{.elc} file.
@end defvar
@cindex trampolines, in native compilation
Setting the value of @code{native-comp-jit-compilation} to@code{nil}
disables JIT native compilation. However, even when JIT native
compilation is disabled, Emacs might still need to start asynchronous
native compilation subprocesses to produce @dfn{trampolines}. To
control this, use a separate variable, described below.
@defvar native-comp-enable-subr-trampolines
This variable controls generation of trampolines. A trampoline is a
small piece of native code required to allow calling Lisp primitives,
which were advised or redefined, from Lisp code that was
natively-compiled with @code{native-comp-speed} set to 2 or greater.
Emacs stores the generated trampolines on separate @file{*.eln} files.
By default, this variable's value is @code{t}, which enables the
generation of trampoline files; setting it to @code{nil} disables the
generation of trampolines. Note that if a trampoline needed for
advising or redefining a primitive is not available and cannot be
generated, calls to that primitive from natively-compiled Lisp will
ignore redefinitions and advices, and will behave as if the primitive
was called directly from C. Therefore, we don't recommend disabling
the trampoline generation, unless you know that all the trampolines
needed by your Lisp programs are already compiled and accessible to
Emacs.
The value of this variable can also be a string, in which case it is
interpreted as the name of a directory in which to store the generated
trampoline @file{*.eln} files, overriding the directories specified by
@code{native-comp-eln-load-path}. This is useful if you want the
trampolines to be generated as needed, but don't want to store them
under the user's @env{HOME} directory or the other public directories
where @file{*.eln} files are kept. However, unlike with directories
in @code{native-comp-eln-load-path}, the trampolines will be stored in
the directory given by the value of this variable, not in its
version-specific subdirectory.
If this variable is non-@code{nil}, and Emacs needs to produce a
trampoline, but it cannot find any writable directory to store the
trampoline, it will store it inside @code{temporary-file-directory}
(@pxref{Unique File Names}).
Trampolines produced when no writable directory is found to store
them, or when this variable is a string, will only be available for
the duration of the current Emacs session, because Emacs doesn't look
for trampolines in either of these places.
