The obsolete lazy-loaded bytecode feature, enabled by `byte-compile-dynamic`, slows down Lisp execution even when not in use because every call to a bytecode function has to check that function for laziness. This change forces up-front loading of all lazy bytecode so that we can remove all those checks. (Dynamically loaded doc strings are not affected.) There is no point in generating lazy bytecode any more so we stop doing that; this simplifies the compiler. `byte-compile-dynamic` now has no effect. This is a fully compatible change; the few remaining users of `byte-compile-dynamic` should not notice any difference. * src/lread.c (bytecode_from_rev_list): Force eager loading of lazy bytecode. * src/bytecode.c (exec_byte_code): Remove lazy bytecode checks. * src/eval.c (fetch_and_exec_byte_code, Ffetch_bytecode): Remove. (funcall_lambda): Call exec_byte_code directly, avoiding checks. * lisp/subr.el (fetch-bytecode): New definition, obsolete no-op. * lisp/emacs-lisp/disass.el (disassemble-1): * lisp/emacs-lisp/bytecomp.el (byte-compile-unfold-bcf): Remove calls to fetch-bytecode. (byte-compile-dynamic): Update doc string. (byte-compile-close-variables, byte-compile-from-buffer) (byte-compile-insert-header, byte-compile-output-file-form) (byte-compile--output-docform-recurse, byte-compile-output-docform) (byte-compile-file-form-defmumble): Remove effects of byte-compile-dynamic. * doc/lispref/compile.texi (Dynamic Loading): Remove node now that the entire `byte-compile-dynamic` facility has been rendered inert. * etc/NEWS: Announce changes. |

README for the Emacs Lisp Reference Manual.
* This directory contains the texinfo source files for the Emacs Lisp
Reference Manual.
* Report bugs in the Lisp Manual (or in Emacs) using M-x report-emacs-bug.
To ask questions, use the help-gnu-emacs mailing list.
* The Emacs Lisp Reference Manual is quite large. It totals around
1100 pages in smallbook format; the info files total around 3.0 megabytes.
* You can format this manual for Info, for printing hardcopy using TeX,
or for HTML.
* You can buy nicely printed copies from the Free Software Foundation.
Buying a manual from the Free Software Foundation helps support our GNU
development work. See <https://shop.fsf.org/>.
(At time of writing, this manual is out of print.)
* The master file for formatting this manual for Tex is called 'elisp.texi'.
It contains @include commands to include all the chapters that make up
the manual.
* This distribution contains a Makefile that you can use with GNU Make.
** To make an Info file, you need to install Texinfo, then run 'make info'.
** Use 'make elisp.pdf' or 'make elisp.html' to create PDF or HTML versions.
