* lisp/emacs-lisp/checkdoc.el (checkdoc--next-docstring): Don't
bug out on malformed Emacs Lisp (bug#34760).
(checkdoc-file-comments-engine): Don't bug out on empty buffers.
* lisp/emacs-lisp/bytecomp.el (byte-compile-cond-use-jump-table): Set
to nil. We can turn this back on again when Bug#36447 is solved and
we handle dumped hash tables correctly.
Use a more precise test to determine whether the input to `regexp-opt'
is safe to optimise when KEEP-ORDER is non-nil, permitting more inputs
to be optimised than before. For example, ("good" "goal" "go") is now
accepted.
* lisp/emacs-lisp/regexp-opt.el (regexp-opt):
More precise test for whether the list is safe w.r.t. KEEP-ORDER.
(regexp-opt--contains-prefix): Remove.
* test/lisp/emacs-lisp/regexp-opt-tests.el: Use lexical-binding.
(regexp-opt-test--permutation, regexp-opt-test--factorial)
(regexp-opt-test--permutations, regexp-opt-test--match-all)
(regexp-opt-test--check-perm, regexp-opt-test--explain-perm)
(regexp-opt-keep-order): Test KEEP-ORDER.
Previously:
package--incompatible-p: Wrong type argument: package-desc, nil
Now:
No package specified
* lisp/emacs-lisp/package.el (describe-package): Don't use ## as input.
When comparing against symbols, turn `equal' and `eql' into `eq',
and `member' and `memql' into `memq'.
* lisp/emacs-lisp/byte-opt.el (byte-optimize--constant-symbol-p)
(byte-optimize-equal, byte-optimize-member): New.
(member, memql, equal, eql): Use new byte-optimizers.
* lisp/emacs-lisp/re-builder.el (reb-copy): Work in the presence
of newlines in the regexps.
(reb-change-syntax): Use a dedicated history variable.
(reb-fontify-string-re): Fontify sub-matches.

(reb-mark-non-matching-parenthesis): Match parenthesis.
(reb-restart-font-lock): New function.
* lisp/emacs-lisp/re-builder.el (reb-mode-map): Add divider some
dividers (bug#6347).
* lisp/emacs-lisp/rx.el (rx-regexp, rx-literal): Check the cadr of the
form for stringness, not the form itself.
* test/lisp/emacs-lisp/rx-tests.el (rx-to-string-lisp-forms): New test.
* lisp/emacs-lisp/rx.el (rx-regexp): Allow non-string forms.

non-constant case.

subforms.
(rx): Document new form, wrap non-constant forms with concat call.
* test/lisp/emacs-lisp/rx-tests.el (rx-tests--match): New macro.
(rx-nonstring-expr, rx-nonstring-expr-non-greedy): New tests.
* etc/NEWS: Announce changes.

* lisp/emacs-lisp/tabulated-list.el (tabulated-list-mode-map):
Move widen/narrow to `}' and `{'.

* lisp/dired-x.el, lisp/dired-aux.el, lisp/calendar/calendar.el:
Don't use byte-compile-dynamic any more.
* lisp/emacs-lisp/eieio.el (object-print):
* lisp/emacs-lisp/eieio-base.el (eieio-object-set-name-string):
Move the defgeneric before the defmethod, because that makes more
sense.
* lisp/emacs-lisp/bytecomp.el (byte-compile-initial-macro-environment):
Change with-suppressed-warnings so it also affects the macro-expansion of
the body.
A single `cond' form can how be compiled to any number of switch ops,
optionally interspersed with non-switch conditions.
Previously, switch ops would only be used for whole `cond' forms
containing no other tests.
* lisp/emacs-lisp/bytecomp.el (byte-compile--cond-vars):
Rename from `byte-compile-cond-vars'.
(byte-compile--default-val): Remove.
(byte-compile--cond-switch-prefix):
Replace `byte-compile-cond-jump-table-info'; now also returns
trailing non-switch clauses.
(byte-compile-cond-jump-table): New arguments; no longer compiles
the default case.
(byte-compile-cond): Look for and compile switches at any place in the
list of clauses.
* test/lisp/emacs-lisp/bytecomp-tests.el (byte-opt-testsuite-arith-data):
Add test expression.
Allow any mixture of `eq', `eql' and `equal', `memq', `memql' and
`member' in a switch-like `cond' to be compiled into a single switch.
* lisp/emacs-lisp/bytecomp.el (byte-compile--common-test): New.
(byte-compile-cond-jump-table-info): Use most specific common test.
* test/lisp/emacs-lisp/bytecomp-tests.el (byte-opt-testsuite-arith-data):
Add test cases for multi-value clause cond forms.
* lisp/emacs-lisp/pcase.el (pcase--u1):
Use the most specific of `memq', `memql' and `member' in or-patterns
with constant cases. This improves performance and may help the byte-code
compiler generate a switch.
* test/lisp/emacs-lisp/pcase-tests.el (pcase-tests-member):
Add mixed-type or-pattern test cases.
* lisp/emacs-lisp/bytecomp.el (byte-compile-cond-jump-table-info):
Expand `memq', `memql' and `member' to their corresponding
equality tests.
(byte-compile-cond-jump-table): Cases now have multiple values.
* lisp/emacs-lisp/byte-opt.el (byte-decompile-bytecode-1)
(byte-optimize-lapcode): Don't assume switch hash tables to be injective.
* lisp/cus-dep.el (custom-make-dependencies): Rewrite to use
reporter to report progress instead of how many files we've
processed.
* lisp/emacs-lisp/byte-run.el (byte-compile-info-string): New function.
(byte-compile-info-message): Use it.
* lisp/emacs-lisp/byte-run.el (byte-compile-info-message): New
function to outout informational messages during byte compilation.
* lisp/emacs-lisp/autoload.el (update-directory-autoloads): Use it
to report progress when scraping autoloads during bootstrap (which
may take half a minute).
* lisp/emacs-lisp/eieio-base.el (eieio-object-set-name-string):
Move the generic definition of this method to here from eieio.el
and place it after the cl-method definition. This avoids a
warning about it being obsolete when doing macro expansion.
* lisp/emacs-lisp/eieio.el (object-print): Move method definition
to before generic definition because the generic definition
obsoletes the method, which will then output a warning from when
macroexpanding.
* lisp/cedet/ede/base.el (ede-target): Inherit from eieio-named so
that if you're customizing objects via eieio-object-value-get, you
can set the name.
* lisp/emacs-lisp/eieio-custom.el (eieio-object-value-get): Don't
use obsolete function `eieio-object-set-name-string'.
* lisp/emacs-lisp/eieio.el (cl-print-object): Suppress the warning
about object-print being obsolete, since there are no in-tree
methods like that any more.
* lisp/emacs-lisp/cl-generic.el (cl-defmethod): Pass the symbol
name on to `byte-compile-warning-enabled-p' to make
with-suppressed-warnings work in cl-defmethods, too.
* lisp/cedet/semantic/db-el.el (object-print): Ditto.

* lisp/cedet/semantic/db-global.el (object-print): Ditto.

* lisp/cedet/semantic/db.el (semanticdb-debug-info): New method.
(object-print): Rewritten to be cl-print-object.
* lisp/emacs-lisp/eieio.el (eieio-object-name): Allow the EXTRA
argument to be a list of strings.
