* lisp/emacs-lisp/comp.el (native--compile-async): Don't start the
async compilation if we didn't add anything. This avoids spurious
"Compilation finished" messages in the *Async* buffer when it
turned out that all the files we considered nativecomping were
skipped.
* lisp/loadup.el (featurep): Define the hash table in nativecomp
builds (but not otherwise). A more natural place to define this
would be in comp.el, but comp.el isn't loaded yet when we load the
.elc file that updates comp--no-native-compile. We could change
the load order and move the definition to comp.el, though.
* lisp/emacs-lisp/bytecomp.el (byte-compile-from-buffer): Allow
inhibiting nativecomp earlier (bug#57627).
* lisp/emacs-lisp/comp.el (native-compile-async-skip-p): Use the data.
* doc/lispref/compile.texi (Native-Compilation Variables):
Document it.
* lisp/startup.el (normal-top-level): Set
inhibit-native-compilation from environment variable.
* lisp/subr.el (native-comp-deferred-compilation): Make obsolete.
* lisp/emacs-lisp/comp.el (comp-trampoline-compile): Don't write
trampolines to disk.
* lisp/progmodes/elisp-mode.el
(emacs-lisp-native-compile-and-load): Adjust.
* src/comp.c (syms_of_comp): New variable
inhibit-native-compilation.
(maybe_defer_native_compilation): Use it.
* src/character.c (Fmax_char): Accept an optional argument
UNICODE, and, if non-nil, return the maximum codepoint defined by
Unicode.
* lisp/emacs-lisp/comp.el (comp-known-type-specifiers): Update the
signature of 'max-char'.
* etc/NEWS:
* doc/lispref/nonascii.texi (Character Codes): Update the
documentation of 'max-char'.
* src/editfns.c (narrow_to_region_internal): New function, which
contains the body previously in 'Fnarrow_to_region' but accepts
a third argument.
(Fnarrow_to_region): Use the new function. Update the docstring.
(Fwiden): Update the docstring.
* src/lisp.h: Prototype of the new function.
* src/xdisp.c (handle_fontified_prop): Use the new function instead
of 'Fnarrow_to_region'.
* src/process.c (Finternal_default_process_filter):
* src/lread.c (readevalloop): Remove the third argument to
'Fnarrow_to_region'.
* src/bytecode.c (exec_byte_code):
* lisp/emacs-lisp/comp.el (comp-limplify-lap-inst):
* lisp/emacs-lisp/bytecomp.el: Restore the statu quo ante.
* etc/NEWS: Remove the entry about the new optional argument.
* doc/lispref/positions.texi (Narrowing): Update the documentation.
* lisp/emacs-lisp/comp.el (comp-final): Mark async worker tmp file
as utf-8.
* test/src/comp-tests.el (48029-1): New test.
* test/src/comp-resources/comp-test-funcs.el
(comp-test-48029-nonascii-žžž-f): New function.
* lisp/emacs-lisp/comp.el (comp-func): Add a command-modes slot.
(comp-spill-lap-function, comp-intern-func-in-ctxt): Fill it.
(comp-emit-for-top-level, comp-emit-lambda-for-top-level): Use it.
* src/alloc.c (mark_object): Mark the command_modes slot.
* src/comp.c (make_subr): Add a command_modes parameter.
(Fcomp__register_lambda): Use it.
(Fcomp__register_subr): Ditto.
* src/data.c (Fcommand_modes): Output the command_modes data for subrs
(bug#54437).
* src/lisp.h (GCALIGNED_STRUCT): Add a command_modes slot.
* src/pdumper.c (dump_subr): Update hash.
(dump_subr): Dump the command_modes slot.
The `function-history` patch introduced a regression which caused
spurious compiler warnings. Fix it.
The new code also fixes a bug in the old code, thus causing some
new non-spurious warnings. Fix them as well.
* lisp/emacs-lisp/bytecomp.el (byte-compile-eval): Adjust to changes in
`load-history`.
* lisp/gnus/gnus-group.el (nnrss-discover-feed)
(nnrss-save-server-data): Use `declare-function`.
* lisp/cedet/semantic/wisent/comp.el (wisent-defcontext)
(wisent-with-context):
* lisp/emacs-lisp/comp.el (comp-op-case): Silence compiler warning.
* lisp/emacs-lisp/comp.el (batch-native-compile): Add return
value.
(batch-byte+native-compile): Touch the produced .eln after the
corresponding .elc is produced.
It was implemented but never generated, originally intended for
TCO in the pre-lexbind era (which was semantically dubious anyway).
Removing it speeds up the interpreter because there is no longer any
need for the outermost `count` variable unless checking is enabled.
* lisp/emacs-lisp/bytecomp.el:
* lisp/emacs-lisp/comp.el (comp-limplify-lap-inst):
* src/bytecode.c (BYTE_CODES, exec_byte_code):
Remove definition and implementation of unbind-all, freeing up the opcode
for other purposes.
* lisp/emacs-lisp/bytecomp.el (byte-to-native-output-buffer-file):
Rename from `byte-to-native-output-file'.
(byte-write-target-file): Update.
(byte-compile-file): Write the temporary .elc only when not native
compiling.
(byte-compile-file): Kill the .elc buffer only when not native
compiling.
* lisp/emacs-lisp/comp.el (batch-byte+native-compile): Instead of just
renaming the temporary .elc make use of `byte-write-target-file' to
write it down and kill the temporary buffer.
* lisp/emacs-lisp/comp.el (comp-c-func-name): Fix native compilation
for functions with function names containing non trivial
characters (bug#52833).

Do not merge to master
No longer strip positions from symbols before each use of a form, instead
relying on the low level C routines to do the right thing. Instead strip them
from miscellaneous places where this is needed. Stip them alson in
`function-put'.
Push forms onto byte-compile-form-stack and pop them "by hand" rather than by
binding the variable at each pushing, so that it will still have its data
after an error has been thrown and caught by a condition case. This gives an
source position to the ensuing error message.
* lisp/emacs-lisp/byte-run.el (byte-run--ssp-seen, byte-run--circular-list-p)
(byte-run--strip-s-p-1, byte-run-strip-symbol-positions): New functions and
variables, which together implement stripping of symbol positions. The latest
(?final) version modifies the argument in place rather than making a copy.
(function-put): Strip symbol positions from all of the arguments before doing
the `put'.
* lisp/emacs-lisp/bytecomp.el (byte-compile--form-stack): has been renamed to
byte-compile-form-stack and moved to macroexp.el.
(byte-compile-initial-macro-environment (eval-and-compile)): Replace
macroexpand-all-toplevel with macroexpand--all-toplevel.
(displaying-byte-compile-warnings): bind byte-compile-form-stack here.
(byte-compile-toplevel-file-form, byte-compile-form): Push the top level form
onto byte-compile-form-stack (whereas formally the variable was bound at each
pushing). Manually pop this from of the variable at the end of the function.
* lisp/emacs-lisp/cl-macs.el (cl-define-compiler-macro): Remove the symbol
stripping.
* lisp/emacs-lisp/comp.el (comp--native-compile): Set max-specpdl-size to at
least 5000 (previously it was 2500). Bind print-symbols-bare to t.
* lisp/emacs-lisp/macroexp.el (byte-compile-form-stack): Definition move here
from bytecomp.el for easier compilation.
(byte-compile-strip-symbol-positions and associated functions): Removed.
(macro--expand-all): push argument FORM onto byte-compile-form-stack at the
start of this function, and pop it off at the end.
(internal-macroexpand-for-load): No longer strip symbol positions. Bind
symbols-with-pos-enabled and print-symbols-bare to t.
* lisp/help.el (help--make-usage): Strip any position from argument ARG.
* src/fns.c (Fput): No longer strip symbol positions from any of the
arguments.
