A supplementary commit to that on 2022-04-18:
* lisp/emacs-lisp/bytecomp.el (byte-compile--first-symbol-with-pos): Handle
vectors and records correctly.
* lisp/emacs-lisp/byte-run.el (byte-run--ssp-seen): Correct the doc string.
Also increment a loop counter. This should fix bug #54248.
* lisp/emacs-lisp/byte-run.el (byte-run--strip-vector/record): increment the
loop counter 'i' in the main loop.
* lisp/emacs-lisp/bytecomp.el (byte-compile-out): call
byte-run-strip-symbol-positions on operands which are one-element lists.
This fixes bug #54098.
* lisp/emacs-lisp/byte-run.el (byte-run--strip-list)
(byte-run--strip-vector/record): New functions. These alter a list or
vector/record structure only where a symbol with position gets replaced by a
bare symbol.
(byte-run-strip-symbol-positions): Reformulate to use the two new functions.
(function-put): No longer strip positions from the second and third arguments.
* lisp/emacs-lisp/bytecomp.el (byte-compile-out): Remove the senseless
"stripping" of putative symbol positions from OPERAND, which is nil or a
number.
This happened with the tags of a condition-case. Also fix the detection of
circular lists while stripping the positions from symbols with position.
* lisp/emacs-lisp/byte-run.el (byte-run--circular-list-p): Remove.
(byte-run--strip-s-p-1): Write a value of t into a hash table for each cons or
vector/record encountered. (This is to prevent loops with circular
structures.) This is now done for all arguments, not just those detected as
circular lists.
* lisp/emacs-lisp/bytecomp.el (byte-compile-file-form-defvar)
(byte-compile-form, byte-compile-dynamic-variable-op)
(byte-compile-constant, byte-compile-push-constant): Remove redundant calls to
`bare-symbol'.
(byte-compile-lambda): call `byte-run-strip-symbol-positions' on the arglist.
(byte-compile-out): call `byte-run-strip-symbol-positions' on the operand.
This is the main call to this function in bytecomp.el.
* src/fns.c (hashfn_eq): Strip the position from an argument which is a symbol
with position.
(hash_lookup): No longer strip a position from a symbol with position.
(sxhash_obj): Add handling for symbols with position, substituting their bare
symbols when symbols with position are enabled.
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.
The position return by read-positioning-symbols is now the position in the
buffer, rather than the offset from the start of a form, enabling warning
positions in other parts of the buffer to be output.
* src/lisp.h (lisp_h_EQ): Add XLI casts so that it compiles cleanly.
* src/data.c (Fremove_pos_from_symbol): New DEFUN.
* src/lread.c (readchar_count): renamed to readchar_offset.
(read_internal_start) Initialize readchar_offset to the buffer's point when
STREAM is a buffer.
* lisp/emacs-lisp/bytecomp.el (byte-compile-warning-prefix): Amend to use
OFFSET as a buffer position, not an offset from the start of a form.
(byte-compile-warn): Remove symbol positions from any shape of ARGS, not just
a symbol with position.
* lisp/emacs-lisp/cconv.c (cconv-convert): In the :unused case, position the
new IGNORE symbol with the VAR it has replaced.
* lisp/emacs-lisp/macroexp.el (macroexp--warn-wrap, macroexp-warn-and-return):
Add an extra position parameter to each.
* lisp/emacs-lisp/bindat.el (bindat-type), lisp/emacs-lisp/byte-run.el
(defmacro, defun), lisp/emacs-lisp/cconv.el (cconv--convert-func-body)
(cconv-convert), lisp/emacs-lisp/cl-generic.el (cl-defmethod),
lisp/emacs-lisp/cl-macs.el (cl-symbol-macrolet, cl-defstruct),
lisp/emacs-lisp/easy-mmode.el (define-minor-mode),
lisp/emacs-lisp/eieio-core.el (eieio-oref, eieio-oref-default)
(eieio-oset-default), lisp/emacs-lisp/eieio.el (defclass),
lisp/emacs-lisp/gv.el (gv-ref), lisp/emacs-lisp/macroexp.el
(macroexp-macroexpand, macroexp--unfold-lambda, macroexp--expand-all),
lisp/emacs-lisp/pcase.el (pcase-compile-patterns, pcase--u1): Add an extra
position argument to each call of macroexp-warn-and-return.
* lisp/emacs-lisp/byte-run.el (byte-run--set-compiler-macro):
Don't warn when a compiler macro with lambda-form expander does not
use all the arguments of the function. Nobody expected any warning
since the arguments look like free variables inside the lambda form.
Instead of warning about unused vars during the analysis phase of
closure conversion, do it in the actual closure conversion by
annotating the code with "unused" warnings, so that the warnings
get emitted later by the bytecomp phase, like all other warnings,
at which point the line-number info is a bit less imprecise.
Take advantage of this change to wrap the expressions of unused
let-bound vars inside (ignore ...) so the byte-compiler can better
optimize them away.
Finally, promote `macroexp--warn-and-return` to "official" status
by removing its "--" marker.
(cconv-captured+mutated, cconv-lambda-candidates): Remove vars.
(cconv-var-classification): New var to replace them.
(cconv-warnings-only): Delete function.
(cconv--warn-unused-msg, cconv--var-classification): New functions.
(cconv--convert-funcbody): Add warnings for unused args.
(cconv-convert): Add warnings for unused vars in `let` and `condition-case`.
(cconv--analyze-use): Don't emit an "unused var" warning any more,
but instead remember the fact in `cconv-var-classification`.
* lisp/emacs-lisp/bytecomp.el (byte-compile-force-lexical-warnings):
Remove variable.
(byte-compile-preprocess): Remove corresponding case.
* lisp/emacs-lisp/pcase.el (pcase--if): Don't throw away `test` effects.
(\`):
* lisp/emacs-lisp/cl-macs.el (cl--do-arglist): Use `car-safe` instead
of `car`, so it can more easily be removed by the optimizer if the
result is not used.
* lisp/emacs-lisp/macroexp.el (macroexp--warn-wrap): New function.
(macroexp-warn-and-return): Rename from `macroexp--warn-and-return`.
For discussion, see the following thread:
https://lists.gnu.org/r/emacs-devel/2021-02/msg01666.html
* lisp/emacs-lisp/byte-run.el (byte-run--set-completion): Quote with
'function' for syntactical consistency with other declare form
properties. This allows writing (declare (completion foo)) instead
of (declare (completion 'foo)).

* lisp/gnus/gnus-sum.el (gnus-summary-make-menu-bar): Prefer
function-put over put for function symbols.

form; it is no longer needed.
* lisp/emacs-lisp/byte-run.el (byte-run--set-modes): Change from
being a predicate to storing the modes. This allows using the
modes for positive command discovery, too.
* src/data.c (Fcommand_modes): Look at the `command-modes' symbol
property, too.
* doc/lispref/functions.texi (Declare Form): Document the new
`completion' and `modes' declarations.

`macroexp--warn-and-return` rather than `message`.
* lisp/emacs-lisp/macroexp.el: Fix `macroexp--compiling-p`.
(macroexp--warn-and-return): Don't try and detect repetition on forms
like `nil`.
(macroexp-macroexpand): Don't forget to bind `macroexpand-all-environment`.
* lisp/emacs-lisp/byte-run.el (defsubst): Do not add a speed
declaration as this breaks a pre existing ones if present but
rather calls directly `byte-run--set-speed'.
* lisp/emacs-lisp/byte-run.el (byte-compile-info): New function
that's more flexible that replaces 'byte-compile-info-string' and
'byte-compile-info-message'.
