* lib/malloc/scratch_buffer_dupfree.c: New file, from Gnulib
(originally from glibc 2.33 code).
This is needed on macOS and some other platforms;
I forgot to commit it in the most recent Gnulib update.
With this commit unreachable basic blocks are pruned automatically by
comp-ssa relying on dominance analysis. This solves the issue of
unreachable cluster of basic blocks referencing each other.
* lisp/emacs-lisp/comp.el (comp-block-lap): New `no-ret' slot.
(comp-compute-dominator-tree): Update.
(comp-remove-unreachable-blocks): New functions.
(comp-ssa): Update to call `comp-remove-unreachable-blocks'.
(comp-clean-orphan-blocks): Delete.
(comp-rewrite-non-locals): Update and simplify.
Introduce 'unreachable' as LIMPLE operater so we can handle correctly
in the CFG functions throwing values or signaling errors.
* src/comp.c (retrive_block): Better error diagnostic.
(emit_limple_insn): Add `unreachable'.
(compile_function): Fix block iteration.
(syms_of_comp): Define 'Qunreachable'.
* lisp/emacs-lisp/comp.el (comp-block): New variable.
(comp-block-lap): Add `non-ret-insn' slot.
(comp-branch-op-p): New predicate.
(comp-limple-lock-keywords): Color `unreachable' as red.
(comp-compute-edges): Add `unreachable'.
(comp-fwprop-call): Store non returning function call.
(comp-fwprop*): Update.
(comp-clean-orphan-blocks, comp-rewrite-non-locals): New functions.
(comp-fwprop): Call `comp-rewrite-non-locals'.
* test/src/comp-tests.el (comp-tests-type-spec-tests): Add two
tests.
* test/src/comp-test-funcs.el (comp-test-non-local-1)
(comp-test-non-local-2, comp-test-non-local-3)
(comp-test-non-local-4): New functions.
ruby-mode uses 'cl-evenp' at runtime, so cl-lib must be available at
runtime as well.
* lisp/progmodes/ruby-mode.el (cl-lib): Require at runtime as well.

c6d5555646 Display messages sent using ERC's /say
c156723769 Fix Rmail summary display when From: header is malformed
* src/process.c (Fnetwork_lookup_address_info):
* doc/lispref/processes.texi (Misc Network): Document the error
message emitted by 'network-lookup-address-info' when it fails.
This speeds up syntax-propertize almost 2x.
* lisp/progmodes/ruby-mode.el (ruby-syntax-propertize):
Optimize expression expansion too.
(ruby-syntax-propertize-expansion, ruby-font-lock-keywords)
(ruby-expression-expansion-re): Update to match.
* lisp/progmodes/ruby-mode.el (ruby-syntax-propertize):
Add a rule for setter symbols (bug#42846).
(ruby-font-lock-keywords): Remove dead code, left over from before
commit 26f9c507.
* lisp/progmodes/ruby-mode.el (ruby-smie--bosp):
Handle '=' being part of a symbol (bug#42846).
* test/lisp/progmodes/ruby-mode-resources/ruby.rb:
Add corresponding indentation examples.
Otherwise, an innocent string like " " will mysteriously
pickup properties from some other minor mode.
Making this a separate commit in hopes of raising attention to this
possible bug.
* lisp/progmodes/flymake.el (flymake--mode-line-counter): Must
explicily create a new string unpropertized string
These would be the kind of "This file needs a ;;Code section" and
such.
* lisp/progmodes/elisp-mode.el (elisp-flymake-checkdoc): Resist
checkdoc diagnostics with no end position.
* lisp/progmodes/cc-awk.el (awk-font-lock-keywords): Replace a hard use of
c-preprocessor-face-name by an `eval' expression which evaluates it.
* lisp/progmodes/cc-engine.el (c-in-knr-argdecl, c-laomib-put-cache)
(c-laomib-fix-elt): Remove unused bound variables.
* lisp/gnus/gnus-art.el (gnus-mime-action-alist): Remove duplicated
"toggle display" entry and call the appropriate function for the "view
as charset" action (bug#45561).
* doc/lispref/lists.texi (List Variables): Update manual.
* lisp/subr.el (add-to-ordered-list): Allow using a test
predicate, and make slightly more efficient (bug#45539).
This works even if another thread or process resets the resource limit
for open file descriptors, e.g., using 'prlimit' on GNU/Linux.
* src/process.c (create_process, create_pty, Fmake_pipe_process)
(Fmake_serial_process, connect_network_socket)
(server_accept_connection): Limit file descriptors to FD_SETSIZE.
* test/src/process-tests.el (process-tests--with-raised-rlimit): New
helper macro.
(process-tests--fd-setsize-test): Rename from
'process-tests--with-many-pipes'. Increase resource limit during test
if possible.
(process-tests/fd-setsize-no-crash/make-process)
(process-tests/fd-setsize-no-crash/make-pipe-process)
(process-tests/fd-setsize-no-crash/make-network-process)
(process-tests--new-pty): Rename callers.
