buffer-disposition in make-thread and its getter and setter.
* etc/NEWS: Add entry.
Handlers contain a sys_jmp_buf, which requires ambiguous scanning; on
Windows 64, sys_jmp_buf also requires 16-byte alignment, which IGC
does not provide on that platform.
* src/igc.c (igc_alloc_handler): Use 'igc_xzalloc_ambig', not 'alloc'.
* src/thread.c (run_thread): Free handlers.
This makes it necessary to allocate the buffer indirectly, as it needs
to be an MPS root rather than part of a normal pseudovector.

Remove to the above-named struct.
(android_init_thread_events, android_finalize_thread_events)
(android_get_poll_thread): New functions.
(android_run_select_thread): Accept a set of mutexes and
thread-local data as the first argument, and operate with them
rather than globals.

indicator.
(android_init_events): Properly abort after a fatal condition.
Enable interruptible polling on Android 5.1 and later, not 4.2.

thread_select, if threads are enabled. Adapt to per-thread
polling threads and only enable interruptible polling on Android
5.1 and later.
(android_before_select): New function.
* src/android.h (android_before_select): New declaration.
* src/thread.c (thread_select): Call `android_before_select'
before the global lock is released.
* doc/lispref/variables.texi (Intro to Buffer-Local): Fix typo
in documentation.
* src/data.c (KBOARD_OBJFWDP): Move to lisp.h.
(kboard_for_bindings): New variable.
(do_symval_forwarding, store_symval_forwarding): Call
kboard_for_bindings rather than retrieving this value directly.

Lisp_Kboard_Objfwd and WHERE be specified, save the binding
there. All callers changed.
* src/eval.c (specpdl_where): Adjust for changes in structure
layout.

* src/lisp.h (union specbinding) <let.where>: Convert into
union of KBOARD and Lisp_Object.
* src/thread.c (all_threads): Export.
* src/thread.h: Adjust correspondingly.
Much like the NS port, only the main thread receives input from
the user interface, which is fortunately not a major problem for
packages such as lsp-mode that create Lisp threads.
* configure.ac: Enable with_threads under Android.
* src/android.c (android_init_events): Set `main_thread_id' to
the ID of the main thread.
(setEmacsParams): Set new global variable `android_jvm' to the
JVM object, for the purpose of attaching Lisp threads to the
JVM.
(android_select): [THREADS_ENABLED]: If the caller isn't the
main thread, resort to pselect. Don't check query before select
returns.
(android_check_query): Export.
* src/android.h (_ANDROID_H_): Define new macro and update
prototypes.
* src/process.c (android_select_wrapper): New function.

This is the function that marks the C stack. Avoid confusion with the
new mark stack, a stack used in the GC mark phase.
* src/alloc.c (SETJMP_WILL_LIKELY_WORK, SETJMP_WILL_NOT_WORK)
(mark_stack, mark_c_stack):
* src/lisp.h:
* src/thread.c (mark_one_thread): Rename mark_stack to mark_c_stack.
Use a dedicated stack for bytecode, instead of using the C stack.
Stack frames are managed explicitly and we stay in the same
exec_byte_code activation throughout bytecode function calls and
returns. In other words, exec_byte_code no longer uses recursion
for calling bytecode functions.
This results in better performance, and bytecode recursion is no
longer limited by the size of the C stack. The bytecode stack is
currently of fixed size but overflow is handled gracefully by
signalling a Lisp error instead of the hard crash that we get now.
In addition, GC marking of the stack is now faster and more precise.
Full precision could be attained if desired.
* src/alloc.c (ATTRIBUTE_NO_SANITIZE_ADDRESS): Make non-static.
* src/bytecode.c (enum stack_frame_index, BC_STACK_SIZE)
(sf_get_ptr, sf_set_ptr, sf_get_lisp_ptr, sf_set_lisp_ptr)

* src/thread.h (struct bc_thread_state): New.
(struct thread_state): Add bytecode thread state.
Keep track of the end of specpdl explicitly since that is what we are
comparing against on critical code paths.
* src/eval.c (init_eval_once_for_pdumper, signal_or_quit)
(grow_specpdl_allocation):
* src/fileio.c (Fdo_auto_save):
* src/lisp.h (grow_specpdl):
* src/thread.c (run_thread, Fmake_thread):
* src/thread.h (struct thread_state):
Replace specpdl_size with specpdl_end, according to the equation
specpdl_end = specpdl + specpdl_size.
Make the context switch code handle buffer-local variables more
correctly by reusing the code originally written for `backtrace-eval`.
This has the side benefit of making the `saved_value` field unused.
* src/lisp.h (enum specbind_tag): Remove `saved_value` field.
(rebind_for_thread_switch, unbind_for_thread_switch): Delete decls.
(specpdl_unrewind): Declare function.

* src/thread.c (rebind_for_thread_switch, unbind_for_thread_switch):
Move from `eval.c` and rewrite using `specpdl_unrewind`.
* test/src/thread-tests.el (threads-test-bug48990): New test.
* test/Makefile.in (test_template): Add a + as suggested by make:
"warning: jobserver unavailable: using -j1. Add '+' to parent make rule".
Problem reported by Eli Zaretskii (Bug#41321).
* src/alloc.c (MALLOC_ALIGNMENT_BOUND): New constant.
(LISP_ALIGNMENT): Lower it to avoid crashes on MinGW and similarly
buggy platforms where malloc returns pointers not aligned to
alignof (max_align_t). But keep it higher on platforms where this
is known to work, as it helps GC performance.
(MALLOC_IS_LISP_ALIGNED): Define in terms of the other two.
* src/alloc.c (stacktop_sentry):
* src/thread.c (run_thread):
Don’t overalign or oversize stack sentries; they need to be
aligned only for pointers and Lisp_Object, not for arbitrary
pseudovector contents.

LISP_ALIGNMENT.

(sys_thread_create) [HAVE_PTHREAD_SETNAME_NP]: Use pthread_setname_np
to set the name of the newly created thread (Bug#38632).
* thread.c (Fmake_thread): Use ENCODE_SYSTEM instead of
ENCODE_UTF_8 on the thread name.
* src/w32fns.c (setup_w32_kbdhook): Don't initialize
is_debugger_present here...

Use ALLOCATE_ZEROED_PSEUDOVECTOR rather than zeroing by hand.

(BUFFER_REST_SIZE): Simplify by using VECSIZE and BUFFER_LISP_SIZE.
* src/lisp.h (PSEUDOVECSIZE): Base it on the last Lisp field,

Add ‘const’ to make the GC marking code a bit clearer.

* Makefile.in: Add @DUMPING@ substitution; add pdumper mode.
* .gitignore: Add make-fingerprint, temacs.in, fingerprint.c,
dmpstruct.h, and pdumper dump files.
Problem reported by Joseph Mingrone in:
https://lists.gnu.org/r/emacs-devel/2018-10/msg00238.html
While we’re at it, apply a similar fix to struct Lisp_Subr; this
removes the need for GCALIGNED_STRUCT_MEMBER and thus can shrink
struct Lisp_Subr a bit.
* configure.ac (HAVE_STRUCT_ATTRIBUTE_ALIGNED): Bring back this macro.
Although used only for performance (not to actually align
structures), we might as well take advantage of it.
* src/lisp.h (GCALIGNED_STRUCT_MEMBER): Remove; all uses removed.
(union Aligned_Lisp_Subr): New type, like struct Lisp_Subr but aligned.
* src/lisp.h (XSUBR, DEFUN):
* src/lread.c (defsubr): Use it. All callers changed.
* src/thread.c (union aligned_thread_state): New type.
(main_thread): Now of this type, so it’s aligned.
All uses changed.
* src/xmenu.c (syms_of_xmenu) [USE_GTK || USE_X_TOOLKIT]:
Adjust to union Aligned_Lisp_Subr change.
* src/thread.c (unmark_main_thread): New function.
* src/lisp.h (unmark_main_thread): Prototype it.
* src/alloc.c (garbage_collect_1): Call it after sweeping.
(Bug#33073)
* test/src/thread-tests.el (threads-test-bug33073): New test.
