* Remove duplicate INLINE_HEADER_BEGINPaul Eggert2022-03-201-2/+0
| | | | | * src/thread.h: Remove duplicate INLINE_HEADER_BEGIN. Problem reportd by Mattias Engdegård.
* Port to gcc -D EMACS_EXTERN_INLINEPaul Eggert2022-03-191-0/+6
| | | | | | * src/comp.h, src/thread.h: Add INLINE_HEADER_BEGIN and INLINE_HEADER_END, since it uses INLINE. * src/emacs.c: Include these two files.
* Put bytecode stack frame metadata in a structMattias Engdegård2022-03-171-3/+5
| | | | | | | | | | | | | | | | | | Using a plain C struct instead of type-punning Lisp_Object stack slots makes the bytecode interpreter code more type-safe and potentially faster (from better alias analysis), and the special-purpose accessors are no longer needed. It also reduces the stack requirements when using 64-bit Lisp_Object on 32-bit platforms. * src/bytecode.c (enum stack_frame_index) (sf_get_ptr, sf_set_ptr, sf_get_lisp_ptr, sf_set_lisp_ptr, sf_get_saved_pc, sf_set_saved_pc): Remove. (BC_STACK_SIZE): Now in bytes, not Lisp words. (struct bc_frame): New. (init_bc_thread, mark_bytecode, Finternal_stack_stats, valid_sp) (exec_byte_code): * src/lisp.h (struct handler, get_act_rec, set_act_rec): Adapt to new struct bc_frame.
* Separate bytecode stackMattias Engdegård2022-03-131-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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) (sf_get_saved_pc, sf_set_saved_pc, init_bc_thread, free_bc_thread) (mark_bytecode, Finternal_stack_stats, valid_sp): New. (exec_byte_code): Adapt to use the new bytecode stack. (syms_of_bytecode): Add defsubr. * src/eval.c (unwind_to_catch): Restore saved stack frame.

* Maintain end of specpdl instead of sizeMattias Engdegård2022-03-121-4/+4
| | | | | | | | | | | | | | 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.

* * src/keyboard.c: Fix bug#5803.Stefan Monnier2020-12-121-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | A long time ago, `read_key_sequence` used to read the keymaps at the start, so if something happened between this start and the moment the user actually hits a key, `read_key_sequence` could end up using the wrong keymaps. To work around this problem, the code used `record_asynch_buffer_change` to try and trigger `read_key_sequence` to re-read the keymaps in some known cases. Several years ago, `read_key_sequence` was changed so as to read the keymaps only once the user hits a key, making this machinery now redundant (and also harmful apparently in bug#5803 because it introduces "spurious" events). So we here remove `record_asynch_buffer_change` and the `BUFFER_SWITCH_EVENT` and `Qbuffer_switch` pseudo-events it generated. * src/termhooks.h (enum event_kind): Delete `BUFFER_SWITCH_EVENT`. * src/keyboard.c: (record_asynch_buffer_change): Delete function. (syms_of_keyboard): Delete `Qbuffer_switch`. (force_auto_save_soon, readable_events) (kbd_buffer_store_buffered_event, kbd_buffer_get_event) (make_lispy_event): * src/xterm.c (handle_one_xevent): * src/w32term.c (w32_read_socket): * src/process.c (wait_reading_process_output) (read_and_dispose_of_process_output, exec_sentinel): Simplify accordingly.

| | | | | | | | | | | | | | | pthread_setname_np takes only a single argument on BSD and macOS, and affects the current thread only. * configure.ac: Add check for single-argument pthread_setname_np * src/systhread.c (sys_thread_set_name): New (w32 and pthread versions). (sys_thread_create): Remove name argument and name-setting.

(Fmake_mutex, Fmake_condition_variable, Fmake_thread): Use ALLOCATE_ZEROED_PSEUDOVECTOR rather than zeroing by hand. (mark_one_thread): No need to mark Lisp_Object members. (init_main_thread, init_threads_once): Remove. All uses removed.
* Allow gap before first non-Lisp pseudovec memberPaul Eggert2019-04-081-1/+1
| | | | | | | | | | | | | Problem reported by Keith David Bershatsky in: https://lists.gnu.org/r/emacs-devel/2019-04/msg00259.html Solution suggested by Stefan Monnier in: https://lists.gnu.org/r/emacs-devel/2019-04/msg00282.html * src/buffer.h (BUFFER_LISP_SIZE): Simplify by using PSEUDOVECSIZE. (BUFFER_REST_SIZE): Simplify by using VECSIZE and BUFFER_LISP_SIZE. * src/lisp.h (PSEUDOVECSIZE): Base it on the last Lisp field, not the first non-Lisp field. All callers changed. Callers without Lisp fields changed to use ALLOCATE_PLAIN_PSEUDOVECTOR. (ALLOCATE_PLAIN_PSEUDOVECTOR): New macro.

(TALLOC, RETALLOC): Remove. All uses replaced by usual allocators, which check for integer overflow. (extract_number): Redo without using ‘unsigned’.

(print_fastmap, print_partial_compiled_pattern, CHECK_INFINITE_LOOP) (regex_compile, analyze_first, bcmp_translate, mutually_exclusive_p) (re_match_2_internal): Use bool for booleans. (print_fastmap, regex_compile, execute_charset): Prefer int to unsigned where either will do.

* Use ‘const’ to clarify GC markingPaul Eggert2019-03-191-2/+2
| | | | | | | | | | | | | | | | | | | Add ‘const’ to make the GC marking code a bit clearer. This can also help the compiler in some cases, I think because GCC can now determine more often that the value of a static C variable can be cached when its address is now converted to ‘Lisp Object const *’ before escaping. * src/alloc.c (staticvec, mark_maybe_objects, mark_memory) (mark_stack, staticpro, mark_object_root_visitor) (garbage_collect_1): * src/pdumper.c (dump_ptr_referrer, dump_emacs_reloc_to_lv) (dump_emacs_reloc_to_emacs_ptr_raw, dump_root_visitor): * src/lisp.h (vcopy, struct gc_root_visitor): * src/sysdep.c (stack_overflow): * src/thread.c (mark_one_thread): * src/thread.h (struct thread_state): Use pointer-to-const instead of plain pointer in some GC-related places where either will do.

* | Use native alignment to access Lisp object dataPaul Eggert2018-06-101-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of using __builtin_assume_aligned (P, GCALIGNMENT) to tell GCC that P has alignment 8, use (T *) P where T is the type of the pointed-to object, to tell GCC that P has native alignment. This is simpler, matches the intent better, and should help simplify future improvements. Some of these changes are to pacify gcc -Wnull-dereference, since GCC is smarter about pointers now that Emacs no longer uses __builtin_assume_aligned; these minor changes should improve code efficiency slightly. On Fedora 28 x86-64 with default optimization this patch shrinks the size of the Emacs text segment by 0.36%. * src/conf_post.h (__has_builtin, __builtin_assume_aligned): Remove; no longer used. * src/dbusbind.c (XD_OBJECT_TO_DBUS_TYPE): Pacify -Wnull-dereference by using XCAR instead of CAR_SAFE and XCDR instead of CDR_SAFE when this is safe. * src/fileio.c (Fexpand_file_name): * src/font.c (clear_font_cache): Pacify -Wnull-dereference by removing unnecessary NILP test. * src/keyboard.c (xevent_start): New function. (read_char, read_key_sequence): Pacify -Wnull-dereference by using xevent_start instead of EVENT_START. * src/lisp.h (lisp_h_XUNTAG): Remove; XUNTAG is always a macro now, since it can no longer be implemented as a function. (XUNTAG): New third argument CTYPE. All uses changed. Cast result to CTYPE * instead of using __builtin_assume_aligned. Simplify by using LISP_WORD_TAG. (LISP_WORD_TAG): New macro. (TAG_PTR): Use it. * src/menu.c (x_popup_menu_1): Pacify -Wnull-dereference by using XCAR instead of Fcar and XCDR instead of Fcdr where this is safe.

(read_char): Don't call maybe_reacquire_global_lock here. (handle_interrupt): Call maybe_reacquire_global_lock here, if invoked from the SIGINT handler, to make sure quit_throw_to_read_char runs with main thread's Lisp bindings and uses the main thread's jmp_buf buffer.

* Prefer HTTPS to FTP and HTTP in documentationPaul Eggert2017-09-131-1/+1
| | | | | | | | | | | | | Most of this change is to boilerplate commentary such as license URLs. This change was prompted by ftp://ftp.gnu.org's going-away party, planned for November. Change these FTP URLs to https://ftp.gnu.org instead. Make similar changes for URLs to other organizations moving away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and fsf.org when this works, as this will further help defend against man-in-the-middle attacks (for this part I omitted the MS-DOS and MS-Windows sources and the test tarballs to keep the workload down). HTTPS is not fully working to lists.gnu.org so I left those URLs alone for now.

* Rename primary_thread to main_threadPaul Eggert2016-12-301-1/+1
| | | | | | | | | | | | This avoids the confusion of using two different phrases "main thread" and "primary thread" internally to mean the same thing. See: http://lists.gnu.org/archive/html/emacs-devel/2016-12/msg01142.html * src/thread.c (main_thread): Rename from primary_thread, since the new name no longer clashes with main_thread_id and Emacs internals normally call this the "main thread". (init_main_thread): Rename from init_primary_thread. (main_thread_p): Rename from primary_thread_p. All uses changed.
* regex.h now includes sys/types.hPaul Eggert2016-12-251-1/+0
| | | | | | | * src/dired.c, src/emacs.c, src/search.c, src/syntax.c, src/thread.h: Do not include sys/types.h; no longer needed. * src/regex.h: Include <sys/types.h>, as that's what Gnulib and glibc regex.h does, and POSIX has blessed this since 2008.
* Reorder lisp.h to declare types before using themPaul Eggert2016-12-251-0/+58
| | | | | | | | | | | | | | | | | | | | | | | | | | | This puts basic functions for types to be after the corresponding type definitions. This is a more-common programming style in C, and will make it easier to port Emacs to gcc -fcheck-pointer-bounds, since the functions now have access to the corresponding types' sizes. This patch does not change the code; it just moves declarations and definitions and removes no-longer-needed forward declarations (Bug#25128). * src/buffer.c, src/data.c, src/image.c: Include process.h, for PROCESSP. * src/buffer.h (BUFFERP, CHECK_BUFFER, XBUFFER): * src/process.h (PROCESSP, CHECK_PROCESS, XPROCESS): * src/termhooks.h (TERMINALP, XTERMINAL): * src/window.h (WINDOWP, CHECK_WINDOW, XWINDOW): * src/thread.h (THREADP, CHECK_THREAD, XTHREAD, MUTEXP, CHECK_MUTEX) (XMUTEX, CONDVARP, CHECK_CONDVAR, XCONDVAR): Move here from lisp.h. * src/intervals.h: Include buffer.h, for BUFFERP. Include lisp.h, for Lisp_Object. * src/lisp.h: Reorder declarations and definitions as described above. Move thread includes to be later, so that they can use the reordered definitions. Move some symbols to other headers (noted elsewhere). Remove forward decls that are no longer needed. * src/thread.h: Include systhread.h here, not in lisp.h, since lisp.h itself does not need systhread.h.
* Remove interpreter’s byte stackPaul Eggert2016-12-231-9/+1
| | | | | | | | | | | | | | | | | | | | | This improves performance overall on my benchmark on x86-64, since the interpreted program-counter resides in a machine register rather than in RAM. * etc/DEBUG, src/.gdbinit: Remove xbytecode GDB command, as there is no longer a byte stack to decode. * src/bytecode.c (struct byte_stack, byte_stack_list) (relocate_byte_stack): Remove. All uses removed. (FETCH): Simplify now that pc is now local (typically, in a register) and no longer needs to be relocated. (CHECK_RANGE): Remove. All uses now done inline, in a different way. (BYTE_CODE_QUIT): Remove; now done by op_relative_branch. (exec_byte_code): Allocate a copy of the function’s bytecode, so that there is no problem if GC moves it. * src/lisp.h (struct handler): Remove byte_stack member. All uses removed. * src/thread.c (unmark_threads): Remove. All uses removed. * src/thread.h (struct thread_state): Remove m_byte_stack_list member. All uses removed. m_stack_bottom is now the first non-Lisp field.
