* Limit <config.h>’s includesPaul Eggert2016-09-301-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This follows up on recent problems with the fact that config.h includes stdlib.h etc.; some files need to include stdlib.h later. config.h generally should limit itself to includes that are universally safe; outside of MS-Windows, only stdbool.h makes the cut among the files currently included. So, move the other includes to just the files that need them (Bug#24506). * configure.ac (config_opsysfile): Remove, as this generic hook is no longer needed. * lib-src/etags.c, src/unexmacosx.c, src/w32.c, src/w32notify.c: * src/w32proc.c (_GNU_SOURCE): Remove, as it’s OK for config.h to do this now. * src/conf_post.h: Include <ms-w32.h>, instead of the generic config_opsysfile, for simplicity as this old way of configuring is now done only for the MS-Windows port. Do not include <ms-w32.h> if DEFER_MS_W32_H, for the benefit of the few files that want its effects later. Do not include <alloca.h>, <string.h>, or <stdlib.h>. Other files modified to include these headers as needed, or to not include headers that are no longer needed. * src/lisp.h: Include <alloca.h> and <string.h> here, since some of the inline functions need them. * src/regex.c: Include <alloca.h> if not emacs. (If emacs, we can rely on SAFE_ALLOCA.) There is no longer any need to worry about HAVE_ALLOCA_H. * src/unexmacosx.c: Rely on config.h not including stdlib.h. * src/w32.c, src/w32notify.c, src/w32proc.c (DEFER_MS_W32_H): Define before including <config.h> first, and include <ms-w32.h> after the troublesome headers.
* Prefer now-standard int width macrosPaul Eggert2016-09-151-14/+10
| | | | | | | | | | | | | | | | | | | | | * src/data.c (ULL_WIDTH): * src/lisp.h (EMACS_INT_WIDTH, BITS_PER_BITS_WORD): * src/lread.c (read_integer): * src/term.c (produce_glyphless_glyph): * src/xterm.c (x_send_scroll_bar_event): Use *_WIDTH macros instead of CHAR_BIT * sizeof. * src/data.c (ULL_WIDTH): Rename from BITS_PER_ULL for consistency with the *_WIDTH standard macros. All uses changed. * src/gmalloc.c (INT_BIT): Remove. All uses replaced with INT_WIDTH. * src/lisp.h (EMACS_INT_WIDTH): Rename from BITS_PER_EMACS_INT for consistency with the *_WIDTH standard macros. All uses changed. (BITS_PER_CHAR): Remove; all uses replaced by CHAR_BIT. This must be the same as CHAR_WIDTH and avoids confusion with Elisp char-width, which counts columns not bits. (BITS_PER_SHORT): Remove; all uses replaced by SHRT_WIDTH. (BITS_PER_LONG): Remove; all uses replaced by LONG_WIDTH. * src/lread.c: Do not include limits.h since CHAR_BIT is no longer used directly.
* Avoid aborts in GC due to abort_on_gcEli Zaretskii2016-09-141-1/+0
| | | | | | | | | * src/lisp.h: * src/print.c (Fprin1_to_string): * src/eval.c (signal_or_quit): * src/alloc.c (garbage_collect_1): Remove declarations, setting, and testing the value of abort_on_gc. It is no longer needed, and using it causes rare aborts in GC for no good reason. (Bug#23912)
* Port flexible array members to GCC + valgrindPaul Eggert2016-09-071-7/+0
| | | | | | | | | | | | | | | | | | | | | | | | | These changes are needed to conform to the C standard's rule for allocating structs containing flexible array members. C11 says that malloc (offsetof (struct s, m) + n) does not suffice to allocate a struct with an n-byte tail; instead, malloc’s arg should be rounded up to the nearest multiple of alignof (struct s). Although this is arguably a defect in C11, gcc -O2 + valgrind sometimes complains when this rule is violated, and when debugging it’s better to keep valgrind happy. For details please see the thread containing the message at: https://gcc.gnu.org/ml/gcc-patches/2016-09/msg00416.html * lib-src/ebrowse.c, src/alloc.c, src/image.c, src/process.c: Include flexmember.h. * lib-src/ebrowse.c (add_sym, add_member, make_namespace) (register_namespace_alias): * src/alloc.c (SDATA_SIZE, allocate_string_data): * src/image.c (xpm_cache_color, imagemagick_create_cache): * src/process.c (Fmake_network_process): Use FLEXSIZEOF instead of offsetof and addition. * src/alloc.c (SDATA_SIZE, vector_alignment): Use FLEXALIGNOF instead of sizeof (ptrdiff_t). * src/lisp.h (ALIGNOF_STRUCT_LISP_VECTOR): Remove, as alloc.c can now calculate this on its own.
* Remove interpreter’s byte stackPaul Eggert2016-08-091-5/+8
| | | | | | | | | | | | | | | | | | | | | 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. (SAFE_ALLOCA_LISP_EXTRA): New macro, a generalization of SAFE_ALLOCA_LISP. (SAFE_ALLOCA_LISP): Use it.

| * Adjust match data before calling after-change-funsNoam Postavsky2016-07-221-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's important to adjust the match data in between calling before-change-functions and after-change-functions, so that buffer change hooks will always see match-data consistent with buffer content. (Bug #23917) * src/insdel.c (replace_range): Add new parameter ADJUST_MATCH_DATA, if true call update_search_regs. Update all callers (except Freplace_match) to pass 0 for the new parameter. * src/search.c (update_search_regs): New function, extracted from Freplace_match. (Freplace_match): Remove match data adjustment code, pass 1 for ADJUST_MATCH_DATA to replace_range instead.
* | ‘signal’ no longer returnsPaul Eggert2016-07-251-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Although for decades ‘signal’ has been documented to not return, a corner case in the Lisp debugger causes ‘signal’ to return. Remove the corner case and adjust Emacs internals accordingly. An alternative would be to document the corner case, but this would complicate the Lisp API unnecessarily. (Bug#24047) * src/eval.c (signal_or_quit): New function, with most of the old contents of Fsignal. (quit): New function, which uses signal_or_quit and which might return. All keyboard-based callers of Fsignal (Qquit, Qnil) changed to use this new function instead. (Fsignal): Use signal_or_quit. Now _Noreturn. All callers changed. (xsignal): Move to lisp.h. * src/lisp.h (xsignal): Now an inline function, as it's now just an alias for Fsignal.
* | Fix port to glibc 2.24 (pre-release) + ppc64Paul Eggert2016-07-201-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | * src/callproc.c (child_setup): Use emacs_exec_file so that ASLR is enabled in the child process. * src/emacs.c: Move some personality details into sys/sysdep.c. Do not include <sys/personality.h>. (main): Disable ASLR earlier, so that we don’t chdir twice. * src/lisp.h (disable_address_randomization): New decl. * src/sysdep.c (disable_address_randomization) [HAVE_PERSONALITY_ADDR_NO_RANDOMIZE]: Move personality details here from emacs.c. (emacs_exec_file): New function.
* | Fix 'transpose-regions' when LEAVE-MARKERS arg is non-nilEli Zaretskii2016-07-191-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | * src/insdel.c (adjust_markers_bytepos): New function. * src/lisp.h (adjust_markers_bytepos): Add prototype. * src/insdel.c (replace_range, replace_range_2): * src/editfns.c (Ftranspose_regions): Call adjust_markers_bytepos. (Bug#5131) * test/src/editfns-tests.el (transpose-test-reverse-word) (transpose-test-get-byte-positions): New functions.

(FACE_SUITABLE_FOR_ASCII_CHAR_P, FACE_FOR_CHAR): Now inline functions instead of macros. This avoids the need for all those casts to void. (FACE_SUITABLE_FOR_ASCII_CHAR_P): Omit 2nd (unused) arg. All uses changed. * src/frame.c (Ficonify_frame, Fset_frame_position): * src/xdisp.c (Fmove_point_visually, show_mouse_face): * src/xdisp.c (note_mode_line_or_margin_highlight) (note_mouse_highlight): Assume HAVE_WINDOW_SYSTEM for simplicity, since the code should now work either way without generating warnings. * src/frame.c (display_available) [HAVE_WINDOW_SYSTEM]: New function. (window_system_available) [HAVE_WINDOW_SYSTEM]: Move to frame.h. (decode_window_system_frame): Use check_window_system instead of rolling the code ourself. Return needed only if HAVE_WINDOW_SYSTEM. (decode_window_system_frame, check_window_system): Merge the HAVE_WINDOW_SYSTEM and !HAVE_WINDOW_SYSTEM versions into one. * src/frame.c (Ficonify_frame, Fset_frame_position): * src/xdisp.c (show_mouse_face, define_frame_cursor1) (note_mouse_highlight): Narrow the scope of the HAVE_WINDOW_SYSTEM #ifdef; this is a better way to pacify GCC. * src/xdisp.c (x_set_left_fringe, x_set_right_fringe) (x_set_right_divider_width, x_set_bottom_divider_width): * src/xfns.c (x_set_internal_border_width): Don’t use what are now function calls as lvalues. * src/frame.h (WINDOW_SYSTEM_RETURN): New macro. (decode_window_system_frame, check_window_system): Use it, to avoid the need for duplicate declarations. (window_system_available): Now an inline function. (display_available): New decl. (frame_dimension): New inline function. (FRAME_FRINGE_COLS, FRAME_LEFT_FRINGE_WIDTH) (FRAME_RIGHT_FRINGE_WIDTH, FRAME_TOTAL_FRINGE_WIDTH) (FRAME_INTERNAL_BORDER_WIDTH, FRAME_RIGHT_DIVIDER_WIDTH) (FRAME_BOTTOM_DIVIDER_WIDTH): Use it, to avoid the need for duplicate definitions. Now inline functions instead of macros. * src/gnutls.c (gnutls_log_function2i): Remove. * src/gnutls.h (GNUTLS_LOG2i): Use ‘message’ directly. This avoids complaints about gnutls_log_function2i being defined and not used on older platforms that do not need to call GNUTLS_LOG2i. * src/image.c (DefaultDepthOfScreen) [0]: Remove unused macro. * src/lisp.h (AUTO_STRING_WITH_LEN): Revert change from ‘type id = expr’ to ‘type id; id = expr’, as this would suppress valid jump-misses-init diagnostics. Let’s find a better way to address the problem. * src/vm-limit.c (__MALLOC_HOOK_VOLATILE): Define only if needed. * src/xdisp.c (handle_single_display_spec): Simplify fringe_bitmap computation. (define_frame_cursor1): Do nothing unless in a window system. All callers changed and simplified. * src/xfaces.c (realize_default_face): Use a simpler way to pacify GCC when a return value is not used on some platforms.

(x_create_bitmap_from_data): Declare 'frame'. (x_create_bitmap_from_file): Don't declare unused variable 'dpyinfo'. * src/lisp.h (AUTO_STRING_WITH_LEN): Avoid initialization to prevent "jump-misses-init" compiler warnings. * src/w32fns.c (check_w32_winkey_state): Define and use only if WINDOWSNT. (Fx_show_tip): Declare 'f'. (Fx_file_dialog): Declare 'filter_a' only if not NTGUI_UNICODE. (w32_strerror): Use format specifier %d for sprintf argument of type int. (emacs_abort): Cast sprintf argument of type DWORD to unsigned int, and use format specifier %x, for compatibility with Cygwin. (unicode_append_menu) [NTGUI_UNICODE]: * src/w32menu.c [NTGUI_UNICODE] (get_menu_item_info) (set_menu_item_info, unicode_append_menu) (unicode_message_box): * src/menu.c [NTGUI_UNICODE] (unicode_append_menu): Define as functions rather than macros to avoid "address will always evaluate as true" compiler warnings. * src/w32font.c (w32_to_x_charset): Use format specifier %d for sprintf argument of type int. * src/w32term.c (x_draw_glyphless_glyph_string_foreground): Cast sprintf argument of type int to unsigned int to match %X format specifier. (w32_scroll_bar_handle_click): (w32_horizontal_scroll_bar_handle_click): Declare 'f'. * src/w32term.h (FRAME_DISPLAY_INFO): Explicitly discard unused argument.
* | Port to platforms where char * has top bit setPaul Eggert2016-06-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a five-year-old FIXME comment. Although I don’t know of a platform where this is a problem in practice, better safe than sorry. * src/doc.c (Fdocumentation): If SUBRP, simply use doc as integer, as it is now an integer, not char *. (store_function_docstring): Offset is now EMACS_INT, not ptrdiff_t; this is a file offset and EMACS_INT is better if --with-wide-int. If SUBRP, simply store the offset rather than negating it and converting it to char *. * src/lisp.h (struct Lisp_Subr.doc): Now EMACS_INT, not char *.
* | New macro GNUC_PREREQ for GCC versionPaul Eggert2016-06-121-4/+3
| | | | | | | | | | | | | | | | | | | | * src/conf_post.h (GNUC_PREREQ): New macro. Change uses of __GNUC_MINOR__ and __GNUC_PATCHLEVEL__ to use this macro instead, for clarity and consistency. (PRINTF_ARCHETYPE): New macro. Define it to __gnu_printf__ only if glibc, since non-GNU platforms don’t necessarily support GNU printf formats. (ATTRIBUTE_FORMAT_PRINTF): Use it.
* | Fix printf-related compilation warnings on MinGWEli Zaretskii2016-06-121-1/+5
| | | | | | | | | | | | | | | | * src/conf_post.h (ATTRIBUTE_FORMAT_PRINTF) [__MINGW32__]: Use '__ms_printf__', not '__gnu_printf__', as the latter is not what MS 'printf' supports, and causes bogus compilation warnings. * src/lisp.h (pI) [__MINGW32__]: Define to "I64", as MS 'printf' doesn't support the "ll" modifier.
* | emacs_strerror cleanupsPaul Eggert2016-06-111-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * src/buffer.c, src/emacs.c, src/lread.c: Don’t include coding.h; no longer needed, now that emacs_strerror is declared by lisp.h. * src/coding.c (emacs_strerror): Remove; moved to emacs.c. * src/coding.h (emacs_strerror) [emacs]: Remove decl; moved to lisp.h. * src/emacs.c (emacs_strerror): Move here from coding.c. Do not convert result string; this is now the caller’s responsibility, as some need conversion and others don’t. * src/fileio.c (report_file_errno, report_file_notify_error): Use emacs_strerror rather than rolling it ourselves. * src/lisp.h (emacs_strerror): Move decl here from coding.h. * src/lread.c (dir_warning): Just call emacs_strerror rather than both strerror and emacs_strerror. Convert its result from locale-coding-system, since it no longer does that conversion. * src/sound.c (sound_perror): * src/sysdep.c (emacs_perror, str_collate): Use emacs_strerror, not strerror.
* | Use __builtin_assume_aligned on untagged Lisp valsPaul Eggert2016-06-071-1/+3
| | | | | | | | | | | | | | | | * src/conf_post.h (__has_builtin, __builtin_assume_aligned): New macros, for compilers not already defining them. (__has_builtin___builtin_assume_aligned): New macro. * src/lisp.h (lisp_h_XUNTAG): Use __builtin_assume_aligned. This shrinks text space by 0.2% on x86-64 with GCC 6.1.

| | | | | | | | | | | | | | | | Work around Bug#22884 by rewording comments and strings to avoid ‘(’ at the start of a line unless it starts a function. This change is a short-term hack; in the longer run we plan to fix cc-mode’s performance for C files that have ‘(’ at the start of a line in a comment or string.
