* Port better to C23 bool+true+false keywordsPaul Eggert2022-09-281-5/+1
| | | | | | | | | | | | | | | | | | | | C23 is adding the C++ keywords bool, true, and false; prefer them to <stdbool.h> if they are available. * admin/merge-gnulib (GNULIB_MODULES): Add stdbool, which emulates C23 on pre-C23 platforms. (AVOIDED_MODULES): Remove stdbool; Gnulib has renamed this module to stdbool-c99 and nobody uses it so it does not need to be avoided. * m4/c-bool.m4: New file, from Gnulib stdbool module. * lib-src/seccomp-filter.c, src/conf_post.h, src/dynlib.h: * src/emacs-module.c, src/nsterm.m, src/systhread.h: * test/src/emacs-module-resources/mod-test.c: Use the C23 style and use bool without including <stdbool.h>. The Gnulib stdbool module causes config.h to include stdbool.h on pre-C23 platforms. * src/emacs-module.h.in: Don’t include <stdbool.h> if C23 or later, or if it has already been included.
* Use BASE_EQ instead of EQ where obviously safeMattias Engdegård2022-06-161-1/+1

* Do not include <attribute.h> from <config.h>Paul Eggert2022-03-081-10/+9
| | | | | | | | | | | | This is because mod-test.c shouldn’t use source code from lib, but it does need to include <config.h>. * lib-src/ebrowse.c, lib-src/emacsclient.c, lib-src/etags.c: * lib-src/make-docfile.c, lib-src/movemail.c: * lib-src/seccomp-filter.c, src/dynlib.h, src/lisp.h: * src/syssignal.h, src/sysstdio.h, src/systhread.h, src/tparam.h: Include <attribute.h>. * src/conf_post.h: Do not include <attribute.h>.

* Silence macOS vfork deprecation warningsMattias Engdegård2022-02-101-0/+13
| | | | | | | | | | | The vfork system call exists and works in macOS 11.6 but the compiler gives a deprecation message; silence it, because the performance is still better than that of plain fork. See discussion at https://lists.gnu.org/archive/html/emacs-devel/2022-02/msg00260.html * src/conf_post.h (VFORK): New #define. * src/callproc.c (emacs_spawn): * src/sysdep.c (sys_subshell): Use it.

* Port unused decls to C2xPaul Eggert2021-10-031-1/+0
| | | | | * src/conf_post.h (ATTRIBUTE_UNUSED): Remove. All uses replaced by MAYBE_UNUSED, and moved to start as needed for C2x.
* Clean up the fix for unexec build on GNU/LinuxEli Zaretskii2021-05-201-1/+30
| | | | | | | | | | | | | | | * src/conf_post.h [HYBRID_MALLOC || DARWIN_OS && HAVE_UNEXEC]: Include <stdlib.h> here, before redirecting 'malloc' and friends to their hybrid_* and unexec_* equivalents. #undef malloc and friends before redefining. Provide prototypes for the replacements. Suggested by Paul Eggert <eggert@cs.ucla.edu>. * src/gmalloc.c [HYBRID_MALLOC]: Remove declarations of 'malloc' and friends, as they are now redundant: we include <stdlib.h> in conf_post.h before redefining 'malloc' etc., and that provides prototypes from system headers. * configure.ac (HYBRID_MALLOC): Remove kludge to avoid replacement of 'free' by Gnulib. (Bug#36649)

* Fix typos in recent attribute.h simplificationPaul Eggert2020-05-051-4/+5
| | | | | | | | | Problem reported by Andreas Schwab in: https://lists.gnu.org/r/emacs-devel/2020-05/msg00650.html * src/conf_post.h (HAS_ATTR_no_sanitize): Define to false in case cpp is picky, fixing a longstanding glitch here. (ATTRIBUTE_NO_SANITIZE_ADDRESS, ATTRIBUTE_NO_SANITIZE_UNDEFINED): Use HAS_ATTRIBUTE, not __has_attribute.
* Simplify by using attribute.h macrosPaul Eggert2020-05-031-75/+25
| | | | | | | | | | | | | | | | | | attribute.h is partly designed for C2X forward compatibility, since C2X will add some standard attributes. Using its macros should help insulate Emacs from C2X teething problems. * src/conf_post.h: Include attribute.h. (HAS_ATTRIBUTE, HAS_FEATURE): Rename from __has_attribute and __has_feature, to avoid polluting the builtin namespace. All uses changed. (ATTRIBUTE_COLD, ATTRIBUTE_FORMAT, FALLTHROUGH, ATTRIBUTE_CONST) (ATTRIBUTE_PURE, ATTRIBUTE_UNUSED, ATTRIBUTE_MAY_ALIAS) (ATTRIBUTE_MALLOC, ATTRIBUTE_ALLOC_SIZE) (ATTRIBUTE_RETURNS_NONNULL): Remove, as attribute.h does this now. (NO_INLINE, EXTERNALLY_VISIBLE, ARG_NONNULL, ATTRIBUTE_UNUSED): Simplify by defining in terms of attribute.h macros. * src/systhread.h (ATTRIBUTE_WARN_UNUSED_RESULT): Remove. All uses replaced by attribute.h’s NODISCARD.
* Prefer inline functions in character.hPaul Eggert2020-04-171-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | In character.h, replace macros with inline functions or enums when this is easy. This improves maintainability and on my platform (Fedora 31 x86-64, gcc -O2) improved CPU performance very slightly (0.3%) on ‘make compile-always’. * src/buffer.h (SANE_TAB_WIDTH, CHARACTER_WIDTH): Move here from character.h, and make them inline functions. Tune CHARACTER_WIDTH so that ASCII_CHAR_WIDTH is no longer needed. (sanitize_tab_width, sanitize_char_width): Move here from character.h. * src/character.h (MAX_CHAR, MAX_UNICODE_CHAR, MAX_1_BYTE_CHAR) (MAX_2_BYTE_CHAR, MAX_3_BYTE_CHAR, MAX_4_BYTE_CHAR) (MAX_5_BYTE_CHAR, MIN_MULTIBYTE_LEADING_CODE) (MAX_MULTIBYTE_LEADING_CODE, MAX_MULTIBYTE_LENGTH): Now enum constants instead of macros. * src/character.h (CHAR_BYTES): Redo to avoid conditional branches. (CHAR_BYTE8_P, BYTE8_TO_CHAR, UNIBYTE_TO_CHAR, CHAR_TO_BYTE8) (CHAR_TO_BYTE_SAFE, CHAR_BYTE8_HEAD_P, CHARACTERP) (CHECK_CHARACTER, CHECK_CHARACTER_CAR, CHECK_CHARACTER_CDR) (CHAR_PRINTABLE_P, CHAR_BYTES, CHAR_LEADING_CODE, BYTE8_STRING) (LEADING_CODE_P, TRAILING_CODE_P, CHAR_HEAD_P) (BYTES_BY_CHAR_HEAD): Now inline functions instead of macros. (ASCII_CHAR_WIDTH): Remove; no longer used. * src/conf_post.h (ATTRIBUTE_PURE): New macro. * src/lisp.h (char_table_ref): Use it, for better inlining. * src/fns.c (base64_decode_1): Add now-necessary casts.
* Improve inlining when compiling with -OgPaul Eggert2020-04-071-5/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | * src/conf_post.h (EXTERN_INLINE) [!EMACS_EXTERN_INLINE]: Make it static inline, not merely static. This is a worthwhile performance improvement on my two platforms A and B (see below). On my platform A this change improves user+system CPU performance of ‘make compile-always’ by 52% on an -Og build, and by 1.4% on the default -O2 build. On my platform B this improves the same benchmark by 41% on an -Og build, and by -0.8% on the default -O2 build. That "-0.8%" is a small negative for this change, and I recall that it is why I didn't make this change earlier. However, Platform B uses an older GCC so we needn't worry overmuch about this small negative. With this change the performance advantage of -O2 over -Og has dropped on platform A; formerly -O2 was 87% faster than -Og, and now it is only 25% faster. On platform B the performance advantage of -O2 over -Og has dropped from being 62% faster to being 14% faster. Platform A is GCC 9.3.1 20200317 (Red Hat 9.3.1-1) on Fedora 31 x86-64 (AMD Phenom II X4 910e, circa 2010). Platform B is GCC (Ubuntu 7.5.0-3ubuntu1~18.04) 7.5.0 on Ubuntu 18.04.4 (Intel Xeon E3-1225 V2, circa 2012). This patch was inspired by a suggestion by Andrea Corallo in: https://lists.gnu.org/r/emacs-devel/2020-04/msg00263.html
* Pacify GCC 9.2.1 20190927 -O3Paul Eggert2020-03-041-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | Original problem report by N. Jackson in: https://lists.gnu.org/r/emacs-devel/2020-03/msg00047.html I found some other warnings when I used gcc, and fixed them with this patch. * lib-src/etags.c: Include verify.h. (xnmalloc, xnrealloc): Tell the compiler that NITEMS is nononnegative and ITEM_SIZE is positive. * src/conf_post.h (__has_attribute_returns_nonnull) (ATTRIBUTE_RETURNS_NONNULL): New macros. * src/editfns.c (Fuser_full_name): Don’t assume Fuser_login_name returns non-nil. * src/intervals.c (rotate_right, rotate_left, update_interval): * src/intervals.h (LENGTH, LEFT_TOTAL_LENGTH, RIGHT_TOTAL_LENGTH): Use TOTAL_LENGTH0 or equivalent on intervals that might be null. * src/intervals.h (TOTAL_LENGTH): Assume arg is nonnull. (TOTAL_LENGTH0): New macro, with the old TOTAL_LENGTH meaning. (make_interval, split_interval_right): Add ATTRIBUTE_RETURNS_NONNULL. * src/pdumper.c (dump_check_dump_off): Now returns void, since no caller uses the return value. Redo assert to pacify GCC. (decode_emacs_reloc): Add a seemingly-random eassume to pacify GCC. Ugly, and I suspect due to a bug in GCC.

* Use plain ‘static’ for Emacs C inline functionsPaul Eggert2019-09-041-9/+34
| | | | | | | This improved performance of ‘make compile-always’ by 8.2% on my platform (AMD Phenom II X4 910e, Fedora 30 x86-64). * src/conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN) (INLINE_HEADER_END) [!EMACS_EXTERN_INLINE]: Use plain ‘static’.

* | Modularize bignums betterPaul Eggert2018-08-271-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * src/bignum.c, src/bignum.h: New files. Only modules that need to know how bignums are implemented should include bignum.h. Currently these are alloc.c, bignum.c (of course), data.c, emacs.c, emacs-module.c, floatfns.c, fns.c, print.c. * src/Makefile.in (base_obj): Add bignum.o. * src/alloc.c (make_bignum_str): Move to bignum.c. (make_number): Remove; replaced by bignum.c’s make_integer. All callers changed. * src/conf_post.h (ARG_NONNULL): New macro. * src/json.c (json_to_lisp): Use it. * src/data.c (Fnatnump): Move NATNUMP’s implementation here from lisp.h. * src/data.c (Fnumber_to_string): * src/editfns.c (styled_format): Move conversion of string to bignum to bignum_to_string, and call it here. * src/emacs-module.c (module_make_integer): * src/floatfns.c (Fabs): Simplify by using make_int. * src/emacs.c: Include bignum.h, to expand its inline fns. * src/floatfns.c (Ffloat): Simplify by using XFLOATINT. (rounding_driver): Simplify by using double_to_bignum. (rounddiv_q): Clarify use of temporaries. * src/lisp.h: Move decls that need to know bignum internals to bignum.h. Do not include gmp.h or mini-gmp.h; that is now bignum.h’s job. (GMP_NUM_BITS, struct Lisp_Bignum, XBIGNUM, mpz_set_intmax): Move to bignum.h. (make_int): New function. (NATNUMP): Remove; all callers changed to use Fnatnump. (XFLOATINT): If arg is a bignum, use bignum_to_double, so that bignum internals are not exposed here. * src/print.c (print_vectorlike): Use SAFE_ALLOCA to avoid the need for a record_unwind_protect_ptr.
* | Make mini-gmp safe for --enable-gcc-warningsPaul Eggert2018-08-121-2/+9
| | | | | | | | | | | | | | | | | | | | * configure.ac (GMP_OBJ): When building mini-gmp, compile mini-gmp-emacs.c, not mini-gmp.c. * lib-src/etags.c (NDEBUG): Don't attempt to redefine, in case the builder compiles with -DNDEBUG. * src/conf_post.h (NDEBUG) [!ENABLE_CHECKING && !NDEBUG]: Define. This avoids bloat in mini-gmp-emacs.o. * src/mini-gmp-emacs.c: New file, which pacifies --enable-gcc-warnings.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * src/json.c, src/keyboard.c, src/keyboard.h, src/keymap.c, src/kqueue.c, src/lcms.c, src/lisp.h, src/lread.c, src/macros.c, src/marker.c, src/menu.c, src/minibuf.c, src/msdos.c, src/print.c, src/process.c, src/profiler.c, src/search.c, src/sound.c, src/syntax.c, src/sysdep.c, src/term.c, src/terminal.c, src/textprop.c, src/undo.c, src/w16select.c, src/w32.c, src/w32console.c, src/w32cygwinx.c, src/w32fns.c, src/w32font.c, src/w32inevt.c, src/w32proc.c, src/w32select.c, src/w32term.c, src/w32uniscribe.c, src/widget.c, src/window.c, src/xdisp.c, src/xfaces.c, src/xfns.c, src/xfont.c, src/xftfont.c, src/xmenu.c, src/xrdb.c, src/xselect.c, src/xterm.c, src/xwidget.c: Rename INTEGERP->FIXNUM, make_number->make_fixnum, CHECK_NUMBER->CHECK_FIXNUM, make_natnum->make_fixed_natum, NUMBERP->FIXED_OR_FLOATP, NATNUMP->FIXNATP, CHECK_NATNUM->CHECK_FIXNAT.
* | Use native alignment to access Lisp object dataPaul Eggert2018-06-101-13/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* | Remove AddressSanitizer bug workaroundPaul Eggert2018-06-081-1/+2
| | | | | | | | | | | | | | | | | | This workaround no longer appears to be needed. * src/alloc.c (USE_ALIGNED_ALLOC): Don’t leave undefined merely because ADDRESS_SANITIZER is defined, as that bug in -fsanitize=address appears to have been fixed. See: https://github.com/google/sanitizers/issues/337 * src/conf_post.h (vfork): Improve comment.
* | Port to GCC 8 -fsanitize=undefinedPaul Eggert2018-05-181-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | In GCC 8, gcc -fsanitize=undefined flags the undefined behavior that Emacs relies on in its XPNTR and XSYMBOL low-level functions. Disable undefined sanitization in these functions. Although this disabling doesn’t suffice if DEFINE_KEY_OPS_AS_MACROS is true, it works for -fsanitize=undefined -DINLINING=0, which is good enough. * src/alloc.c (macro_PNTR_ADD): New macro. (PNTR_ADD): New function and macro. The function disables -fsanitize=undefined. (macro_XPNTR): Use it. * src/conf_post.h (ATTRIBUTE_NO_SANITIZE_UNDEFINED): New macro. * src/lisp.h (XSYMBOL): Disable -fsanitize=undefined.
* | Pacify GCC when --enable-profilingPaul Eggert2018-04-031-0/+4
|/ | | | | | | * src/conf_post.h (PROFILING): Undef if not on a platform that supports it. Simplify uses accordingly. * src/emacs.c (etext) [PROFILING]: Declare at top level to avoid GCC warning.

(LIBRESOLV, DEPFLAGS, MKDEPDIR, YMF_PASS_LDFLAGS) (PRE_EDIT_LDFLAGS, POST_EDIT_LDFLAGS): Remove editing. Remove editing of lines that are no longer present in src/Makefile.in. * msdos/sed2v2.inp (NEED_MKTIME_INTERNAL) (NEED_MKTIME_WORKING): Define to 1. (HAVE_STRUCT_DIRENT_D_TYPE): Define to 1 for DJGPP >= 2.05. (HAVE_STRUCT_ATTRIBUTE_ALIGNED): Define to 1. Define PACKAGE_VERSION, not VERSION. (FLEXIBLE_ARRAY_MEMBER): Define to empty. (HAVE_DECL_*_UNLOCKED): Define to 0. (HAVE___BUILTIN_FRAME_ADDRESS): Define to 1. (PENDING_*): Don't define, as Gnulib no longer supports that. Instead, define _IOERR as it is in libc/file.h. * msdos/sed3v2.inp: Use $(CURDIR) instead of $(shell cd) to determine the current directory. (UPDATE_MANIFEST, UTILITIES): Don't edit. * msdos/sedlisp.inp (FIND_DELETE): Edit to "-delete". * msdos/sedlibmk.inp (AUTO_DEPEND): Define to yes. (HYBRID_MALLOC): Edit to empty. (am__cd): Don't edit. (../config.status): Replaces $(top_builddir)/config.status. Define OMIT_GNULIB_MODULE_foo = true for modules not built for MS-DOS. Convert GL_GENERATE_xxx_H_TRUE and GL_GENERATE_xxx_H_FALSE into values of GL_GENERATE_xxx_H. * msdos/mainmake.v2 (src): Use 'compile-one-process', and make the command line shorter to fit into 126-char limit of command.com. * config.bat: Generate src/deps/*.d files. Rename more files like djtar on plain DOS would. Don't rename src/dir.h: it is long gone. Edit lib/gnulib.mk.in using the same scripts as for lib/Makefile.in. * msdos/depfiles.bat: Create *.d files, not *.Po. * src/thread.c (Fmake_thread) [!THREADS_ENABLED]: Improve the error message. * src/thread.h [MSDOS]: Include <signal.h>. * src/sysselect.h (select) [MSDOS]: Undefine, to avoid compilation errors. * src/sysdep.c (block_interrupt_signal, restore_signal_mask): Expose to MSDOS build. * src/process.c (update_processes_for_thread_death) [!subprocess]: No-op implementation. [HAVE_SETRLIMIT]: Move inclusion of sys/resource.h and declaration of nofile_limit outside "#ifdef subprocesses", as it's needed for MSDOS. * src/msdos.c (faccessat): Declare fullname[]. * src/msdos.h (ENOTSUP): Define to be identical to ENOSYS. Include termhooks.h. * src/conf_post.h [WINDOWSNT]: Include ms-w32.h only on WINDOWSNT, not DOS_NT. * admin/admin.el (set-version): Set version on PACKAGE_VERSION.
* Fix warnings about formats in printf-like functions on MS-WindowsEli Zaretskii2017-09-141-1/+21
| | | | | | | | | | | * src/lisp.h (pI) [__MINGW32__]: Provide definition that will hopefully DTRT with both MinGW64 and mingw.org's MinGW. See http://lists.gnu.org/archive/html/emacs-devel/2017-09/msg00171.html for the details. * src/conf_post.h (PRINTF_ARCHETYPE) [MINGW_W64]: Separate definition specific to MinGW64. (PRINTF_ARCHETYPE) [__MINGW32__]: For mingw.org's MinGW, use __mingw_printf__ in ANSI-compatible mode.
* 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.
* Port cleanup check to Oracle Studio 12.5Paul Eggert2017-06-141-1/+4
| | | | | | * src/conf_post.h (__has_attribute_cleanup): Resurrect. * src/emacs-module.c: Verify __has_attribute (cleanup), but in an #if this time.
* Port cleanup attribute to Oracle Studio 12.5Paul Eggert2017-06-131-1/+0
| | | | | | | | | | | * INSTALL (--with-modules): List cleanup attribute as prereq. * src/conf_post.h (__has_attribute_cleanup): Remove; no longer needed. * src/emacs-module.c (MODULE_SETJMP_1): Don’t attempt to verify (__has_attribute (cleanup)), as Oracle Studio 12.5 supports __has_attribute only inside preprocessor expressions. The C compiler should check the cleanup attribute in the next line anyway. (module_reset_handlerlist): Remove an unnecessary ‘const’ that causes Oracle Studio 12.5 to refuse to compile.
* Port ATTRIBUTE_MAY_ALIAS to recent iccPaul Eggert2017-05-251-1/+1
| | | | | | | | | * src/conf_post.h (ATTRIBUTE_MAY_ALIAS) [__ICC]: Define to empty. Otherwise, icc (ICC) 17.0.4 20170411 says “warning #2621: attribute "__may_alias__" does not apply here” for constructs like ‘struct sockaddr *sa = (whatever); struct sockaddr_in __attribute__ ((__may_alias__)) *sin = (struct sockaddr_in *) sa;’.
* Avoid undefined behavior in struct sockaddrPaul Eggert2017-05-171-0/+14
| | | | | | | | | | Problem noted by Philipp Stephani in: http://lists.gnu.org/archive/html/emacs-devel/2017-05/msg00391.html * src/conf_post.h (ATTRIBUTE_MAY_ALIAS, DECLARE_POINTER_ALIAS): New macros. * src/process.c (conv_sockaddr_to_lisp, conv_lisp_to_sockaddr) (connect_network_socket, network_interface_info) (server_accept_connection): Use it when aliasing non-char objects.
* Work around AddressSanitizer bug with vforkPaul Eggert2017-05-171-0/+6
| | | | | | | | | | Problem reported by Jim Meyering in: http://lists.gnu.org/archive/html/emacs-devel/2017-05/msg00246.html * src/conf_post.h (vfork) [ADDRESS_SANITIZER]: Define to fork. Unfortunately with the AddressSanitizer in Fedora 25 x86-64, the vforked child messes up the parent’s shadow memory. This is too bad, as we’d rather have AddressSanitizer catch memory-access bugs related to vfork.
