* Avoid undefined behavior in signed left shift.Paul Eggert2014-04-271-1/+2
| | | | | | | | | | | This ports to GCC 4.9.0 with -fsanitize=undefined. * alloc.c (bool_vector_fill, SETMARKBIT, UNSETMARKBIT): * data.c (Fash): * regex.c (extract_number): * lisp.h (make_number, XINT): Do not shift a 1 bit left into a sign bit. * alloc.c (struct cons_block, struct float_block): Use unsigned, not int, for gcmarkbits.

* Avoid undefined behavior with huge regexp interval counts.Paul Eggert2013-12-121-11/+9
| | | | | | | * regex.c (GET_INTERVAL_COUNT): Rename from 'GET_UNSIGNED_NUMBER', since it's now specialized to interval counts. All uses changed. Do not assume wrapraound on signed integer overflow. (regex_compile): Simplify based on the above changes.

* Fix syntax.h bug introduced by recent INLINE change.Paul Eggert2013-09-211-3/+3
| | | | | | | | | | | | | | | | | syntax.h defined an extern inline function SYNTAX_ENTRY that was conditionally compiled one way in some modules, and a different way in others. This doesn't work with extern inline functions, which must have the same definition in all modules, because the defining code might be shared across modules, depending on the implementation. Symptoms reported by Martin Rudalics in: http://lists.gnu.org/archive/html/emacs-devel/2013-09/msg00414.html * regex.c, syntax.c (SYNTAX_ENTRY_VIA_PROPERTY): Remove. (SYNTAX, SYNTAX_ENTRY, SYNTAX_WITH_FLAGS): New macros, overriding the corresponding functions in syntax.h. * syntax.h (syntax_property_entry, syntax_property_with_flags) (syntax_property): New inline functions. (SYNTAX_ENTRY, SYNTAX_WITH_FLAGS, SYNTAX): Rewrite in terms of these new functions.
* * regex.c (CHAR_CHARSET, CHARSET_LEADING_CODE_BASE, CHAR_HEAD_P)Andreas Schwab2013-08-281-16/+15

* Omit some unnecessary casts.Paul Eggert2013-08-101-5/+4

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * lib-src/ebrowse.c (USAGE): Remove macro with too-long string literal ...

(B__dummy__): New dummy symbol, to pacify C89. * src/dbusbind.c (XD_DEBUG_MESSAGE): Omit debugging on C89 hosts, since they can't grok varargs macros. * src/dispnew.c (add_window_display_history) (add_frame_display_history): * src/print.c (print_object): * src/xdisp.c (debug_method_add): Use %p printf format only for void pointers. * src/emacs.c (usage_message): New constant, replacing ... (USAGE1, USAGE2, USAGE3): Remove; they were too long for C89. (main): Adjust to usage reorg. * src/fns.c (syms_of_fns): * src/profiler.c (syms_of_profiler): Don't use non-constant struct initializers. * src/gnutls.h (gnutls_initstage_t): * src/lisp.h (enum Lisp_Fwd_Type): * src/lread.c (lisp_file_lexically_bound_p): * src/xsettings.c (anonymous enum): Remove trailing comma. * src/xsettings.c (apply_xft_settings): Use %f, not %lf; %lf is a C99ism. * src/lisp.h (ENUM_BF): Use unsigned if pedantic. (DEFUN_FUNCTION_INIT): New macro, that falls back on a cast if pre-C99. (DEFUN): Use it. * src/regex.c (const_re_char): New type, to pacify strict C89. All uses of 'const re_char' replaced to use it. * src/regex.h (_Restrict_): Rename from __restrict, to avoid clash with glibc when strict C89. This change is imported from gnulib. All uses changed.

| | | | | | | | | | | | | | | | | | | | | (extract_number, extract_number_and_incr): Define regardless of whether DEBUG is defined; that's simpler and makes the code less likely to go stale in the normal case when DEBUG is not defined. Return int rather than taking an int * arg. All callers changed. (DEBUG_PRINT1, DEBUG_PRINT2, DEBUG_PRINT3, DEBUG_PRINT4): Remove, replacing with ... (DEBUG_PRINT): New macro. All callers changed. (DEBUG_COMPILES_ARGUMENTS): New macro. (print_fastmap, print_partial_compiled_pattern) [DEBUG]: (print_compiled_pattern, print_double_string) [DEBUG]: Use prototype rather than old-style definition.

(POINTER_TO_OFFSET): Return ptrdiff_t, not regoff_t. This matters only when DEBUG is defined.

* Remove configure's --without-sync-input option.Paul Eggert2012-09-161-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When auditing signal-handling in preparation for cleaning it up, I found that SYNC_INPUT has race conditions and would be a real pain to fix. Since it's an undocumented and deprecated configure-time option, now seems like a good time to remove it. Also see <http://bugs.gnu.org/11080#16>. * configure.ac (SYNC_INPUT, BROKEN_SA_RESTART): Remove. * admin/CPP-DEFINES (BROKEN_SA_RESTART, SA_RESTART): Remove. * etc/TODO (Make SYNC_INPUT the default): Remove, as the code now behaves as if SYNC_INPUT is always true. * src/alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal) (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls. (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]: (malloc_hysteresis): (check_depth) [XMALLOC_OVERRUN_CHECK]: (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED) (dont_register_blocks, bytes_used_when_reconsidered) (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc) (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc): [!SYSTEM_MALLOC && !SYNC_INPUT]: Remove. All uses removed. (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different implementation, one that depends on whether the new macro XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT is defined. * src/atimer.c (run_timers, handle_alarm_signal): * src/keyboard.c (pending_signal, poll_for_input_1, poll_for_input) (handle_async_input, process_pending_signals) (handle_input_available_signal, init_keyboard): * src/nsterm.m (ns_read_socket): * src/process.c (wait_reading_process_output): * src/regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK): * src/sysdep.c (emacs_sigaction_init) [SA_RESTART]: (emacs_write): * src/xterm.c (XTread_socket): Assume SYNC_INPUT. * src/conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef. * src/eval.c (handling_signal): Remove.

* Port better to POSIX hosts lacking _setjmp.Paul Eggert2012-09-151-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | * configure.ac (HAVE__SETJMP, HAVE_SIGSETJMP): New symbols. (_setjmp, _longjmp): Remove. * src/lisp.h: Include <setjmp.h> here, since we use its symbols here. All instances of '#include <setjmp.h>' removed, if the only reason for the instance was because "lisp.h" was included. (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols. Unless otherwise specified, replace all uses of jmp_buf, _setjmp, and _longjmp with the new symbols. Emacs already uses _setjmp if available, so this change affects only POSIXish hosts that have sigsetjmp but not _setjmp, such as some versions of Solaris and Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.) * src/image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros. (png_load_body) [HAVE_PNG]: (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]: (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]: Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp, since PNG requires jmp_buf. This is the only exception to the general rule that we now use sys_setjmp and sys_longjmp. This exception is OK since this code does not change the signal mask or longjmp out of a signal handler.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I have been using this change for many months in my private copy of Emacs, and have used it to find several bugs. It's mature enough to publish now. * Makefile.in (GNULIB_MODULES): Add warnings, manywarnings. * configure.in: Support --enable-gcc-warnings, in the style of other GNU packages such as coreutils. (C_WARNINGS_SWITCH): Remove, replacing with... (WARN_CFLAGS, GNULIB_WARN_CFLAGS): New variable. (PKG_CHECK_MODULES, C_SWITCH_X_SITE): Use -isystem rather than -I, when including system files with GCC. * etc/NEWS: Mention --enable-gcc-warnings. * lib/Makefile.am (AM_CFLAGS): New macro. * m4/manywarnings.m4, m4/warnings.m4: New files, from gnulib. * lib-src/Makefile.in (C_WARNINGS_SWITCH): Remove. (WARN_CFLAGS, WERROR_CFLAGS): New macros. (BASE_CFLAGS): Use new macros rather than old. * lwlib/Makefile.in (C_WARNINGS_SWITCH): Remove. (WARN_CFLAGS, WERROR_CFLAGS): New macros. (ALL_CFLAGS): Use new macros rather than old. * oldXMenu/Makefile.in (C_WARNINGS_SWITCH): Remove. (WARN_CFLAGS, WERROR_CFLAGS): New macros. (ALL_CFLAGS): Use new macros rather than old. * src/Makefile.in (C_WARNINGS_SWITCH): Remove. (WARN_CFLAGS, WERROR_CFLAGS): New macros. (ALL_CFLAGS): Use new macros rather than old. * src/process.c: Ignore -Wstrict-overflow to work around GCC bug 52904. * src/regex.c: Ignore -Wstrict-overflow. If !emacs, also ignore -Wunused-but-set-variable, -Wunused-function, -Wunused-macros, -Wunused-result, -Wunused-variable. This should go away once the Emacs and Gnulib regex code is merged. (xmalloc, xrealloc): Now static.

|/ | | | | | | | | | | | | | | | | | | Assume support for memcmp, memcpy, memmove, memset. This simplifies the code a bit. All current platforms have these, as they are required for C89. If this turns into a problem we can add the gnulib modules for these (a 1-line change to Makefile.in). * configure.in: Don't check for memcmp, memcpy, memmove, memset. [lib-src/ChangeLog] Assume support for memcmp, memcpy, memmove, memset. * etags.c (absolute_filename): Assume memmove exists. [src/ChangeLog] Assume support for memcmp, memcpy, memmove, memset. * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset): * regex.c (memcmp, memcpy): Remove; we assume C89 now. * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now. (__malloc_safe_bcopy): Remove; no longer needed.
* Fix regex.c, syntax.c and friends for buffers > 2GB.Eli Zaretskii2011-04-161-67/+74
