      Prefer more inline functions in character.h · 27d10183
      Paul Eggert authored
      * src/buffer.h (fetch_char_advance, fetch_char_advance_no_check)
      (buf_next_char_len, next_char_len, buf_prev_char_len)
      (prev_char_len, inc_both, dec_both): New inline functions,
      replacing the old character.h macros FETCH_CHAR_ADVANCE,
      FETCH_CHAR_ADVANCE_NO_CHECK, BUF_INC_POS, INC_POS, BUF_DEC_POS,
      DEC_POS, INC_BOTH, DEC_BOTH respectively.  All callers changed.
      These new functions all assume buffer primitives and so need
      to be here rather than in character.h.
      * src/casefiddle.c (make_char_unibyte): New static function,
      replacing the old MAKE_CHAR_UNIBYTE macro.  All callers changed.
      (do_casify_unibyte_string): Use SINGLE_BYTE_CHAR_P instead
      of open-coding it.
      * src/ccl.c (GET_TRANSLATION_TABLE): New static function,
      replacing the old macro of the same name.
      * src/character.c (string_char): Omit 2nd arg.  3rd arg can no
      longer be NULL.  All callers changed.
      * src/character.h (SINGLE_BYTE_CHAR_P): Move up.
      (MAKE_CHAR_UNIBYTE, MAKE_CHAR_MULTIBYTE, PREV_CHAR_BOUNDARY)
      (STRING_CHAR_AND_LENGTH, STRING_CHAR_ADVANCE)

      (FETCH_STRING_CHAR_ADVANCE_NO_CHECK, FETCH_CHAR_ADVANCE)
      (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, INC_BOTH)
      (DEC_BOTH, BUF_INC_POS, BUF_DEC_POS): Remove.
      (make_char_multibyte): New static function, replacing
      the old macro MAKE_CHAR_MULTIBYTE.  All callers changed.
      (CHAR_STRING_ADVANCE): Remove; all callers changed to use
      CHAR_STRING.
      (NEXT_CHAR_BOUNDARY): Remove; it was unused.
      (raw_prev_char_len): New inline function, replacing the
      old PREV_CHAR_BOUNDARY macro.  All callers changed.
      (string_char_and_length): New inline function, replacing the
      old STRING_CHAR_AND_LENGTH macro.  All callers changed.
      (STRING_CHAR): Rewrite in terms of string_char_and_length.
      (string_char_advance): New inline function, replacing the old
      STRING_CHAR_ADVANCE macro.  All callers changed.
      (fetch_string_char_advance): New inline function, replacing the
      old FETCH_STRING_CHAR_ADVANCE macro.  All callers changed.
      (fetch_string_char_as_multibyte_advance): New inline function,
      replacing the old FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE macro.
      All callers changed.
      (fetch_string_char_advance_no_check): New inline function,
      replacing the old FETCH_STRING_CHAR_ADVANCE_NO_CHECK macro.  All
      callers changed.
      * src/regex-emacs.c (HEAD_ADDR_VSTRING): Remove; no longer used.
      * src/syntax.c (scan_lists): Use dec_bytepos instead of
      open-coding it.
      * src/xdisp.c (string_char_and_length): Rename from
      string_char_and_length to avoid name conflict with new function in
      character.h.  All callers changed.

      Do not alter match data in Fcapitalize etc. · 412139f1
      Paul Eggert authored
      Without this patch, (capitalize "x") can alter the match data,
      which is not what users expect.  Problem found by running
      morse-tests-unnato-region in a stripped-down Emacs.
      Perhaps ‘load’ should also save and restore the match data?
      That would be a simpler fix, though arguably incompatible.
      * src/lread.c (save_match_data_load): New function.

      Prefer HTTPS to FTP and HTTP in documentation · bc511a64
      Paul Eggert authored
      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.

      Rework C source files to avoid ^( · 7352c6c6
      Paul Eggert authored
      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.

      Omit unnecessary \ before paren in C docstrings · 032ce1c7
      Paul Eggert authored
      Although \( is needed in docstrings in Elisp code, it is not needed in
      docstrings in C code, since C function definitiions do not start with
      a parenthesis.  The backslashes made the docstrings a bit harder to
      read and to format in columns.  Also, some C docstrings had ( in
      column 1 and this did not appear to be causing any problems.  So,
      simplify C docstrings by replacing \( with ( and \) with ).

      Simplify stack-allocated Lisp objects, and make them more portable. · dc452569
      Paul Eggert authored
      The build_local_string macro was used in two ways: (1) string
      literals for which scoped allocation suffices, and (2) file name
      components, where it's not safe in general to assume bounded-size
      ASCII data.  Simplify by defining a new macro SCOPED_STRING that
      allocates a block-scope string, and by using SCOPED_STRING for (1)
      and build_string for (2).  Furthermore, actually use stack
      allocation only for objects known to have sufficient alignment.
      This simpler implementation means Emacs can make
      USE_STACK_LISP_OBJECTS the default unless GC_MARK_STACK !=
      GC_MAKE_GCPROS_NOOPS.
      * lisp.h (GCALIGNED): Align even if !USE_STACK_LISP_OBJECTS,
      for fewer differences among implementations.
      (struct Lisp_String): Now GCALIGNED.
      (USE_STACK_LISP_OBJECTS): Default to true, since the
      implementation no longer insists on a nonempty GCALIGNED.
      But make it false if GC_MARK_STACK != GC_MAKE_GCPROS_NOOPS.
      (SCOPED_CONS_INITIALIZER): Remove, since it's no longer needed
      separately.  Move definiens to scoped_cons.  The old definition
      was incorrect when GCALIGNED was defined to be empty.
      (union Aligned_String): New type.
      (USE_STACK_CONS, USE_STACK_STRING): New constants, so that the
      implementation ports to compilers that don't align strictly enough.
      Don't worry about the union sizes; it's not worth bothering about.
      (scoped_cons, scoped_list1, scoped_list3, scoped_list4):
      Rewrite using USE_STACK_CONS.
      (scoped_cons): Assume the use of union Aligned_Cons.
      (lisp_string_size, make_local_string, build_local_string): Remove.
      Unless otherwise specified, all callers of build_local_string
      changed to use SCOPED_STRING.
      (SCOPED_STRING): New macro.
      * data.c (wrong_choice):
      * menu.c (single_menu_item):
      * process.c (Fformat_network_address):
      Hoist use of SCOPED_STRING out of a scope, so that its returned
      object lives long enough.
      * fileio.c (Fexpand_file_name): Use build_string, not SCOPED_STRING,
      as the string might be long or might not be ASCII.

      Port to stricter C99 platforms. · 91f2d272
      Paul Eggert authored
      Especially, C99 prohibits nesting a struct X inside struct Y if
      struct X has a flexible array member.
      Also, merge from gnulib, incorporating:
      2013-11-03 intprops: port to Oracle Studio c99
      * lib/intprops.h: Update from gnulib.
      * src/alloc.c (struct sdata): New type.
      (sdata): Implement in terms of struct sdata.
      Remove u member; all uses replaced by next_vector, set_next_vector.
      (SDATA_SELECTOR, SDATA_DATA, SDATA_DATA_OFFSET): Adjust to sdata change.
      (SDATA_DATA_OFFSET): Now a constant, not a macro.
      (struct sblock): Rename first_data member to data, which is now
      a flexible array member.  All uses changed.
      (next_vector, set_next_vector, large_vector_vec): New functions.
      (vector_alignment): New constant.
      (roundup_size): Make it a multiple of ALIGNOF_STRUCT_LISP_VECTOR, too.
      (struct large-vector): Now merely a NEXT member, since the old approach
      ran afoul of stricter C99.  All uses changed to use
      large_vector_vec or large_vector_offset.
      (large_vector_offset): New constant.
      * src/dispnew.c: Include tparam.h, for tgetent.
      Do not include term.h; no longer needed.
      * src/gnutls.c (Fgnutls_boot): Don't continue after calling a _Noreturn.
      * src/lisp.h (ENUM_BF) [__SUNPRO_C && __STDC__]: Use unsigned int.
      (struct Lisp_Vector): Use a flexible array member for contents,
      instead of a union with a member that is an array of size 1.
      All uses changed.
      (ALIGNOF_STRUCT_LISP_VECTOR): New constant, to make up for the
      fact that the struct no longer contains a union.
      (struct Lisp_Misc_Any, struct Lisp_Marker, struct Lisp_Overlay)
      (struct Lisp_Save_Value, struct Lisp_Free):
      Use unsigned, not int, for spacers, to avoid c99 warning.
      (union specbinding): Use unsigned, not bool, for bitfield, as
      bool is not portable to pre-C99 hosts.

      Use C99-style flexible array members if available. · fbe9e0b9
      Paul Eggert authored
      This avoids some subtle aliasing issues, which typically
      aren't a problem with GCC but may be a problem elsewhere.
      * lib-src/ebrowse.c (struct member, struct alias, struct sym):
      Use FLEXIBLE_ARRAY_MEMBER.
      (add_sym, add_member, make_namespace, register_namespace_alias):

      that ports better to pre-C99 non-GCC.
      * src/alloc.c (sdata): New typedef, replacing the old struct sdata.
      It is a struct if GC_CHECK_STRING_BYTES, a union otherwise.
      In either case, it uses a flexible array member rather than
      the old struct hack.  All uses changed.
      (SDATA_NBYTES, sweep_strings) [!GC_CHECK_STRING_BYTES]:
      Adjust to sdata reorganization.
      * src/alloc.c (VBLOCK_BYTES_MIN, allocate_vectorlike, Fgarbage_collect):

      that ports better to pre-C99 non-GCC.
      * src/chartab.c (Fmake_char_table, make_sub_char_table, copy_char_table):
      Use CHAR_TABLE_STANDARD_SLOTS rather than its definition,
      as the latter has changed.

      Move decl to top level so it gets checked against implementation.
      (CHAR_TABLE_STANDARD_SLOTS): Adjust to struct Lisp_Char_Table change.

      Use functions, not macros, for XINT etc. · 84575e67
      Paul Eggert authored
      In lisp.h, prefer functions to function-like macros, and
      constants to object-like macros, when either will do.  This:
       . simplifies use, as there's no more need to worry about
         arguments' side effects being evaluated multiple times.
       . makes the code easier to debug on some platforms.
      However, when using gcc -O0, keep using function-like macros
      for a few critical operations, for performance reasons.
      This sort of thing isn't needed with gcc -Og, but -Og
      is a GCC 4.8 feature and isn't widely-enough available yet.
      Also, move functions from lisp.h to individual modules when possible.

      Port better to POSIX hosts lacking _setjmp. · 0328b6de
      Paul Eggert authored
      * 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.

      * character.c (str_to_unibyte): Omit last boolean argument; it was
      always 0.  All callers changed.
      * character.h, charset.h: Adjust to match previous changes.
      * character.h (char_printable_p): Remove decl of nonexistent function.
      * charset.h (struct charset): Members code_linear_p, iso_chars_96,
      ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
      are all boolean, so make them single-bit bitfields.

      port new setting code to Sun C 5.8 2005/10/13 · e757f1c6
      Paul Eggert authored
      * chartab.c, lisp.h (char_table_set, char_table_set_range):
      Return void, not Lisp_Object.  Otherwise, the compiler
      complains about (A?B:C) where B is void and C is Lisp_Object
      when compiling CHAR_TABLE_SET, due to the recent change to
      the API of sub_char_table_set_contents.
