      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 union for the payload of struct Lisp_Vector. · d6d9cbc1
      Dmitry Antipov authored
      This helps to avoid a few glitches dictated by C's aliasing rules.
      * lisp.h (struct Lisp_Vector): Use union for next and
      contents member.  Adjust comment.  Change related users.
      * alloc.c (next_in_free_list, set_next_in_free_list): Remove.
      Related users changed.
      * buffer.c, bytecode.c, ccl.c, character.h, chartab.c, composite.c:
      * composite.h, disptab.h, fns.c, fontset.c, indent.c, keyboard.c:

      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):
      Use offsetof (struct, flex_array_member), not sizeof (struct), as
      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):
      Use offsetof (struct, flex_array_member), not sizeof (struct), as
      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.
      * src/conf_post.h (FLEXIBLE_ARRAY_MEMBER): Move here from w32.c,
      and port better to pre-C99 GCC.
      * src/image.c (struct xpm_cached_color):
      * src/lisp.h (struct Lisp_Vector, struct Lisp_Bool_Vector)
      (struct Lisp_Char_Table, struct Lisp_Sub_Char_Table):
      Use FLEXIBLE_ARRAY_MEMBER.
      * src/lisp.h (string_bytes) [GC_CHECK_STRING_BYTES]:
      Move decl to top level so it gets checked against implementation.
      (CHAR_TABLE_STANDARD_SLOTS): Adjust to struct Lisp_Char_Table change.
      * src/w32.c (FLEXIBLE_ARRAY_MEMBER): Move to conf_post.h.

      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.
      From a suggestion by Andreas Schwab in <http://bugs.gnu.org/11935#68>.

      * buffer.c (Qoverlap):
      * data.c (Qsubrp):

      If compiling via GCC without optimization, define these as macros
      in addition to inline functions.
      To disable this, compile with -DINLINING=0.
      (LISP_MACRO_DEFUN, LISP_MACRO_DEFUN_VOID): New macros.
      (check_cons_list) [!GC_CHECK_CONS_LIST]: Likewise.
      (make_number, XFASTINT, XINT, XTYPE, XUNTAG): Likewise, but
      hand-optimize only in the USE_LSB_TAG case, as GNUish hosts do that.
      (INTMASK, VALMASK): Now macros, since static values cannot be
      accessed from extern inline functions.
      (VALMASK): Also a constant, for benefit of old GDB.
      (LISP_INT_TAG_P): Remove; no longer needed as the only caller
      is INTEGERP, which can fold it in.

      USE_LSB_TAG parts; this is simpler.
      (aref_addr, gc_aset, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM)
      (max, min, struct Lisp_String, UNSIGNED_CMP, ASCII_CHAR_P):
      Move up, to avoid use before definition.
      Also include "globals.h" earlier, for the same reason.
      (make_natnum): New function.
      (XUNTAG): Now returns void *, not intptr_t, as this means fewer casts.

      Now empty functions, not macros.

      so window.h can use it.

      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.

      	The next log entry shows the actual changes by Paul Eggert.
      
       Fix a problem with aliasing and vector headers.
       GCC 4.6.0 optimizes based on type-based alias analysis.  For
       example, if b is of type struct buffer * and v of type struct
       Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
       != &v->size, and therefore "v->size = 1; b->size = 2; return
       v->size;" must therefore return 1.  This assumption is incorrect
       for Emacs, since it type-puns struct Lisp_Vector * with many other
       types.  To fix this problem, this patch adds a new type struct
       vector_header that documents the constraints on layout of vectors
       and pseudovectors, and helps optimizing compilers not get fooled
       by Emacs's type punning.  It also adds the macros XSETTYPED_PVECTYPE
       XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
       src/lisp.h (XVECTOR_SIZE): New convenience macro.  All previous uses of
       XVECTOR (foo)->size replaced to use this macro, to avoid the hassle
       of writing XVECTOR (foo)->header.size.
       src/lisp.h: Say "vectorlike header" rather than "vector header.
       (struct vectorlike_header): Rename from struct vector_header.
       (XVECTORLIKE_HEADER_SIZE): Renamed from XVECTOR_HEADER_SIZE.
       All uses changed.
       (XVECTOR_HEADER_SIZE): New macro, for use in XSETPSEUDOVECTOR.
       (XSETTYPED_PVECTYPE): New macro, specifying the name of the size
       member.
       (XSETPVECTYPE): Rewrite in terms of new macro.
       (XSETPVECTYPESIZE): New macro, specifying both type and size.
       This is a bit clearer, and further avoids the possibility of
       undesirable aliasing.
       (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
       (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR
       and XVECTOR_HEADER_SIZE.
       (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
       since Lisp_Subr is a special case (no "next" field).
       (ASIZE): Rewrite in terms of XVECTOR_SIZE.
       (struct vector_header): New type.
       (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
       object, to help avoid aliasing.
       (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
       (SUBRP): Likewise, since Lisp_Subr is a special case.
       src/lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
       (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
       (struct Lisp_Hash_Table): Combine first two members into a single
       struct vector_header member.  All uses of "size" and "next" members
       changed to be "header.size" and "header.next".
       src/buffer.h (struct buffer): Likewise.
       src/font.h (struct font_spec, struct font_entity, struct font): Likewise.
       src/frame.h (struct frame): Likewise.
       src/process.h (struct Lisp_Process): Likewise.
       src/termhooks.h (struct terminal): Likewise.
       src/window.c (struct save_window_data, struct saved_window): Likewise.
       src/window.h (struct window): Likewise.
       src/alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
       Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
       src/buffer.c (init_buffer_once): Likewise.
       src/lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
       special case.
       src/process.c (Fformat_network_address): Use local var for size,
       for brevity.
       src/fns.c (vector): Remove; this old hack is no longer needed.
       src/bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.

      Make Emacs functions such as Fatom 'static' by default. · 16a97296
      Paul Eggert authored
      This makes it easier for human readers (and static analyzers)
      to see whether these functions can be called from other modules.
      DEFUN now defines a static function.  To make the function external
      so that it can be used in other C modules, use the new macro DEFUE.
      * lisp.h (DEFINE_FUNC): New macro, with the old contents of DEFUN.
      (DEFUN): Rewrite in terms of DEFINE_FUNC.  It now generates a
      static function definition.  Use DEFUE if you want an extern one.
      (DEFUE, INFUN): New macros.
      (Funibyte_char_to_multibyte, Fsyntax_table_p, Finit_image_library):
      (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
      (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
      (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
      Remove decls, since these functions are now static.
      (Funintern, Fget_internal_run_time): New decls, since these functions
      were already external.
      * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
      * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:
      * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, floatfns.c:
      * fns.c, font.c, fontset.c, frame.c, image.c, indent.c:
      * keyboard.c, keymap.c, lread.c:
      * macros.c, marker.c, menu.c, minibuf.c, print.c, process.c, search.c:
      * syntax.c, term.c, terminal.c, textprop.c, undo.c:
      * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
      Mark functions with DEFUE instead of DEFUN,
      if they are used in other modules.
      * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
      decls for now-static functions.
      * buffer.h (Fdelete_overlay): Remove decl.
      * callproc.c (Fgetenv_internal): Mark as internal.
      * composite.c (Fremove_list_of_text_properties): Remove decl.
      (Fcomposition_get_gstring): New forward static decl.
      * composite.h (Fcomposite_get_gstring): Remove decl.
      * dired.c (Ffile_attributes): New forward static decl.
      * doc.c (Fdocumntation_property): New forward static decl.
      * eval.c (Ffetch_bytecode): New forward static decl.
      (Funintern): Remove extern decl; now in .h file where it belongs.
      * fileio.c (Fmake_symbolic_link): New forward static decl.
      * image.c (Finit_image_library): New forward static decl.
      * insdel.c (Fcombine_after_change_execute): Make forward decl static.
      * intervals.h (Fprevious_property_change):
      (Fremove_list_of_text_properties): Remove decls.
      * keyboard.c (Fthis_command_keys): Remove decl.
      (Fcommand_execute): New forward static decl.
      * keymap.c (Flookup_key): New forward static decl.
      (Fcopy_keymap): Now static.
      * keymap.h (Flookup_key): Remove decl.
      * process.c (Fget_process): New forward static decl.
      (Fprocess_datagram_address): Mark as internal.
      * syntax.c (Fsyntax_table_p): New forward static decl.
      (skip_chars): Remove duplicate decl.
      * textprop.c (Fprevious_property_change): New forward static decl.
      * window.c (Fset_window_fringes, Fset_window_scroll_bars):
      Now internal.
      (Fset_window_margins, Fset_window_vscroll): New forward static decls.
      * window.h (Fset_window_vscroll, Fset_window_margins): Remove decls.
