      Remove printmax_t etc. · 8f522efe
      Paul Eggert authored
      printmax_t etc. were needed only for platforms that lacked
      support for printing intmax_t.  These platforms are now so
      obsolete that they are no longer practical porting targets.
      * src/image.c (gs_load): Fix unlikely buffer overrun
      discovered while making these changes.  It was introduced in

      Revert "Remove font.c code commented out for a decade" · 5ae407aa
      Eli Zaretskii authored
      This reverts commit 64d0cd98.
      
      Rationale: any font-related code and comments, even if unused
      for decades, serves as important source of useful information
      in an area of Emacs code that is notoriously under-documented.
      
      Please do NOT remove this stuff until we have an active
      expert in this are on board, who will then decide whether
      this can be retired.

      Simplify list creation in C code · 5c2563a5
      Paul Eggert authored
      The main new thing here is that C code can now say
      ‘list (a, b, c, d, e, f)’ instead of
      ‘listn (CONSTYPE_HEAP, 6, a, b, c, d, e, f)’,
      thus relieving callers of the responsibility of counting
      arguments (plus, the code feels more like Lisp).  The old
      list1 ... list5 functions remain, as they’re probably a bit
      faster for small lists.
      * src/alloc.c (cons_listn, pure_listn): New functions.
      (listn): Omit enum argument.
      All callers changed to use either new ‘list’ or ‘pure_list’ macros.

      Improve bignum support for system types · d77d01d2
      Paul Eggert authored
      Use bignums when Emacs converts to and from system types like
      off_t for file sizes whose values can exceed fixnum range.
      Formerly, Emacs sometimes generted floats and sometimes ad-hoc
      conses of integers.  Emacs still accepts floats and conses for
      these system types, in case some stray Lisp code is generating
      them, though this usage is obsolescent.

      Pacify gcc -Og -Wuninitialized · a1e0868f
      Paul Eggert authored
      This addresses the -Og uninitialized variable warnings I ran
      into on Fedora 28, which uses 8.1.1 20180712 (Red Hat 8.1.1-5).
      It also changes some explicit initializations to UNINIT
      when the variable does not actually need to be initialized.

      Use native alignment to access Lisp object data · 0303fab3
      Paul Eggert authored
      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.
