      Use alignas to fix GCALIGN-related bugs · b1573a97
      Paul Eggert authored
      Use alignas and unions to specify alignments of objects needing
      addresses that are at least a multiple of GCALIGNMENT.  Using
      these standard C facilities should be safer than relying on ad hoc
      and poorly-understood features like GCC’s __attribute__
      ((aligned (N))), the root cause for recent porting bugs like
      Bug#29040.  The alignas macro was standardized by C11 and Gnulib
      supports alignas for pre-C11 platforms.  I have tested this on Sun
      Studio 12 sparc (2007) and GCC 4.4.7 x86-64 (2012) as well as on
      more recent platforms like GCC 7.2.1 (2017) on Fedora 26 (both
      x86-64 and x86).
      * lib-src/make-docfile.c (close_emacs_globals): lispsym is now
      just an array of struct Lisp_Symbol, since struct Lisp_Symbol is
      now properly aligned.  All uses changed.
      * src/alloc.c (NEXT_FREE_LISP_STRING): Just use the new u.next
      member; this is simpler and safer than casting a pointer that
      might not be aligned properly.
      (aligned_Lisp_Symbol): Remove.  No longer needed, now that struct
      Lisp_Symbol is aligned properly.  All uses replaced with struct
      Lisp_Symbol.
      * src/lisp.h (GCALIGNED): Remove, as it does not work as expected:
      it can cause the natural alignment to be ignored.  All uses
      replaced by unions with a ‘char alignas (GCALIGNMENT)’ member as
      described below.
      (struct Lisp_Symbol, struct Lisp_Cons, struct Lisp_String):
      Change definition from ‘struct TAG { MEMBERS };’ to
      ‘struct TAG { union { struct { MEMBERS } s; char alignas
      (GCALIGNMENT) gcaligned; } u; };’.  This guarantees ‘struct TAG’
      to have an alignment that at least max (GCALIGNMENT, N) where N is
      its old alignment.  All uses like ‘PTR->MEMBER’ changed to
      ‘PTR->u.s.MEMBER’; these uses were supposed to be mostly private
      anyway.  Verify that the resulting ‘struct TAG’ is properly
      aligned for Emacs.
      (union vectorlike_header): New member ‘gcaligned’ to guarantee
      that this type, and its containing types like ‘struct Lisp_Subr’,
      ‘struct buffer’ and ‘struct thread_state’, are all properly
      aligned for Emacs.
      (struct Lisp_String): New union member ‘next’, for the benefit
      of NEXT_FREE_LISP_STRING.
      (union Aligned_Cons, union Aligned_String): Remove.  All uses
      replaced by struct Lisp_Cons and struct Lisp_String, since they
      are now properly aligned.
      (USE_STACK_CONS, USE_STACK_STRING): Simplify now that we can
      assume struct Lisp_Cons and struct Lisp_String are properly
      aligned.

      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.

      New internal-border face and args for select-window and x-focus-frame · c25005ed
      Martin Rudalics authored
      Add `internal-border' face and handle it whenever clearing the

      'mark-for-redisplay', `select-window' will not record the window
      but still mark it for redisplay.  The new argument NOACTIVATE

      (scroll-bar-toolkit-horizontal-scroll): Select window to scroll
      with `mark-for-redisplay'.

      `focus-follows-mouse' is not 'auto-raise' try to not activate
      FRAME.
      * src/dispextern.h (face_id): Add INTERNAL_BORDER_FACE_ID.

      This activates a change that was installed a few weeks ago but whose
      ChangeLog was inadvertently dropped during its commit.  The proper
      ChangeLog is included below as part of the present commit.

      PPosition, USPosition and USSize flags if requested.

      x_gtk_use_window_move is set, leave it entirely to

      Replace QUIT with maybe_quit · b3a3ed52

      There’s no longer need to have QUIT stand for a slug of C statements.
      Use the more-obvious function-call syntax instead.
      Also, use true and false when setting immediate_quit.
      These changes should not affect the generated machine code.

      the loop could sometimes before the frame turned visible, and for some
