      Fix byte compilation of (eq foo 'default) · 9af399fd
      Paul Eggert authored
      Do not use the symbol ‘default’ as a special marker.
      Instead, use a value that cannot appear in the program,
      improving on a patch proposed by Robert Cochran (Bug#31718#14).

      This is a streamlined version of Lisp_Save_Value, which contains just
      a pointer, as that is all Lisp_Save_Values are used for any more.

      Remove some wrong 8-byte alignment assumptions · 967d2c55
      Paul Eggert authored
      Do not assume that 8-byte alignment suffices for all C objects,
      as some platforms require 16-byte alignment for some objects,
      and this will start to bite us as time goes on (e.g., if an
      Emacs module ever uses an object containing a long
      double, which requires 16-byte alignment on x86-64).
      Conversely, on !USE_LSB_TAG platforms, do not insist on
      aligning Lisp objects to a multiple of 8, as this is not
      needed for high-order tag bits.
      * src/alloc.c (LISP_ALIGNMENT, MALLOC_IS_LISP_ALIGNED):
      New constants.
      (XMALLOC_BASE_ALIGNMENT, XMALLOC_HEADER_ALIGNMENT):
      Removed.  All uses replaced by LISP_ALIGNMENT.
      (aligned_alloc, laligned, lmalloc, lrealloc, union aligned_Lisp_Misc)
      (maybe_lisp_pointer, pure_alloc):
      Use LISP_ALIGNMENT rather than GCALIGNMENT.
      (aligned_alloc): Do not worry about an alignment of
      LISP_ALIGNMENT when MALLOC_IS_LISP_ALIGNED, as the code never
      uses aligned_alloc with alignment == LISP_ALIGNMENT in that case.
      (__alignof__): Remove.  All uses removed.
      (MALLOC_IS_GC_ALIGNED): Remove.
      All uses replaced with MALLOC_IS_LISP_ALIGNED.
      (vector_alignment): Remove.
      All uses replaced with LISP_ALIGNMENT.
      * src/alloc.c (mark_maybe_pointer):
      * src/emacs-module.c (value_to_lisp_bits):
      Do not assume GCALIGNMENT == 1 << GCTYPEBITS, as GCALIGNMENT
      is 1 on !USE_LSB_TAG platforms now.
      * src/lisp.h (GCALIGNMENT) [!USE_LSB_TAG]: Now 1.

      Clarify that enabling a theme does not disable other themes · b8478b2a
      Daniel Colascione authored
      Avoid user confusion by explicitly stating that enabling a theme does
      not imply disabling other themes and that theme load functions are not
      theme switch functions.
      
      * lisp/custom.el (load-theme, enable-theme): Clarify docstrings.

      Ignore focus events for dead frames · 5ed11914
      Daniel Colascione authored
      Frames can die between the time we generate a focus event and the time
      we get around to processing it.  Do run after-focus-change-function,
      since that's idempotent and we want to make sure not to miss
      any changes.
      
      * lisp/frame.el (handle-focus-in, handle-focus-out): Check for dead frames.
