      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
      * 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
      (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

      Change vectorlike from struct to union · 5d68dc9a
      Paul Eggert authored
      * src/lisp.h (vectorlike_headed): Change from struct to union.
      All uses changed.  Since it has only one member, this does not
      change semantics.  This is designed to simplify future changes
      needed to fix bugs like Bug#29040.  All uses changed.

      Fix off-by-1 bug in --enable-checking=stringbytes · 05aa6d4a
      Paul Eggert authored
      Evidently nobody builds Emacs with --enable-checking=all,
      which is no surprise as it is so slow as to be unusable nowadays.
      Perhaps we should remove the slowest checks, or move them into
      another category, or speed them up, or something.

      In particular, don't indent contained brace lists in "staircase" fashion.

      testing for being enclosed in parens, recognise also a brace directly
      following a comma, as well as a brace being the first thing inside the paren.

      whether we will accept a bracelist directly inside an open parenthesis.

      variable STATE-CACHE.  Use this variable in place of C-STATE-CACHE throughout

      At CASE 9, call that function with extra argument t.

      Use GCALIGNED properly for GCC · 9e59de94
      Paul Eggert authored
      Apparently GCC requires that ‘__attribute__ ((aligned (8)))’ must
      immediately follow the ‘struct’ keyword when aligning a structure.
      The attribute silently does not work if it follows a tag after the
      ‘struct’ keyword.  Who knew?  Anyway, this patch is designed to
      fix a SIGSEGV problem reported by John Mastro (Bug#29183).
