      Always allow at least double-precision bignums · 7f4558e3
      Paul Eggert authored
      Without this fix, Emacs can get into a tight loop reporting
      a range error when calculating timestamps.

      of at least twice the width of (u)intmax_t.

      Backport: fix broken build on m68k · cf545776
      Paul Eggert authored
      The GCC + valgrind fix caused the m68k build to fail (Bug#35711).
      Simplify string allocation a bit to make similar problems less
      likely in the future.
      * src/alloc.c (sdata, SDATA_NBYTES, SDATA_DATA) [GC_CHECK_STRING_BYTES]:
      Use the same implementation as with !GC_CHECK_STRING_BYTES,
      as the special case is no longer needed.
      (SDATA_ALIGN): New constant.
      (SDATA_SIZE): Remove this macro, replacing with ...
      (sdata_size): ... this new function.  All uses changed.
      Properly account for sizes and alignments even in the m68k case,
      and even if GC_CHECK_STRING_BYTES is not defined.

      Use ‘const’ to clarify GC marking · 53914a10
      Paul Eggert authored
      Add ‘const’ to make the GC marking code a bit clearer.
      This can also help the compiler in some cases, I think because
      GCC can now determine more often that the value of a static C
      variable can be cached when its address is now converted to
      ‘Lisp Object const *’ before escaping.

      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.

      List lengths are always fixnums now · 470082de
      Paul Eggert authored
      Without this patch, it was theoretically possible for a list
      length to be a bignum, which means that safe-length could
      signal an error (due to generating a too-large bignum) contrary
      to its documentation.  Fix things to remove the theoretical
      possibility, so that list lengths are always fixnums (and so
      that list lenghts are always ptrdiff_t values too, since that
      is assumed internally anyway).
      * src/alloc.c (Fcons): Do not allocate so many conses that
      a list length won’t fit into ptrdiff_t or into fixnum.
      This matters only on weird platforms; on typical platforms,
      list lengths always fit anyway.
      * src/fns.c (list_length, Fsafe_length, proper-list-p):
      Remove integer overflow checks that are no longer needed.
