      Stefan Monnier authored
      (profiler-format): Hide the tail with `invisible' so that C-s can still
      find the hidden elements.

      Improve support for popcount and counting trailing zeros. · 595e113b
      Paul Eggert authored
      Do this by using the Gnulib modules for this.
      This should generate faster code on non-GCC, non-MSC platforms,
      and make the code a bit more portable, at least in theory.
      * admin/merge-gnulib (GNULIB_MODULES): Add count-one-bits
      and count-trailing-zeros.
      * lib/count-one-bits.c, lib/count-one-bits.h:
      * lib/count-trailing-zeros.c, lib/count-trailing-zeros.h:
      * m4/count-one-bits.m4, m4/count-trailing-zeros.m4:
      New files, copied from gnulib.
      * lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate.
      * nt/gnulib.mk: Merge changes from lib/gnulib.mk.
      * src/data.c: Include <count-one-bits.h>, <count-trailing-zeros.h>.
      (USE_MSC_POPCOUNT, POPCOUNT_STATIC_INLINE)
      (NEED_GENERIC_POPCOUNT, popcount_size_t_generic)
      (popcount_size_t_msc, popcount_size_t_gcc):
      Remove; now done by Gnulib.
      (popcount_size_t): Now a macro that defers to Gnulib.
      (count_trailing_zero_bits): Return int, for consistency with
      Gnulib and because Emacs prefers signed to unsigned int.
      Don't assume that size_t is either unsigned int or unsigned long
      or unsigned long long.
      (size_t_to_host_endian): Do not assume that size_t is either
      exactly 32 or exactly 64 bits wide.
      * src/lisp.h (BITS_PER_SIZE_T): Define consistently with BITS_PER_LONG
      etc., so that it's now an enum constant, not a macro.
      No need to assume that it's either 32 or 64.

      * alloc.c (valid_pointer_p) [!WINDOWSNT]: Remove now-unnecessary cast.
      * sysdep.c (emacs_read, emacs_write, emacs_write_sig):
      Buffer arg is now void *, not char *.  This matches plain
      'read' and 'write' better, and avoids a constraint violation
      on Solaris 9 with Oracle Studio.

      memset to explicit loop.  Otherwise copy largest possible chunk
      from initialized to uninitialized part, thus allowing the longer
      memcpy runs and reducing the number of loop iterations.

      * lisp.h (eassert): Assume that COND is true when optimizing. · 75273afb
      Paul Eggert authored
      In other words, take on the behavior of eassert_and_assume.
      This makes Emacs 0.2% smaller on my platform (Fedora 19, x86-64).
      (eassert_and_assume): Remove.  All uses replaced by eassert.

      when the argument contains locals clobbered by longjmp.
      Don't use clobbered locals outside of clobbered_eassert.
      (internal_lisp_condition_case): Use a volatile variable
      to work around a local variable's getting clobbered.
