+/* Originally written by Paul Rubin <phr@ocf.berkeley.edu>.
    Adapted for GNU, fixed to factor UINT_MAX by Jim Meyering.
    Arbitrary-precision code adapted by James Youngman from Torbjörn

+   In 2012, the core was rewritten by Torbjörn Granlund and Niels Möller.
+   Contains code from GNU MP.  */
+
+/* Efficiently factor numbers that fit in one or two words (word = uintmax_t),
+   or, with GMP, numbers of any size.
+
+  Code organisation:
+
+    There are several variants of many functions, for handling one word, two
+    words, and GMP's mpz_t type.  If the one-word variant is called foo, the
+    two-word variant will be foo2, and the one for mpz_t will be mp_foo.  In
+    some cases, the plain function variants will handle both one-word and
+    two-word numbers, evidenced by function arguments.
+
+    The factoring code for two words will fall into the code for one word when
+    progress allows that.
+
+    Using GMP is optional.  Define HAVE_GMP to make this code include GMP
+    factoring code.  The GMP factoring code is based on GMP's demos/factorize.c
+    (last synched 2012-09-07).  The GMP-based factoring code will stay in GMP
+    factoring code even if numbers get small enough for using the two-word
+    code.
+
+  Algorithm:
+
+    (1) Perform trial division using a small primes table, but without hardware
+        division since the primes table store inverses modulo the word base.
+        (The GMP variant of this code doesn't make use of the precomputed
+        inverses, but instead relies on GMP for fast divisibility testing.)
+    (2) Check the nature of any non-factored part using Miller-Rabin for
+        detecting composites, and Lucas for detecting primes.
+    (3) Factor any remaining composite part using the Pollard-Brent rho
+        algorithm or the SQUFOF algorithm, checking status of found factors
+        again using Miller-Rabin and Lucas.
+
+    We prefer using Hensel norm in the divisions, not the more familiar
+    Euclidian norm, since the former leads to much faster code.  In the
+    Pollard-Brent rho code and the prime testing code, we use Montgomery's
+    trick of multiplying all n-residues by the word base, allowing cheap Hensel
+    reductions mod n.
+
+  Improvements:
+
+    * Use modular inverses also for exact division in the Lucas code, and
+      elsewhere.  A problem is to locate the inverses not from an index, but
+      from a prime.  We might instead compute the inverse on-the-fly.
+
+    * Tune trial division table size (not forgetting that this is a standalone
+      program where the table will be read from disk for each invocation).
+
+    * Implement less naive powm, using k-ary exponentiation for k = 3 or
+      perhaps k = 4.
+
+    * Try to speed trial division code for single uintmax_t numbers, i.e., the
+      code using DIVBLOCK.  It currently runs at 2 cycles per prime (Intel SBR,
+      IBR), 3 cycles per prime (AMD Stars) and 5 cycles per prime (AMD BD) when
+      using gcc 4.6 and 4.7.  Some software pipelining should help; 1, 2, and 4
+      respectively cycles ought to be possible.
+
+    * The redcify function could be vastly improved by using (plain Euclidian)
+      pre-inversion (such as GMP's invert_limb) and udiv_qrnnd_preinv (from
+      GMP's gmp-impl.h).  The redcify2 function could be vastly improved using
+      similar methoods.  These functions currently dominate run time when using
+      the -w option.

+
+   Let p be an odd prime, and B = 2^{W_TYPE_SIZE}. For simplicity,
+   consider the case t < B (this is the second loop below).
+
+   From our tables we get
+
+     binv = p^{-1} (mod B)
+     lim = floor ( (B-1) / p ).
+
+   First assume that t is a multiple of p, t = q * p. Then 0 <= q <= lim
+   (and all quotients in this range occur for some t).
+
+   Then t = q * p is true also (mod B), and p is invertible we get
+
+     q = t * binv (mod B).
+
+   Next, assume that t is *not* divisible by p. Since multiplication
+   by binv (mod B) is a one-to-one mapping,
+
+     t * binv (mod B) > lim,
+
+   because all the smaller values are already taken.
+
+   This can be summed up by saying that the function
+
+     q(t) = binv * t (mod B)
+
+   is a permutation of the range 0 <= t < B, with the curious property
+   that it maps the multiples of p onto the range 0 <= q <= lim, in
+   order, and the non-multiples of p onto the range lim < q < B.

+/* Define auxiliary asm macros.
+
+   1) umul_ppmm(high_prod, low_prod, multiplier, multiplicand) multiplies two
+   UWtype integers MULTIPLIER and MULTIPLICAND, and generates a two UWtype
+   word product in HIGH_PROD and LOW_PROD.
+
+   2) __umulsidi3(a,b) multiplies two UWtype integers A and B, and returns a
+   UDWtype product.  This is just a variant of umul_ppmm.
+
+   3) udiv_qrnnd(quotient, remainder, high_numerator, low_numerator,
+   denominator) divides a UDWtype, composed by the UWtype integers
+   HIGH_NUMERATOR and LOW_NUMERATOR, by DENOMINATOR and places the quotient
+   in QUOTIENT and the remainder in REMAINDER.  HIGH_NUMERATOR must be less
+   than DENOMINATOR for correct operation.  If, in addition, the most
+   significant bit of DENOMINATOR must be 1, then the pre-processor symbol
+   UDIV_NEEDS_NORMALIZATION is defined to 1.
+
+   4) sdiv_qrnnd(quotient, remainder, high_numerator, low_numerator,
+   denominator).  Like udiv_qrnnd but the numbers are signed.  The quotient
+   is rounded towards 0.
+
+   5) count_leading_zeros(count, x) counts the number of zero-bits from the
+   msb to the first non-zero bit in the UWtype X.  This is the number of
+   steps X needs to be shifted left to set the msb.  Undefined for X == 0,
+   unless the symbol COUNT_LEADING_ZEROS_0 is defined to some value.
+
+   6) count_trailing_zeros(count, x) like count_leading_zeros, but counts
+   from the least significant end.
+
+   7) add_ssaaaa(high_sum, low_sum, high_addend_1, low_addend_1,
+   high_addend_2, low_addend_2) adds two UWtype integers, composed by
+   HIGH_ADDEND_1 and LOW_ADDEND_1, and HIGH_ADDEND_2 and LOW_ADDEND_2
+   respectively.  The result is placed in HIGH_SUM and LOW_SUM.  Overflow
+   (i.e. carry out) is not stored anywhere, and is lost.
+
+   8) sub_ddmmss(high_difference, low_difference, high_minuend, low_minuend,
+   high_subtrahend, low_subtrahend) subtracts two two-word UWtype integers,
+   composed by HIGH_MINUEND_1 and LOW_MINUEND_1, and HIGH_SUBTRAHEND_2 and
+   LOW_SUBTRAHEND_2 respectively.  The result is placed in HIGH_DIFFERENCE
+   and LOW_DIFFERENCE.  Overflow (i.e. carry out) is not stored anywhere,
+   and is lost.
+
+   If any of these macros are left undefined for a particular CPU,
+   C macros are used.
+
+
+   Notes:
+
+   For add_ssaaaa the two high and two low addends can both commute, but
+   unfortunately gcc only supports one "%" commutative in each asm block.
+   This has always been so but is only documented in recent versions
+   (eg. pre-release 3.3).  Having two or more "%"s can cause an internal
+   compiler error in certain rare circumstances.
+
+   Apparently it was only the last "%" that was ever actually respected, so
+   the code has been updated to leave just that.  Clearly there's a free
+   choice whether high or low should get it, if there's a reason to favour
+   one over the other.  Also obviously when the constraints on the two
+   operands are identical there's no benefit to the reloader in any "%" at
+   all.
+
+   */
+
+/* The CPUs come in alphabetical order below.
+
+   Please add support for more CPUs here, or improve the current support
+   for the CPUs below!  */

+/* count_leading_zeros_gcc_clz is count_leading_zeros implemented with gcc
+   3.4 __builtin_clzl or __builtin_clzll, according to our limb size.
+   Similarly count_trailing_zeros_gcc_ctz using __builtin_ctzl or
+   __builtin_ctzll.
+
+   These builtins are only used when we check what code comes out, on some
+   chips they're merely libgcc calls, where we will instead want an inline
+   in that case (either asm or generic C).
+
+   These builtins are better than an asm block of the same insn, since an
+   asm block doesn't give gcc any information about scheduling or resource
+   usage.  We keep an asm block for use on prior versions of gcc though.
+
+   For reference, __builtin_ffs existed in gcc prior to __builtin_clz, but
+   it's not used (for count_leading_zeros) because it generally gives extra
+   code to ensure the result is 0 when the input is 0, which we don't need

-
-   Does not change the current directory.
-   Sets 'HOME' and 'SHELL' from the password entry for USER, and if

-   The subshell is not a login shell.

-   If one or more ARGs are given, they are passed as additional

-   I don't see the point in doing that, and it's ugly.

-
-   -DSYSLOG_NON_ROOT	Log all su's, not just those to root (UID 0).
