+   1) umul_ppmm(high_prod, low_prod, multipler, multiplicand)
+   multiplies two u32 integers MULTIPLER and MULTIPLICAND,
+   and generates a two-part u32 product in HIGH_PROD and
+   LOW_PROD.
+
+   2) __umulsidi3(a,b) multiplies two u32 integers A and B,
+   and returns a u64 product.  This is just a variant of umul_ppmm.
+
+   3) udiv_qrnnd(quotient, remainder, high_numerator, low_numerator,
+   denominator) divides a two-word unsigned integer, composed by the
+   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.  This is the number of steps X
+   needs to be shifted left to set the msb.  Undefined for X == 0.
+
+   6) add_ssaaaa(high_sum, low_sum, high_addend_1, low_addend_1,
+   high_addend_2, low_addend_2) adds two two-word unsigned 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.
+
+   7) sub_ddmmss(high_difference, low_difference, high_minuend,
+   low_minuend, high_subtrahend, low_subtrahend) subtracts two
+   two-word unsigned 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.
