++ 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 nonzero 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.
