50: 1) umul_ppmm(high_prod, low_prod, multiplier, multiplicand) multiplies two
51: UWtype integers MULTIPLIER and MULTIPLICAND, and generates a two UWtype
52: word product in HIGH_PROD and LOW_PROD.
53:
54: 2) __umulsidi3(a,b) multiplies two UWtype integers A and B, and returns a
55: UDWtype product. This is just a variant of umul_ppmm.
56:
57: 3) udiv_qrnnd(quotient, remainder, high_numerator, low_numerator,
58: denominator) divides a UDWtype, composed by the UWtype integers
59: HIGH_NUMERATOR and LOW_NUMERATOR, by DENOMINATOR and places the quotient
60: in QUOTIENT and the remainder in REMAINDER. HIGH_NUMERATOR must be less
61: than DENOMINATOR for correct operation. If, in addition, the most
62: significant bit of DENOMINATOR must be 1, then the pre-processor symbol
63: UDIV_NEEDS_NORMALIZATION is defined to 1.
64:
65: 4) sdiv_qrnnd(quotient, remainder, high_numerator, low_numerator,
66: denominator). Like udiv_qrnnd but the numbers are signed. The quotient
67: is rounded towards 0.
68:
69: 5) count_leading_zeros(count, x) counts the number of zero-bits from the
70: msb to the first nonzero bit in the UWtype X. This is the number of
71: steps X needs to be shifted left to set the msb. Undefined for X == 0,
72: unless the symbol COUNT_LEADING_ZEROS_0 is defined to some value.
73:
74: 6) count_trailing_zeros(count, x) like count_leading_zeros, but counts
75: from the least significant end.
76:
77: 7) add_ssaaaa(high_sum, low_sum, high_addend_1, low_addend_1,
78: high_addend_2, low_addend_2) adds two UWtype integers, composed by
79: HIGH_ADDEND_1 and LOW_ADDEND_1, and HIGH_ADDEND_2 and LOW_ADDEND_2
80: respectively. The result is placed in HIGH_SUM and LOW_SUM. Overflow
81: (i.e. carry out) is not stored anywhere, and is lost.
82:
83: 8) sub_ddmmss(high_difference, low_difference, high_minuend, low_minuend,
84: high_subtrahend, low_subtrahend) subtracts two two-word UWtype integers,
85: composed by HIGH_MINUEND_1 and LOW_MINUEND_1, and HIGH_SUBTRAHEND_2 and
86: LOW_SUBTRAHEND_2 respectively. The result is placed in HIGH_DIFFERENCE
87: and LOW_DIFFERENCE. Overflow (i.e. carry out) is not stored anywhere,
88: and is lost.
