28 | |
29 | 1) umul_ppmm(high_prod, low_prod, multipler, multiplicand) | |
e6c5404d TG |
30 | multiplies two USItype integers MULTIPLER and MULTIPLICAND, |
31 | and generates a two-part USItype product in HIGH_PROD and | |
e1a79915 RS |
32 | LOW_PROD. |
33 | ||
e6c5404d TG |
34 | 2) __umulsidi3(a,b) multiplies two USItype integers A and B, |
35 | and returns a UDItype product. This is just a variant of umul_ppmm. | |
e1a79915 RS |
36 | |
37 | 3) udiv_qrnnd(quotient, remainder, high_numerator, low_numerator, | |
38 | denominator) divides a two-word unsigned integer, composed by the | |
39 | integers HIGH_NUMERATOR and LOW_NUMERATOR, by DENOMINATOR and | |
40 | places the quotient in QUOTIENT and the remainder in REMAINDER. | |
41 | HIGH_NUMERATOR must be less than DENOMINATOR for correct operation. | |
42 | If, in addition, the most significant bit of DENOMINATOR must be 1, | |
43 | then the pre-processor symbol UDIV_NEEDS_NORMALIZATION is defined to 1. | |
44 | ||
b6d2adc7 TG |
45 | 4) sdiv_qrnnd(quotient, remainder, high_numerator, low_numerator, |
46 | denominator). Like udiv_qrnnd but the numbers are signed. The | |
47 | quotient is rounded towards 0. | |
48 | ||
49 | 5) count_leading_zeros(count, x) counts the number of zero-bits from | |
e1a79915 RS |
50 | the msb to the first non-zero bit. This is the number of steps X |
51 | needs to be shifted left to set the msb. Undefined for X == 0. | |
52 | ||
b6d2adc7 | 53 | 6) add_ssaaaa(high_sum, low_sum, high_addend_1, low_addend_1, |
e1a79915 RS |
54 | high_addend_2, low_addend_2) adds two two-word unsigned integers, |
55 | composed by HIGH_ADDEND_1 and LOW_ADDEND_1, and HIGH_ADDEND_2 and | |
56 | LOW_ADDEND_2 respectively. The result is placed in HIGH_SUM and | |
57 | LOW_SUM. Overflow (i.e. carry out) is not stored anywhere, and is | |
58 | lost. | |
59 | ||
b6d2adc7 | 60 | 7) sub_ddmmss(high_difference, low_difference, high_minuend, |
e1a79915 RS |
61 | low_minuend, high_subtrahend, low_subtrahend) subtracts two |
62 | two-word unsigned integers, composed by HIGH_MINUEND_1 and | |
63 | LOW_MINUEND_1, and HIGH_SUBTRAHEND_2 and LOW_SUBTRAHEND_2 | |
64 | respectively. The result is placed in HIGH_DIFFERENCE and | |
65 | LOW_DIFFERENCE. Overflow (i.e. carry out) is not stored anywhere, | |
66 | and is lost. | |
67 | ||
68 | If any of these macros are left undefined for a particular CPU, | |
69 | C macros are used. */ | |
