| 50 | * |
| 51 | * 1) umul_ppmm(high_prod, low_prod, multipler, multiplicand) multiplies two |
| 52 | * UWtype integers MULTIPLER and MULTIPLICAND, and generates a two UWtype |
| 53 | * word product in HIGH_PROD and LOW_PROD. |
| 54 | * |
| 55 | * 2) __umulsidi3(a,b) multiplies two UWtype integers A and B, and returns a |
| 56 | * UDWtype product. This is just a variant of umul_ppmm. |
| 57 | |
| 58 | * 3) udiv_qrnnd(quotient, remainder, high_numerator, low_numerator, |
| 59 | * denominator) divides a UDWtype, composed by the UWtype integers |
| 60 | * HIGH_NUMERATOR and LOW_NUMERATOR, by DENOMINATOR and places the quotient |
| 61 | * in QUOTIENT and the remainder in REMAINDER. HIGH_NUMERATOR must be less |
| 62 | * than DENOMINATOR for correct operation. If, in addition, the most |
| 63 | * significant bit of DENOMINATOR must be 1, then the pre-processor symbol |
| 64 | * UDIV_NEEDS_NORMALIZATION is defined to 1. |
| 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 non-zero 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. |
| 89 | * |
