 * UDWtype -- An unsigned type, at least twice as large a UWtype
 * W_TYPE_SIZE -- size in bits of UWtype

/* Define auxiliary asm macros.
 *
 * 1) umul_ppmm(high_prod, low_prod, multipler, multiplicand) multiplies two
 * UWtype integers MULTIPLER 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 non-zero 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.
 *
 * If any of these macros are left undefined for a particular CPU,
 * C macros are used.  */
