+ * va_list also holds offsets in the register save area for the next general

+ * Unlike Linux, the Windows va_list is just a pointer to the stack. No

+ * va_list so that the register save area is never used. For that goal, we set
+ * the offsets to the maximal allowed values, meaning that the arguments passed
+ * in the registers have been exhausted. The values are 48 for general purpose
+ * registers (6 registers, 8 bytes each) and 304 for floating point registers
+ * (16 registers, 16 bytes each, on top of general purpose register).

+
+ 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 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.
+
