+ * RETURN ARG (X+iY)
+ * DOUBLE PRECISION (VAX D format 56 bits, IEEE DOUBLE 53 BITS)
+ * CODED IN C BY K.C. NG, 1/8/85;

+ *
+ * Required system supported functions :
+ * copysign(x,y)
+ * scalb(x,y)
+ * logb(x)
+ *
+ * Method :
+ * 1. Reduce y to positive by atan2(y,x)=-atan2(-y,x).
+ * 2. Reduce x to positive by (if x and y are unexceptional):
+ * ARG (x+iy) = arctan(y/x) ... if x > 0,
+ * ARG (x+iy) = pi - arctan[y/(-x)] ... if x < 0,
+ * 3. According to the integer k=4t+0.25 truncated , t=y/x, the argument
+ * is further reduced to one of the following intervals and the
+ * arctangent of y/x is evaluated by the corresponding formula:
+ *
+ * [0,7/16] atan(y/x) = t - t^3*(a1+t^2*(a2+...(a10+t^2*a11)...)
+ * [7/16,11/16] atan(y/x) = atan(1/2) + atan( (y-x/2)/(x+y/2) )
+ * [11/16.19/16] atan(y/x) = atan( 1 ) + atan( (y-x)/(x+y) )
+ * [19/16,39/16] atan(y/x) = atan(3/2) + atan( (y-1.5x)/(x+1.5y) )
+ * [39/16,INF] atan(y/x) = atan(INF) + atan( -x/y )
+ *
+ * Special cases:
+ * Notations: atan2(y,x) == ARG (x+iy) == ARG(x,y).
+ *
+ * ARG( NAN , (anything) ) is NaN;
+ * ARG( (anything), NaN ) is NaN;
+ * ARG(+(anything but NaN), +-0) is +-0 ;
+ * ARG(-(anything but NaN), +-0) is +-PI ;
+ * ARG( 0, +-(anything but 0 and NaN) ) is +-PI/2;
+ * ARG( +INF,+-(anything but INF and NaN) ) is +-0 ;
+ * ARG( -INF,+-(anything but INF and NaN) ) is +-PI;
+ * ARG( +INF,+-INF ) is +-PI/4 ;
+ * ARG( -INF,+-INF ) is +-3PI/4;
+ * ARG( (anything but,0,NaN, and INF),+-INF ) is +-PI/2;
+ *
+ * Accuracy:
+ * atan2(y,x) returns (PI/pi) * the exact ARG (x+iy) nearly rounded,
+ * where
+ *
+ * in decimal:
+ * pi = 3.141592653589793 23846264338327 .....
+ * 53 bits PI = 3.141592653589793 115997963 ..... ,
+ * 56 bits PI = 3.141592653589793 227020265 ..... ,
+ *
+ * in hexadecimal:
+ * pi = 3.243F6A8885A308D313198A2E....
+ * 53 bits PI = 3.243F6A8885A30 = 2 * 1.921FB54442D18 error=.276ulps
+ * 56 bits PI = 3.243F6A8885A308 = 4 * .C90FDAA22168C2 error=.206ulps
+ *
+ * In a test run with 356,000 random argument on [-1,1] * [-1,1] on a
+ * VAX, the maximum observed error was 1.41 ulps (units of the last place)
+ * compared with (PI/pi)*(the exact ARG(x+iy)).
+ *
+ * Note:
+ * We use machine PI (the true pi rounded) in place of the actual
+ * value of pi for all the trig and inverse trig functions. In general,
+ * if trig is one of sin, cos, tan, then computed trig(y) returns the
+ * exact trig(y*pi/PI) nearly rounded; correspondingly, computed arctrig
+ * returns the exact arctrig(y)*PI/pi nearly rounded. These guarantee the
+ * trig functions have period PI, and trig(arctrig(x)) returns x for
+ * all critical values x.
+ *
+ * Constants:
+ * The hexadecimal values are the intended ones for the following constants.
+ * The decimal values may be used, provided that the compiler will convert
+ * from decimal to binary accurately enough to produce the hexadecimal values
+ * shown.

+ *
+ * Kernel function:
+ * exp__E(x,c)
+ *
+ * Method:
+ * 1. Argument Reduction: given the input x, find r and integer k such
+ * that
+ * x = k*ln2 + r, |r| <= 0.5*ln2 .
+ * r will be represented as r := z+c for better accuracy.
+ *
+ * 2. Compute EXPM1(r)=exp(r)-1 by
+ *
+ * EXPM1(r=z+c) := z + exp__E(z,c)
+ *
+ * 3. EXPM1(x) = 2^k * ( EXPM1(r) + 1-2^-k ).
+ *
+ * Remarks:
+ * 1. When k=1 and z < -0.25, we use the following formula for
+ * better accuracy:
+ * EXPM1(x) = 2 * ( (z+0.5) + exp__E(z,c) )
+ * 2. To avoid rounding error in 1-2^-k where k is large, we use
+ * EXPM1(x) = 2^k * { [z+(exp__E(z,c)-2^-k )] + 1 }
+ * when k>56.
+ *
+ * Special cases:
+ * EXPM1(INF) is INF, EXPM1(NaN) is NaN;
+ * EXPM1(-INF)= -1;
+ * for finite argument, only EXPM1(0)=0 is exact.
+ *
+ * Accuracy:
+ * EXPM1(x) returns the exact (exp(x)-1) nearly rounded. In a test run with
+ * 1,166,000 random arguments on a VAX, the maximum observed error was
+ * .872 ulps (units of the last place).
+ *
+ * Constants:
+ * The hexadecimal values are the intended ones for the following constants.
+ * The decimal values may be used, provided that the compiler will convert
+ * from decimal to binary accurately enough to produce the hexadecimal values

+ *
+ * This code was derived, with minor modifications, from:
+ * Peter Tang, "Table-Driven Implementation of the
+ * Logarithm in IEEE Floating-Point arithmetic." ACM Trans.
+ * Math Software, vol 16. no 4, pp 378-400, Dec 1990).
+ *
+ * Calculates log(2^m*F*(1+f/F)), |f/j| <= 1/256,
+ * where F = j/128 for j an integer in [0, 128].
+ *
+ * log(2^m) = log2_hi*m + log2_tail*m
+ * since m is an integer, the dominant term is exact.
+ * m has at most 10 digits (for subnormal numbers),
+ * and log2_hi has 11 trailing zero bits.
+ *
+ * log(F) = logF_hi[j] + logF_lo[j] is in tabular form in log_table.h
+ * logF_hi[] + 512 is exact.
+ *
+ * log(1+f/F) = 2*f/(2*F + f) + 1/12 * (2*f/(2*F + f))**3 + ...
+ * the leading term is calculated to extra precision in two
+ * parts, the larger of which adds exactly to the dominant
+ * m and F terms.
+ * There are two cases:
+ * 1. when m, j are non-zero (m | j), use absolute
+ * precision for the leading term.
+ * 2. when m = j = 0, |1-x| < 1/256, and log(x) ~= (x-1).
+ * In this case, use a relative precision of 24 bits.
+ * (This is done differently in the original paper)
+ *
+ * Special cases:
+ * 0 return signalling -Inf
+ * neg return signalling NaN
+ * +Inf return +Inf

+ * RETURN THE LOGARITHM OF 1+x
+ * DOUBLE PRECISION (VAX D FORMAT 56 bits, IEEE DOUBLE 53 BITS)
+ * CODED IN C BY K.C. NG, 1/19/85;
+ * REVISED BY K.C. NG on 2/6/85, 3/7/85, 3/24/85, 4/16/85.
+ *
+ * Required system supported functions:
+ * scalb(x,n)
+ * copysign(x,y)
+ * logb(x)
+ * finite(x)
+ *
+ * Required kernel function:
+ * log__L(z)
+ *
+ * Method :
+ * 1. Argument Reduction: find k and f such that
+ * 1+x = 2^k * (1+f),
+ * where sqrt(2)/2 < 1+f < sqrt(2) .
+ *
+ * 2. Let s = f/(2+f) ; based on log(1+f) = log(1+s) - log(1-s)
+ * = 2s + 2/3 s**3 + 2/5 s**5 + .....,
+ * log(1+f) is computed by
+ *
+ * log(1+f) = 2s + s*log__L(s*s)
+ * where
+ * log__L(z) = z*(L1 + z*(L2 + z*(... (L6 + z*L7)...)))
+ *
+ * See log__L() for the values of the coefficients.
+ *
+ * 3. Finally, log(1+x) = k*ln2 + log(1+f).
+ *
+ * Remarks 1. In step 3 n*ln2 will be stored in two floating point numbers
+ * n*ln2hi + n*ln2lo, where ln2hi is chosen such that the last
+ * 20 bits (for VAX D format), or the last 21 bits ( for IEEE
+ * double) is 0. This ensures n*ln2hi is exactly representable.
+ * 2. In step 1, f may not be representable. A correction term c
+ * for f is computed. It follows that the correction term for
+ * f - t (the leading term of log(1+f) in step 2) is c-c*x. We
+ * add this correction term to n*ln2lo to attenuate the error.
+ *
+ *
+ * Special cases:
+ * log1p(x) is NaN with signal if x < -1; log1p(NaN) is NaN with no signal;
+ * log1p(INF) is +INF; log1p(-1) is -INF with signal;
+ * only log1p(0)=0 is exact for finite argument.
+ *
+ * Accuracy:
+ * log1p(x) returns the exact log(1+x) nearly rounded. In a test run
+ * with 1,536,000 random arguments on a VAX, the maximum observed
+ * error was .846 ulps (units in the last place).
+ *
+ * Constants:
+ * The hexadecimal values are the intended ones for the following constants.
+ * The decimal values may be used, provided that the compiler will convert
+ * from decimal to binary accurately enough to produce the hexadecimal values
+ * shown.

+ propagating from its left will fall into the hole at its
+ least significant bit and stop. Since there will be no
+ carry from its most significant bit, the LSB of the
+ byte to the left will be unchanged, and the zero will be
+ detected.
+
+ 2) Is this worthwhile? Will it ignore everything except
+ zero bytes? Suppose every byte of LONGWORD has a bit set
+ somewhere. There will be a carry into bit 8. If bit 8
+ is set, this will carry into bit 16. If bit 8 is clear,
+ one of bits 9-15 must be set, so there will be a carry
+ into bit 16. Similarly, there will be a carry into bit
+ 24. If one of bits 24-30 is set, there will be a carry
+ into bit 31, so all of the hole bits will be changed.
+
+ The one misfire occurs when bits 24-30 are clear and bit
+ 31 is set; in this case, the hole at bit 31 is not
+ changed. If we had access to the processor carry flag,

+ properly.

+ ******************************************************************************
+ * WARNING:
+ * These codes are developed (in double) to support the C elementary
+ * functions temporarily. They are not universal, and some of them are very
+ * slow (in particular, drem and sqrt is extremely inefficient). Each
+ * computer system should have its implementation of these functions using
+ * its own assembler.
+ ******************************************************************************
+ *
+ * IEEE 754 required operations:
+ * drem(x,p)
+ * returns x REM y = x - [x/y]*y , where [x/y] is the integer
+ * nearest x/y; in half way case, choose the even one.
+ * sqrt(x)
+ * returns the square root of x correctly rounded according to
+ * the rounding mod.
+ *
+ * IEEE 754 recommended functions:
+ * (a) copysign(x,y)
+ * returns x with the sign of y.
+ * (b) scalb(x,N)
+ * returns x * (2**N), for integer values N.
+ * (c) logb(x)
+ * returns the unbiased exponent of x, a signed integer in
+ * double precision, except that logb(0) is -INF, logb(INF)
+ * is +INF, and logb(NAN) is that NAN.
+ * (d) finite(x)
+ * returns the value TRUE if -INF < x < +INF and returns
+ * FALSE otherwise.

+; Common overhead is about 11 cycles/invocation.
+
+; The speed for S2_LIMB >= 0x10000 is approximately 21 cycles/limb. (The
+; pipeline stalls 2 cycles due to WB contention.)
+
+; The speed for S2_LIMB < 0x10000 is approximately 16 cycles/limb. (The
+; pipeline stalls 2 cycles due to WB contention and 1 cycle due to latency.)
+
+; To enhance speed:
+; 1. Unroll main loop 4-8 times.
+; 2. Schedule code to avoid WB contention. It might be tempting to move the
+; ld instruction in the loops down to save 2 cycles (less WB contention),
+; but that looses because the ultimate value will be read from outside
+; the allocated space. But if we handle the ultimate multiplication in
+; the tail, we can do this.
+; 3. Make the multiplication with less instructions. I think the code for
+; (S2_LIMB >= 0x10000) is not minimal.
+; With these techniques the (S2_LIMB >= 0x10000) case would run in 17 or
