// ==============================================================
// History
// ==============================================================
// 04/02/01 Initial version
// 04/19/01 Improved speed of the paths #1,2,3,4,5
// 10/18/01 Improved accuracy
// 05/20/02 Cleaned up namespace and sf0 syntax
// 02/06/03 Reordered header: .section, .global, .proc, .align
// 05/21/03 Improved performance, fixed to handle unorms
// 03/31/05 Reformatted delimiters between data tables
//
// API
// ==============================================================
// double asinh(double)
//
// Overview of operation
// ==============================================================
//
// There are 7 paths:
// 1. x = 0.0
//    Return asinh(x) = 0.0
//
// 2. 0.0 <|x| < 2^(-3)
//    Return asinh(x) = POL13(x),
//         where POL13(x) = (x^2*C13 + ...)*x^2 + C5)*x^2 + C3)*x^3 + x
//
// 3. 2^(-3) <= |x| < 2^63
//    Return asinh(x) = sign(x)*(log(|x| + sqrt(x^2 + 1.0)))
//    To compute x + sqrt(x^2 + 1.0) modified Newton Raphson method is used
//      (3 iterations)
//    Algorithm description for log function see below.
//
// 4. 2^63 <= |x| < +INF
//    Return asinh(x) = sign(x)*log(2*|x|)
//    Algorithm description for log function see below.
//
// 5. x = INF
//    Return asinh(x) = INF
//
// 6. x = [S,Q]NaN
//    Return asinh(x) = QNaN
//
// 7. x = denormal
//    Return asinh(x) = x correctly rounded
//
//==============================================================
// Algorithm Description for log(x) function
// Below we are using the fact that inequality x - 1.0 > 2^(-6) is always
//   true for this asinh implementation
//
// Consider  x = 2^N 1.f1 f2 f3 f4...f63
// Log(x) = log(frcpa(x) x/frcpa(x))
//        = log(1/frcpa(x)) + log(frcpa(x) x)
//        = -log(frcpa(x)) + log(frcpa(x) x)
//
// frcpa(x)       = 2^-N frcpa((1.f1 f2 ... f63)
//
// -log(frcpa(x)) = -log(C)

//
// Implementation
//==============================================================
// C = frcpa(x)
// r = C * x - 1
//
// Form rseries = r + P1*r^2 + P2*r^3 + P3*r^4 + P4*r^5 + P5*r^6
//
// x = f * 2*n where f is 1.f_1f_2f_3....f_63
// Nfloat = float(n)  where n is the true unbiased exponent
// pre-index = f_1f_2....f_8
// index = pre_index * 16
// get the dxt table entry at index + offset = T
//
// result = (T + Nfloat * log(2)) + rseries
//
// The T table is calculated as follows
// Form x_k = 1 + k/2^8 where k goes from 0... 255
//      y_k = frcpa(x_k)
//      log(1/y_k)  in quad and round to double-extended
//

// p8 to select path #2
// p9 used in the frcpa from path #3
// p11 to filter out case when x >= 0
// p12 to filter out case when x = unorm
// p13 to select path #4
