+// float asinhf(float)
+//
+// Overview of operation
+// ==============================================================
+//
+// There are 7 paths:
+// 1. x = 0.0
+//    Return asinhf(x) = 0.0
+// 2. 0.0 <|x| < 2^(-5)
+//    Return asinhf(x) = Pol5(x), where Pol5(x) = ((x^2)*C1 + C0)*x^3 + x
+
+// 3. 2^(-5) <= |x| < 2^51
+//    Return asinhf(x) = sign(x)*(log(|x| + sqrt(x^2 + 1.0)))
+//    To compute x + sqrt(x^2 + 1.0) modified Newton Raphson method is used
+//    (2 iterations)
+//    Algorithm description for log function see below.
+//
+// 4. 2^51 <= |x| < +INF
+//    Return asinhf(x) = sign(x)*log(2*|x|)
+//    Algorithm description for log function see below.
+//
+// 5. x = INF
+//    Return asinhf(x) = INF
+//
+// 6. x = [S,Q]NaN
+//    Return asinhf(x) = QNaN
+//
+// 7. x = denormal
+//    Return asinhf(x) = x
+//
+//==============================================================
+// 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)
+//                = -log(2^-N) - log(frcpa(1.f1 f2 ... f63))
+//
+// -log(frcpa(x)) = -log(C)
+//                = +Nlog2 - log(frcpa(1.f1 f2 ... f63))
+//
+// -log(frcpa(x)) = -log(C)
+//                = +Nlog2 + log(frcpa(1.f1 f2 ... f63))
+//
+// Log(x) = log(1/frcpa(x)) + log(frcpa(x) x)
+//
+// Log(x) =  +Nlog2 + log(1./frcpa(1.f1 f2 ... f63)) + log(frcpa(x) x)
+// Log(x) =  +Nlog2 - log(/frcpa(1.f1 f2 ... f63))   + log(frcpa(x) x)
+// Log(x) =  +Nlog2 + T                              + log(frcpa(x) x)
+//
+// Log(x) =  +Nlog2 + T                     + log(C x)
+//
+// Cx = 1 + r
+//
+// Log(x) =  +Nlog2 + T  + log(1+r)
+// Log(x) =  +Nlog2 + T  + Series( r - r^2/2 + r^3/3 - r^4/4 ....)
+//
+// 1.f1 f2 ... f8 has 256 entries.
+// They are 1 + k/2^8, k = 0 ... 255
+// These 256 values are the table entries.
+//
+// Implementation
+//==============================================================
+// C = frcpa(x)
+// r = C * x - 1
+//
+// Form rseries = r + P1*r^2 + P2*r^3 + P3*r^4
+//
+// 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 * 8
+// 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
+//
+//
+// Registers used
+//==============================================================
+// Floating Point registers used:
+// f8, input
+// f9 -> f15,  f32 -> f55
+
+// General registers used:
+// r14 -> r27
+
+// Predicate registers used:
+// p6 -> p14
+
+// p6 to filter out case when x = [Q,S]NaN or INF or zero
+// p7 to filter out case when x < 0.0
+// p8 to select path #2
+
+// p11 to filter out case when x >= 0
+// p12 to filter out case when x = + denormal
+// p13 to select path #4
+// p14 to filtef out case when x = - denormal
