+// Overview of operation
+//==============================================================
+// Background
+// ----------
+//
+// This algorithm is based on fact that
+// log(a b) = log(a) + log(b).
+// In our case we have x = 2^N f, where 1 <= f < 2.
+// So
+//   log(x) = log(2^N f) = log(2^N) + log(f) = n*log(2) + log(f)
+//
+// To calculate log(f) we do following
+//   log(f) = log(f * frcpa(f) / frcpa(f)) =
+//          = log(f * frcpa(f)) + log(1/frcpa(f))
+//
+// According to definition of IA-64's frcpa instruction it's a
+// floating point that approximates 1/f using a lookup on the
+// top of 8 bits of the input number's significand with relative
+// error < 2^(-8.886). So we have following
+//
+// |(1/f - frcpa(f)) / (1/f))| = |1 - f*frcpa(f)| < 1/256
+//
+// and
+//
+// log(f) = log(f * frcpa(f)) + log(1/frcpa(f)) =
+//        = log(1 + r) + T
+//
+// The first value can be computed by polynomial P(r) approximating
+// log(1 + r) on |r| < 1/256 and the second is precomputed tabular
+// value defined by top 8 bit of f.
+//
+// Finally we have that  log(x) ~ (N*log(2) + T) + P(r)
+//
+// Note that if input argument is close to 1.0 (in our case it means
+// that |1 - x| < 1/256) we can use just polynomial approximation
+// because x = 2^0 * f = f = 1 + r and
+// log(x) = log(1 + r) ~ P(r)
+//
+//
+// To compute log10(x) we use the simple identity
+//
+//  log10(x) = log(x)/log(10)
+//
+// so we have that
+//
+//  log10(x) = (N*log(2) + T  + log(1+r)) / log(10) =
+//           = N*(log(2)/log(10)) + (T/log(10)) + log(1 + r)/log(10)
+//
+//
+// Implementation
+// --------------
+// It can be seen that formulas for log and log10 differ from one another
+// only by coefficients and tabular values. Namely as log as log10 are
+// calculated as (N*L1 + T) + L2*Series(r) where in case of log
+//   L1 = log(2)
+//   T  = log(1/frcpa(x))
+//   L2 = 1.0
+// and in case of log10
+//   L1 = log(2)/log(10)
+//   T  = log(1/frcpa(x))/log(10)
+//   L2 = 1.0/log(10)
+//
+// So common code with two different entry points those set pointers
+// to the base address of coresponding data sets containing values
+// of L2,T and prepare integer representation of L1 needed for following
+// setf instruction.
+//
+// Note that both log and log10 use common approximation polynomial
+// it means we need only one set of coefficients of approximation.
+//
+//
+// 1. |x-1| >= 1/256
+//   InvX = frcpa(x)
+//   r = InvX*x - 1
+//   P(r) = r*((r*A3 - A2) + r^4*((A4 + r*A5) + r^2*(A6 + r*A7)),
+//   all coefficients are calculated in quad and rounded to double
+//   precision. A7,A6,A5,A4 are stored in memory whereas A3 and A2
+//   created with setf.
+//
+//   N = float(n) where n is true unbiased exponent of x
+//
+//   T is tabular value of log(1/frcpa(x)) calculated in quad precision
+//   and represented by two floating-point numbers 64-bit Thi and 32-bit Tlo.
+//   To load Thi,Tlo we get bits from 55 to 62 of register format significand
+//   as index and calculate two addresses
+//     ad_Thi = Thi_table_base_addr + 8 * index
+//     ad_Tlo = Tlo_table_base_addr + 4 * index
+//
+//   L2 (1.0 or 1.0/log(10) depending on function) is calculated in quad
+//   precision and rounded to double extended; it's loaded from memory.
+//
+//   L1 (log(2) or log10(2) depending on function) is calculated in quad
+//   precision and represented by two floating-point 64-bit numbers L1hi,L1lo
+//   stored in memory.
+//
+//   And final result = ((L1hi*N + Thi) + (N*L1lo + Tlo)) + L2*P(r)
+//
+//
+// 2. |x-1| < 1/256
+//   r = x - 1
+//   P(r) = r*((r*A3 - A2) + r^4*((A4 + r*A5) + r^2*(A6 + r*A7)),
+//   A7,A6,A5A4,A3,A2 are the same as in case |x-1| >= 1/256
+//
+//   And final results
+//     log(x)   = P(r)
+//     log10(x) = L2*P(r)
+//
+// 3. How we define is input argument such that |x-1| < 1/256 or not.
+//
+//    To do it we analyze biased exponent and integer representation of
+//    input argument
+//
+//      a) First we test is biased exponent equal to 0xFFFE or 0xFFFF (i.e.
+//         we test is 0.5 <= x < 2). This comparison can be performed using
+//         unsigned version of cmp instruction in such a way
+//         biased_exponent_of_x - 0xFFFE < 2
+//
+//
+//      b) Second (in case when result of a) is true) we need to compare x
+//         with 1-1/256 and 1+1/256 or in double precision memory representation
+//         with 0x3FEFE00000000000 and 0x3FF0100000000000 correspondingly.
+//         This comparison can be made like in a), using unsigned
+//         version of cmp i.e. ix - 0x3FEFE00000000000 < 0x0000300000000000.
+//         0x0000300000000000 is difference between 0x3FF0100000000000 and
+//         0x3FEFE00000000000
+//
+//    Note: NaT, any NaNs, +/-INF, +/-0, negatives and unnormalized numbers are
+//          filtered and processed on special branches.
