+// History
+//==============================================================
+// 02/01/02 Initial version
+// 02/18/02 Large arguments processing routine is excluded.
+// External interface entry points are added
+// 02/26/02 Added temporary return of results in r8, r9
+// 03/13/02 Corrected restore of predicate registers
+// 03/19/02 Added stack unwind around call to __libm_cisf_large
+// 09/05/02 Work range is widened by reduction strengthen (2 parts of Pi/16)
+// 02/10/03 Reordered header: .section, .global, .proc, .align
+
+// API
+//==============================================================
+// 1) float _Complex cisf(float)
+// 2) void sincosf(float, float*s, float*c)
+// 3) __libm_sincosf - internal LIBM function, that accepts
+// argument in f8 and returns cosine through f8, sine through f9
+
+//
+// Overview of operation
+//==============================================================
+//
+// Step 1
+// ======
+// Reduce x to region -1/2*pi/2^k ===== 0 ===== +1/2*pi/2^k where k=4
+// divide x by pi/2^k.
+// Multiply by 2^k/pi.
+// nfloat = Round result to integer (round-to-nearest)
+//
+// r = x - nfloat * pi/2^k
+// Do this as (x - nfloat * HIGH(pi/2^k)) - nfloat * LOW(pi/2^k) for increased accuracy.
+// pi/2^k is stored as two numbers that when added make pi/2^k.
+// pi/2^k = HIGH(pi/2^k) + LOW(pi/2^k)
+// HIGH part is rounded to zero, LOW - to nearest
+//
+// x = (nfloat * pi/2^k) + r
+// r is small enough that we can use a polynomial approximation
+// and is referred to as the reduced argument.
+//
+// Step 3
+// ======
+// Take the unreduced part and remove the multiples of 2pi.
+// So nfloat = nfloat (with lower k+1 bits cleared) + lower k+1 bits
+//
+// nfloat (with lower k+1 bits cleared) is a multiple of 2^(k+1)
+// N * 2^(k+1)
+// nfloat * pi/2^k = N * 2^(k+1) * pi/2^k + (lower k+1 bits) * pi/2^k
+// nfloat * pi/2^k = N * 2 * pi + (lower k+1 bits) * pi/2^k
+// nfloat * pi/2^k = N2pi + M * pi/2^k
+//
+//
+// Sin(x) = Sin((nfloat * pi/2^k) + r)
+// = Sin(nfloat * pi/2^k) * Cos(r) + Cos(nfloat * pi/2^k) * Sin(r)
+//
+// Sin(nfloat * pi/2^k) = Sin(N2pi + Mpi/2^k)
+// = Sin(N2pi)Cos(Mpi/2^k) + Cos(N2pi)Sin(Mpi/2^k)
+// = Sin(Mpi/2^k)
+//
+// Cos(nfloat * pi/2^k) = Cos(N2pi + Mpi/2^k)
+// = Cos(N2pi)Cos(Mpi/2^k) + Sin(N2pi)Sin(Mpi/2^k)
+// = Cos(Mpi/2^k)
+//
+// Sin(x) = Sin(Mpi/2^k) Cos(r) + Cos(Mpi/2^k) Sin(r)
+//
+//
+// Step 4
+// ======
+// 0 <= M < 2^(k+1)
+// There are 2^(k+1) Sin entries in a table.
+// There are 2^(k+1) Cos entries in a table.
+//
+// Get Sin(Mpi/2^k) and Cos(Mpi/2^k) by table lookup.
+//
+//
+// Step 5
+// ======
+// Calculate Cos(r) and Sin(r) by polynomial approximation.
+//
+// Cos(r) = 1 + r^2 q1 + r^4 q2 = Series for Cos
+// Sin(r) = r + r^3 p1 + r^5 p2 = Series for Sin
+//
+// and the coefficients q1, q2 and p1, p2 are stored in a table
+//
+//
+// Calculate
+// Sin(x) = Sin(Mpi/2^k) Cos(r) + Cos(Mpi/2^k) Sin(r)
+//
+// as follows
+//
+// S[m] = Sin(Mpi/2^k) and C[m] = Cos(Mpi/2^k)
+// rsq = r*r
+//
+//
+// P = p1 + r^2p2
+// Q = q1 + r^2q2
+//
+// rcub = r * rsq
+// Sin(r) = r + rcub * P
+// = r + r^3p1 + r^5p2 = Sin(r)
+//
+// P = r + rcub * P
+//
+// Answer = S[m] Cos(r) + C[m] P
+//
+// Cos(r) = 1 + rsq Q
+// Cos(r) = 1 + r^2 Q
+// Cos(r) = 1 + r^2 (q1 + r^2q2)
+// Cos(r) = 1 + r^2q1 + r^4q2
+//
+// S[m] Cos(r) = S[m](1 + rsq Q)
+// S[m] Cos(r) = S[m] + S[m] rsq Q
+// S[m] Cos(r) = S[m] + s_rsq Q
+// Q = S[m] + s_rsq Q
+//
+// Then,
+//
+// Answer = Q + C[m] P
