// History
//==============================================================
// 2/02/00: Initial version
// 4/13/00: Improved speed
// 4/19/00: Removed the qualifying predicate from the fmerge.s that
// takes the absolute value.
// 6/16/00: Reassigned FP registers to eliminate stalls on loads
// 8/30/00: Saved 5 cycles in main path by rearranging large argument logic
// and delaying use of result of fcmp in load by 1 group
//
// API

// double atan( double x);
//
// Overview of operation
//==============================================================
// atan(x) = sign(X)pi/2 - atan(1/x)
//
// We have two paths: |x| > 1 and |x| <= 1
//
// |x| > 1
// ==========================================
//
// c = frcpa(x) which is approximately 1/x
//
// xc = 1- B
// B = 1-xc
//
// Approximate 1/(1-B)^k by a polynomial in B, poly(B)
// k is 45.
//
// poly(B) = 1 + r1 B + r2 B^2 + ...+ r10 B^10
//
// c^k = (1-B)^k/x^k
// c^k/(1-B)^k = 1/x^k
// c^k poly(B) = 1/x^k
// poly(x) = series(atan(1/x)) = 1/x - 1/3x^3 + 1/5x^5 - 1/7x^7 .... + 1/45 x^45
// = 1/x^45 ( x^44 - x^42/3 + x^40/5 - x^38/7 ... +1)
// = 1/x^45 ( y^22 - y^21/3 + y^20/5 - y^19/7 ... +1)
//
// = c^45 poly(B) poly(x)
// = c^45 r(B) q(y)
// q(y) = q0 + q1 y + q2 y^2 + ... + q22 y^22
// where q22 is 1.0
// atan(x) = sign(X)pi/2 - c^45 r(B) q(y)
// |x| <= 1
// ==========================================
// poly(x) = series(atan(x)) = x - x^3/3 + x^5/5 + .....
// poly(x) = series(atan(x)) = x + x^3(- 1/3 + x^2/5 + ..... +x^47/47)
// poly(x) = series(atan(x)) = x + x^3(p0 + x^2/5 + ..... + x^44/47)
