// Overview of operation
//==============================================================
-// There are seven paths
-// 1. 0 < |x| < 0.25 COSH_BY_POLY
-// 2. 0.25 <=|x| < 32 COSH_BY_TBL
-// 3. 32 <= |x| < 11357.21655 COSH_BY_EXP (merged path with COSH_BY_TBL)
-// 4. |x| >= 11357.21655 COSH_HUGE
-// 5. x=0 Done with early exit
-// 6. x=inf,nan Done with early exit
-// 7. x=denormal COSH_DENORM
-//
-// For double extended we get overflow for x >= 400c b174 ddc0 31ae c0ea
-// >= 11357.21655
-//
-//
-// 1. COSH_BY_POLY 0 < |x| < 0.25
-// ===============
-// Evaluate cosh(x) by a 12th order polynomial
-// Care is take for the order of multiplication; and P2 is not exactly 1/4!,
-// P3 is not exactly 1/6!, etc.
-// cosh(x) = 1 + (P1*x^2 + P2*x^4 + P3*x^6 + P4*x^8 + P5*x^10 + P6*x^12)
-//
-// 2. COSH_BY_TBL 0.25 <= |x| < 32.0
-// =============
-// cosh(x) = cosh(B+R)
-// = cosh(B)cosh(R) + sinh(B)sinh(R)
-//
-// ax = |x| = M*log2/64 + R
-// B = M*log2/64
-// M = 64*N + j
-// We will calculate M and get N as (M-j)/64
-// The division is a shift.
-// exp(B) = exp(N*log2 + j*log2/64)
-// = 2^N * 2^(j*log2/64)
-// cosh(B) = 1/2(e^B + e^-B)
-// = 1/2(2^N * 2^(j*log2/64) + 2^-N * 2^(-j*log2/64))
-// cosh(B) = (2^(N-1) * 2^(j*log2/64) + 2^(-N-1) * 2^(-j*log2/64))
-// sinh(B) = (2^(N-1) * 2^(j*log2/64) - 2^(-N-1) * 2^(-j*log2/64))
-// 2^(j*log2/64) is stored as Tjhi + Tjlo , j= -32,....,32
-// Tjhi is double-extended (80-bit) and Tjlo is single(32-bit)
-//
-// R = ax - M*log2/64
-// R = ax - M*log2_by_64_hi - M*log2_by_64_lo
-// exp(R) = 1 + R +R^2(1/2! + R(1/3! + R(1/4! + ... + R(1/n!)...)
-// = 1 + p_odd + p_even
-// where the p_even uses the A coefficients and the p_even uses
-// the B coefficients
-//
-// So sinh(R) = 1 + p_odd + p_even -(1 -p_odd -p_even)/2 = p_odd
-// cosh(R) = 1 + p_even
-// cosh(B) = C_hi + C_lo
-// sinh(B) = S_hi
-// cosh(x) = cosh(B)cosh(R) + sinh(B)sinh(R)
-//
-// 3. COSH_BY_EXP 32.0 <= |x| < 11357.21655 ( 400c b174 ddc0 31ae c0ea )
-// ==============
-// Can approximate result by exp(x)/2 in this region.
-// Y_hi = Tjhi
-// Y_lo = Tjhi * (p_odd + p_even) + Tjlo
-// cosh(x) = Y_hi + Y_lo
-//
-// 4. COSH_HUGE |x| >= 11357.21655 ( 400c b174 ddc0 31ae c0ea )
-// ============
-// Set error tag and call error support
-//
-//
+// There are four paths
+
+// 1. |x| < 0.25 COSH_BY_POLY
+// 2. |x| < 32 COSH_BY_TBL
+// 3. |x| < 2^14 COSH_BY_EXP
+// 4. |x| >= 2^14 COSH_HUGE
+
+// For paths 1, and 2 SAFE is always 1.
+// For path 4, Safe is always 0.
+// SAFE = 1 means we cannot overflow.
