-// History
-//==============================================================
-// 02/02/00 Initial version 
-// 04/04/00 Unwind support added
-// 08/15/00 Bundle added after call to __libm_error_support to properly
-//          set [the previously overwritten] GR_Parameter_RESULT.
-// 01/23/01 Set inexact flag for large args.
-// 05/07/01 Reworked to improve speed of all paths
-// 05/20/02 Cleaned up namespace and sf0 syntax
-// 12/06/02 Improved performance
-//
-// API
-//==============================================================
-// long double = coshl(long double)
-// input  floating point f8
-// output floating point f8
-//
-// Registers used
-//==============================================================
-// general registers: 
-// r14 -> r40
-// predicate registers used:
-// p6 -> p11
-// floating-point registers used:
-// f9 -> f15; f32 -> f90; 
-// f8 has input, then output
-//
-// 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
-//
-//
-// Assembly macros
