// History
//==============================================================
// 2/02/00 Initial version
// 4/04/00 Unwind support added
// 8/15/00 Bundle added after call to __libm_error_support to properly
// set [the previously overwritten] GR_Parameter_RESULT.
// 1/23/01 Set inexact flag for large args.
//
// API
//==============================================================
// float = cosh(float)
// double = cosh(double)
// long double = coshl(long double)
// input floating point f8
// output floating point f8
// Overview of operation
//==============================================================
// 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.
