+// 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.
+// 10/12/00 Update to set denormal operand and underflow flags
+// 1/22/01  Fixed to set inexact flag for small args.
+//
+// API
+//==============================================================
+// double = sinh(double)
+// input  floating point f8
+// output floating point f8
+//
+// Registers used
+//==============================================================
+// general registers: 
+// r32 -> r47
+// predicate registers used:
+// p6 p7 p8 p9
+// floating-point registers used:
+// f9 -> f15; f32 -> f45; 
+// f8 has input, then output
+//
+// Overview of operation
+//==============================================================
+// There are four paths
+// 1. |x| < 0.25        SINH_BY_POLY
+// 2. |x| < 32          SINH_BY_TBL
+// 3. |x| < 2^14        SINH_BY_EXP
+// 4. |x_ >= 2^14       SINH_HUGE
+//
+// For double extended we get infinity for x >= 400c b174 ddc0 31ae c0ea
+//                                           >= 1.0110001.... x 2^13
+//                                           >= 11357.2166
+//
+// But for double we get infinity for x >= 408633ce8fb9f87e
+//                                      >= 1.0110...x 2^9
+//                                      >= +7.10476e+002
+//
+// And for single we get infinity for x >= 42b3a496
+//                                      >= 1.0110... 2^6
+//                                      >= 89.8215
+//
+// SAFE: If there is danger of overflow set SAFE to 0
+//       NOT implemented: if there is danger of underflow, set SAFE to 0
+// SAFE for all paths listed below
+//
+// 1. SINH_BY_POLY
+// ===============
+// If |x| is less than the tiny threshold, then clear SAFE 
+// For double, the tiny threshold is -1022 = -0x3fe => -3fe + ffff = fc01
+//             register-biased, this is fc01
+// For single, the tiny threshold is -126  = -7e    => -7e  + ffff = ff81
+// If |x| < tiny threshold, set SAFE = 0
+//
+// 2. SINH_BY_TBL
+// =============
+// SAFE: SAFE is always 1 for TBL; 
+//
+// 3. SINH_BY_EXP
+// ==============
+// There is a danger of double-extended overflow   if N-1 > 16382 = 0x3ffe
+// r34 has N-1; 16382 is in register biased form, 0x13ffd
+// There is danger of double overflow if N-1 > 0x3fe
+//                       in register biased form, 0x103fd
+// Analagously, there is danger of single overflow if N-1 > 0x7e
+//                       in register biased form, 0x1007d
+// SAFE: If there is danger of overflow set SAFE to 0
+//
+// 4. SINH_HUGE
+// ============
+// SAFE: SAFE is always 0 for HUGE
