-//*********************************************************************
-//
-// History: 
-// 02/02/00 hand-optimized
-// 04/04/00 Unwind support added
-// 06/20/00 new version
-// 08/15/00 Bundle added after call to __libm_error_support to properly
-//          set [the previously overwritten] GR_Parameter_RESULT.
-// 05/20/02 Cleaned up namespace and sf0 syntax
-// 02/10/03 Reordered header: .section, .global, .proc, .align
-// 04/17/03 Added missing mutex directive
-//
-//*********************************************************************
-//                           ___________
-// Function:   hypot(x,y) = |(x^2 + y^2) = for double precision values
-//             x and y
-//             Also provides cabs functionality.
-//
-//*********************************************************************
-//
-// Resources Used:
-//
-//    Floating-Point Registers: f8  (Input and Return Value)
-//                              f9  (Input)
-//                              f6 -f15, f32-f34
-//
-//    General Purpose Registers:
-//      r2,r3,r29 (Scratch)
-//      r32-r36 (Locals)
-//      r37-r40 (Used to pass arguments to error handling routine)
-//
-//    Predicate Registers:      p6 - p10
-//
-//*********************************************************************
-//
-// IEEE Special Conditions:
-//
-//    All faults and exceptions should be raised correctly.
-//    Overflow can occur.
-//    hypot(Infinity and anything) = +Infinity
-//    hypot(QNaN and anything) = QNaN
-//    hypot(SNaN and anything ) = QNaN
-//
-//*********************************************************************
-//
-// Implementation:
-//  x2 = x * x   in double-extended
-//  y2 = y * y   in double-extended
-//  temp = x2 + y2   in double-extended
-//  sqrt(temp) rounded to double
