-//*********************************************************************
-// 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.
-// 05/20/02 Cleaned up namespace and sf0 syntax
-// 02/10/03 Reordered header: .section, .global, .proc, .align
-//
-//*********************************************************************
-//
-// Function:   Combined sqrtf(x), where
-//                         _
-//             sqrtf(x) = |x, for single precision x values
-//
-//********************************************************************
-//
-// Accuracy:       Correctly Rounded 
-//
-//********************************************************************
-//
-// Resources Used:
-//
-//    Floating-Point Registers: f8  (Input and Return Value)
-//                              f7 -f14
-//
-//    General Purpose Registers:
-//      r32-r36 (Locals)
-//      r37-r40 (Used to pass arguments to error handling routine)
-//
-//    Predicate Registers:      p6, p7, p8
-//
-//********************************************************************
-//
-// IEEE Special Conditions:
-//
-//    All faults and exceptions should be raised correctly.
-//    sqrtf(QNaN) = QNaN
-//    sqrtf(SNaN) = QNaN
-//    sqrtf(+/-0) = +/-0 
-//    sqrtf(negative) = QNaN and error handling is called
-//
-//********************************************************************
-//
-// Implementation:
-//
-//  Modified Newton-Raphson Algorithm
