-// History
-//====================================================================
-// 02/02/00 Initial version
-// 03/02/00 New Algorithm
-// 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.
-// 11/28/00 Set FR_Y to f9
-// 03/11/02 Fixed flags for fmod(qnan,zero)
-// 05/20/02 Cleaned up namespace and sf0 syntax
-// 02/10/03 Reordered header: .section, .global, .proc, .align
-// 04/28/03 Fix: fmod(sNaN,0) no longer sets errno
-//
-// API
-//====================================================================
-// double fmod(double,double);
-//
-// Overview of operation
-//====================================================================
-//  fmod(a,b)=a-i*b,
-//  where i is an integer such that, if b!=0,
-//  |i|<|a/b| and |a/b-i|<1
-//
-// Algorithm
-//====================================================================
-// a). if |a|<|b|, return a
-// b). get quotient and reciprocal overestimates accurate to
-//     33 bits (q2,y2)
-// c). if the exponent difference (exponent(a)-exponent(b))
-//     is less than 32, truncate quotient to integer and
-//     finish in one iteration
-// d). if exponent(a)-exponent(b)>=32 (q2>=2^32)
-//     round quotient estimate to single precision (k=RN(q2)),
-//     calculate partial remainder (a'=a-k*b),
-//     get quotient estimate (a'*y2), and repeat from c).
-//
-// Special cases
-//====================================================================
-// b=+/-0: return NaN, call libm_error_support
-// a=+/-Inf, a=NaN or b=NaN: return NaN
-//
-// Registers used
