// History:
// 02/02/00 (Hand Optimized)
// 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.
// 01/22/01 Corrected results for powl(1,inf), powl(1,nan), and
//          powl(snan,0) to be 1 per C99, not nan.  Fixed many flag settings.
// 02/06/01 Call __libm_error support if over/underflow when y=2.
// 04/17/01 Support added for y close to 1 and x a non-special value.
//          Shared software under/overflow detection for all paths
// 02/07/02 Corrected sf3 setting to disable traps
// 05/13/02 Improved performance of all paths
// 02/10/03 Reordered header: .section, .global, .proc, .align;
//          used data8 for long double table values
// 04/17/03 Added missing mutex directive
// 10/13/03 Corrected .endp names to match .proc names

//  Special Cases
//
//    If Y = 2,    return X*X.
//    If Y = 0.5,  return sqrt(X).

//  Compute log(X) to extra precision.

//  ker_log_80( X, logX_hi, logX_lo, Safe );
//
//   ...logX_hi + logX_lo approximates log(X) to roughly 80
//   ...significant bits of accuracy.
//
//  Compute Y*log(X) to extra precision.
//
//    P_hi := Y * logX_hi
//    P_lo := Y * logX_hi - P_hi       ...using FMA
//    P_lo := Y * logX_lo + P_lo       ...using FMA
//
//  Compute exp(P_hi + P_lo)

//       take necessary precaution in computing
//       scale*Z_hi + (scale*Z_lo)
//       to set possible exceptions correctly.
//    End If
//
//  Case_Y_Special
//
//   ...Follow the order of the case checks
//
//   If Y is +-0, return +1 without raising any exception.
//   If Y is +1,  return X  without raising any exception.
//   If Y is qNaN, return Y without exception.
//   If X is qNaN, return X without exception.
//
//   At this point, X is real and Y is +-inf.
//   Thus |X| can only be 1, strictly bigger than 1, or
//   strictly less than 1.
//
//   If |X| < 1, then
//   return ( Y == +inf?  +0 : +inf )

//   goto Case_Invalid
//
//  Case_X_Special
//
//   ...Follow the order of the case checks
//   ...Note that Y is real, finite, non-zero, and not +1.
//
//   If X is qNaN, return X without exception.
//
//   If X is +-0,
//   return ( Y > 0 ? +0 : +inf )
//
//   If X is +inf
//   return ( Y > 0 ? +inf : +0 )
//
//   If X is -inf
//   return -0 ** -Y
//   return ( Y > 0 ? +inf : +0 )
//
//  Case_Invalid
//
//   Return 0 * inf to generate a quiet NaN together
//   with an invalid exception.
//
//  Implementation
//  ==============
//
//   We describe the quick branch since this part is important
//   in reaching the normal case efficiently.
//
//  STAGE 1
//  -------
//   This stage contains two threads.
//
//   Stage1.Thread1
//
//     fclass.m   X_excep,  X_ok   = X, (NatVal or s/qNaN) or
//                              +-0, +-infinity
//
//     fclass.nm  X_unsupp, X_supp = X, (NatVal or s/qNaN) or
//                              +-(0, unnorm, norm, infinity)
//
//     X_norm := fnorm( X ) with traps disabled
//
//     If (X_excep)  goto Filtering (Step 2)
//     If (X_unsupp) goto Filtering (Step 2)
//
//     Stage1.Thread2
//     ..............
//
//     fclass.m   Y_excep,  Y_ok   = Y, (NatVal or s/qNaN) or
//                              +-0, +-infinity
//
//     fclass.nm  Y_unsupp, Y_supp = Y, (NatVal or s/qNaN) or
//                              +-(0, unnorm, norm, infinity)
//
//     Y_norm := fnorm( Y ) with traps disabled
//
//     If (Y_excep)  goto Filtering (Step 2)
//     If (Y_unsupp) goto Filtering (Step 2)
//
//
//  STAGE 2
//  -------
//  This stage contains two threads.
//
//     Stage2.Thread1
//     ..............
//
//     Set X_lt_0 if X < 0 (using fcmp)
//     sgn := +1.0
//     If (X_lt_0) goto Filtering (Step 2)
//
//     Stage2.Thread2
//     ..............
//
//     Set Y_is_1 if Y = +1 (using fcmp)
//     If (Y_is_1) goto Filtering (Step 2)
//
//   STAGE 3
//   -------
//   This stage contains two threads.
//
//
//   Stage3.Thread1
//   ..............
//
//     X := fnorm(X) in prevailing traps
//
//
//     Stage3.Thread2
//     ..............
//
//     Y := fnorm(Y) in prevailing traps
//
//   STAGE 4
//   -------
//
//   Go to Case_Normal.

// 3fff b8aa 3b29 5c17 f0bc
// For speed the significand will be loaded directly with a movl and setf.sig
//   and the exponent will be bias+63 instead of bias+0.  Thus subsequent
//   computations need to scale appropriately.
// The constant 2^12/ln(2) is needed for the computation of N.  This is also
//   obtained by scaling the computations.
//
// Two shifting constants are loaded directly with movl and setf.d.
//   1. RSHF_2TO51 = 1.1000..00 * 2^(63-12)
//        This constant is added to x*1/ln2 to shift the integer part of
//        x*2^12/ln2 into the rightmost bits of the significand.
//        The result of this fma is N_signif.
//   2. RSHF       = 1.1000..00 * 2^(63)
//        This constant is subtracted from N_signif * 2^(-51) to give
//        the integer part of N, N_fix, as a floating-point number.
//        The result of this fms is float_N.
