-// History
-//==============================================================
-// 02/02/00 Initial version
-// 02/03/00 Added p12 to definite over/under path. With odd power we did not
-// maintain the sign of x in this path.
-// 04/04/00 Unwind support added
-// 04/19/00 pow(+-1,inf) now returns NaN
-// pow(+-val, +-inf) returns 0 or inf, but now does not call error
-// support
-// Added s1 to fcvt.fx because invalid flag was incorrectly set.
-// 08/15/00 Bundle added after call to __libm_error_support to properly
-// set [the previously overwritten] GR_Parameter_RESULT.
-// 09/07/00 Improved performance by eliminating bank conflicts and other stalls,
-// and tweaking the critical path
-// 09/08/00 Per c99, pow(+-1,inf) now returns 1, and pow(+1,nan) returns 1
-// 09/28/00 Updated NaN**0 path
-// 01/20/01 Fixed denormal flag settings.
-// 02/13/01 Improved speed.
-// 03/19/01 Reordered exp polynomial to improve speed and eliminate monotonicity
-// problem in round up, down, and to zero modes. Also corrected
-// overflow result when x negative, y odd in round up, down, zero.
-// 06/14/01 Added brace missing from bundle
-// 12/10/01 Corrected case where x negative, 2^52 <= |y| < 2^53, y odd integer.
-// 12/20/01 Fixed monotonity problem in round to nearest.
-// 02/08/02 Fixed overflow/underflow cases that were not calling error support.
-// 05/20/02 Cleaned up namespace and sf0 syntax
-// 08/29/02 Improved Itanium 2 performance
-// 09/21/02 Added branch for |y*log(x)|<2^-11 to fix monotonicity problems.
-// 02/10/03 Reordered header: .section, .global, .proc, .align
-// 03/31/05 Reformatted delimiters between data tables

-// double pow(double x, double y)
-//
-// Overview of operation
-//==============================================================
-//
-// Three steps...
-// 1. Log(x)
-// 2. y Log(x)
-// 3. exp(y log(x))
-//
-// This means we work with the absolute value of x and merge in the sign later.
-// Log(x) = G + delta + r -rsq/2 + p
-// G,delta depend on the exponent of x and table entries. The table entries are
-// indexed by the exponent of x, called K.
-//
-// The G and delta come out of the reduction; r is the reduced x.
-//
-// B = frcpa(x)
-// xB-1 is small means that B is the approximate inverse of x.
-//
-// Log(x) = Log( (1/B)(Bx) )
-// = Log(1/B) + Log(Bx)
-// = Log(1/B) + Log( 1 + (Bx-1))
-//
-// x = 2^K 1.x_1x_2.....x_52
-// B= frcpa(x) = 2^-k Cm
-// Log(1/B) = Log(1/(2^-K Cm))
-// Log(1/B) = Log((2^K/ Cm))
-// Log(1/B) = K Log(2) + Log(1/Cm)
-//
-// Log(x) = K Log(2) + Log(1/Cm) + Log( 1 + (Bx-1))
-//
-// If you take the significand of x, set the exponent to true 0, then Cm is
-// the frcpa. We tabulate the Log(1/Cm) values. There are 256 of them.
-// The frcpa table is indexed by 8 bits, the x_1 thru x_8.
-// m = x_1x_2...x_8 is an 8-bit index.
-//
-// Log(1/Cm) = log(1/frcpa(1+m/256)) where m goes from 0 to 255.
-//
-// We tabluate as two doubles, T and t, where T +t is the value itself.
-//
-// Log(x) = (K Log(2)_hi + T) + (Log(2)_hi + t) + Log( 1 + (Bx-1))
-// Log(x) = G + delta + Log( 1 + (Bx-1))
-//
-// The Log( 1 + (Bx-1)) can be calculated as a series in r = Bx-1.
-//
-// Log( 1 + (Bx-1)) = r - rsq/2 + p
-//
-// Then,
-//
-// yLog(x) = yG + y delta + y(r-rsq/2) + yp
-// yLog(x) = Z1 + e3 + Z2 + Z3 + (e2 + e3)
-//
-//
-// exp(yLog(x)) = exp(Z1 + Z2 + Z3) exp(e1 + e2 + e3)
-//
-//
-// exp(Z3) is another series.
-// exp(e1 + e2 + e3) is approximated as f3 = 1 + (e1 + e2 + e3)
-//
-// Z1 (128/log2) = number of log2/128 in Z1 is N1
-// Z2 (128/log2) = number of log2/128 in Z2 is N2
-//
-// s1 = Z1 - N1 log2/128
-// s2 = Z2 - N2 log2/128
-//
-// s = s1 + s2
-// N = N1 + N2
-//
-// exp(Z1 + Z2) = exp(Z)
-// exp(Z) = exp(s) exp(N log2/128)
-//
-// exp(r) = exp(Z - N log2/128)
-//
-// r = s + d = (Z - N (log2/128)_hi) -N (log2/128)_lo
-// = Z - N (log2/128)
-//
-// Z = s+d +N (log2/128)
-//
-// exp(Z) = exp(s) (1+d) exp(N log2/128)
-//
-// N = M 128 + n
-//
-// N log2/128 = M log2 + n log2/128
-//
-// n is 8 binary digits = n_7n_6...n_1
-//
-// n log2/128 = n_7n_6n_5 16 log2/128 + n_4n_3n_2n_1 log2/128
-// n log2/128 = n_7n_6n_5 log2/8 + n_4n_3n_2n_1 log2/128
-// n log2/128 = I2 log2/8 + I1 log2/128
-//
-// N log2/128 = M log2 + I2 log2/8 + I1 log2/128
-//
-// exp(Z) = exp(s) (1+d) exp(log(2^M) + log(2^I2/8) + log(2^I1/128))
-// exp(Z) = exp(s) (1+d1) (1+d2)(2^M) 2^I2/8 2^I1/128
-// exp(Z) = exp(s) f1 f2 (2^M) 2^I2/8 2^I1/128
-//
-// I1, I2 are table indices. Use a series for exp(s).
-// Then get exp(Z)
-//
-// exp(yLog(x)) = exp(Z1 + Z2 + Z3) exp(e1 + e2 + e3)
-// exp(yLog(x)) = exp(Z) exp(Z3) f3
-// exp(yLog(x)) = exp(Z)f3 exp(Z3)
-// exp(yLog(x)) = A exp(Z3)
-//
-// We actually calculate exp(Z3) -1.
-// Then,
-// exp(yLog(x)) = A + A( exp(Z3) -1)
-//
-
-// Table Generation
-//==============================================================
-
-// The log values
-// ==============
-// The operation (K*log2_hi) must be exact. K is the true exponent of x.
-// If we allow gradual underflow (denormals), K can be represented in 12 bits
-// (as a two's complement number). We assume 13 bits as an engineering
-// precaution.
-//
-// +------------+----------------+-+
-// | 13 bits | 50 bits | |
-// +------------+----------------+-+
-// 0 1 66
-// 2 34
-//
-// So we want the lsb(log2_hi) to be 2^-50
-// We get log2 as a quad-extended (15-bit exponent, 128-bit significand)
-//
-// 0 fffe b17217f7d1cf79ab c9e3b39803f2f6af (4...)
-//
-// Consider numbering the bits left to right, starting at 0 thru 127.
-// Bit 0 is the 2^-1 bit; bit 49 is the 2^-50 bit.
-//
-// ...79ab
-// 0111 1001 1010 1011
-// 44
-// 89
-//
-// So if we shift off the rightmost 14 bits, then (shift back only
-// the top half) we get
-//
-// 0 fffe b17217f7d1cf4000 e6af278ece600fcb dabc000000000000
-//
-// Put the right 64-bit signficand in an FR register, convert to double;
-// it is exact. Put the next 128 bits into a quad register and round to double.
-// The true exponent of the low part is -51.
-//
-// hi is 0 fffe b17217f7d1cf4000
-// lo is 0 ffcc e6af278ece601000
-//
-// Convert to double memory format and get
-//
-// hi is 0x3fe62e42fefa39e8
-// lo is 0x3cccd5e4f1d9cc02
-//
-// log2_hi + log2_lo is an accurate value for log2.
-//
-//
-// The T and t values
-// ==================
-// A similar method is used to generate the T and t values.
-//
-// K * log2_hi + T must be exact.
-//
-// Smallest T,t
-// ----------
-// The smallest T,t is
-// T t
-// 0x3f60040155d58800, 0x3c93bce0ce3ddd81 log(1/frcpa(1+0/256))= +1.95503e-003
-//
-// The exponent is 0x3f6 (biased) or -9 (true).
-// For the smallest T value, what we want is to clip the significand such that
-// when it is shifted right by 9, its lsb is in the bit for 2^-51. The 9 is the
-// specific for the first entry. In general, it is 0xffff - (biased 15-bit
-// exponent).
-
-// Independently, what we have calculated is the table value as a quad
-// precision number.
-// Table entry 1 is
-// 0 fff6 80200aaeac44ef38 338f77605fdf8000
-//
-// We store this quad precision number in a data structure that is
-// sign: 1
-// exponent: 15
-// signficand_hi: 64 (includes explicit bit)
-// signficand_lo: 49
-// Because the explicit bit is included, the significand is 113 bits.
-//
-// Consider significand_hi for table entry 1.
-//
-//
-// +-+--- ... -------+--------------------+
-// | |
-// +-+--- ... -------+--------------------+
-// 0 1 4444444455555555556666
-// 2345678901234567890123
-//
-// Labeled as above, bit 0 is 2^0, bit 1 is 2^-1, etc.
-// Bit 42 is 2^-42. If we shift to the right by 9, the bit in
-// bit 42 goes in 51.
-//
-// So what we want to do is shift bits 43 thru 63 into significand_lo.
-// This is shifting bit 42 into bit 63, taking care to retain shifted-off bits.
-// Then shifting (just with signficaand_hi) back into bit 42.
-//
-// The shift_value is 63-42 = 21. In general, this is
-// 63 - (51 -(0xffff - 0xfff6))
-// For this example, it is
-// 63 - (51 - 9) = 63 - 42 = 21
-//
-// This means we are shifting 21 bits into significand_lo. We must maintain more
-// that a 128-bit signficand not to lose bits. So before the shift we put the
-// 128-bit significand into a 256-bit signficand and then shift.
-// The 256-bit significand has four parts: hh, hl, lh, and ll.
-//
-// Start off with
-// hh hl lh ll
-// <64> <49><15_0> <64_0> <64_0>
-//
-// After shift by 21 (then return for significand_hi),
-// <43><21_0> <21><43> <6><58_0> <64_0>
-//
-// Take the hh part and convert to a double. There is no rounding here.
-// The conversion is exact. The true exponent of the high part is the same as
-// the true exponent of the input quad.
-//
-// We have some 64 plus significand bits for the low part. In this example, we
-// have 70 bits. We want to round this to a double. Put them in a quad and then
-// do a quad fnorm.
-// For this example the true exponent of the low part is
-// true_exponent_of_high - 43 = true_exponent_of_high - (64-21)
-// In general, this is
-// true_exponent_of_high - (64 - shift_value)
-//
-//
-// Largest T,t
-// ----------
-// The largest T,t is
-// 0x3fe62643fecf9742, 0x3c9e3147684bd37d log(1/frcpa(1+255/256))=+6.92171e-001
-//
-// Table entry 256 is
-// 0 fffe b1321ff67cba178c 51da12f4df5a0000
-//
-// The shift value is
-// 63 - (51 -(0xffff - 0xfffe)) = 13
-//
-// The true exponent of the low part is
-// true_exponent_of_high - (64 - shift_value)
-// -1 - (64-13) = -52
-// Biased as a double, this is 0x3cb
-//
-//
-//
-// So then lsb(T) must be >= 2^-51
-// msb(Klog2_hi) <= 2^12
-//
-// +--------+---------+
-// | 51 bits | <== largest T
-// +--------+---------+
-// | 9 bits | 42 bits | <== smallest T
-// +------------+----------------+-+
-// | 13 bits | 50 bits | |
