x86-64: Add vector exp2/exp2f implementation to libmvec
Implement vectorized exp2/exp2f containing SSE, AVX, AVX2 and AVX512 versions for libmvec as per vector ABI. It also contains accuracy and ABI tests for vector exp2/exp2f with regenerated ulps. Reviewed-by: H.J. Lu <hjl.tools@gmail.com>

||||
*
|
||||
* exp2(x) = 2^n * T[j] * (1 + P(y))
|
||||
* where
|
||||
* x = m*(1/K) + y, y in [-1/K..1/K]
|
||||
* m = n*K + j, m,n,j - signed integer, j in [-K/2..K/2]
|
||||
*
|
||||
* values of 2^j/K are tabulated
|
||||
*
|
||||
* P(y) is a minimax polynomial approximation of exp2(x)-1
|
||||
* on small interval [-1/K..1/K]
|
||||
*
|
||||
* Special cases:
|
||||
*
|
||||
* exp2(NaN) = NaN
|
||||
* exp2(+INF) = +INF
|
||||
* exp2(-INF) = 0
|

* exp2(x) = 1 for subnormals
|
||||
* For IEEE double
|
||||
* if x >= 1024.0 then exp2(x) overflows
|

* if x < -1076.0 then exp2(x) underflows

* ALGORITHM DESCRIPTION:
|
||||
*
|
||||
* exp2(x) = 2^n * T[j] * (1 + P(y))
|
||||
* where
|
||||
* x = m*(1/K) + y, y in [-1/K..1/K]
|
||||
* m = n*K + j, m,n,j - signed integer, j in [-K/2..K/2]
|
||||
*
|
||||
* values of 2^j/K are tabulated
|
||||
*
|
||||
* P(y) is a minimax polynomial approximation of exp2(x)-1
|
||||
* on small interval [-1/K..1/K]
|
||||
*
|
||||
* Special cases:
|
||||
*
|
||||
* exp2(NaN) = NaN
|
||||
* exp2(+INF) = +INF
|
||||
* exp2(-INF) = 0
|
||||
* exp2(x) = 1 for subnormals
|
||||
* For IEEE double
|
||||
* if x >= 1024.0 then exp2(x) overflows
|
||||
* if x < -1076.0 then exp2(x) underflows

*
|
||||
* Double precision mantissa represented as: 1.b1b2b3 ... b52
|
||||
* Constant for double precision: S = 2^48 x 1.5
|
||||
*
|
||||
* 2^X = 2^Xo x 2^{X-Xo}
|
||||
* 2^X = 2^K x 2^fo x 2^{X-Xo}
|
||||
* 2^X = 2^K x 2^fo x 2^r
|
||||
*
|
||||
* 2^K --> Manual scaling
|
||||
* 2^fo --> Table lookup
|
||||
* r --> 1 + poly (r = X - Xo)
|
||||
*
|
||||
* Xo = K + fo
|
||||
* Xo = K + 0.x1x2x3x4
|
||||
*
|
||||
* r = X - Xo
|
||||
* = Vreduce(X, imm)
|
||||
* = X - VRndScale(X, imm), where Xo = VRndScale(X, imm)
|
||||
*
|
||||
* Rnd(S + X) = S + Xo, where S is selected as S = 2^19 x 1.5
|
||||
* S + X = S + floor(X) + 0.x1x2x3x4
|
||||
* Rnd(S + X) = Rnd(2^48 x 1.5 + X)
|
||||
* (Note: 2^exp x 1.b1b2b3 ... b52, 2^{exp-52} = 2^-4 for exp=48)
|
||||
*
|
||||
* exp2(x) = 2^K x 2^fo x (1 + poly(r)), where 2^r = 1 + poly(r)
|
||||
*
|
||||
* Scale back:
|
||||
* dest = src1 x 2^floor(src2)

|

*
|
||||
* Single precision mantissa represented as: 1.b1b2b3 ... b23
|
||||
* Constant for single precision: S = 2^19 x 1.5
|
||||
*
|
||||
* 2^X = 2^Xo x 2^{X-Xo}
|
||||
* 2^X = 2^K x 2^fo x 2^{X-Xo}
|
||||
* 2^X = 2^K x 2^fo x 2^r
|
||||
*
|
||||
* 2^K --> Manual scaling
|
||||
* 2^fo --> Table lookup
|
||||
* r --> 1 + poly (r = X - Xo)
|
||||
*
|
||||
* Xo = K + fo
|
||||
* Xo = K + 0.x1x2x3x4
|
||||
*
|
||||
* r = X - Xo
|
||||
* = Vreduce(X, imm)
|
||||
* = X - VRndScale(X, imm), where Xo = VRndScale(X, imm)
|
||||
*
|
||||
* Rnd(S + X) = S + Xo, where S is selected as S = 2^19 x 1.5
|
||||
* S + X = S + floor(X) + 0.x1x2x3x4
|
||||
* Rnd(S + X) = Rnd(2^19 x 1.5 + X)
|
||||
* (Note: 2^exp x 1.b1b2b3 ... b23, 2^{exp-23} = 2^-4 for exp=19)
|
||||
*
|
||||
* exp2(x) = 2^K x 2^fo x (1 + poly(r)), where 2^r = 1 + poly(r)
|
||||
*
|
||||
* Scale back:
|
||||
* dest = src1 x 2^floor(src2)

* ALGORITHM DESCRIPTION:
|
||||
*
|
||||
* exp2(x) = 2^n * T[j] * (1 + P(y))
|
||||
* where
|
||||
* x = m*(1/K) + y, y in [-1/K..1/K]
|
||||
* m = n*K + j, m,n,j - signed integer, j in [-K/2..K/2]
|
||||
*
|
||||
* values of 2^j/K are tabulated
|
||||
*
|
||||
* P(y) is a minimax polynomial approximation of exp2(x)-1
|
||||
* on small interval [-1/K..1/K]
|
||||
*
|
||||
* Special cases:
|
||||
*
|
||||
* exp2(NaN) = NaN
|
||||
* exp2(+INF) = +INF
|
||||
* exp2(-INF) = 0
|
||||
* exp2(x) = 1 for subnormals
|
||||
* For IEEE float
|
||||
* if x >= 128.0 then exp2f(x) overflow
|
||||
* if x < -151.0 then exp2f(x) underflow

* ALGORITHM DESCRIPTION:
|
||||
*
|
||||
* exp2(x) = 2^n * T[j] * (1 + P(y))
|
||||
* where
|
||||
* x = m*(1/K) + y, y in [-1/K..1/K]
|
||||
* m = n*K + j, m,n,j - signed integer, j in [-K/2..K/2]
|
||||
*
|
||||
* values of 2^j/K are tabulated
|
||||
*
|
||||
* P(y) is a minimax polynomial approximation of exp2(x)-1
|
||||
* on small interval [-1/K..1/K]
|
||||
*
|
||||
* Special cases:
|
||||
*
|
||||
* exp2(NaN) = NaN
|
||||
* exp2(+INF) = +INF
|
||||
* exp2(-INF) = 0
|
||||
* exp2(x) = 1 for subnormals
|
||||
* For IEEE float
|
||||
* if x >= 128.0 then exp2f(x) overflow
|
||||
* if x < -151.0 then exp2f(x) underflow
