Sunil Pandey Nov. 24, 2021, 7:37 p.m. UTC
Implement vectorized expm1/expm1f containing SSE, AVX, AVX2 and
AVX512 versions for libmvec as per vector ABI.  It also contains
accuracy and ABI tests for vector expm1/expm1f with regenerated ulps.

+ *    exp(x) = 2^(N/2^k) * poly(R) is computed in high-low parts
+ *    expm1(x) = exp(x)-1 is then obtained via multi-precision computation

+ * ALGORITHM DESCRIPTION:
+ *   After computing exp(x) in high-low parts, an accurate computation is performed to obtain exp(x)-1
+ *   Typical exp() implementation, except that:
+ *    - tables are small (16 elements), allowing for fast gathers
+ *    - all arguments processed in the main path
+ *        - final VSCALEF assists branch-free design (correct overflow/underflow and special case responses)
+ *        - a VAND is used to ensure the reduced argument |R|<2, even for large inputs
+ *        - RZ mode used to avoid oveflow to +/-Inf for x*log2(e); helps with special case handling

+/*
+ * ALGORITHM DESCRIPTION:
+ *   After computing exp(x) in high-low parts, an accurate computation is performed to obtain exp(x)-1
+ *   Typical exp() implementation, except that:
+ *    - tables are small (32 elements), allowing for fast gathers
+ *    - all arguments processed in the main path
+ *        - final VSCALEF assists branch-free design (correct overflow/underflow and special case responses)
+ *        - a VAND is used to ensure the reduced argument |R|<2, even for large inputs
+ *        - RZ mode used to avoid oveflow to +/-Inf for x*log2(e); helps with special case handling
+ *
