[PATCH 1/N] x86_64 vectorization support: vectorized math functions addition to Glibc

[Andrew Senkevich]

Hi all,

this is the first patch in the series of patches which will add Intel
vectorized math functions to Glibc.

This is addition of only one function - cos vectorized with AVX2
instructions, vector length is 4.
We plan to add at first stage cos, sin, sincos, exp, log, pow.

Changes in math library testsuite at the moment in work and will be
presented soon.
Also changes in ABI document will be prepared.

Any comments are welcome!
