[3/N,x86_64] Vectorized math functions
Commit Message
Hi,
here is the last change regarding to libm-test.inc: addition of method
for separation which exactly testing function needed to run with help
of generated during make check header with series of conditional
definitions.
ChangeLog
2014-11-20 Andrew Senkevich <andrew.n.senkevich@gmail.com>
* math/libm-test.inc (HAVE_VECTOR): New macros.
* math/Makefile b/math/Makefile: Added generation of
libm-have-vector-test.h.
* math/gen-libm-have-vector-test.sh: Script generates series
of macros for condition in testing functions.
Attached the same.

Rather than hardcoding this, I think it would be better to base it on the
output of "grep 'START.*;$' libm-test.inc" (with a comment that once all
functions use ALL_RM_TEST instead of using START directly, this code can
be removed).

Comments need to end with ". ".
