This patch adds infrastructure for addition of SIMD declarations for math functions in math.h. Added new headers math-vector.h (only generic version for now) and libm-simd-decl-stubs.h with empty definitions required for proper unfolding of new macros __MATHCALL_VEC which will be used for declaration of vector math functions. 2015-05-14 Andrew Senkevich <andrew.senkevich@intel.com> * bits/math-vector.h: New file. * bits/libm-simd-decl-stubs.h: New header. * math/Makefile (headers): Added new header libm-simd-decl-stubs.h. * math/math.h (__MATHCALL_VEC): New macro. 2015-05-14 14:26:49 +00:00			`/* Platform-specific SIMD declarations of math functions.`
