libmvec_nonshared.a
2015-11-27 Andrew Senkevich <andrew.senkevich@intel.com>
[BZ #19058]
* math/Makefile ($(inst_libdir)/libm.so): Added libmvec_nonshared.a to
AS_NEEDED.
* sysdeps/x86/fpu/bits/math-vector.h: Removed code with asm aliases
workaround.
* sysdeps/x86_64/fpu/Makefile (libmvec-support,
libmvec-static-only-routines): Added new file.
* sysdeps/x86_64/fpu/svml_finite_alias.S: New file.
* NEWS: Mention this fix.
