File vector-finite-math-aliases.patch of Package glibc.i686.4524
2015-12-03 Andrew Senkevich <andrew.senkevich@intel.com> * math/Makefile ($(inst_libdir)/libm.so): Corrected path to libmvec_nonshared.a 2015-11-27 Andrew Senkevich <andrew.senkevich@intel.com> [BZ #19058] * math/Makefile ($(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.
