Subject: [PATCH][BZ #18740] Fix for SSE vector math tests run on non SSE4.1
	machines
To: libc-alpha <libc-alpha@sourceware.org>

Hi,

we can build SSE vector math tests with -msse2 because ifunc in vector
function itself selects SSE2 or SSE4 implementation to test.

2015-07-30  Andrew Senkevich  <andrew.senkevich@intel.com>

        [BZ #18740]
        * sysdeps/x86_64/fpu/Makefile (double-vlen2-arch-ext-cflags,
        float-vlen4-arch-ext-cflags): Use -msee2 instead of -msse4.
---
WBR,
Andrew
