Lu" To: GNU C Library Subject: [PATCH] x86-64: Verify that _dl_runtime_resolve preserves vector registers Message-ID: <20170207195721.GA23532@intel.com> Reply-To: "H.J. Lu" MIME-Version: 1.0 Content-Disposition: inline User-Agent: Mutt/1.7.1 (2016-10-04) On x86-64, _dl_runtime_resolve must preserve the first 8 vector registers. Add 3 _dl_runtime_resolve tests to verify that SSE, AVX and AVX512 registers are preserved. Tested on SSE, AVX and AVX512 machines with GCC 6. Any comments? H.J. --- * sysdeps/x86_64/Makefile (tests): Add tst-sse, tst-avx and tst-avx512. (test-extras): Add tst-avx-aux and tst-avx512-aux. (extra-test-objs): Add tst-avx-aux.o and tst-avx512-aux.o.
