Hi Ondra I attached results as below: 1) gcc-test-memcpy-output: it compares memcpy files including your memcpy_new, memcpy_sse2_unaligned, memcpy_ssse3_back, memcpy_ssse3, memcpy_vzeroupper_avx2(I added vzeroupper instruction to memcpy_avx2), and memcpy_avx2. the format is from gcc test-memcpy.c 2) results-no-vzeroupper.tar.bz2,: it outputs comparison results including memcpy_avx2 without vzeroupper as you suggested. 3) results-vzeroupper.tar.bz2,: it outputs comparison results including memcpy_vzeroupper_avx2 as you suggested. Any questions please let me know. Thanks Ling 2013/6/6, OndÅej BÃlka <neleai@seznam.cz>: > On Wed, Jun 05, 2013 at 09:49:30PM +0800, Ling Ma wrote: >> Hi OndÅej BÃlka, >> >> We have downloaded "kam.mff.cuni.cz/~ondra/memcpy_profile.tar.bz2" and >> run the benchmark without any modification as you suggested .
