This commit adds optimized cased for less_vec memset case that uses the avx512vl/avx512bw mask store avoiding the excessive branches. test-memset and test-wmemset are passing. Signed-off-by: Noah Goldstein --- Tests where run on the following CPUs: Icelake: https://ark.intel.com/content/www/us/en/ark/products/196597/intel-core-i7-1065g7-processor-8m-cache-up-to-3-90-ghz.html Tigerlake: https://ark.intel.com/content/www/us/en/ark/products/208921/intel-core-i7-1165g7-processor-12m-cache-up-to-4-70-ghz-with-ipu.html All times are the geometric mean of N=20. The unit of time is seconds. "Cur" refers to the current implementation "New" refers to this patches implementation There are 3 cases that matter for performance. 1) ptr is not within VEC_SIZE of a page 2) ptr is within VEC_SIZE of a page but length is small enough so that there is not page cross 3) page cross. Case 1 (which should be the most common) the new implementation has a near universal improvement. The only exception is the avx512 case for size = [0, 15] where I believe the downclocking from avx512 is causing slowdown. Its worth noting that because bench-memset.c repeats the same size the branch heavy case should be favored as the branches will all be predicted correctly. In a setting with unpredictable length this version should perform significant better. For example I implemented something similiar to this change for memmove/memcpy and saw ~40% speedup in bench-memcpy-random (but for other reasons this change isnt good there). Cases 2 has a slowdown with this patch (roughly equivilent to the performance improvement for case 1). Though I think this is probably less important than the improvements for case 1 as page cross are probably rarer than non-page cross. Case 3 has a very slight slowdown with this patch. But for the same reason as above I think this patch is still an improvement. Its worth noting that the page cross check could be removed and the mask store implementation would still be correct, but I'm finding the the fault suppression is incredibly expensive from a performance perspective and without the branch I see a 2 orders of magnitude performance regression on the Case 2 benchmarks.
