Jake Weinstein 04d99df80d libc: ARM: Add 32-bit Kryo memcpy ... * Memcpy is based on Scorpion due to Qualcomm's 128-bit cache line size optimizations. * PLDOFFSET and PLDSIZE are from the ARM64 Kryo memcpy routine. Below are the results of the benchmark, tested on a OnePlus 3 with MSM8996. Before: BM_string_memcpy/8 1000k 8 0.934 GiB/s BM_string_memcpy/64 1000k 11 5.785 GiB/s BM_string_memcpy/512 1000k 25 19.918 GiB/s BM_string_memcpy/1024 50M 42 23.938 GiB/s BM_string_memcpy/8Ki 10M 473 17.291 GiB/s BM_string_memcpy/16Ki 5M 565 28.976 GiB/s BM_string_memcpy/32Ki 1000k 1105 29.631 GiB/s BM_string_memcpy/64Ki 1000k 2194 29.864 GiB/s After: BM_string_memcpy/8 1000k 6 1.145 GiB/s BM_string_memcpy/64 1000k 7 8.560 GiB/s BM_string_memcpy/512 1000k 18 27.370 GiB/s BM_string_memcpy/1024 50M 33 30.340 GiB/s BM_string_memcpy/8Ki 10M 266 30.770 GiB/s BM_string_memcpy/16Ki 5M 553 29.599 GiB/s BM_string_memcpy/32Ki 1000k 1121 29.219 GiB/s BM_string_memcpy/64Ki 1000k 2208 29.678 GiB/s Test: make otapackage Test: Ran bionic unit tests on Pixel device.
