* RocksDB CRC32c optimization with ARMv8 Intrinsic (#5221) Summary: 1. Add Arm linear crc32c implemtation for RocksDB. 2. Arm runtime check for crc32 Pull Request resolved: https://github.com/facebook/rocksdb/pull/5221 Differential Revision: D15013685 Pulled By: siying fbshipit-source-id: 2c2983743d26656d93f212dc7c1a3cf66a1acf12 * Support rocksdbjava aarch64 build and test (#5258) Summary: Verified with an Ampere Computing eMAG aarch64 system. Pull Request resolved: https://github.com/facebook/rocksdb/pull/5258 Differential Revision: D15807309 Pulled By: maysamyabandeh fbshipit-source-id: ab85d2fd3fe40e6094430ab0eba557b1e979510d * Cleanup the Arm64 CRC32 unused warning (#5565) Summary: When 'HAVE_ARM64_CRC' is set, the blew methods: - bool rocksdb::crc32c::isSSE42() - bool rocksdb::crc32c::isPCLMULQDQ() are defined but not used, the unused-function is raised when do rocksdb build. This patch try to cleanup these warnings by add ifndef, if it build under the HAVE_ARM64_CRC, we will not define `isSSE42` and `isPCLMULQDQ`.

This patch removes this invalid assert. Closes: https://github.com/facebook/rocksdb/issues/4277 Pull Request resolved: https://github.com/facebook/rocksdb/pull/5836 Differential Revision: D17532470 fbshipit-source-id: ca98078ecbc6a9416c69de3bd6ffcfa33a0f0185 * Fix naming of library on PPC64LE (#6080) Summary: **NOTE**: This also needs to be back-ported to be 6.4.6 Fix a regression introduced in f2bf0b2 by https://github.com/facebook/rocksdb/pull/5674 whereby the compiled library would get the wrong name on PPC64LE platforms. On PPC64LE, the regression caused the library to be named `librocksdbjni-linux64.so` instead of `librocksdbjni-linux-ppc64le.so`. This PR corrects the name back to `librocksdbjni-linux-ppc64le.so` and also corrects the ordering of conditional arguments in the Makefile to match the expected order as defined in the documentation for Make.
