XieJiSS 8b1df101da fix: build on risc-v (#9215 An error occurred ) ... Summary: Patch is modified from ~~https://reviews.llvm.org/file/data/du5ol5zctyqw53ma7dwz/PHID-FILE-knherxziu4tl4erti5ab/file~~ Tested on Arch Linux riscv64gc (qemu) UPDATE: Seems like the above link is broken, so I tried to search for a link pointing to the original merge request. It turned out to me that the LLVM guys are cherry-picking from `google/benchmark`, and the upstream should be this: 808571a52f/src/cycleclock.h (L190) Pull Request resolved: https://github.com/facebook/rocksdb/pull/9215 Reviewed By: siying, jay-zhuang Differential Revision: D34170586 Pulled By: riversand963 fbshipit-source-id: 41b16b9f7f3bb0f3e7b26bb078eb575499c0f0f4		3 years ago
