* Fixes many compilation issues that come from having no external CIGravatar Derek Mauro2022-11-30
| | | | | | | | | | | | | | | | | | coverage of the accelerated CRC implementation and some differences bewteen the internal and external implementation. This change adds CI coverage to the linux_clang-latest_libstdcxx_bazel.sh script assuming this script always runs on machines of at least the Intel Haswell generation. Fixes include: * Remove the use of the deprecated xor operator on crc32c_t * Remove #pragma unroll_completely, which isn't known by GCC or Clang: https://godbolt.org/z/97j4vbacs * Fixes for -Wsign-compare, -Wsign-conversion and -Wshorten-64-to-32 PiperOrigin-RevId: 491965029 Change-Id: Ic5e1f3a20f69fcd35fe81ebef63443ad26bf7931

* Release the CRC libraryGravatar Derek Mauro2022-11-09
This implementation can advantage of hardware acceleration available on common CPUs when using GCC and Clang. A future update may enable this on MSVC as well. PiperOrigin-RevId: 487327024 Change-Id: I99a8f1bcbdf25297e776537e23bd0a902e0818a1
