* Include immintrin.h instead of wmmintrin.h (#1015)Gravatar Stan Hu2021-09-13
| | | | | | | | | | | | | | | | | | | immintrin.h is the de-factor standard header for clang and GCC to include Intel intrinsics. Using this header avoids requiring the compiler to use the `-maes` and `-msse4.1` compiler options on systems that may not have AES or SSE instruction support. clang: As seen in https://github.com/llvm-mirror/clang/blob/master/lib/Headers/immintrin.h, specific intrinsic header files are conditionally included depending on whether the feature is available. gcc: As seen in https://github.com/gcc-mirror/gcc/blob/master/gcc/config/i386/immintrin.h, gcc includes all intrinsic header files, but each individual file guards against the feature not being available. This came out of an investigation in https://github.com/grpc/grpc/pull/27121.

On ARM, this requires a sequence of two instructions with a high combined latency and poor throughput. This change provides alternative bit-mixing code for ARM that uses only 64-bit arithmetic (multiplication, xor, and left-shifts) and speeds things up considerably. The bit-mixing code for ARM was inspired by by Woothash[1] and xxh3[1]. Once I landed on a sequence of operations that provided good mixing, I used a test harness to search for the combination of shift / rotate factors that provided the best mixing, as indicated by SMHasher hash quality tests. The new mixing code passes 13 out of 15 of the hash quality test suites in SMHasher, with the two failures being in the noise range: e.g. 1 collision vs. zero expected in a keyset of ~8m keys.

* CMake: option to use cxx_std_11 (minimum) that propagates. (#986)Gravatar Eric Barndollar2021-07-29
| | | | | | | | | See https://github.com/abseil/abseil-cpp/issues/259 for context. This change introduces the ABSL_PROPAGATE_CXX_STD option (default to OFF for now, though it prints a warning in CMake 2.8+ builds that a future Abseil release will default to ON). When enabled, all Abseil CMake targets will set the cxx_std_11 target meta feature (which will then propagate to targets that depend upon Abseil) rather than setting the target-level CXX_STANDARD property to CMAKE_CXX_STANDARD (which is the default value anyway), which doesn't propagate. Updates README documentation to clarify behavior and with a different example recommendation for library projects (which should generally leave CMAKE_CXX_STANDARD to the root application project). See https://crascit.com/2015/03/28/enabling-cxx11-in-cmake/ for a useful overview of these different CMake features surrounding C++ standard version configuration.

It’s thus potentially faster, since it doesn’t have to save and restore FPU state.

If we add support for non-power-of-two-minus-one capacities, this is the correct thing to assert. For example, consider: Group::kWidth = 8, capacity_ = 8, ctrl_ = {kEmpty, 1, 2, 3, 4, 5, 6, 7, kSentinel, kEmpty, 1, 2, 3, 4, 5, 6}. In this case, if we do an unsuccessful lookup with H2 mapping to slot 1, then the first Group will contain {1, 2, 3, 4, 5, 6, 7, kSentinel} so we need to continue to the second Group (at which point seq.index() == 8 == capacity_) to find a kEmpty. Note: this is a no-op change for now since we never have `capacity % Group::kWidth == 0`.

Especially in the ring and btree alternative code, there is a common check if a node is a 'plain' edge (EXTERNAL or FLAT), or 'something else'. This change can make that check a single branch, i.e., instead of 'tag == EXTERNAL || tag >= FLAT', we can simply check for 'tag >= EXTERNAL'. Likewise we have some cases where we check for RING, EXTERNAL or FLAT, so we align RING + 1 with EXTERNAL.

The subsequent cast to int discards the excess precision.
