* Disable ABSL_HAVE_STD_IS_TRIVIALLY_ASSIGNABLE for clang-cl.Gravatar Abseil Team2022-08-05
| | | | | | | | | The Lexan and MSVC toolchains both set _MSC_VER. The MSVC toolchain must set `ABSL_HAVE_STD_IS_TRIVIALLY_ASSIGNABLE` and `ABSL_HAVE_STD_IS_TRIVIALLY_CONSTRUCTIBLE`, in order to use Abseil workarounds in the absence of these types. This is not necessary for clang-cl. This change excludes clang-cl from the predicate setting these variables. PiperOrigin-RevId: 465589196 Change-Id: I0426ec4f844aabe7cdde5c60725f6a9a6b16479f
* Map the absl::is_trivially_* functions to their std implGravatar Abseil Team2022-08-05
| | | | | | | There's no point redefining these functions if they are supported by the compiler and the version of libstdc++. Also, some of the builtins used by the absl implementation of these functions (e.g. __has_trivial_destructor) have been deprecated in Clang 15.

* Optimize SwissMap iteration by another 5-10% for ARMGravatar Abseil Team2022-06-09
| | | | | | | | | | | | | | | | | | | https://pastebin.com/fDvgWgHe After having a chat with Dougall Johnson (https://twitter.com/dougallj/status/1534213050944802816), we realized that __clzll works with zero arguments per documentation: https://developer.arm.com/documentation/101028/0009/Data-processing-intrinsics ``` Returns the number of leading zero bits in x. When x is zero it returns the argument width, i.e. 32 or 64. ``` Codegen improves https://godbolt.org/z/ebadf717Y Thus we can use a little bit different construction not involving CLS but using more understandable CLZ and removing some operations.

* Optimize SwissMap for ARM by 3-8% for all operationsGravatar Abseil Team2022-06-06
| | | | | | | | | | | https://pastebin.com/CmnzwUFN The key idea is to avoid using 16 byte NEON and use 8 byte NEON which has lower latency for BitMask::Match. Even though 16 byte NEON achieves higher throughput, in SwissMap it's very important to catch these Matches with low latency as probing on average happens at most once. I also introduced NonIterableMask as ARM has really great cbnz instructions and additional AND on scalar mask had 1 extra latency cycle PiperOrigin-RevId: 453216147 Change-Id: I842c50d323954f8383ae156491232ced55aacb78

* | Optimize SwissMap iteration for aarch64 by 5-6%Gravatar Abseil Team2022-05-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Benchmarks: https://pastebin.com/tZ7dr67W. Works well especially on smaller ranges. After a week on spending optimizing NEON SIMD where I almost managed to make hash tables work with NEON SIMD without performance hits (still 1 cycle to optimize and I gave up a little), I found an interesting optimization for aarch64 to use cls instruction (count leading sign bits). The loop has a property that ctrl_ group is not matched against count when the first slot is empty or deleted. ``` void skip_empty_or_deleted() { while (IsEmptyOrDeleted(*ctrl_)) { uint32_t shift = Group{ctrl_}.CountLeadingEmptyOrDeleted(); ctrl_ += shift; slot_ += shift; } ... } ``` However, `kEmpty` and `kDeleted` have format of `1xxxxxx0` and `~ctrl & (ctrl >> 7)` always sets the lowest bit to 1. In naive implementation, it does +1 to start counting zero bits, however, in aarch64 we may start counting one bits immediately. This saves 1 cycle and 5% of iteration performance. Then it becomes hard to find a supported and sustainable C++ version of it. `__clsll` is not supported by GCC and was supported only since clang 8, `__builtin_clrsb` is not producing optimal codegen for clang. `__rbit` is not supported by GCC and there is no intrinsic to do that, however, in clang we have `__builtin_bitreverse{32,64}`. For now I decided to enable this only for clang, only if they have appropriate builtins. PiperOrigin-RevId: 451168570 Change-Id: I7e9256a60aecdc88ced4e6eb15ebc257281b6664

* | Exclude unsupported x64 intrinsics from ARM64EC (#1135)Gravatar Ben Niu2022-03-18
| | | | | | | | | | | | | | | | | | ARM64EC is a Microsoft-designed ARM64 ABI compatible with AMD64 applications on ARM64 Windows 11. The ARM64EC does not support _umul128 and __rdtsc as x64 intrinsics, though it provides inline function implementations for them, by emulation. Since the code already has portable code paths without using the intrinsics, instead of using the emulated intrinsic implementations, we use the said portable code paths for ARM64EC.

It inlines the UnscaledCycleClock::Now() which is a single RTDSC op for x86, and likewise inlines CycleClock::Now() for x86. The inlining should mostly have secondary benefits such as reducing spills on outlined calls. LTO may eventually hoist these functions inline for the hotspots, but it doesn't hurt to default inline this for all builds and let the compiler decide on the first pass.
