Dear All,
I am seeking endorsement for review of my library int128 [1]. The library requires only C++14, is header only, and has no mandatory dependencies. What does int128 provide? Two portable and performant types: a 128-bit signed integer and a 128-bit unsigned integer, as well as a standard library for them. The performance of these types have been tuned and tested on a variety of architectures to include: x64, x32, s390x, ARM64, ARM32, PPC64LE. Both of the types and most of their library functions also work inside CUDA kernels. Benchmarks against Boost.Multiprecision, Absl, MSVC's software 128- bit integers, and built-ins, are available [2].
I endorse this library.
Thank you Peter. Arnaud Bechler has graciously offered to manage the review, so we will get this on the calendar in short order. Matt
