vir-simd 0.3.1

This is a bugfix release.

What's Changed

• Fix clang support by @mattkretz in #21

Full Changelog: v0.3.0...v0.3.1

vir-simd 0.3.0

Features

• P0350 SIMD execution policy
• P2664 SIMD permutations

Features from Vc are finally coming back to stdx::simd (or rather vir-simd)...

• type vectorization meta-function (vir::simdize, similar to Vc::simdize)
• (de)interleave optimizations for efficient AoS (array of struct) access

What's Changed

• Improved documentation @mattkretz in #11
• CMake project and CI refactor by @AlvaroFS in #15
• Add vir::simd_permute following P2664 by @mattkretz in #13
• Add SIMD execution policy for standard algorithms by @mattkretz in #16 and #17

New Contributors

• @AlvaroFS made their first contribution in #15

Full Changelog: v0.2.0...v0.3.0

vir-simd 0.2.0

What's Changed

• Always provide simd_mask cast overloads by @mattkretz in #7
• Add vir::iota_v<simd> by @mattkretz in #8
• Add vir::cvt by @mattkretz in #9

Full Changelog: v0.1.0...v0.2.0

vir-simd 0.1.0

This is the first release of vir-simd, a header-only library to make the use of std::experimental::simd from the Parallelism TS 2 easier.

This release contains:

• A full implementation of ISO/IEC TS 19570:2018 Programming Languages — Technical Specification for C++ Extensions for Parallelism Section 9 "Data-Parallel Types".
• A mechanism to use the libstdc++ implementation transparently, when available.
• Extensions on top of stdx::simd:
  • additional casts
  • std::bitset and stdx::simd_mask conversions
  • bitwise operators for floating-point simd
  • simd concepts
  • micro-benchmarking helper functions specifically for stdx::simd
  • a preview of simdize type transformation
