DUB package intel-intrinsics is out in version v1.13.0.
Now with support for all AVX and AVX2 intrinsics.
- Supported: SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, BMI2, AVX,
AVX2
- Target x86, x86_64, arm64, arm32. All intrinsics have
emulation/alt paths.
- DMD, LDC, or GDC
Congratulations! Very nice to have this package.
Now: should you use AVX for consumer software in D?
I would say - yes as much as you can! If it is not AVX512, but
AVX and AVX2 could be applied.
Maybe the flow could be started with auto-vec for simpler code
maintenance.
But nowadays, AVX(2) is supported pretty widely I think.
Projects for inspiration could be taken from Lemire and Ash.
Their projects SIMD-powered used in other consumer products.
simdutf, simdjson, usearch and others

- The reach isn't very good, very nascent support on Microsoft
Prism and Apple Rosetta.
- In arm, neon vectors are 128-bit anyway.
- You will encounter: https://github.com/dlang/dub/issues/3080
(unless using redub or --combined)
Probably separate ARM targeted arm-intrinsics package could be
created with targeting:
- NEON
- SVE
- SVE2
