| 2026-02-14 21:00:47 +0100 | <int-e> | `vector` makes at least one SIMD-unfriendly design choice though: `drop` is O(1) so there's no alignment guaranteee beyond the primitive data type for unboxed vectors. |

| 2026-02-14 21:00:09 +0100 | <int-e> | Hmm, https://minoki.github.io/posts/2025-01-13-ghc-simd.html looks like a decent overview of the state of the SIMD primitives in GHC? |
| 2026-02-14 20:58:30 +0100 | <tomsmeding> | no that's not quite right |
| 2026-02-14 20:57:35 +0100 | <tomsmeding> | and 13-17 for 9.10 and higher |
| 2026-02-14 20:56:56 +0100 | <tomsmeding> | seems LLVM 12 will do for 9.0 up to and including 9.8 |
| 2026-02-14 20:55:11 +0100 | <int-e> | subtle |
| 2026-02-14 20:53:27 +0100 | <tomsmeding> | I wonder if the maintainer of the playground could be bribed to make -fllvm work there. |
| 2026-02-14 20:50:15 +0100 | <tomsmeding> | will the work be suitably arranged? That depends on the vagaries of the code generator, as well as the implementation of V.imapM_ |
| 2026-02-14 20:49:56 +0100 | <tomsmeding> | GHC will not generate SIMD instructions here, but if the work is suitably arranged, LLVM will do it |
| 2026-02-14 20:49:35 +0100 | <tomsmeding> | probie: if you're talking about LLVM, then the only real answer is to try it :p |

| 2026-02-14 20:43:55 +0100 | <probie> | If I just do something like `V.imapM_ (\ix a -> (a +) <$> V.read y ix) x` will it work? |
| 2026-02-14 20:38:28 +0100 | <probie> | Dumb question: what's the correct way to do `x += y` with a mutable unboxed vector such that it'll generate SIMD instructions (when using the LLVM backend)? |
