From 0d318bdffee7790eb26f94d2b50b817c5c7851b3 Mon Sep 17 00:00:00 2001 From: ChrisRackauckas Date: Tue, 26 May 2026 13:58:21 +0000 Subject: [PATCH 01/11] Unbreak Apple ARM tests that now pass MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Several `@test_broken` / `@test_skip` gates on Apple ARM (M-series) no longer apply with current LoopVectorization and the VectorizationBase nested-W=1 `_vstore_unroll!` fix. - `condstore!` masked-store tests in `ifelsemasks.jl` (lines ~626-655) now produce matching results on Apple ARM — drop the Apple branch and test unconditionally for both Float32 and Float64. - `Bernoulli_logitavx`/`Bernoulli_logit_avx` with `Vector{Bool}` and an `Int` α (`ifelsemasks.jl` line ~736) was `@test_skip`-ed but actually passes — convert to `@test`. - Issue #543 W=1 nested VecUnroll store test in `staticsize.jl` was `@test_skip`-ed for v=1 on Apple ARM; with the VectorizationBase fix it now passes for all v=1..4, n=2..8. The remaining ARM-gated breakage in `ifelsemasks.jl` (Bernoulli with a `BitVector` mask + Float64/Int α at lines ~715-722) and the `tullio_issue_131` pattern in `shuffleloadstores.jl` are deeper SIMD issues left as `@test_broken` with TODOs.

The `sub > 0` branch already applies `incr` (when not statically known) and `stride` (when ≠ 1) to scale the loop length into a byte/element offset, but the `sub == 0` branch was pushing the raw `stophint` / `stopsym` straight through. For any strided load on the unrolled axis (e.g. `arr[2i, ...]`) the cleanup bound came out `stride×` too small, so the final tail iteration was skipped whenever `looplen mod (UF*W) != 0`. On Apple ARM with W=2 for Float64, this dropped the last `out_i` iteration for every odd `out_i ≥ 3` in the tullio_issue_131 shape grid, and analogously for Float32 with W=4. The cleanup never ran for the 1–3 trailing elements, leaving them at whatever the output array was initialized to. Confirmed correct after fix for all `(M, N) ∈ 4:24 × 2:8` on the tullio reproducer; `test/shuffleloadstores.jl` goes from 4255 pass / 686 broken to 4941 pass / 0 broken on Apple M-series. Drop the matching `@test_broken` gate and the `tullio_issue_131` comment in `test/shuffleloadstores.jl`. Fixes JuliaSIMD/LoopVectorization.jl#570.

On Apple ARM the two paths can differ by a 1-ULP rounding even though `@show`-printed values look identical (the original gate predates that observation). Switch to `≈` — the test still catches anything meaningful, just not artifacts of operation reordering. 2. The BitVector `Bernoulli_logit{,_}avx` tests in `ifelsemasks.jl`, the `Vector{Bool}` + Int α variants in the same block, and the W=1 nested-VecUnroll Issue #543 testset in `staticsize.jl` all depend on the JuliaSIMD/VectorizationBase.jl#127 fixes being available at runtime. That PR isn't tagged yet, so CI's stock VectorizationBase doesn't have it and the tests fail. Restore the `Sys.ARCH === :aarch64 && Sys.isapple()` gate (as `@test_broken` / `@test_skip`) with a comment pointing at VB#127. Once that release lands and LV's compat is bumped, the branches can be dropped.
