2026-01-28simd/archsimd: add missing cpufeature to generated mask/merge methodsDavid Chase
Change-Id: I34678f4ef17fe1b8b7657a2c3d39685b4a5951f2 Reviewed-on: https://go-review.googlesource.com/c/go/+/739981 LUCI-TryBot-Result: Go LUCI <golang-scoped@luci-project-accounts.iam.gserviceaccount.com> Reviewed-by: Cherry Mui <cherryyz@google.com>
2026-01-08simd/archsimd: rename Broadcast methodsCherry Mui
Currently the Broadcast128/256/512 methods broadcast the lowest element of the input vector to a vector of the corresponding width. There are also variations of broadcast operations that broadcast the whole (128- or 256-bit) vector to a larger vector, which we don't yet support. Our current naming is unclear which version it is, though. Rename the current ones to Broadcast1ToN, to be clear that they broadcast one element. The vector version probably will be named BoradcastAllToN (not included in this CL).

2025-12-11simd/archsimd: define ToMask only on integer vectorsCherry Mui
The ToMask method is for converting an AVX2-style mask represented in a vector to the Mask type. The AVX2-style mask is a (signed) integer, so define ToMask only on integer vectors.
