List some possible TODO/discussion about the SIMD feature: - Is it make sense to `enable the SIMD feature by default` [1]? I noticed that [servo/pathfinder](https://github.com/servo/pathfinder/blob/master/simd/Cargo.toml) enables SIMD by default. - Change static configure to `dynamic CPU feature detection`, [core::arch dynamic-cpu-feature-detection](https://doc.rust-lang.org/core/arch/index.html#dynamic-cpu-feature-detection) explains. [1] Quote from https://en.wikipedia.org/wiki/SIMD: `Small-scale (64 or 128 bits) SIMD became popular on general-purpose CPUs in the early 1990s and continued through 1997 and later with Motion Video Instructions (MVI) for Alpha. SIMD instructions can be found, to one degree or another, on most CPUs` ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
