The instruction set contains SIMD vector instructions which operate on multiple values contained in one large register at the same time.
2022/2/23 -This looks like a perfect candidate for SIMD but looking at the assembly in godbolt using gcc 11.2 -O3, it doesn't look like it uses SIMD instructions.
2023/12/8 -Most commonly used contemporary CPUs support some SIMD instructions, which allow processing of multiple data by a single instruction.
gcc has recently gained intrinsic support for some SIMD operations whereby the coder requests a vector of specified dimension and content, and then performs ...
2024/2/16 -The following code produces assembly that conditionally executes SIMD in GCC 12.3 when compiled with -O3. For completeness, the code always executes SIMD in ...

The most low-level way to use SIMD is to use the assembly vector instructions directly — they aren't different from their scalar equivalents at all — but we ...
