Detailed Description

Compile-time SIMD policy selection for vectorized operations.

This header provides policy classes for SIMD operations that are selected at compile time based on the target platform. This eliminates runtime branching overhead and enables full compiler optimization.

Usage:

// Default usage - automatically uses best policy for platform
simd_ops<> ops;
float result = ops.sum_floats(data, count);
 
// Explicit policy (for testing or special cases)
simd_ops<scalar_simd_policy> scalar_ops;
