v1.2.0

A high-performance SIMD library that leverages ifunc resolvers for automatic runtime dispatch. Write portable code that automatically uses the best SIMD instructions available on your CPU.

Key features:

• Automatic CPU feature detection at program startup
• Runtime dispatch using ifunc resolvers (GCC & Clang)
• Support for SSE2, SSE4.2, AVX, AVX2, and AVX-512F
• Thread-safe SIMD level detection
• Both shared and static libraries
• C23 and C++17+ compatible

💻 Usage

Example program:

#include <dynemit.h>  // Includes core + all features

int main(void) {
    const char **features = dynemit_features();
    printf("Available features:\n");
    for (int i = 0; features[i] != NULL; i++) {
        printf("  - %s\n", features[i]);
    }
    
    simd_level_t level = detect_simd_level();
    printf("SIMD level: %s\n", simd_level_name(level));
    
    float a[1024], b[1024], result[1024];
    add_f32(a, b, result, 1024);
    mul_f32(a, b, result, 1024);
    sub_f32(a, b, result, 1024);
    
    double data[1024];
    double avg = mean_f64(data, 1024);
    double var = variance_f64(data, 1024);
    
    return 0;
}
