在CGo中，确定环境是否支持AVX-512的正确方法是什么？

func cpuid(eaxArg, ecxArg uint32) (eax, ebx, ecx, edx uint32) {
    asm := func(eaxArg, ecxArg uint32) (eax, ebx, ecx, edx uint32)
    {
        eax, ebx, ecx, edx := 0, 0, 0, 0
        asm volatile(
            "cpuid":
            "=a"(eax), "=b"(ebx), "=c"(ecx), "=d"(edx):
            "a"(eaxArg), "c"(ecxArg):
        )
        return eax, ebx, ecx, edx
    }
    return asm(eaxArg, ecxArg)
}

func hasAVX512Support() bool {
    _, _, ecx, _ := cpuid(7, 0)
    return ecx&(1<<16) != 0
}

#include <stdio.h>

extern int hasAVX512Support();

int main() {
    if (hasAVX512Support()) {
        printf("The environment supports AVX-512.\n");
    } else {
        printf("The environment does not support AVX-512.\n");
    }
    return 0;
}
