Gcc x86 instrinsics support

Has anyone tried to use AVX intrinsics on CARC? I am using gcc-8.3.0 on CARC and using “-march=native”, but gcc says is does not support x86 intrinsics, which is quite unlikely for high performance cluster.
Here is what I did:

#include <inttypes.h>
#include <stdio.h>
#include <x86intrin.h>

int main(void) {
    printf("%" PRIu32 "\n", _mm_crc32_u32(42, 2534474250));
    return 0;
}

The command I used:

$ gcc -march=native test.c

I think I figured it out.
I had to remove modul ‘nvidia-hpc-sdk’.
It works after removing that module.
