Thanks, Martin! That solves my problem.

It would have been more helpful if gcc gave me a possible cause for the
failure, similar to what clang did. Because (arguably) nowhere was I able to
figure out there is this "avx512vbmi" target feature required by the particular
instruction I used.

Just noting down the following point. I had also not added -O3 flag, which
resulted in a few more errors:

After adding -O3 flag, the code got compiled without any error.

Thanks again!
