I see this error with meson when compiling softnic for octeontx2:

-c ../drivers/net/softnic/rte_eth_softnic_action.c
{standard input}: Assembler messages:
{standard input}:16: Error: selected processor does not support `crc32cx w3,w3,x0'
{standard input}:38: Error: selected processor does not support `crc32cx w1,w1,x3'

{standard input}:69: Error: selected processor does not support `crc32cx w2,w2,x3'
...

I have seen it too. Fix is here

Snippet from cover letter:

v7 Changes:

- Some compiler needs the following depended patch to compile with
meson
