I get that code generation for GCC 11.4.0 and before.

For GCC 12.1.0 and above I get:
```
        movl    8(%esp), %ecx
        bswap   %ecx
        movl    %ecx, %eax
        movl    4(%esp), %ecx
        bswap   %ecx
        movl    %ecx, %edx
        movl    12(%esp), %ecx
        movl    %eax, (%ecx)
        movl    %edx, 4(%ecx)
        ret
```

Which just has a few extra moves.

But adding  -mno-sse, GCC 12 produces worse code.
