The context is:

int
com64(Node *n)
{
	...
		switch(n->op) {
		default:
			diag(n, "unknown vlong %O", n->op);
		case OFUNC:
			n->complex = FNX;
		case ORETURN:
		case OAS:
		case OIND:
		case OLIST:
		case OCOMMA:
			return 1;
		case OADD:
			a = nodaddv;
			goto setbop;
		case OSUB:
	...
}

and it seems to me that a better answer would be to change the error
message to something like:

	"undefined 64-bit operation: %O"

I can't see much reason to stick to vlong when it is clear that 64-bit
handling is involved.

I do wonder why 8c isn't plagued by the same problem.
