Hi Andrew,

thanks for the prompt and insightful answer. I'll use vpopc.m then.

PS. You probably already have the current vector length in a GPR, and that quantity is probably the more appropriate thing to compare against than VLMAX.  So you probably don't need to go to the trouble of materializing VLMAX.

Indeed, my question was motivated while looking at some code that operates on whole registers but it can definitely be generalised to any vector length.

Kind regards,
