Sorry I'm late to the party here, but would it make sense to write this as:

(?:smp|virt)_(?:$smp_barrier_stems)

Yes.  Perhaps the name might be better as barrier_stems.

Also, ideally this would be longest match first or use \b
after the matches so that $all_barriers could work
successfully without a following \s*\(

my $all_barriers = qr{
	(?:smp|virt)_(?:barrier_stems)|
	$barriers)
}x;

or maybe add separate $smp_barriers and $virt_barriers

<shrug>  it doesn't matter much in any case

OK just to clarify - are you OK with merging the patch as is?
Refactorings can come as patches on top if required.
