--- Comment #3 from Andrew Stubbs <ams at gcc dot gnu.org> --- I did see these, but I hadn't had time to chase them up. The proposed patch is exactly the sort of solution I was expecting to find, short term. Have you confirmed that it fixes all the cases? A proper solution is to find out how to implement reductions with the RDNA ISA, of course, but that's probably non-trivial (as in, I'm pretty sure it's more than renaming a few mnemonics), and low-priority as GCC does a reasonably good job without them.
