Re: [patch] SPARC VIS instructions or PR1820


    You shouldn't use % when the two alternatives are identical.
    All you are doing is wasting time in reload.

I agree, but it might be a good idea to change that in reload, which ought
to be able to quickly see if they are identical.  That way, if the alternatives
are ever changed to be different, there isn't the (large) risk of forgetting
to put back the %.  And the documentation really does say to use % for
commutative.  I'll put this on my (low-priority) list.
