--- Comment #3 from Kenneth Graunke <kenneth at whitecape.org> ---
I would really like to understand the issue - changing from implicit to
explicit seems like it's papering over a bug.  Usually in cases like this, I
try to track down the problem by disabling optimizations and seeing if that
fixes it.

I found out that disabling constant propagation into the MULs that write the
accumulator fixes the problem.  Which is pretty specific.  But the assembly
after the optimization looks just as valid...
