--- Comment #2 from Segher Boessenkool  ---
The indexed attribute, like most attributes, is mostly used for the
scheduling descriptions currently, and isn't set on most insns, only
the ones where it makes a difference (and sometimes not those either;
patches welcome).

If you want to be *sure* what addressing something uses, you already
have that available: just look at the RTL itself!

The VSX instructions load scalar from memory and splat into the register are
another class of x-form only memory instructions that would need the indexed
insn attribute set.
