Luis is working on address cost adjustments among other things, so I
guess the path of leas

I still don't like the idea of disabling a whole class of instructions in the
md file.
It seems much better to adjust the costs here so that you get most of the
improvement now, and fine tune it once we can differentiate between
loads and stores.
Taking your example, adding -funroll

Hi,
Here's v3 of the patch to disable register offset addressing mode for
stores of 128-bit values on Falkor because they're very costly.
Following Kyrill's suggestion, I compared the codegen for a53 and
found that the codegen was quite different. Jim's original patch is
the most minimal compromi
