Hi,
Do you mean you support unaligned access to any DImode regular type (int64_t) ?

Hi,
On my target, SCmode is 4 byte aligned. But to load it into
a register, it must be 8byte aligned. I can handle misaligned
load in backend. But IRA generates misaligned load directly
when SCmode is accessed as DImode. How can I tell IRA to use
misaligned load for DImode?
Thanks.
