Over the last few weeks we (Google) have been discussing ideas on how to
leverage the LTO work to implement a whole program optimizer that is
both fast and scalable.
While we do not have everything thought out in detail, we think we have
enough to start doing some implementation work. I tried a

Yes.
Not
When I returned to the computer this morning, the repack was
completed... with a 1.3GB pack instead.
So... The gcc repo apparently really needs a large window to efficiently
compress those large objects.
So, am I right that if you have a very well-done pack (such as gcc's),
you might want

So doesn't the question then become "Why isn't reload reloading the constant
into a register"?

Hi Revital1,
Thank you very much for your help. The ISA I am using
(OpenRISC) does not provide an alternative for moving a constant into
memory. The only way of doing this is to move the constant into a
register (which i am doing) and then move that register value into
memory. So what can

I think you should add the pair of constraints m and I respectively to
the description of the instruction in your md file (and a relevant
case 8 to handle such instruction), i.e.:
