[libre-riscv-dev] GPU design

[Jacob Lifshay]

Luke,

What do you think of me building a proof of concept register allocator for
my idea for sharing the int and fp register files? I'd estimate that it
would take about 2-4 days of work.

If it works well, we could reuse the architecture in the actual llvm
backend when we get around to writing that.

I'm assuming that register allocation is what you think will be most of the
compiler problems that you're nervous about.
