[LLVMdev] Is LLVM expressive enough to represent asynchronous exceptions?
...ll impact on compile time. Up to 10% for some passes. Much of the overhead is in isel, which doesn't make sense to me. We should get a speedup, but we may be suffering from extra DAG bloat for the copy nodes at block boundaries.
The regalloc slowdown is also counterintuitive to me. But the way GreedyRA works today, I think the small blocks force it into a more exhaustive search for split points. This could be managed.
I didn't notice a significant score change in either case, though that's not really what I was interested in.
