[LLVMdev] struct returns
...observations:
1. Is there a good way to retrieve the current target limitations on
struct return sizes?
2. The sretpromotion pass does not take struct size limitations into
account; it will happily convert an sret parameter with five members
into a return value that llc chokes on.
3. There is no sretdemotion pass.
4. If the answer to #1 is "no", perhaps we need platform-specific
sretpromotion and sretdemotion passes to allow small struct returns to
happen efficiently while large struct returns can be successfully
codegen'd, all without having to build such platform-specific
knowledge...
