...s not used in the callee and replaced it with undef at the callsite. This breaks the dynamic lookup. (I really don't want to get into a discussion of whether this is the "right" way to implement such a thing. This approach has various advantages, but more importantly, it's a _reasonable_ runtime design. In my view, LLVM should be able to support any reasonable design, regardless of whether it's the best one or not.) The proposal ----------------- We add a new parameter attribute which can be placed either on a call site (call, invoke), or function declaration. The exact...

I'm thinking about ways to improve the Xen balloon driver. This is the driver which allows the guest domain to expand or contract by either asking for more memory from the hypervisor, or giving unneeded memory back. From the kernel's perspective, it simply looks like a driver which allocates and frees pages; when it allocates memory it gives the underlying physical page back to the
