-The first miri task that I took on was for miri to do something sensible with MIR's [`StroageLive` and `StroageDead` statements](https://github.com/solson/miri/issues/49).
-If you haven't seen these before, that's because they do not come up in Rust code; instead, `StroageLive` and `StroageDead` are inserted by the compiler.

 Liveness information is important because it is forwarded to LLVM, which then uses this information to allocate variables into stack slots.
 If two variables are never live at the same time, the compiler can assign both of them the *same* slot, which is great because it makes the stack frame smaller.

-To this end, rustc will translate `StorageLive` to [`llvm.lifetime.start`](http://llvm.org/docs/LangRef.html#llvm-lifetime-start-intrinsic) and `StroageDead` to [`llvm.lifetime.end`](http://llvm.org/docs/LangRef.html#llvm-lifetime-end-intrinsic).

 These are intrinsics that LLVM understands and takes into account when computing the layout of the stack frame.
