through the nullptr (often a run-time check) • Every access through a subscripted pointer is in-range (often a run-time check) • That • Implies range checking and elimination of dangling pointers (“memory safety”) • Some heuristics • Many rely on static analysis • Some beyond our current tools • Often easy to check “mechanically” • Primarily for tools (static analysis) • To allow specific feedback to programmer abstraction with sufficient data to range check • E.g., vector and span • void f(span s, int x) { s[x] = 7; } // OK for a checking span • Run-time range check every subscript operation • E.g., vector

that rarely happens in practice. Polymorphic Inline Caches record what actual types are seen, and check against the common cases at runtime. It’s a cute optimization which tries to make the language’s paper itself adds fast algorithms for escape analysis, automatic object inlining, and array bounds check elimination. Where HotSpot is really amazing is in putting all of these things together in a very complex and memory to unlock new superpowers. Folks are used to Valgrind as a use-after-free our out-of-bounds tool, but that’s just one of Valgrind’s many capabilities. The true feat of Valgrind is its tooling

types: coroutine_handle<>, coroutine_handle • coroutine_handle<>: resume/destroy coroutine, check status(done) • coroutine_handle: provide access to the promise object(promise) Useful to string” or in general co_await on some un-awaitable expressions. Or prohibit co_await on certain types. Check out Promise::await_transform co_await is … Awaitable is … Awaiter is … At the compile time, when Wait(); } Okay, go back to our save world mission, feel like so far, we are only writing some empty check. We need to stop and do something practical, since we don’t have much time left. 105106 106 GOAL
