[LLVMdev] Proposal for safe-to-execute meta-data for heap accesses
...indirected object model (for example when implementing dynamic language heap accesses): %object = inttoptr %value %p1 = getelementptr %object, <things> %p2 = load %p1 !notrap !{ @isObject, %value } %p3 = getelementptr %p3, <more things> %v = load %p3 !notrap !{ @hasShape, %object, 0xstuff } // 0xstuff will be a compile-time constant I can’t think of any examples where you’d want to use safe-to-execute and where Hal’s rule won’t hold. -Filip > > -Hal > >> >> >> >> >> >> It's not clear how that is better than any of the other...

Instead of an SSA use, we can have meta-data that
