As far as LLVM is concerned, the memory has no structure, it's just a blob.I suspect LLVM's optimization passes won't particularly care for that approach.That's fine. We've already done the CSE and alias analysis on the thing. And as mentioned, trying to turn overlapping (or partial) accesses into some "named accesses" is just *wrong*. They weren't named in the C code either. They are accesses through pointer arithmetic. Trying to make them be somehow named would just be crazy.
LLVM just cares about layout.It does not care about naming (or lack thereof). Nobody/nothing is trying to make them named.
