If they've made non-trivial changes, translating back into LLVM IR can involve reverse-engineering the structure of the addressing in order to fit it into the -static type of the original first operand. It isn't always possibly to fully +static type of the original first operand. It isn't always possible to fully reconstruct this structure; sometimes the underlying addressing doesn't correspond with the static type at all. In such cases the optimizer instead will -emit a GEP with the base pointer casted to a simple address-unit pointer, using +emit a GEP with the base pointer cast to a simple address-unit pointer, using the name "uglygep". This isn't pretty, but it's just as valid, and it's sufficient to preserve the pointer aliasing guarantees that GEP provides. |
