Yes, well aware of that.
We at SAP are maintaining an in memory database and therefore need LLVM (at least the IR generating part) not to crash or leak in case of OOMs. We have local patches that ensure that, as well as OOM tests. However, we only able to upstream parts of those patches (like this one) because of the restrictions you mentioned. But this helps us to keep the number of required patches low.
