[LLVMdev] Aggregate store/load optimization
Hi all, One area where LLVM suck pretty badly is aggregate store and loads. clang do not use them so there are not seen as important, and aren't handled nicely. Other frontends work around the issue as it is not handled properly and we ends up with some kind of chicken and egg issue. I recently proposed a diff to be able to optimize load from aggregate stores in GVN without great success.
