Hi, Yes SCEV is pretty limited on this aspect. This kind of code can trigger LLVM to explode in time/memory: https://llvm.org/bugs/show_bug.cgi?id=18606 <https://llvm.org/bugs/show_bug.cgi?id=18606> See also this llvm-dev thread: SCEV implementation and limitations, do we need "pow"? : http://lists.llvm.org/pipermail/llvm-dev/2014-February/070062.html CC: Sanjoy who may have an

> Why do you care about the size of library files? I assumed dynamic libraries and static libraries were similar in size, but I just checked some of my own static libraries and they are indeed much larger than the executables they compile to.
