optimised LLVM IR
I'm using the C++ LLVM API, and also setting -warn-stack-size=0, so any stack
usage greater than zero bytes should give me a warning (via a callback).
However I get not warning from the attached code.
This looks like a bug since the function f_int64_ uses 64 bytes of stacks
space.
Platform LLVM 6.0, Linux x64
