[llvm-dev] How to pass a StringRef to a function call inserted as instrumentation?

[Dipanjan Das via llvm-dev]

I am wriitng an LLVM pass to insert instrumentation at certain points of
the program. I want to pass the `StringRef` obtained from `getName()` as a
parameter to a function `func(char* s)`. I can allocate some space on stack
using `AllocaInst` to generate an `alloca` instruction. But, how can I copy
the `StringRef` to the stack space?
