[LLVMdev] Explicit Dependence in LLVM IR

[kapil anand]

Hi,

I have a question regarding addition of explicit dependencies between two
things in LLVM IR. Suppose I have following code:

%a = alloca i32
......
store 10, i32* %a
call foo()

Is there any way of adding an explicit dependence between the call to foo
and the store? Can I add some dependence to represent that this call might
access the previous store and any pass should not optimize it away.

Thanks
