If this doesn't help, you could try showing us the actual IR you're running
the transformation on.
Just FMI, is it okay to post code on this mailing list?

[LLVMdev] Identifying the instructions that uses a pointer used as a function argument
Hello all;
So here is my goal:
*** If there is a Call instruction to myFunction(int * val), I need to
identify all the instructions that uses val in the IR and replace the
uses with a newly created pointer. I will also be changing the
argument of myFunction to the new pointer.
int * val = malloc/calloc;
...
myFunction(val);
....
*val = 45;
becomes==
int * val = malloc/calloc;
int * val1 =

The PHI node preallocates its storage, so no.

[LLVMdev] Variable-length Phi-node
All,
Is it possible to create something which has the same effect of a
variable-length phi node in the C++ api. Specifically, create a phi-node
where the number of incoming values is not known at the time of its
creation.
If there is no such way of creating a phinode like that, would it be
possible to create a dummy instruction and perform a replaceAllUsesWith? If
so, what should the dummy
