If x is an integer variable i.e., int x; -> %x=alloca i32
I want to insert an instruction %add = &(%x) into my IR code through a pass.
Is this possible by GEP instruction or any other means? I mean, %add = gep(x).
My Initial IR,
%i = alloca i32, align 4
store volatile i32 50, i32* %i, align 4
for a C code
i=50;
I want to write a pass from which I get a modified IR like below,
Modified IR,
%i = alloca i32, align 4
store volatile i32 50, i32* %i, align 4
%i_addr = (Get address of i)
Thanks and appreciate the help :)

%i is already the address of the variable i -- you can see its type is i32*, which is a pointer. To get the value of i (50 in your example) you would need a load instruction.
