llvm dev - Jun 2013 - [LLVMdev] Getting the memory address of all operands on an expression

In short if suppose i have some expression as a=b+c-d*e,  and with the help
of LLVM pass i want to make a string like this:-    

"[Hexadecimal address of 'b'] [opcode of +] [Hexadecimal address of
'c']
[opcode of -] [Hexadecimal address of 'd'] [opcode of *] [Hexadecimal
address of 'e']".

Than how can i make it................

You can't, because addresses are only known at run-time, while passes are
run at
compile time.  If you are running the program using the JIT then you can try to
extract the info at run-time from the internal JIT data structures.

Ciao, Duncan.

Actually I want to pass this string as an argument to a function (let say it
will just print it in on stdout), and this function will be called before
every store instruction at runtime.
