llvm dev - Jan 2015 - [LLVMdev] list of available/valid values near an instruction

I wonder if there is a list of available/valid values (globals, constants 
arguments,..) in the scope of a given instruction?

Background:
Iterating over the instructions of a module, i would like to know which 
values are accessible in the context of the instruction, possibly replacing 
the instructions operand by a valid available other operand.


Thx
Alex

I'm not sure if I understand your question correctly, but all values 
whose definitions dominate the instruction that you are looking at are 
available.  Globals and function arguments are always available in a 
given module or function.

Hi Krzysztof
yes, they are available. What I want is to have a list of those values I can 
iterate over....
