Hi. What is purpose of introducing numbered variables kind of a.0 a.1...in pre-SSA pass, which are actually copies of local variable say a. I observed them specially in array references. In case of global variable it is fine as we have to re-read global variable and globals are treated as memory operations. Is this only purpose in case of globals??
e.g int b; //local variable array[b] = c will be translated to b.0 = b; array[b.0] = c anything to do with SSA? What if we disable them? -Seema Ravandale
