Hi Diego,

What I'd like is to be able to find out which object code location a SSA-labelled variable goes to, for debugging.  Similar to in gdb, like using 'info line' for function names.  But for SSA-labelled variables.  

So if there are two versions of 'int A' by the SSA step, A_1 and A_2:  I could find out A_1 is at 0x63e4 and A_2 is 0x6350.

I'd be grateful for a suggested method for a way to do this, even if there isn't one already...

Thanks,
Lori
