Re: Annotations in tree

I am not sure if I unerstand ...can you elaborate please ? So what  I
need is if I identify say a reference a[i] inside a loop, I want to
identify the corresponding RTL. What I find now is that
these get transformed for example 
             D.1065_17 = a_matrix[i_24][k_30];   // I have identified this 
             sum_12 = D.1065_17 + sum_31;

gets coalesced back into 
            sum = a_matrix[i][k] + sum;  before it is expaned into rtl.. 
How do I keep track that it is indeed the same array reference though
it has gone through some transformation. ( One another tranformation
is generating a pointer to it instead of using the array).
