SSA names

[ranjith kumar]

Hi,
   The  SSA names are represented as i.xyz_abc... 
For example D.2204_50
What is the singnificanse of 2204 and 50?
What information can we get from that variable name?

Also let b[50] be an int array declared in a .c
program.
In PHI nodes it is referred as b_6.
But b_6 is not used any where else.
References to b[] are done by b[D.2204_50] but not
with b_6.
Why so?

Where can I found more information about gcc's SSA
repesentaion??
I got gcc's internal documentation file. Very less
information is given.

Thanks in advance.
