Problem with Label Constant

[nitin jain <nitin_mbm at yahoo dot com>]

Hi,

I just starts understanding the RTL format. I have a
problem with "Label Constant" ex.(LC0)

When i give the following c program as input to gcc
with the command 'gcc -dr test.c'.
----------------------------------------------------
main(){
        int x,y;
        float m,n,a,b;

        x=y=9;
        if(x==y){
                x=6;
                m=x;
        }
        else{
                y=3;
                n=y;
        }
        a=b=6.5;
        if(x<56);
        if(x>56);
        m=n=6.5;
}
---------------------------------------------------
This is the RTL output
;; Function main
-
-
-
(insn 45 42 47 (set (reg:SF 45)
        (mem/u/f:SF (symbol_ref/u:SI ("*.LC0")) 0)) -1
(nil)(nil))
-
-
-
-
(insn 60 57 62 (set (reg:SF 46)
        (mem/u/f:SF (symbol_ref/u:SI ("*.LC0")) 0)) -1
(nil)(nil))

-
-----------------------------------------------------
So in this output what is the meaning of ("*.LC0") and
why the same thing is repeated at both places.

So reply the solution or give some URL which gives the
detail.

Thanks in advance.
