Where does CodeWarrior keep rsp values?

Question

I am assembly debugging C code in Codewarrior. It assigns the value I defined with int to a location with rsp. for example:

//C code                    //Assembly code
int a = 80;                 li r9,80 
int b = 45;                 stw r9, 8(rsp) 
                            li r9,45 
                            stw r9, 12(rsp) 

Also what is 8(rsp) and 12(rsp)? How can i see these two values ​​on compiler? Thanks in advance for your answers.
