Register Allocation Question.

Subject: Register Allocation Question.

Hello Everyone,
    I have a question regarding the register allocation steps in GCC. I
am creating an hypothetical example to make things easy.
 
    My processor has 2 set of register fiels with 1-16 in Class1 and
16-32 in class 2
 
    Let's say I have an RTL X with destination register R1, But if I
want to schedule this RTL to Class2.  What can I do? I see that GCC
doesn't change the register number if it already holds a hard-register.
 
Any help is highly appreciated.
 
Please CC me in your response since I am not a subscribed member.
 
Thanks,
 
Balaji V. Iyer.
