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.
