Hello Everyone,
I am currently working with Gcc 4.0.2 and I have a question
regarding the register allocation.
I saw that regclass() function determines which class of register
the registers in the current units should be assigned to. The question I
have is: Will this decision change in any other parts of the compiler?
or is this this the final place where they fix the register class? So,
if I add my own priority-based register-class assigner, can I just
replace this function and add my own?
Any help is very very much appreciated. Please feel free to contact me
if you need any additional clarification.
Thanks,
Balaji V. Iyer.
