[LLVMdev] Interprocedural Register Allocation

I have been interested in compilers, especially in the optimization
quite some time now. I don't know if I have a decent background to brag
all I can say is that I have tried very small things related to building a
However I admit that I am still new to a lot of things.
Like many others who are interested in compilers, I am interested in the
Allocation problem too. I have been thinking about implementing an
register allocator from quite a while now. But I thought instead of trying
it out on a
toy compiler, why not just get my hands dirty in the real world. I was
seeing if I
could implement it on LLVM and incidentally, I noticed that the open
lists interprocedural register allocation as one of the open projects .
However, I was reading the DeveloperPolicy page and the policy for making
changes asks the developers to discuss the work here before proceeding. So,
writing this mail to kickoff a discussion. I would really like to
contribute to LLVM and
I think this is a good place for me to start. Is there something specific
like a paper
that you guys would want me to read before diving in?
I understand that register allocation itself is a tricky problem and doing
allocation is extremely hard. But I would like to try, at least try and
fail if worst comes
to worst than not doing anything at all. At least by attempting to
implement that, I will
have a better understanding of LLVM code base which may come in handy to
to other parts of LLVM.
Thanks and regards,
