There is also a good blog post about the greedy allocator (default when optimizing): http://blog.llvm.org/2011/09/greedy-register-allocation-in-llvm-30.html <http://blog.llvm.org/2011/09/greedy-register-allocation-in-llvm-30.html>

but to really learn the details you have to read the sourcecode.

AFAIK, you can refer previous LLVMDevs' slides to get a general idea on spilling, - http://llvm.org/devmtg/2008-08/ChengRegisterAllocation.pdf - http://llvm.org/devmtg/2009-10/RegisterAllocationFutureWorks.pdf - http://llvm.org/devmtg/2011-11/OlesenRegisterAllocation.pdf But I don't know if there is article describing spilling in detail around.

I am interested in the spill code which is produced by the register allocators. Therefore I wanted to ask if there is some Documentation in which these allocators are described, or that explains how the register spilling works in detail. Regards Jannis
