[llvm-dev] Register Allocators Documentation

[Matthias Braun via llvm-dev]

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.
