[llvm-dev] Manipulate Register allocation in basic block level

Is it possible to annotate basic blocks in order to manipulate them in
LLVM backend with fine granularity?

 Eg: I want to reserve registers for some parts of the code, therefore
need to stop register allocator from using some registers only in
specific basic blocks.
