[LLVMdev] Dynamically alternating between register allocators

[Fernando Magno Quintao Pereira]

Hey all,

     is there a simple way to alternate between different register 
allocators at run time? I would like to decide dynamically which register 
allocator to use. The decision is based on information that is produced by 
a pass that executes before register allocation takes place.

Is it possible to modify RegisterRegAlloc::Registry to take into 
consideration this information? Is there any similar example in LLVM?

all the best,

Fernando
