I think you might want to search using "profile guided optimization" (or
"PGO"), "compiler", and "parallel".


You may find something in the compiler research done for EPIC
processors, since profiling and VLIW-style parallelism is (was)
fundamental to these architectures.


Here are a few sample Google hits that may be of interest:
