[PATCH] D17257: New utility class ReachingPhysDefs for post-ra analysis.

[Krzysztof Parzyszek via llvm-commits]

kparzysz added a comment.

The RDF actually creates a data-flow graph for physical registers.  It's currently under lib/Target/Hexagon/, but it was written as target-independent.  Its only current limitation is lack of handling of regmasks, but that can be added fairly easily.
