[PATCH] D16481: Split PrologEpilogInserter into 2 parts

[Derek Schuff via llvm-commits]

dschuff added a comment.

Another option might be to use a similar factoring (which splits the code that must deal with virtual registers out from the code that need not), but not actually create 2 different MachineFunctionPasses. We could say that the pass itself supports virtual registers, but we'd have better organization and clearer separation.
