Olivier, I don’t really understand this heuristics. It looks like you are adding lots of code to handle a very specific case and I am not convinced that this heuristics is useful for the general case.
Following Hal’s suggestion to benchmark this patch is a really good idea. Do you know how it affects the LLVM test suite? Are you seeing any gains or regressions?
