After finishing the output should be read into R and used for further calculation. Under windows, it perfectly works: result<-shell("gencont < yn.txt",intern=TRUE,wait=TRUE) # R waits untill the program finishes (apporx 3 min) and

Hi David, The only reason I can see to use the 'pattern matching' part as a fall-back is in case we cannot inline the (what I'm assuming would be) a much bigger hot-path-only cloned function for whatever reason. What I'm assuming here is that after cold-region outlining, we may still have a large portion of the original function body to attempt to inline, whereas the pattern
