Dear Chandler, > Please let me know if you have out-of-tree users of this logic At KernelGen we have an out-of-tree variation of CodeExractor called BranchedCodeExractor [1], which instead of taking a code region into a new function, does it conditionally: ORIGINAL_CODE; ->> if (extracted_code_function(args) != -1) { ORIGINAL_CODE; } I think many hybrid and parallelizing tools
