It's not quite that simple, at least under windows: https://docs.microsoft.com/en-us/cpp/build/prolog-and-epilog But yes, this documents that there can be multiple epilogues, so the additional ret would be fine in this regard. Following this exact format is required so that the stack unwinder during processing of SEH (structured exception handling) which is performed by the OS can correctly restore the value of non-volatile registers that has been saved on the stack. Fortunately, as our function in this case doesn't use the stack at all and doesn't contain calls to other functions, this can be skipped. > So what happens now? Do we submit a patch? I think Sven Barth was going to fix this up anyway?
