Add warning for falling off the end of a function that should return a value. This is on by default, and controlled by -Wreturn-type (-Wmost -Wall). I believe there should be very few false positives, though the most interesting case would be: int() { bar(); } when bar does: bar() { while (1) ; } Here, we assume functions return, unless they are marked with the noreturn attribute. I can envision a fixit note for functions that never return normally that don't have a noreturn attribute to add a noreturn attribute. If anyone spots other false positives, let me know! llvm-svn: 76821 2009-07-23 07:56:57 +08:00			`// RUN: clang-cc %s -fsyntax-only -verify`
