I made backport of "Fix a bug in mayHaveSideEffects. Functions that do not return are now considered as instructions with side effects." (http://llvm.org/viewvc/llvm-project?view=revision&revision=175553) to llvm 3.1 and found that test from this fix contained incorrect "CHECK: ret". This CHECK doesn't find ret but finds the word "noreturn" in attributes, so FileCheck passes.

; Function Attrs: noreturn nounwind ssp uwtable
define i32 @main() #1 {
entry:
  tail call void @endless_loop()
  unreachable
}

attributes #0 = { noreturn nounwind readnone ssp uwtable }
attributes #1 = { noreturn nounwind ssp uwtable }

The llvm 3.1 doesn't make attributes, so I found this inaccuracy.
