You want a test that issues one error but not another?

I'd do something like:

; RUN: not llc <blah blah> < %s 2> %t | FileCheck %s
; RUN: FileCheck --check-prefix=CHECK-ERRORS < %t %s

; CHECK: normal output check here
; CHECK-ERRORS: my-diagnostic-here

Perhaps with some CHECK-ERRORS-NOT and CHECK-NOT, too.
