Change to "...metadata: !foo" to check reporting of metadata type?

Not sure what you mean?  What is "...metadata:" ?

[Mark Seaborn, 2013/04/25 23:25:50]

I meant you can change it to:
"; CHECK: Function types has disallowed instruction metadata: foo"

[jvoung (off chromium), 2013/04/26 16:51:29]

Done.

   ret void, !foo !0
 }
 ; CHECK-NOT: disallowed
