[llvm-dev] Writing tests with Filecheck without emitting output to stdin

[Mahesh Attarde via llvm-dev]

That works. Thanks.

One more followup question though.
Once i run opt on bitcode, there is not useful output/transform on bitcode.
this rpt files are extra.
I am hoping to do something like this,

; RUN: FileCheck  --input-file=a.rpt.gold --check-prefix=CHECK-A < a.rpt
; RUN: FileCheck  --input-file=b.rpt.gold --check-prefix=CHECK-B < b.rpt

i did not find much examples in tests hence question.
does this have any potential issue in matching.
