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

[Mahesh Attarde via llvm-dev]

Hello
 I have pass operating on  bitcode file which produces more than one
equivalent representation.

opt --my-pass <%s | Filecheck  %s

--my-pass generates  files a.rpt b.rpt c.rpt . How do i write test without
writing all 3 files to stdin.

I have considered CHECK-LABEL for each. it creates bulky checks.


Thanks
Mahesh
