Change tests from "opt %s" to "opt < %s" so that opt doesn't see the input filename so that opt doesn't print the input filename in the output so that grep lines in the tests don't unintentionally match strings in the input filename. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81537 91177308-0d34-0410-b5e6-96231b3b80d8 2009-09-11 18:01:28 +00:00			`; RUN: opt < %s -inline -simplify-libcalls -functionattrs \| \`
Reapply r64300: Make sure the SCC pass manager initializes any contained function pass managers. Without this, simplify-libcalls would add nocapture attributes when run on its own, but not when run as part of -std-compile-opts or similar. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@64443 91177308-0d34-0410-b5e6-96231b3b80d8 2009-02-13 07:15:53 +00:00			`; RUN: llvm-dis \| grep nocapture \| count 2`
