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 -ipsccp -S \| grep -v {ret i101 0} \| \`
For PR1319: Upgrade to use new Tcl exec based test harness. This exposes 3 bugs that were previously not being reported: test/Transforms/GlobalDCE/2002-08-17-FunctionDGE.ll test/Transforms/GlobalOpt/memset.ll test/Transforms/IndVarsSimplify/exit_value_tests.llx git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@36065 91177308-0d34-0410-b5e6-96231b3b80d8 2007-04-15 09:21:47 +00:00			`; RUN: grep -v {ret i101 undef} \| not grep ret`
Add the SCCP regression tests for APInt expressions. These test cases turned up some regressions that have since been fixed. We don't want to loose the regression tests.
