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. llvm-svn: 81537

Teach IndVarSimplify's FixUsesBeforeDefs to handle InvokeInsts by assuming that the use of the value is in a block dominated by the "normal" destination. LangRef.html and other documentation sources don't explicitly guarantee this, but it seems to be assumed in other places in LLVM at least. This fixes an assertion failure on the included testcase, which is derived from the Ada testsuite. FixUsesBeforeDefs is a temporary measure which I'm looking to replace with a more capable solution. llvm-svn: 72266

Teach IndVarSimplify's FixUsesBeforeDefs to handle InvokeInsts by assuming that the use of the value is in a block dominated by the "normal" destination. LangRef.html and other documentation sources don't explicitly guarantee this, but it seems to be assumed in other places in LLVM at least. This fixes an assertion failure on the included testcase, which is derived from the Ada testsuite. FixUsesBeforeDefs is a temporary measure which I'm looking to replace with a more capable solution. llvm-svn: 72266
