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 2009-09-11 20:01:28 +02:00			`; RUN: opt < %s -instcombine -S \| not grep icmp`
Don't restrict the set of instructions where we try to constant-fold the operands; it's possible to end up with a constant-foldable operand to most instructions, even those which can't trap. llvm-svn: 75845 2009-07-16 00:13:34 +02:00
