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 -instcombine -S > %t`
Make opt default to not adding a target data string and update tests that depend on target data to supply it within the test git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85900 91177308-0d34-0410-b5e6-96231b3b80d8 2009-11-03 15:29:06 +00:00			`target datalayout = "E-p:64:64:64-a0:0:8-f32:32:32-f64:64:64-i1:8:8-i8:8:8-i16:16:16-i32:32:32-i64:32:64-v64:64:64-v128:128:128"`
canonicalize inttoptr and ptrtoint instructions which cast pointers to/from integer types that are not intptr_t to convert to intptr_t then do an integer conversion to the dest type. This exposes the cast to the optimizer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@67638 91177308-0d34-0410-b5e6-96231b3b80d8 2009-03-24 18:35:40 +00:00
