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 -gvn -S \| grep load \| count 2`
Add basic support for performing whole-function RLE. Note: This has not yet been thoroughly tested. Use at your own risk. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@40489 91177308-0d34-0410-b5e6-96231b3b80d8 2007-07-25 19:57:03 +00:00

make GVN try to rename inputs to the resultant replaced values, which cleans up the generated code a bit. This should have the added benefit of not randomly renaming functions/globals like my previous patch did. :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61023 91177308-0d34-0410-b5e6-96231b3b80d8 2008-12-15 03:46:38 +00:00			`%c = load i32** %p`

Convert tests using "\| wc -l \| grep ..." to use the count script. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@41097 91177308-0d34-0410-b5e6-96231b3b80d8 2007-08-15 13:36:28 +00:00			`}`
