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			`; RUN: llvm-as < %s \| opt -gvn \| llvm-dis \| 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
