* Provide two overloads of AnalyzeNewNode.Gabor Greif2008-09-012-17/+24
| | | | | | | | | | | | The first can update the SDNode in an SDValue while the second is called with SDNode* and returns a possibly updated SDNode*. This patch has no intended functional impact, but helps eliminating ugly temporary SDValues. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55608 91177308-0d34-0410-b5e6-96231b3b80d8
* Even though no caller actually uses the new valueDuncan Sands2008-09-011-1/+2
| | | | | | | | (what matters is that it is added to the worklist), it seems more logical to return it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55606 91177308-0d34-0410-b5e6-96231b3b80d8
* Add a small pass that sets the readnone/readonlyDuncan Sands2008-09-011-0/+69
| | | | | | | | | | | | | | | | | | | | | | | | | | attributes on functions, based on the result of alias analysis. It's not hardwired to use GlobalsModRef even though this is the only (AFAIK) alias analysis that results in this pass actually doing something. Enable as follows: opt ... -globalsmodref-aa -markmodref ... Advantages of this pass: (1) records the result of globalsmodref in the bitcode, meaning it is available for use by later passes (currently the pass manager isn't smart enough to magically make an advanced alias analysis available to all later passes), which may expose more optimization opportunities; (2) hopefully speeds up compilation when code is optimized twice, for example when a file is compiled to bitcode, then later LTO is done on it: marking functions readonly/readnone when producing the initial bitcode should speed up alias analysis during LTO; (3) good for discovering that globalsmodref doesn't work very well :) Not currently turned on by default. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55604 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix an issue where a use might be selected before a def, and then we didn't ↵Owen Anderson2008-08-301-8/+23

Other solutions might be preferable, such as: 1) Passing the dest reg into FastEmit_. However, this would require the higher level code to know about reg classes, which they don't currently. 2) Selecting blocks in reverse postorder. This has some compile time cost for computing the order, and we'd need to measure its impact. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55555 91177308-0d34-0410-b5e6-96231b3b80d8
