2007-06-261. Correct some comments and clean up some dead code.Owen Anderson
2. When calculating ANTIC_IN, only iterate the changed blocks. For most average inputs this is a small speedup, but for cases with unusual CFGs, this can be a significant win. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@37742 91177308-0d34-0410-b5e6-96231b3b80d8

2007-06-25Generalize MVT::ValueType and associated functions to be able to representDan Gohman
extended vector types. Remove the special SDNode opcodes used for pre-legalize vector operations, and the special MVT::Vector type used with them. Adjust lowering and legalize to work with the normal SDNode kinds instead, and to use the normal MVT functions to work with vector types instead of using the two special operands that the pre-legalize nodes held. This allows pre-legalize and post-legalize DAGs, and the code that operates on them, to be more consistent. Pre-legalize vector operators can be handled more consistently with scalar operators. And, -view-dag-combine1-dags and -view-legalize-dags now look prettier for vector code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@37719 91177308-0d34-0410-b5e6-96231b3b80d8

2007-06-251) Fix an issue with non-deterministic iteration order in phi_translateOwen Anderson
2) Remove some maximal-set computing code that is no longer used. 3) Use a post-order CFG traversal to compute ANTIC_IN instead of a postdom traversal. This causes the ANTIC_IN calculation to converge much faster. Thanks to Daniel Berlin for suggesting this. With this patch, the time to optimize 403.gcc decreased from 17.5s to 7.5s, and Anton's huge testcase decreased from 62 minutes to 38 seconds. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@37714 91177308-0d34-0410-b5e6-96231b3b80d8
