* Get rid of an optimization in SCCP which appears to have many issues. ↵Eli Friedman2011-11-112-187/+1
| | | | | | | | | | | | Specifically, it doesn't handle many cases involving undef correctly, and it is missing other checks which lead to it trying to re-mark a value marked as a constant with a different value. It also appears to trigger very rarely. Fixes PR11357. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@144352 91177308-0d34-0410-b5e6-96231b3b80d8

* Use a bigger hammer to fix PR11314 by disabling the "forcing two-addressEvan Cheng2011-11-1012-21/+36
| | | | | | | | | | | | | | | | | instruction lower optimization" in the pre-RA scheduler. The optimization, rather the hack, was done before MI use-list was available. Now we should be able to implement it in a better way, perhaps in the two-address pass until a MI scheduler is available. Now that the scheduler has to backtrack to handle call sequences. Adding artificial scheduling constraints is just not safe. Furthermore, the hack is not taking all the other scheduling decisions into consideration so it's just as likely to pessimize code. So I view disabling this optimization goodness regardless of PR11314. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@144267 91177308-0d34-0410-b5e6-96231b3b80d8
