Evan Cheng 623a7e146b Use a bigger hammer to fix PR11314 by disabling the "forcing two-address ... 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		2011-11-10 07:43:16 +00:00
