2012-04-10ARM fix cc_out operand handling for t2SUBrr instructions.Jim Grosbach
We were incorrectly conflating some add variants which don't have a cc_out operand with the mirroring sub encodings, which do. Part of the awesome non-orthogonality legacy of thumb1. Similarly, handling of add/sub of an immediate was sometimes incorrectly removing the cc_out operand for add/sub register variants. rdar://11216577 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@154411 91177308-0d34-0410-b5e6-96231b3b80d8

2012-04-10Fix a long standing tail call optimization bug. When a libcall is emittedEvan Cheng
legalizer always use the DAG entry node. This is wrong when the libcall is emitted as a tail call since it effectively folds the return node.
