| * | Fix a serious X86 instruction selection bug. In | Evan Cheng | 2012-10-02 |
| X86DAGToDAGISel::PreprocessISelDAG(), isel is moving load inside callseq_start / callseq_end so it can be folded into a call. This can create a cycle in the DAG when the call is glued to a copytoreg. We have been lucky this hasn't caused too many issues because the pre-ra scheduler has special handling of call sequences. However, it has caused a crash in a specific tailcall case. rdar://12393897 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165072 91177308-0d34-0410-b5e6-96231b3b80d8 | |||
