Evan Cheng 481c8e0501 At top of generated isel SelectCode() is this: ... if (!N.Val->hasOneUse()) { std::map<SDOperand, SDOperand>::iterator CGMI = CodeGenMap.find(N); if (CGMI != CodeGenMap.end()) return CGMI->second; } Suppose a DAG like this: X ^ ^ / \ USE1 USE2 Suppose USE1 is being selected first and during which X is selected and returned a new node. After this, USE1 is no longer an use of X. During USE2 selection, X will be selected again since it has only one use! The fix is to always query CodeGenMap. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24679 91177308-0d34-0410-b5e6-96231b3b80d8		2005-12-12 23:22:48 +00:00
