...ver, assertion messages are static strings, and don't include any information about the particular object/value which caused the assertion. In a 'data oriented' system like llvm, this makes it really difficult to pinpoint which node is actually triggering the assertion. For example, in ScheduleDAGSDNodesEmit.cpp (lib/CodeGen/SelectionDAG/), in the ScheduleDAGSDNodes::AddOperand method, there is the following assert: assert(Op.getValueType() !=MVT::Other && Op.getValueType() != MVT::Flag && "Chain and flag operands should occur at end of operand list!"); In order to understan...

Hello, Everyone > TargetSelectoinDAG.td and then why the two versions are "identical" in > TableGen's mind. That's correct. The patterns are identical since the types of operands involved are the same. DAG pattern matching is done before regalloc, there are not regclasses actually at that point, thus both patterns tries to select the same thing... -- With best regards,

Hi, I am writing a backend for the Blackfin processor from Analog Devices. I just started so I still have a lot to learn about the code generator. So far, I can compile test/CodeGen/Generic/BasicInstrs.ll correctly, but that is about it. The Blackfin 32-bit registers divide naturally into several classes. I have modelled these register classes without knowing anything about what the code
