Member Function Documentation

◆ dotString()

std::string MIDDGNode::dotString ( ) const

virtual

Returns the string that should be placed in the node's properties section in the GraphViz Dot string.

This can be overridden in the derived class to add different properties (e.g., colors, etc.) to different type of nodes. The default implementation only sets the label property.

Returns: String describing the Dot properties of the Node.

Reimplemented from GraphNode.

◆ osalOperationName()

TCEString MIDDGNode::osalOperationName ( ) const

Try to figure out the name of the instruction opcode in OSAL, if available.

If the operation with the produced name is not found in OSAL, llvm: is prepended to the name string.
