...surprised to find that the structure of MatcherTable and the interpreter seems to be suitable for parallelization. So we propose a prototype that parallelizes the interpreting of OPC_Scope children that are possibly time-consuming. Here is some quick overview: We add two new opcodes: OPC_Fork and OPC_Merge. During DAG optimization process(utils/TableGen/DAGISelMatcherOpt.cpp). OPC_Fork would be added to the front of scope(OPC_Scope) children which fulfill following conditions: 1. Amount of opcodes within the child exceed certain threshold(5 in current prototype). 2. The child is reside in a sequenc...
