Thank you for you reply! This my first revision and I misunderstood the meaning of "baseline check"

This means I should first update the diff of test IRs in this baseline check revision without my patch, i.e. output IR should be the same as input IR;  
then apply my patch to the code and expect we would gain optimizations, i.e. output IR optimized and differ from input IR?
Is this correct?
