[LLVMdev] TableGen related question for the Hexagon backend
...n backend, a predicated instruction can translate into another
form called 'predicate new'. So, in our example of 'ADD', we can have
another transformation like this -
ADD--- ---> ADDtrue -----> ADDtru_new (predicate new form of true)
\-----> ADDfalse -----> ADDfalse_new (predicate new form of false)
// Define Predicate New relation
def getPredNewOpcode : InstrMapping {
let FilterClass = "PredNewRel";
let RowFields = ["BaseOpcode"];
// ColFields is a list of flags/attributes of the instructions.
let ColFields = ["DotNewType",...

Hi Jacob,
Thanks for the suggestions. I have a few questions here.

Are you saying that the mechanism is already present which allows us to
relate
