Any help / suggestions are most welcome. efg @main(%data: r[(1, 2, 4, 4), float32], %param_1: or[(2, 1, 5, 5), float32], %param_2: or[(20), float32], %param_3: or[(5, 2, 5, 5), float32], %param_4: or[(50), float32], %param_5: or[(50, 80), float32], %param_6: Tensor[(50), float32], %param_7: or[(10, 50), float32], %param_8: or[(20), float32] Best Regards, Archana Deshmukh [This looks very straightforward. The Flex tokens are keywords, numbers, and punctuation, the bison rules would be a %param or %data expression, a list of such expressions, and so on. Is there some particular problem you are encountering? -John Cheap plug: there's always my book https://amzn.to/3IrtPFS ]
